The man smiled. He seemed a superior type to the others and was evidently a foreman.

"Not so bad, monsieur. We have four saws, but only two are running today." He pointed to the door behind him as he spoke, and the two friends passed in as if to have an idle look round.

The interior was fitted up like that of any other sawmill, but the same element of design and efficiency seemed apparent here as elsewhere. The foreman explained the process. The lopped trunks from the wood came in by one of two roads through a large door in the center of the building. Outside each road was a saw, its axle running parallel to the roads. The logs were caught in grabs, slung on to the table of the saws and, moving automatically all the time, were cut into lengths of from seven to ten feet. The pieces passed for props were dumped on to a conveyor which ran them out of the shed to be stacked for seasoning and export. The rejected pieces by means of another conveyor moved to the third and fourth saws, where they were cut into blocks for firewood, being finally delivered into two large bins ready for loading on to the lorries.

The friends exhibited sufficient non-technical interest to manage to spend a good deal of time over their survey, drawing out the foreman in conversation and seeing as much as they could. At one end of the shed was the boiler house and engine room, at the other the office, with between it and the mill proper a spacious garage in which, so they were told, the six lorries belonging to the syndicate were housed. Three machines were there, two lying up empty, the third, with engine running and loaded with blocks, being ready to start. They would have liked to examine the number plate, but in the presence of the foreman it was hardly possible. Finally they walked across the clearing to where felling and lopping was in progress, and inspected the operations. When they left shortly after with a promise to return to meet Mr. Coburn, there was not much about the place they had missed.

"That business is just as right as rain," Merriman declared when they were once more in the boat. "And that foreman's all right too. I'd stake my life he wasn't hiding anything. He's not clever enough for one thing."

"So I think too," Hilliard admitted. "And yet, what about the game with the number plates? What's the idea of that?"

"I don't know. But all the same I'll take my oath there's nothing wrong about the timber trade. It's no go, Hilliard. Let's drop chasing wild geese and get along with our trip."

"I feel very like it," the other replied as he sucked moodily at his pipe. "We'll watch for another day or so, and if we see nothing suspicious we can clear out."

But that very evening an incident occurred which, though trifling, revived all their suspicions and threw them at once again into a sea of doubt.

Believing that the Coburns would by that time have returned, they left the launch about five o'clock to call. Reaching the edge of the clearing almost directly behind the house, they passed round the latter and rang.

The door was opened by Miss Coburn herself. It happened that the sun was shining directly in her eyes, and she could not therefore see her visitors' features.

"You are the gentlemen who wished to see Mr. Coburn, I presume?" she said before Merriman could speak. "He is at the works. You will find him in his office."

Merriman stepped forward, his cap off.

"Don't you remember me, Miss Coburn?" he said earnestly. "I had the pleasure of meeting you in May, when you were so kind as to give me petrol to get me to Bordeaux."

Miss Coburn looked at him more carefully, and her manner, which had up to then been polite, but coolly self-contained, suddenly changed. Her face grew dead white and she put her hand sharply to her side, as though to check the rapid beating of her heart. For a moment she seemed unable to speak, then, recovering herself with a visible effort, she answered in a voice that trembled in spite of herself:

"Mr. Merriman, isn't it? Of course I remember. Won't you come in? My father will be back directly."

She was rapidly regaining self-control, and by the time Merriman had presented Hilliard her manner had become almost normal. She led the way to a comfortably furnished sitting-room looking out over the river.

"Hilliard and I are on a motor launch tour across France," Merriman went on. "He worked from England down the coast to Bordeaux, where I joined him, and we hope eventually to cross the country to the Mediterranean and do the Riviera from the sea."

"How perfectly delightful," Miss Coburn replied. "I envy you."

"Yes, it's very jolly doing these rivers and canals," Hilliard interposed. "I have spent two or three holidays that way now, and it has always been worth while."

As they chatted on in the pleasant room the girl seemed completely to have recovered her composure, and yet Merriman could not but realize a constraint in her manner, and a look of anxiety in her clear brown eyes. That something was disturbing her there could be no doubt, and that something appeared to be not unconnected with himself. But, he reasoned, there was nothing connected with himself that could cause her anxiety, unless it really was that matter of the number plates. He became conscious of an almost overwhelming desire to share her trouble whatever it might be, to let her understand that so far from willingly causing a shadow to fall across her path there were few things he would not do to give her pleasure; indeed, he began to long to take her in his arms, to comfort her....

Presently a step in the hall announced Mr. Coburn's return. "In here, daddy," his daughter called, and the steps approached the door.

Whether by accident or design it happened that Miss Coburn was seated directly opposite the door, while her two visitors were placed where they were screened by the door itself from the view of anyone entering. Hilliard, his eyes on the girl's face as her father came in, intercepted a glance of what seemed to be warning. His gaze swung round to the new-comer, and here again he noticed a start of surprise and anxiety as Mr. Coburn recognized his visitor. But in this case it was so quickly over that had he not been watching intently he would have missed it. However, slight though it was, it undoubtedly seemed to confirm the other indications which pointed to the existence of some secret in the life of these two, a secret shared apparently by the good-looking driver and connected in some way with the lorry number plates.

Mr. Coburn was very polite, suave and polished as an accomplished man of the world. But his manner was not really friendly; in fact, Hilliard seemed to sense a veiled hostility. A few deft questions put him in possession of the travelers ostensible plans, which he discussed with some interest.

"But," he said to Hilliard, "I am afraid you are in error in coming up this River Lesque. The canal you want to get from here is the Midi, it enters the Mediterranean not far from Narbonne. But the connection from this side is from the Garonne. You should have gone up-stream to Langon, nearly forty miles above Bordeaux."

"We had hoped to go from still farther south," Hilliard answered. "We have penetrated a good many of the rivers, or rather I have, and we came up here to see the sand-dunes and forests of the Landes, which are new to me. A very desolate country, is it not?"

Mr. Coburn agreed, continuing courteously:

"I am glad at all events that your researches have brought you into our neighborhood. We do not come across many visitors here, and it is pleasant occasionally to speak one's own language to someone outside one's household. If you will put up with pot-luck I am sure we should both be glad—" he looked at his daughter"—if you would wait and take some dinner with us now. Tomorrow you could explore the woods, which are really worth seeing though monotonous, and if you are at all interested I should like to show you our little works. But I warn you the affair is my hobby, as well as my business for the time being, and I am apt to assume others have as great an interest in it as myself. You must not let me bore you."

Hilliard, suspicious and critically observant, wondered if he had not interrupted a second rapid look between father and daughter. He could not be sure, but at all events the girl hastened to second her father's invitation.

"I hope you will wait for dinner," she said. "As he says, we see so few people, and particularly so few English, that it would be doing us a kindness. I'm afraid that's not very complimentary"—she laughed brightly—"but it's at least true."

They stayed and enjoyed themselves. Mr. Coburn proved himself an entertaining host, and his conversation, though satirical, was worth listening to. He and Hilliard talked, while Merriman, who was something of a musician, tried over songs with Miss Coburn. Had it not been for an uneasy feeling that they were to some extent playing the part of spies, the evening would have been a delight to the visitors.

Before they left for the launch it was arranged that they should stay over the following day, lunch with the Coburns, and go for a tramp through the forest in the afternoon. They took their leave with cordial expressions of good will.

"I say, Merriman," Hilliard said eagerly as they strolled back through the wood, "did you notice how your sudden appearance upset them both? There can be no further doubt about it, there's something. What it may be I don't know, but there is something."

"There's nothing wrong at all events," Merriman asserted doggedly.

"Not wrong in the sense you mean, no," Hilliard agreed quickly, "but wrong for all that. Now that I have met Miss Coburn I can see that your estimate of her was correct. But anyone with half an eye could see also that she is frightened and upset about something. There's something wrong, and she wants a helping hand."

"Damn you, Hilliard, how you talk," Merriman growled with a sudden wave of unreasoning rage. "There's nothing wrong and no need for our meddling. Let us clear out and go on with our trip."

Hilliard smiled under cover of darkness.

"And miss our lunch and excursion with the Coburns to-morrow?" he asked maliciously.

"You know well enough what I mean," Merriman answered irritably. "Let's drop this childish tomfoolery about plots and mysteries and try to get reasonably sane again. Here," he went on fiercely as the other demurred, "I'll tell you what I'll do if you like. I'll have no more suspicions or spying, but I'll ask her if there is anything wrong: say I thought there was from her manner and ask her the direct question. Will that please you?"

"And get well snubbed for your pains?" Hilliard returned. "You've tried that once already. Why did you not persist in your inquiries about the number plate when she told you about the driver's shell-shock?"

Merriman was silent for a few moments, then burst out:

"Well, hang it all, man, what do you suggest?"

During the evening an idea had occurred to Hilliard and he returned to it now.

"I'll tell you," he answered slowly, and instinctively he lowered his voice. "I'll tell you what we must do. We must see their steamer loaded. I've been thinking it over. We must see what, if anything, goes on board that boat beside pit-props."

Merriman only grunted in reply, but Hilliard, realizing his condition, was satisfied.

And Merriman, lying awake that night on the port locker of the Swallow, began himself to realize his condition, and to understand that his whole future life and happiness lay between the dainty hands of Madeleine Coburn.



CHAPTER 5. THE VISIT OF THE "GIRONDIN"

Next morning found both the friends moody and engrossed with their own thoughts.

Merriman was lost in contemplation of the new factor which had come into his life. It was not the first time he had fancied himself in love. Like most men of his age he had had affairs of varying seriousness, which in due time had run their course and died a natural death. But this, he felt, was different. At last he believed he had met the one woman, and the idea thrilled him with awe and exultation, and filled his mind to the exclusion of all else.

Hilliard's preoccupation was different. He was considering in detail his idea that if a close enough watch could be kept on the loading of the syndicate's ship it would at least settle the smuggling question. He did not think that any article could be shipped in sufficient bulk to make the trade pay, unnoticed by a skilfully concealed observer. Even if the commodity were a liquid—brandy, for example—sent aboard through a flexible pipe, the thing would be seen.

But two unexpected difficulties had arisen since last night. Firstly, they had made friends with the Coburns. Excursions with them were in contemplation, and one had actually been arranged for that very day. While in the neighborhood they had been asked virtually to make the manager's house their headquarters, and it was evidently expected that the two parties should see a good deal of each other. Under these circumstances how were the friends to get away to watch the loading of the boat?

And then it occurred to Hilliard that here, perhaps, was evidence of design; that this very difficulty had been deliberately caused by Mr. Coburn with the object of keeping himself and Merriman under observation and rendering them harmless. This, he recognized, was guesswork, but still it might be the truth.

He racked his brains to find some way of meeting the difficulty, and at last, after considering many plans, he thought he saw his way. They would as soon as possible take leave of their hosts and return to Bordeaux, ostensibly to resume their trip east. From there they would come out to the clearing by road, and from the observation post they had already used keep a close eye on the arrival of the ship and subsequent developments. At night they might be even able to hide on the wharf itself. In any case they could hardly fail to see if anything other than pit-props was loaded.

So far, so good, but there was a second and more formidable difficulty. Would Merriman consent to this plan and agree to help? Hilliard was doubtful. That his friend had so obviously fallen in love with this Madeleine Coburn was an unexpected and unfortunate complication. He could, of course, play on the string that the girl was in danger and wanted help, but he had already used that with disappointing results. However, he could see nothing for it but to do his best to talk Merriman round.

Accordingly, when they were smoking their after-breakfast pipes, he broached the subject. But as he had feared, his friend would have none of it.

"I tell you I won't do anything of the kind," he said angrily. "Here we come, two strangers, poking our noses into what does not concern us, and we are met with kindness and hospitality and invited to join a family party. Good Lord, Hilliard, I can't believe that it is really you that suggests it! You surely don't mean that you believe that the Coburns are smuggling brandy?"

"Of course not, you old fire-eater," Hilliard answered good-humoredly, "but I do believe, and so must you, that there is something queer going on. We want to be sure there is nothing sinister behind it. Surely, old man, you will help me in that?"

"If I thought there was anything wrong you know I'd help you," Merriman returned, somewhat mollified by the other's attitude. "But I don't. It is quite absurd to suggest the Coburns are engaged in anything illegal, and if you grant that your whole case falls to the ground."

Hilliard saw that for the moment at all events he could get no more. He therefore dropped the subject and they conversed on other topics until it was time to go ashore.

Lunch with their new acquaintances passed pleasantly, and after it the two friends went with Mr. Coburn to see over the works. Hilliard thought it better to explain that they had seen something of them on the previous day, but notwithstanding this assurance Mr. Coburn insisted on their going over the whole place again. He showed them everything in detail, and when the inspection was complete both men felt more than ever convinced that the business was genuine, and that nothing was being carried on other than the ostensible trade. Mr. Coburn, also, gave them his views on the enterprise, and these seemed so eminently reasonable and natural that Hilliard's suspicions once more became dulled, and he began to wonder if their host's peculiar manner could not have been due to some cause other than that he had imagined.

"There is not so much money in the pit-props as I had hoped," Mr. Coburn explained. "When we started here the Baltic trade, which was, of course, the big trade before the war, had not revived. Now we find the Baltic competition growing keener, and our margin of profit is dwindling. We are handicapped also by having only a one-way traffic. Most of the Baltic firms exporting pit-props have an import trade in coal as well. This gives them double freights and pulls down their overhead costs. But it wouldn't pay us to follow their example. If we ran coal it could only be to Bordeaux, and that would take up more of our boat's time than it would be worth."

Hilliard nodded and Mr. Coburn went on:

"On the other hand, we are doing better in what I may call 'sideshows.' We're getting quite a good price for our fire-wood, and selling more and more of it. Three large firms in Bordeaux have put in wood-burning fireboxes and nothing else, and two others are thinking of following suit. Then I am considering two developments; in fact, I have decided on the first. We are going to put in an air compressor in our engine-room, and use pneumatic tools in the forest for felling and lopping. I estimate that will save us six men. Then I think there would be a market for pine paving blocks for streets. I haven't gone into this yet, but I'm doing so."

"That sounds very promising," Hilliard answered. "I don't know much about it, but I believe soft wood blocks are considered better than hard."

"They wear more evenly, I understand. I'm trying to persuade the Paris authorities to try a piece of it, and if that does well it might develop into a big thing. Indeed, I can imagine our giving up the pit-props altogether in the future."

After a time Miss Coburn joined them, and, the Ford car being brought out, the party set off on their excursion. They visited a part of the wood where the trees were larger than near the sawmill, and had a pleasant though uneventful afternoon. The evening they spent as before at the Coburns' house.

Next day the friends invited their hosts to join them in a trip up the river. Hilliard tactfully interested the manager in the various "gadgets" he had fitted up in the launch, and Merriman's dream of making tea with Miss Coburn materialized. The more he saw of the gentle, brown-eyed girl, the more he found his heart going out to her, and the more it was borne in on him that life without her was becoming a prospect more terrible than he could bring himself to contemplate.

They went up-stream on the flood tide for some twenty miles, until the forest thinned away and they came on vineyards. There they went ashore, and it was not until the shades of evening were beginning to fall that they arrived back at the clearing.

As they swung round the bend in sight of the wharf Mr. Coburn made an exclamation.

"Hallo!" he cried. "There's the Girondin. She has made a good run. We weren't expecting her for another three or four hours."

At the wharf lay a vessel of about 300 tons burden, with bluff, rounded bows sitting high up out of the water, a long, straight waist, and a bridge and cluster of deckhouses at the stern.

"Our motor ship," Mr. Coburn explained with evident pride. "We had her specially designed for carrying the pit-props, and also for this river. She only draws eight feet. You must come on board and have a look over her."

This was of all things what Hilliard most desired. He recognized that if he was allowed to inspect her really thoroughly, it would finally dispel any lingering suspicion he might still harbor that the syndicate was engaged in smuggling operations. The two points on which that suspicion had been founded—the absence of return cargoes and the locality of the French end of the enterprise—were not, he now saw, really suspicious at all. Mr. Coburn's remark met the first of these points, and showed that he was perfectly alive to the handicap of a oneway traffic. The matter had not been material when the industry was started, but now, owing to the recovery of the Baltic trade after the war, it was becoming important, and the manager evidently realized that it might easily grow sufficiently to kill the pit-prop trade altogether. And the locality question was even simpler. The syndicate had chosen the pine forests of the Landes for their operations because they wanted timber close to the sea. On the top of these considerations came the lack of secrecy about the ship. It could only mean that there really was nothing aboard to conceal.

On reaching the wharf all four crossed the gangway to the deck of the Girondin. At close quarters she seemed quite a big boat. In the bows was a small forecastle, containing quarters for the crew of five men as well as the oil tanks and certain stores. Then amidships was a long expanse of holds, while aft were the officers' cabins and tiny mess-room, galley, navigating bridge, and last, but not least, the engine-room with its set of Diesel engines. She seemed throughout a well-appointed boat, no money having apparently been spared to make her efficient and comfortable.

"She carries between six and seven thousand props every trip," Mr. Coburn told them, "that is, without any deck cargo. I dare say in summer we could put ten thousand on her if we tried, but she is rather shallow in the draught for it, and we don't care to run any risks. Hallo, captain! Back again?" he broke off, as a man in a blue pilot cloth coat and a peaked cap emerged from below.

The newcomer was powerfully built and would have been tall, but for rather rounded shoulders and a stoop. He was clean shaven, with a heavy jaw and thin lips which were compressed into a narrow line. His expression was vindictive as well as somewhat crafty, and he looked a man who would not be turned from his purpose by nice points of morality or conscience.

Though Hilliard instinctively noted these details, they did not particularly excite his interest. But his interest was nevertheless keenly aroused. For he saw the man, as his gaze fell on himself and Merriman, give a sudden start, and then flash a quick, questioning glance at Mr. Coburn. The action was momentary, but it was enough to bring back with a rush all Hilliard's suspicions. Surely, he thought, there must be something if the sight of a stranger upsets all these people in this way.

But he had not time to ponder the problem. The captain instantly recovered himself, pulled off his cap to Miss Coburn and shook hands all round, Mr. Coburn introducing the visitors.

"Good trip, captain?" the manager went on. "You're ahead of schedule."

"Not so bad," the newcomer admitted in a voice and manner singularly cultivated for a man in his position. "We had a good wind behind us most of the way."

They chatted for a few moments, then started on their tour of inspection. Though Hilliard was once again keenly on the alert, the examination, so far as he could see, left nothing to be desired. They visited every part of the vessel, from the forecastle storerooms to the tunnel of the screw shaft, and from the chart-house to the bottom of the hold, and every question either of the friends asked was replied to fully and without hesitation.

That evening, like the preceding, they passed with the Coburns. The captain and the engineer—a short, thick-set man named Bulla—strolled up with them and remained for dinner, but left shortly afterwards on the plea of matters to attend to on board. The friends stayed on, playing bridge, and it was late when they said good-night and set out to walk back to the launch.

During the intervals of play Hilliard's mind had been busy with the mystery which he believed existed in connection with the syndicate, and he had decided that to try to satisfy his curiosity he would go down to the wharf that night and see if any INTERESTING operations went on under cover of darkness. The idea of a midnight loading of contraband no longer appealed to his imagination, but vaguely he wished to make sure that no secret activities were in progress.

He was at least certain that none had taken place up to the present—that Mr. Coburn was personally concerned in, at all events. From the moment they had first sighted the ship until they had left the manager's house at the conclusion of the game of bridge, not five minutes ago, he had been in Mr. Coburn's company. Next day it was understood they were to meet again, so that if the manager wished to carry out any secret operations they could only be done during the night.

Accordingly when they reached the launch he turned to Merriman.

"You go ahead, old man. I'm going to have a look round before turning in. Don't wait up for me. Put out the light when you've done with it and leave the companion unlatched so that I can follow you in."

Merriman grunted disapprovingly, but offered no further objection. He clambered on board the launch and disappeared below, while Hilliard, remaining in the collapsible boat, began to row silently up-stream towards the wharf.

The night was dark and still, but warm. The moon had not risen, and the sky was overcast, blotting out even the small light of the stars. There was a faint whisper of air currents among the trees, and the subdued murmur of the moving mass of water was punctuated by tiny splashes and gurgles as little eddies formed round the stem of the boat or wavelets broke against the banks. Hilliard's eyes had by this time become accustomed to the gloom, and he could dimly distinguish the serrated line of the trees against the sky on either side of him, and later, the banks of the clearing, with the faint, ghostly radiance from the surface of the water.

He pulled on with swift, silent strokes, and presently the dark mass of the Girondin loomed in sight. The ship, longer than the wharf, projected for several feet above and below it. Hilliard turned his boat inshore with the object of passing between the hull and the bank and so reaching the landing steps. But as he rounded the vessel's stern he saw that her starboard side was lighted up, and he ceased rowing, sitting motionless and silently holding water, till the boat began to drift back into the obscurity down-stream. The wharf was above the level of his head, and he could only see, appearing over its edge, the tops of the piles of pit-props. These, as well as the end of the ship's navigating bridge and the gangway, were illuminated by, he imagined, a lamp on the side of one of the deckhouses. But everything was very still, and the place seemed deserted.

Hilliard's intention had been to land on the wharf and, crouching behind the props, await events. But now he doubted if he could reach his hiding place without coming within the radius of the lamp and so exposing himself to the view of anyone who might be on the watch on board. He recollected that the port or river side of the ship was in darkness, and he thought it might therefore be better if he could get directly aboard there from the boat.

Having removed his shoes he rowed gently round the stern and examined the side for a possible way up. The ship being light forward was heavily down in the stern, and he found the lower deck was not more than six or seven feet above water level. It occurred to him that if he could get hold of the mooring rope pawls he might be able to climb aboard. But this after a number of trials he found impossible, as in the absence of someone at the oars to steady the boat, the latter always drifted away from the hull before he could grasp what he wanted.

He decided he must risk passing through the lighted area, and, having for the third time rowed round the stern, he brought the boat up as close to the hull as possible until he reached the wharf. Then passing in between the two rows of piles and feeling his way in the dark, he made the painter fast to a diagonal, so that the boat would lie hidden should anyone examine the steps with a light. The hull lay touching the vertical piles, and Hilliard, edging along a waling to the front of the wharf, felt with his foot through the darkness for the stern belting. The tide was low and he found this was not more than a foot above the timber on which he stood. He could now see the deck light, an electric bulb on the side of the captain's cabin, and it showed him the top of the taffrail some little distance above the level of his eyes. Taking his courage in both hands and stepping upon the belting, he succeeded in grasping the taffrail. In a moment he was over it and on deck, and in another moment he had slipped round the deckhouse and out of the light of the lamp. There he stopped, listening for an alarm, but the silence remained unbroken, and he believed he had been unobserved.

He recalled the construction of the ship. The lower deck, on which he was standing, ran across the stern and formed a narrow passage some forty feet long at each side of the central cabin. This cabin contained the galley and mess room as well as the first officer's quarters. Bulla's stateroom, Hilliard remembered, was down below beside the engine-room.

From the lower deck two ladders led to the bridge deck at the forward end of which was situated the captain's stateroom. Aft of this building most of the remaining bridge deck was taken up by two lifeboats, canvas-covered and housed in chocks. On the top of the captain's cabin was the bridge and chart-house, reached by two ladders which passed up at either side of the cabin.

Hilliard, reconnoitering, crept round to the port side of the ship. The lower deck was in complete darkness, and he passed the range of cabins and silently ascended the steps to the deck above. Here also it was dark, but a faint light shone from the window of the captain's cabin. Stealthily Hilliard tiptoed to the porthole. The glass was hooked back, but a curtain hung across the opening. Fortunately, it was not drawn quite tight to one side, and he found that by leaning up against the bridge ladder he could see into the interior. A glance showed him that the room was empty.

As he paused irresolutely, wondering what he should do next, he heard a door open. There was a step on the deck below, and the door slammed sharply. Someone was coming to the ladder at the top of which he stood.

Like a shadow Hilliard slipped aft, and, as he heard the unknown ascending the steps, he looked round for cover. The starboard boat and a narrow strip of deck were lighted up, but the port boat was in shadow. He could distinguish it merely as a dark blot on the sky. Recognizing that he must be hidden should the port deck light be turned on, he reached the boat, felt his way round the stern, and, crouching down, crept as far underneath it as he could. There he remained motionless.

The newcomer began slowly to pace the deck, and the aroma of a good cigar floated in the still air. Up and down he walked with leisurely, unhurried footsteps. He kept to the dark side of the ship, and Hilliard, though he caught glimpses of the red point of the cigar each time the other reached the stern, could not tell who he was.

Presently other footsteps announced the approach of a second individual, and in a moment Hilliard heard the captain's voice.

"Where are you, Bulla?"

"Here," came in the engineer's voice from the first-comer. The captain approached and the two men fell to pacing up and down, talking in low tones. Hilliard could catch the words when the speakers were near the stern, but lost them when they went forward to the break of the poop.

"Confound that man Coburn," he heard Captain Beamish mutter. "What on earth is keeping him all this time?"

"The young visitors, doubtless," rumbled Bulla with a fat chuckle, "our friends of the evening."

"Yes, confound them, too," growled Beamish, who seemed to be in an unenviable frame of mind. "Damned nuisance their coming round. I should like to know what they are after."

"Nothing particular, I should fancy. Probably out doing some kind of a holiday."

They passed round the deckhouse and Hilliard could not hear the reply. When they returned Captain Beamish was speaking.

"—thinks it would about double our profits," Hilliard heard him say. "He suggests a second depot on the other side, say at Swansea. That would look all right on account of the South Wales coalfields."

"But we're getting all we can out of the old hooker as it is," Bulla objected. "I don't see how she could do another trip."

"Archer suggests a second boat."

"Oh." The engineer paused, then went on: "But that's no new SUGGESTION. That was proposed before ever the thing was started."

"I know, but the circumstances have changed. Now we should—"

Again they passed out of earshot, and Hilliard took the opportunity to stretch his somewhat cramped limbs. He was considerably interested by what he had heard. The phrase Captain Beamish had used in reference to the proposed depot at Swansea—"it would look all right on account of the coalfields"—was suggestive. Surely that was meaningless unless there was some secret activity—unless the pit-prop trade was only a blind to cover some more lucrative and probably more sinister undertaking? At first sight it seemed so, but he had not time to think it out then. The men were returning.

Bulla was speaking this time, and Hilliard soon found he was telling a somewhat improper story. As the two men disappeared round the deckhouse he heard their hoarse laughter ring out. Then the captain cried: "That you, Coburn?" The murmur of voices grew louder and more confused and immediately sank. A door opened, then closed, and once more silence reigned.

To Hilliard it seemed that here was a chance which he must not miss. Coming out from his hiding place, he crept stealthily along the deck in the hope that he might find out where the men had gone, and learn something from their conversation.

The captain's cabin was the probable meeting place, and Hilliard slipped silently back to the window through which he had glanced before. As he approached he heard a murmur of voices, and he cautiously leaned back against the bridge ladder and peeped in round the partly open curtain.

Three of the four seats the room contained were now occupied. The captain, engineer, and Mr. Coburn sat round the central table, which bore a bottle of whisky, a soda siphon and glasses, as well as a box of cigars. The men seemed preoccupied and a little anxious. The captain was speaking.

"And have you found out anything about them?" he asked Mr. Coburn.

"Only what I have been able to pick up from their own conversation," the manager answered. "I wrote Morton asking him to make inquiries about them, but of course there hasn't been time yet for a reply. From their own showing one of them is Seymour Merriman, junior partner of Edwards & Merriman, Gracechurch Street, Wine Merchants. That's the dark, square-faced one—the one who was here before. The other is a man called Hilliard. He is a clever fellow, and holds a good position in the Customs Department. He has had this launch for some years, and apparently has done the same kind of trip through the Continental rivers on previous holidays. But I could not find out whether Merriman had ever accompanied him before."

"But you don't think they smell a rat?"

"I don't think so," he said slowly, "but I'm not at all sure. Merriman, we believe, noticed the number plate that day. I told you, you remember. Henri is sure that he did, and Madeleine thinks so too. It's just a little queer his coming back. But I'll swear they've seen nothing suspicious this time."

"You can't yourself account for his coming back?"

Again Mr. Coburn hesitated.

"Not with any certainty," he said at last, then with a grimace he continued: "But I'm a little afraid that it's perhaps Madeleine."

Bulla, the engineer, made a sudden gesture.

"I thought so," he exclaimed. "Even in the little I saw of them this evening I thought there was something in the wind. I guess that accounts for the whole thing. What do you say, skipper?"

The big man nodded.

"I should think so," he admitted, with a look of relief. "I think it's a mare's nest, Coburn. I don't believe we need worry."

"I'm not so sure," Coburn answered slowly. "I don't think we need worry about Merriman, but I'm hanged if I know what to think about Hilliard. He's pretty observant, and there's not much about this place that he hasn't seen at one time or another."

"All the better for us, isn't it?" Bulla queried.

"So far as it goes, yes," the manager agreed, "and I've stuffed him with yarns about costs and about giving up the props and going in for paving blocks and so on which I think he swallowed. But why should he want to know what we are doing? What possible interest can the place have for him—unless he suspects?"

"They haven't done anything suspicious themselves?"

"Not that I have seen."

"Never caught them trying to pump any of the men?"

"Never."

Captain Beamish moved impatiently.

"I don't think we need worry," he repeated with a trace of aggression in his manner. "Let's get on to business. Have you heard from Archer?"

Mr. Coburn drew a paper from his pocket, while Hilliard instinctively bent forward, believing he was at last about to learn something which would throw a light on these mysterious happenings. But alas for him! Just as the manager began to speak he heard steps on the gangway which passed on board and a man began to climb the starboard ladder to the upper deck.

Hilliard's first thought was to return to his hiding place under the boat, but he could not bring himself to go so far away from the center of interest, and before he had consciously thought out the situation he found himself creeping silently up the ladder to the bridge. There he believed he would be safe from observation while remaining within earshot of the cabin, and if anyone followed him up the ladder he could creep round on the roof of the cabin to the back of the chart-house, out of sight.

The newcomer tapped at the captain's door and, after a shout of "Come in," opened it. There was a moment's silence, then Coburn's voice said:

"We were just talking of you, Henri. The skipper wants to know—" and the door closed.

Hilliard was not long in slipping back to his former position at the porthole.

"By Jove!" Bulla was saying. "And to think that two years ago I was working a little coaster at twenty quid a month! And you, Coburn; two years ago you weren't much better fixed, if as well, eh?"

Coburn ignored the question.

"It's good, but it's not good enough," he declared. "This thing can't run for ever. If we go on too long somebody will tumble to it. What we want is to try to get our piles made and close it down before anything happens. We ought to have that other ship running. We could double our income with another ship and another depot. And Swansea seems to me the place."

"Bulla and I were just talking of that before you came aboard," the captain answered. "You know we have considered that again and again, and we have always come to the conclusion that we are pushing the thing strongly enough."

"Our organization has improved since then. We can do more now with less risk. It ought to be reconsidered. Will you go into the thing, skipper?"

"Certainly. I'll bring it before our next meeting. But I won't promise to vote for it. In our business it's not difficult to kill the goose, etcetera."

The talk drifted to other matters, while Hilliard, thrilled to the marrow, remained crouching motionless beneath the porthole, concentrating all his attention on the conversation in the hope of catching some word or phrase which might throw further light on the mysterious enterprise under discussion. While the affair itself was being spoken of he had almost ceased to be aware of his surroundings, so eagerly had he listened to what was being said, but now that the talk had turned to more ordinary subjects he began more or less subconsciously to take stock of his own position.

He realized in the first place that he was in very real danger. A quick movement either of the men in the cabin or of some member of the crew might lead to his discovery, and he had the uncomfortable feeling that he might pay the forfeit for his curiosity with his life. He could imagine the manner in which the "accident" would be staged. Doubtless his body, showing all the appearance of death from drowning, would be found in the river with alongside it the upturned boat as evidence of the cause of the disaster.

And if he should die, his secret would die with him. Should he not then be content with what he had learned and clear out while he could, so as to ensure his knowledge being preserved? He felt that he ought, and yet the desire to remain in the hope of doing still better was overpowering. But as he hesitated the power of choice was taken away. The men in the cabin were making a move. Coburn finished his whisky, and he and Henri rose to their feet.

"Well," the former said, "There's one o'clock. We must be off."

The others stood up also, and at the same moment Hilliard crept once more up the ladder to the bridge and crouched down in the shadow of the chart-house. Hardly was he there when the men came out of the cabin to the deck beneath the bridge, then with a brief exchange of "Good-nights," Coburn and the lorry driver passed down the ladder, crossed the gangway and disappeared behind a stack of pit-props on the wharf. Bulla with a grunted "'Night" descended the port steps and Hilliard heard the door leading below open and shut; the starboard deck lamp snapped off, and finally the captain's door shut and a key turned in the lock. Some fifteen minutes later the faint light from the porthole vanished and all was dark and silent.

But for more than an hour Hilliard remained crouching motionless on the bridge, fearing lest some sound that he might make in his descent should betray him if the captain should still be awake. Then, a faint light from the rising moon appearing towards the east, he crept from his perch, and crossing the gangway, reached the wharf and presently his boat.

Ten minutes later he was on board the launch.



CHAPTER 6. A CHANGE OF VENUE

Still making as little noise as possible, Hilliard descended to the cabin and turned in. Merriman was asleep, and the quiet movement of the other did not awaken him.

But Hilliard was in no frame of mind for repose. He was too much thrilled by the adventure through which he had passed, and the discovery which he had made. He therefore put away the idea of sleep, and instead gave himself up to consideration of the situation.

He began by trying to marshal the facts he had already learned. In the first place, there was the great outstanding point that his suspicions were well founded, that some secret and mysterious business was being carried on by this syndicate. Not only, therefore, was he justified in all he had done up to the present, but it was clear he could not leave the matter where it stood. Either he must continue his investigations further, or he must report to headquarters what he had overheard.

Next, it seemed likely that the syndicate consisted of at least six persons; Captain Beamish (probably from his personality the leader), Bulla, Coburn, Henri, and the two men to whom reference had been made, Archer, who had suggested forming the depot at Swansea, and Morton, who had been asked to make inquiries as to himself and Merriman. Madeleine Coburn's name had also been mentioned, and Hilliard wondered whether she could be a member. Like his companion he could not believe that she would be willingly involved, but on the other hand Coburn had stated that she had reported her suspicion that Merriman had noticed the changed number plate. Hilliard could come to no conclusion about her, but it remained clear that there were certainly four members, and probably six or more.

But if so, it followed that the operations must be on a fairly large scale. Educated men did not take up a risky and presumably illegal enterprise unless the prize was worth having. It was unlikely that 1,000 pounds a year would compensate any one of them for the risk. But that would mean a profit of from 4,000 to 6,000 pounds a year. Hilliard realized that he was here on shaky ground, though the balance of probability was in his favor.

It also seemed certain that the whole pit-prop business was a sham, a mere blind to cover those other operations from which the money came. But when Hilliard came to ask himself what those operations were, he found himself up against a more difficult proposition.

His original brandy smuggling idea recurred to him with renewed force, and as he pondered it he saw that there really was something to be said for it. Three distinct considerations were consistent with the theory.

There was first of all the size of the fraud. A theft of 4,000 to 6,000 or more a year implied as victim a large corporation. The sum would be too big a proportion of the income of a moderate-sized firm for the matter to remain undiscovered, and, other things being equal, the larger the corporation the more difficult to locate the leakage.

But what larger corporation was there than a nation, and what so easy to defraud as a government? And how could a government be more easily defrauded than by smuggling? Here again Hilliard recognized he was only theorizing; still the point had a certain weight.

The second consideration was also inconclusive. It was that all the people who, he had so far learned, were involved were engaged in transport operations. The ostensible trade also, the blind under which the thing was worked, was a transport trade. If brandy smuggling were in progress something of precisely this kind would have to be devised. In fact anything more suitable than the pit-prop business would be hard to discover.

The third point he had thought of before. If brandy were to be smuggled, no better locality could have been found for the venture than this country round about Bordeaux. As one of the staple products of the district, brandy could be obtained here, possibly more easily than anywhere else.

The converse argument was equally inconclusive. What hypothesis other than that of brandy smuggling could meet the facts? Hilliard could not think of any, but he recognized that his failure did not prove that none existed.

On the other hand, in spite of these considerations, he had to admit that he had seen nothing which in the slightest degree supported the theory, nor had he heard anything which could not equally well have referred to something else.

But whatever their objective, he felt sure that the members of the syndicate were desperate men. They were evidently too far committed to hesitate over fresh crime to keep their secret. If he wished to pursue his investigations, it was up to him to do so without arousing their suspicions.

As he pondered over the problem of how this was to be done he became more and more conscious of its difficulty. Such an inquiry to a trained detective could not be easy, but to him, an amateur at the game, it seemed well-nigh impossible. And particularly he found himself handicapped by the intimate terms with the Coburns on which he and Merriman found themselves. For instance, that very morning an excursion had been arranged to an old chateau near Bordeaux. How could he refuse to go? And if he went how could he watch the loading of the Girondin?

He had suspected before that the Coburns' hospitality was due to something other than friendliness, and now he was sure of it. No longer had he any doubt that the object was to get him out of the way, to create that very obstacle to investigation which it had created. And here again Miss Coburn had undoubtedly lent herself to the plot.

He was not long in coming to the conclusion that the sooner he and Merriman took leave of the Coburns the better. Besides this question of handicap, he was afraid with so astute a man as Coburn he would sooner or later give himself away.

The thought led to another. Would it not be wise to keep Merriman in ignorance of what he had learned at least for the present? Merriman was an open, straightforward chap, transparently honest in all his dealings. Could he dissemble sufficiently to hide his knowledge from his hosts? In particular could he deceive Madeleine? Hilliard doubted it. He felt that under the special circumstances his friend's discretion could not be relied on. At all events Merriman's appearance of ignorance would be more convincing if it were genuine.

On the whole, Hilliard decided, it would be better not to tell him. Let them once get away from the neighborhood, and he could share his discoveries and they could together decide what was to be done. But first, to get away.

Accordingly next morning he broached the subject. He had expected his friend would strenuously oppose any plan involving separation from Madeleine Coburn, but to his relief Merriman immediately agreed with him.

"I've been thinking we ought to clear out too," he declared ungrammatically. "It's not good enough to be accepting continuous hospitality which you can't return."

Hilliard assented carelessly, remarked that if they started the following morning they could reach the Riviera by the following Friday, and let it go at that. He did not refer again to the subject until they reached the Coburns' door, when he asked quickly: "By the way, will you tell them we're leaving tomorrow or shall I?"

"I will," said Merriman, to his relief.

The Girondin was loading props as they set out in the Ford car, and the work was still in progress on their return in the late afternoon. Mr. Coburn had excused himself from joining the party on the ground of business, but Captain Beamish had taken his place, and had proved himself a surprisingly entertaining companion. At the old chateau they had a pleasant alfresco lunch, after which Captain Beamish took a number of photographs of the party with his pocket Kodak.

Merriman's announcement of his and Hilliard's impending departure had been met with a chorus of regrets, but though these sounded hearty enough, Hilliard noticed that no definite invitation to stay longer was given.

The friends dined with the Coburns for the last time that evening. Mr. Coburn was a little late for the meal, saying he had waited on the wharf to see the loading completed, and that all the cargo was now aboard, and that the Girondin would drop down to sea on the flood tide in the early morning.

"We shall have her company so far," Hilliard remarked. "We must start early, too, so as to make Bordeaux before dark."

When the time came to say good-bye, Mr. Coburn and his daughter went down to the launch with their departing visitors. Hilliard was careful to monopolize the manager's attention, so as to give Merriman his innings with the girl. His friend did not tell him what passed between them, but the parting was evidently affecting, as Merriman retired to his locker practically in silence.

Five o'clock next morning saw the friends astir, and their first sight on reaching the deck was the Girondin coming down-stream. They exchanged hand waves with Captain Beamish on the bridge, then, swinging their own craft, followed in the wake of the other. A couple of hours later they were at sea.

Once again they were lucky in their weather. A sun of molten glory poured down from the clearest of blue skies, burnishing a track of intolerable brilliance across the water. Hardly a ripple appeared on the smooth surface, though they rose and fell gently to the flat ocean swell. They were running up the coast about four miles out, and except for the Girondin, now almost hull down to the north-west, they had the sea to themselves. It was hot enough to make the breeze caused by the launch's progress pleasantly cool, and both men lay smoking on the deck, lazily watching the water and enjoying the easy motion. Hilliard had made the wheel fast, and reached up every now and then to give it a slight turn.

"Jolly, I call this," he exclaimed, as he lay down again after one of these interruptions. "Jolly sun, jolly sea, jolly everything, isn't it?"

"Rather. Even a landlubber like me can appreciate it. But you don't often have it like this, I bet."

"Oh, I don't know," Hilliard answered absently, and then, swinging round and facing his friend, he went on:

"I say, Merriman, I've something to tell you that will interest you, but I'm afraid it won't please you."

Merriman laughed contentedly.

"You arouse my curiosity anyway," he declared. "Get on and let's hear it."

Hilliard answered quietly, but he felt excitement arising in him as he thought of the disclosure he was about to make.

"First of all," he began, speaking more and more earnestly as he proceeded, "I have to make you an apology. I quite deliberately deceived you up at the clearing, or rather I withheld from you knowledge that I ought to have shared. I had a reason for it, but I don't know if you'll agree that it was sufficient."

"Tell me."

"You remember the night before last when I rowed up to the wharf after we had left the Coburns? You thought my suspicions were absurd or worse. Well, they weren't. I made a discovery."

Merriman sat up eagerly, and listened intently as the other recounted his adventure aboard the Girondin. Hilliard kept nothing back; even the reference to Madeleine he repeated as nearly word for word as possible, finally giving a bowdlerized version of his reasons for keeping his discoveries to himself while they remained in the neighborhood.

Merriman received the news with a dismay approaching positive horror. He had but one thought—Madeleine. How did the situation affect her? Was she in trouble? In danger? Was she so entangled that she could not get out? Never for a moment did it enter his head that she could be willingly involved.

"My goodness! Hilliard," he cried hoarsely, "whatever does it all mean? Surely it can't be criminal? They,"—he hesitated slightly, and Hilliard read in a different pronoun—"they never would join in such a thing."

Hilliard took the bull by the horns.

"That Miss Coburn would take part in anything shady I don't for a moment believe," he declared, "but I'm afraid I wouldn't be so sure of her father."

Merriman shook his head and groaned.

"I know you're right," he admitted to the other's amazement. "I saw—I didn't mean to tell you, but now I may as well. That first evening, when we went up to call, you probably don't remember, but after he had learned who we were he turned round to pull up a chair. He looked at you; I saw his face in a mirror. Hilliard, it was the face of a—I was going to say, a devil—with hate and fear. But the look passed instantly. When he turned round he was smiling. It was so quick I half thought I was mistaken. But I know I wasn't."

"I saw fear on his face when he recognized you that same evening," Hilliard replied. "We needn't blink at it, Merriman. Whether willingly or unwillingly, Mr. Coburn's in the thing. That's as certain as that we're here."

"But what is it? Have you any theory?"

"No, not really. There was that one of brandy smuggling that I mentioned before. I suggest it because I can suggest nothing else, but I admit I saw no evidence of it."

Merriman was silent for several minutes as the boat slid over the smooth water. Then with a change of manner he turned once more to his friend.

"I suppose we couldn't leave it alone? Is it our business after all?"

"If we don't act we become accessories, and besides we leave that girl to fight her own battles."

Merriman clenched his fists and once more silence reigned. Presently he spoke again:

"You had something in your mind?"

"I think we must do one of two things. Either continue our investigations until we learn what is going on, or else clear out and tell the police what we have learned."

Merriman made a gesture of dissent.

"Not that, not that," he cried. "Anything rather than the police."

Hilliard gazed vacantly on the long line of the coast.

"Look here, old man," he said, "Wouldn't it be better if we discussed this thing quite directly? Don't think I mean to be impertinent—God knows I don't—but am I not right in thinking you want to save Miss Coburn all annoyance, and her father also, for her sake?"

"We needn't talk about it again," Merriman said in a hard voice, looking intently at the stem of the mast, "but if it's necessary to make things clear, I want to marry her if she'll have me."

"I thought so, old man, and I can only say—the best of luck! As you say, then, we mustn't call in the police, and as we can't leave the thing, we must go on with our own inquiry. I would suggest that if we find out their scheme is something illegal, we see Mr. Coburn and give him the chance to get out before we lodge our information."

"I suppose that is the only way," Merriman said doubtfully. After a pause Hilliard went on:

"I'm not very clear, but I'm inclined to think we can do no more good here at present. I think we should try the other end."

"The other end?"

"Yes, the unloading of the ship and the disposal of the pit-props. You see, the first thing we're up against is that these people are anything but fools, and the second is that they already suspect us and will keep a watch on us. A hundred to one they make inquiries and see that we really do go through the Canal du Midi to the Riviera. We can't hang about Bordeaux without their knowing it."

"That's true."

"Of course," Hilliard went on, "we can see now we made a frightful mess of things by calling on the Coburns or letting Mr. Coburn know we were about, but at the time it seemed the wisest thing."

"It was the only thing," Merriman asserted positively. "We didn't know then there was anything wrong, and besides, how could we have hidden the launch?"

"Well, it's done anyway. We needn't worry about it now, except that it seems to me that for the same reason the launch has served its purpose. We can't use it here because the people at the clearing know it, and we can't use it at the unloading end, for all on board the Girondin would recognize it directly they saw it."

Merriman nodded without speaking and Hilliard continued:

"I think, therefore, that we should leave the launch at Bordeaux tonight and go back to London overland. I shall write Mr. Coburn saying we have found Poste Restante letters recalling us. You can enclose a note to Miss Coburn if you like. When we get to town we can apply at the Inquiry Office at Lloyd's to find out where the Girondin calls in England. Then let us go there and make inquiries. The launch can be worked back to England some other time. How does that strike you?"

"Seems all right. But I should leave the launch at Bordeaux. We may have to come back, and it would furnish us with an excuse for our presence if we were seen."

Hilliard gave a little sigh of relief. Merriman's reply took a weight off his mind, not because of the value of the SUGGESTION—though in its way it was quite useful—but because of its indication of Merriman's frame of mind. He had feared that because of Miss Coburn's connection with the affair he would lose his friend's help, even that they might quarrel. And now he saw these fears were groundless. Thankfully he recognized that they would co-operate as they had originally intended.

"Jolly good notion, that," he answered cordially.

"I confess," Merriman went on slowly, "that I should have liked to stay in the neighborhood and see if we couldn't find out something more about the lorry numbers. It may be a trivial point, but it's the only direct and definite thing we know of. All the rest are hints or suspicions or probabilities. But here we have a bit of mystery, tangible, in our hands, as it were. Why were those number plates changed? It seems to me a good point of attack."

"I thought of that, too, and I agree with every word you say," Hilliard replied eagerly, "but there is the question of our being suspects. I believe we shall be watched out of the place, and I feel sure our only chance of learning anything is to satisfy them of our bona fides."

Merriman agreed, and they continued discussing the matter in detail, at last deciding to adopt Hilliard's SUGGESTION and set to work on the English end of the mysterious traffic.

About two that afternoon they swung round the Pointe de Grave into the estuary of the Gironde. The tide, which was then flowing, turned when they were some two-thirds of the way up, and it was well on to seven o'clock when they made fast to the same decaying wharf from which they had set out. Hilliard saw the owner, and arranged with him to let the launch lie at one of his moorings until she should be required. Then the friends went up town, got some dinner, wrote their letters, and took the night train for Paris. Next evening they were in London.

"I say," Hilliard remarked when later on that same evening they sat in his rooms discussing their plans, "I believe we can find out about the Girondin now. My neighbor on the next landing above is a shipping man. He might have a copy of Lloyd's Register. I shall go and ask him."

In a few moments he returned with a bulky volume. "One of the wonders of the world, this, I always think," he said, as he began to turn over the pages. "It gives, or is supposed to give, information about everything over a hundred tons that floats anywhere over the entire globe. It'll give the Girondin anyway." He ran his finger down the columns. "Ah! what's this? Motor ship Girondin, 350 tons, built and so on. 'The Landes Pit-Prop Syndicate, Ferriby, Hull.' Hull, my son. There we are."

"Hull! I know Hull," Merriman remarked laconically. "At least, I was there once."

"We shall know it a jolly sight better than that before we're through, it seems to me," his friend replied. "Let's hope so, anyway."

"What's the plan, then? I'm on, provided I have a good sleep at home tonight first."

"Same here," Hilliard agreed as he filled his pipe. "I suppose Hull by an early train tomorrow is the scheme."

Merriman borrowed his friend's pouch and refilled his pipe in his turn.

"You think so?" he said slowly. "Well, I'm not so sure. Seems to me we can very easily dish ourselves if we're not careful."

"How so?"

"We agreed these folk were wide-awake and suspicious of us. Very well. Directly our visit to them is over, we change our plans and leave Bordeaux. Will it not strike them that our interest in the trip was only on their account?"

"I don't see it. We gave a good reason for leaving."

"Quite; that's what I'm coming to. We told them you were recalled to your office. But what about that man Morton, that was to spy on us before? What's to prevent them asking him if you really have returned?"

Hilliard sat up sharply.

"By Jove!" he cried. "I never thought of that."

"And there's another thing," Merriman went on. "We turn up at Hull, find the syndicate's depot and hang about, the fellow in charge there sees us. Well, that's all right if he hasn't had a letter from France describing us and enclosing a copy of that group that Captain Beamish took at the chateau."

Hilliard whistled.

"Lord! It's not going to be so simple as it looks, is it?"

"It isn't. And what's more, we can't afford to make any mistakes. It's too dangerous."

Hilliard got up and began to pace the room.

"I don't care," he declared savagely. "I'm going through with it now no matter what happens."

"Oh, so am I, for the matter of that. All I say is we shall have to show a bit more intelligence this time."

For an hour more they discussed the matter, and at last decided on a plan. On the following morning Hilliard was to go to his office, see his chief and ask for an extension of leave, then hang about and interview as many of his colleagues as possible, telling them he had been recalled, but was not now required. His chief was not very approachable, and Hilliard felt sure the subject would not be broached to him. In the evening they would go down to Hull.

This program they would have carried out, but for an unforeseen event. While Hilliard was visiting his office Merriman took the opportunity to call at his, and there learned that Edwards, his partner, had been taken ill the morning before. It appeared there was nothing seriously wrong, and Edwards expected to be back at work in three or four days, but until his return Merriman was required, and he had reluctantly to telephone the news to Hilliard. But no part of their combined holiday was lost. Hilliard by a stroke of unexpected good fortune was able to spend the same time at work, and postpone the remainder of his leave until Merriman was free. Thus it came to pass that it was not until six days later than they had intended that the two friends packed their bags for Hull.

They left King's Cross by the 5.40 p.m. train, reaching their destination a little before eleven. There they took rooms at the George, a quiet hotel in Baker Street, close to the Paragon Station.



CHAPTER 7. THE FERRIBY DEPOT

The two friends, eager and excited by their adventure, were early astir next morning, and after breakfast Hilliard went out and bought the best map of the city and district he could find.

"Why, Ferriby's not in the town at all," he exclaimed after he had studied it for some moments. "It's up the river—must be seven or eight miles up by the look of it; the North-Eastern runs through it and there's a station. We'd better go out there and prospect."

Merriman agreed, they called for a timetable, found there was a train at 10.35, and going down to Paragon Station, got on board.

After clearing the suburbs the line came down close to the river, and the two friends kept a good look-out for the depot. About four and a half miles out they stopped at a station called Hassle, then a couple of miles farther their perseverance was rewarded and they saw a small pier and shed, the latter bearing in large letters on its roof the name of the syndicate. Another mile and a half brought them to Ferriby, where they alighted.

"Now what about walking back to Hassle," Hilliard suggested, "and seeing what we can see?"

They followed the station approach road inland until they reached the main thoroughfare, along which they turned eastwards in the direction of Hull. In a few minutes they came in sight of the depot, half a mile off across the fields. A lane led towards it, and this they followed until it reached the railway.

River Humber

There it turned in the direction of Hull and ran parallel to the line for a short distance, doubling back, as they learned afterwards, until it reached the main road half-way to Hassle. The railway tracks were on a low bank, and the men could just see across them to the syndicate's headquarters.

The view was not very good, but so far as they could make out, the depot was a replica of that in the Landes clearing. A timber wharf jutted out into the stream, apparently of the same size and construction as that on the River Lesque. Behind it was the same kind of galvanized iron shed, but this one, besides having windows in the gables, seemed the smaller of the two. Its back was only about a hundred feet from the railway, and the space between was taken up by a yard surrounded by a high galvanized iron fence, above which appeared the tops of many stacks of pit-props. Into the yard ran a siding from the railway. From a door in the fence a path led across the line to a wicket in the hedge of the lane, beside which stood a "Beware of the Trains" notice. There was no sign of activity about the place, and the gates through which the siding entered the enclosure were shut.

Hilliard stopped and stood looking over.

"How the mischief are we to get near that place without being seen?" he questioned. "It's like a German pill-box. There's no cover anywhere about."

It was true. The country immediately surrounding the depot was singularly bare. It was flat except for the low bank, four or five feet high, on which lay the railway tracks. There were clumps of trees farther inland, but none along the shore, and the nearest building, a large block like a factory with beside it a cottage, was at least three hundred yards away in the Hull direction.

"Seems an element of design in that, eh, Hilliard?" Merriman remarked as they turned to continue their walk. "Considering the populous country we're in, you could hardly find a more isolated place."

Hilliard nodded as they turned away.

"I've just been thinking that. They could carry on any tricks they liked there and no one would be a bit the wiser."

They moved on towards the factory-like building. It was on the inland side of the railway, and the lane swung away from the line and passed what was evidently its frontage. A siding ran into its rear, and there were connections across the main lines and a signal cabin in the distance. A few yards on the nearer side stood the cottage, which they now saw was empty and dilapidated.

"I say, Hilliard, look there!" cried Merriman suddenly.

They had passed along the lane until the facade of the building had come into view and they were able to read its signboard: "Ackroyd & Bolt, Licensed Rectifiers."

"I thought it looked like a distillery," continued Merriman in considerable excitement. "By Jove! Hilliard, that's a find and no mistake! Pretty suggestive, that, isn't it?"

Hilliard was not so enthusiastic.

"I'm not so sure," he said slowly. "You mean that it supports my brandy smuggling theory? Just how?"

"Well, what do you think yourself? We suspect brandy smuggling, and here we find at the import end of the concern the nearest building in an isolated region is a distillery—a rectifying house, mind you! Isn't that a matter of design too? How better could they dispose of their stuff than by dumping it on to rectifiers?"

"You distinguish between distillers and rectifiers?"

"Certainly; there's less check on rectifiers. Am I not right in saying that while the regulations for the measurement of spirit actually produced from the stills are so thorough as to make fraud almost impossible, rectifiers, because they don't themselves produce spirit, but merely refine what other firms have produced, are not so strictly looked after? Rectifiers would surely find smuggled stuff easier to dispose of than distillers."

Hilliard shook his head.

"Perhaps so, theoretically," he admitted, "but in practice there's nothing in it. Neither could work a fraud like that, for both are watched far too closely by our people. I'm afraid I don't see that this place being here helps us. Surely it's reasonable to suppose that the same cause brought Messrs. Ackroyd & Bolt that attracted the syndicate? Just that it's a good site. Where in the district could you get a better? Cheap ground and plenty of it, and steamer and rail connections."

"It's a coincidence anyway."

"I don't see it. In any case unless we can prove that the ship brings brandy the question doesn't arise."

Merriman shrugged his shoulders good-humoredly.

"That's a blow," he remarked. "And I was so sure I had got hold of something good! But it just leads us back to the question that somehow or other we must inspect that depot, and if we find nothing we must watch the Girondin unloading. If we can only get near enough it would be impossible for them to discharge anything in bulk without our seeing it."

Hilliard murmured an agreement, and the two men strolled on in silence, the thoughts of each busy with the problem Merriman had set. Both were realizing that detective work was a very much more difficult business than they had imagined. Had not each had a strong motive for continuing the investigation, it is possible they might have grown fainthearted. But Hilliard had before him the vision of the kudos which would accrue to him if he could unmask a far-reaching conspiracy, while to Merriman the freeing of Madeleine Coburn from the toils in which she seemed to have been enmeshed had become of more importance than anything else in the world.

The two friends had already left the distillery half a mile behind, when Hilliard stopped and looked at his watch.

"Ten minutes to twelve," he announced. "As we have nothing to do let's go back and watch that place. Something may happen during the afternoon, and if not we'll look out for the workmen leaving and see if we can pick up something from them."

They retraced their steps past the distillery and depot, then creeping into a little wood, sat down on a bank within sight of the enclosure and waited.

The day was hot and somewhat enervating, and both enjoyed the relaxation in the cool shade. They sat for the most part in silence, smoking steadily, and turning over in their minds the problems with which they were faced. Before them the country sloped gently down to the railway bank, along the top of which the polished edges of the rails gleamed in the midday sun. Beyond was the wide expanse of the river, with a dazzling track of shimmering gold stretching across it and hiding the low-lying farther shore with its brilliancy. A few small boats moved slowly near the shore, while farther out an occasional large steamer came into view going up the fairway to Goole. Every now and then trains roared past, the steam hardly visible in the dry air.

The afternoon dragged slowly but not unpleasantly away, until about five o'clock they observed the first sign of activity about the syndicate's depot which had taken place since their arrival. The door in the galvanized fence opened and five figures emerged and slowly crossed the railway. They paused for a moment after reaching the lane, then separated, four going eastwards towards the distillery, the fifth coming north towards the point at which the watchers were concealed. The latter thereupon moved out from their hiding place on to the road.

The fifth figure resolved itself into that of a middle-aged man of the laboring class, slow, heavy, and obese. In his rather bovine countenance hardly any spark of intelligence shone. He did not appear to have seen the others as he approached, but evinced neither surprise nor interest when Hilliard accosted him.

"Any place about here you can get a drink?"

The man slowly jerked his head to the left.

"Oop in village," he answered. "Raven bar."

"Come along and show us the way and have a drink with us," Hilliard invited.

The man grasped this and his eyes gleamed.

"Ay," he replied succinctly.

As they walked Hilliard attempted light conversation, but without eliciting much response from their new acquaintance, and it was not until he had consumed his third bottle of beer that his tongue became somewhat looser.

"Any chance of a job where you're working?" Hilliard went on. "My pal and I would be glad to pick up something."

The man shook his head, apparently noticing nothing incongruous in the question.

"Don't think it."

"No harm in asking the boss anyway. Where might we find him?"

"Down at works likely. He be there most times."

"I'd rather go to his house. Can you tell where he lives?"

"Ay. Down at works."

"But he doesn't sleep at the works surely?"

"Ay. Sleeps in tin hut."

The friends exchanged glances. Their problem was even more difficult than they had supposed. A secret inspection seemed more and more unattainable. Hilliard continued the laborious conversation.

"We thought there might be some stevedoring to do. You've a steamer in now and then, haven't you?"

The man admitted it, and after a deal of wearisome questioning they learned that the Girondin called about every ten days, remaining for about forty-eight hours, and that she was due in three or four days.

Finding they could get no further information out of him, they left their bovine acquaintance with a fresh supply of beer, and returning to the station, took the first train back to Hull. As they sat smoking that evening after dinner they once more attacked the problem which was baffling them.

"It seems to me," Hilliard asserted, "that we should concentrate on the smuggling idea first, not because I quite believe in it, but because it's the only one we have. And that brings us again to the same point—the unloading of the Girondin."

Merriman not replying, he continued:

"Any attempt involves a preliminary visit to see how the land lies. Now we can't approach that place in the daytime; if we try to slip round secretly we shall be spotted from those windows or from the wharf; on the other hand, if we invent some tale and go openly, we give ourselves away if they have our descriptions or photographs. Therefore we must go at night."

"Well?"

"Obviously we can only approach the place by land or water. If we go by land we have either to shin up on the pier from the shore, which we're not certain we can do, or else risk making a noise climbing over the galvanized iron fence. Besides we might leave footmarks or other traces. But if we go by water we can muffle our oars and drop down absolutely silently to the wharf. There are bound to be steps, and it would be easy to get up without making any noise."

Merriman's emphatic nod expressed his approval.

"Good," he cried warmly. "What about getting a boat to-morrow and having a try that night?"

"I think we should. There's another thing about it too. If there should be an alarm we could get away by the river far more easily than across the country. It's a blessing there's no moon."

Next day the object of their search was changed. They wanted a small, handy skiff on hire. It did not turn out an easy quest, but by the late afternoon they succeeded in obtaining the desired article. They purchased also close-fitting caps and rubber-soled shoes, together with some food for the night, a couple of electric torches, and a yard of black cloth. Then, shortly before dusk began to fall, they took their places and pulled out on the great stream.

It was a pleasant evening, a fitting close to a glorious day. The air was soft and balmy, and a faint haze hung over the water, smoothing and blurring the sharp outlines of the buildings of the town and turning the opposite bank into a gray smudge. Not a breath was stirring, and the water lay like plate glass, unbroken by the faintest ripple. The spirit of adventure was high in the two men as they pulled down the great avenue of burnished gold stretching westwards towards the sinking sun.

The tide was flowing, and but slight effort was needed to keep them moving up-stream. As darkness grew they came nearer inshore, until in the fading light they recognized the railway station at Hassle. There they ceased rowing, drifting slowly onwards until the last faint haze of light had disappeared from the sky.

They had carefully muffled their oars, and now they turned north and began sculling gently inshore. Several lights had come out, and presently they recognized the railway signals and cabin at the distillery sidings.

"Two or three hundred yards more," said Hilliard in low tones.

They were now close to the beach, and they allowed themselves to drift on until the dark mass of the wharf loomed up ahead. Then Hilliard dipped his oars and brought the boat silently alongside.

As they had imagined from their distant view of it, the wharf was identically similar in construction to that on the River Lesque. Here also were the two lines of piles like the letter V, one, in front vertical, the other raking to support the earthwork behind. Here in the same relative position were the steps, and to these Hilliard made fast the painter with a slip hitch that could be quickly released. Then with the utmost caution both men stepped ashore, and slowly mounting the steps, peeped out over the deck of the wharf.

As far as they could make out in the gloom, the arrangement here also was similar to that in France. Lines of narrow gauge tramway, running parallel from the hut towards the water, were connected along the front of the wharf by a cross road and turn-tables. Between the lines were stacks of pit-props, and Decauville trucks stood here and there. But these details they saw afterwards. What first attracted their attention was that lights shone in the third and fourth windows from the left hand end of the shed. The manager evidently was still about.

"We'll go back to the boat and wait," Hilliard whispered, and they crept down the steps.

At intervals of half an hour one or other climbed up and had a look at the windows. On the first two occasions the light was unchanged, on the third it had moved to the first and second windows, and on the fourth it had gone, apparently indicating that the manager had moved from his sitting-room to his bedroom and retired.

"We had better wait at least an hour more," Hilliard whispered again.

Time passed slowly in the darkness under the wharf, and in a silence broken only by the gentle lapping of the water among the piles. The boat lay almost steady, except when a movement of one of its occupants made it heel slightly over and started a series of tiny ripples. It was not cold, and had the men not been so full of their adventure they could have slept. At intervals Hilliard consulted his luminous-dialed watch, but it was not until the hands pointed to the half-hour after one that they made a move. Then once more they softly ascended to the wharf above.

The sides of the structure were protected by railings which ran back to the gables of the tin house, the latter stretching entirely across the base of the pier. Over the space thus enclosed the two friends passed, but it speedily became apparent that here nothing of interest was to be found. Beyond the stacks of props and wagons there was literally nothing except a rusty steam winch, a large water butt into which was led the down spout from the roof, a tank raised on a stand and fitted with a flexible pipe, evidently for supplying crude oil for the ship's engines, and a number of empty barrels in which the oil had been delivered. With their torch carefully screened by the black cloth the friends examined these objects, particularly the oil tank which, forming as it did a bridge between ship and shore, naturally came in for its share of suspicion. But, they were soon satisfied that neither it nor any of the other objects were connected with their quest, and retreating to the edge of the wharf, they held a whispered consultation.

Hilliard was for attempting to open one of the doors in the shed at the end away from the manager's room, but Merriman, obsessed with the idea of seeing the unloading of the Girondin, urged that the contents of the shed were secondary, and that their efforts should be confined to discovering a hiding place from which the necessary observations could be made.

"If there was any way of getting inside one of these stacks of props," he said, "we could keep a perfect watch. I could get in now, for example; you relieve me tomorrow night; I relieve you the next night, and so on. Nothing could be unloaded that we wouldn't see. But," he added regretfully, "I doubt even if we could get inside that we should be hidden. Besides, they might take a notion to load the props up."

"Afraid that is hardly the scheme," Hilliard answered, then went on excitedly: "But, there's that barrel! Perhaps we could get into that."

"The barrel! That's the ticket." Merriman was excited in his turn. "That is, if it has a lid."

They retraced their steps. With the tank they did not trouble; it was a galvanized iron box with the lid riveted on, and moreover was full of oil; but the barrel looked feasible.

It was an exceptionally large cask or butt, with a lid which projected over its upper rim and which entirely protected the interior from view. It was placed in the corner beside the right hand gable of the shed, that is, the opposite end of the manager's rooms, and the wooden down spout from the roof passed in through a slot cut in the edge of the lid. A more ideal position for an observation post could hardly have been selected.

"Try to lift the lid," whispered Hilliard.

They found it was merely laid on the rim, cleats nailed on below preventing it from slipping off. They raised it easily and Hilliard flashed in a beam from his electric torch. The cask was empty, evidently a result of the long drought.

"That'll do," Merriman breathed. "That's all we want to see. Come away."

They lowered the cover and stood for a moment. Hilliard still wanted to try the doors of the shed, but Merriman would not hear of it.

"Come away," he whispered again. "We've done well. Why spoil it?"

They returned to the boat and there argued it out. Merriman's proposal was to try to find out when the Girondin was expected, then come the night before, bore a few eyeholes in the cask, and let one of them, properly supplied with provisions, get inside and assume watch. The other one would row away, rest and sleep during the day, and return on the following night, when they would exchange roles, and so on until the Girondin left. In this way, he asserted, they must infallibly discover the truth, at least about the smuggling.

"Do you think we could stand twenty-four hours in that barrel?" Hilliard questioned.

"Of course we could stand it. We've got to. Come on, Hilliard, it's the only way."

It did not require much persuasion to get Hilliard to fall in with the proposal, and they untied their painter and pulled silently away from the wharf. The tide had turned, and soon they relaxed their efforts and let the boat drift gently downstream. The first faint light appeared in the eastern sky as they floated past Hassle, and for an hour afterwards they lay in the bottom of the boat, smoking peacefully and entranced by the gorgeous pageant of the coming day.

Not wishing to reach Hull too early, they rowed inshore and, landing in a little bay, lay down in the lush grass and slept for three or four hours. Then re-embarking, they pulled and drifted on until, between seven and eight o'clock, they reached the wharf at which they had hired their boat. An hour later they were back at their hotel, recuperating from the fatigues of the night with the help of cold baths and a substantial breakfast.



CHAPTER 8. THE UNLOADING OF THE "GIRONDIN"

After breakfast Hilliard disappeared. He went out ostensibly to post a letter, but it was not until nearly three o'clock that he turned up again.

"Sorry, old man," he greeted Merriman, "but when I was going to the post office this morning an idea struck me, and it took me longer to follow up than I anticipated. I'll tell you. I suppose you realize that life in that barrel won't be very happy for the victim?"

"It'll be damnable," Merriman agreed succinctly, "but we needn't worry about that; we're in for it."

"Oh, quite," Hilliard returned. "But just for that reason we don't want more of it than is necessary. We could easily bury ourselves twenty-four hours too soon."

"Meaning?"

"Meaning that we mustn't go back to the wharf until the night before the Girondin arrives."

"Don't see how we can be sure of that."

"Nor did I till I posted my letter. Then I got my idea. It seemed worth following up, so I went round the shipping offices until I found a file of Lloyd's List. As you know it's a daily paper which gives the arrivals and departures of all ships at the world's ports. My notion was that if we could make a list of the Girondin's Ferriby arrivals and departures, say, during the last three months, and if we found she ran her trip regularly, we could forecast when she would be next due. Follow me?"

"Rather."

"I had no trouble getting out my list, but I found it a bit disappointing. The trip took either ten, eleven, or twelve days, and for a long time I couldn't discover the ruling factor. Then I found it was Sunday. If you omit each Sunday the Girondin is in port, the round trip always takes the even ten days. I had the Lesque arrival and departure for that one trip when we were there, so I was able to make out the complete cycle. She takes two days in the Lesque to load, three to run to Hull, two at Ferriby to discharge, and three to return to France. Working from that and her last call here, she should be due back early on Friday morning."

"Good!" Merriman exclaimed. "Jolly good! And today is Thursday. We've just time to get ready."

They went out and bought a one-inch auger and a three-sixteenths bradawl, a thick footstool and a satchel. This latter they packed with a loaf, some cheese, a packet of figs, a few bottles of soda water and a flask of whisky. These, with their caps, rubber shoes, electric torches and the black cloth, they carried to their boat; then returning to the hotel, they spent the time resting there until eleven o'clock. Solemnly they drew lots for the first watch, recognizing that the matter was by no means a joke, as, if unloading were carried on by night, relief might be impossible during the ship's stay. But Merriman, to whom the fates were propitious, had no fear of his ability to hold out even for this period.

By eleven-thirty they were again sculling up the river. The weather was as perfect as that of the night before, except that on this occasion a faint westerly breeze had covered the surface of the water with myriads of tiny wavelets, which lapped and gurgled round the stem of their boat as they drove it gently through them. They did not hurry, and it was after one before they moored to the depot steps.

All was dark and silent above, as, carrying their purchases, they mounted to the wharf and crept stealthily to the barrel. Carefully they raised the lid, and Merriman, standing on the footstool, with some difficulty squeezed himself inside. Hilliard then lifted the footstool on to the rim and lowered the lid on to it, afterwards passing in through the opening thus left the satchel of food and the one-inch auger.

A means of observation now remained to be made. Two holes, they thought, should afford all the view necessary, one looking towards the front of the wharf, and the other at right angles, along the side of the shed. Slowly, from the inside, Merriman began to bore. He made a sound like the nibbling of a mouse, but worked at irregular speeds so as not to suggest human agency to anyone who might be awake and listening. Hilliard, with his hand on the outside of the barrel, stopped the work when he felt the point of the auger coming through, and he himself completed the hole from the outside with his bradawl. This gave an aperture imperceptible on the rough exterior, but large within, and enabled the watcher to see through a much wider angle than he could otherwise have done. Hilliard then once more raised the lid, allowing Merriman to lift the footstool within, where it was destined to act as a seat for the observer.

All was now complete, and with a whispered exchange of good wishes, Hilliard withdrew, having satisfied himself by a careful look round that no traces had been left. Regaining the boat, he loosed the painter and pulled gently away into the night.

Left to himself in the confined space and inky blackness of the cask, Merriman proceeded to take stock of his position. He was anxious if possible to sleep, not only to pass some of the time, which at the best would inevitably be terribly long, but also that he might be the more wakeful when his attention should be required. But his unusual surroundings stimulated his imagination, and he could not rest.

He was surprised that the air was so good. Fortunately, the hole through the lid which received the down spout was of large dimensions, so that even though he might not have plenty of air, he would be in no danger of asphyxiation.

The night was very still. Listening intently, he could not hear the slightest sound. The silence and utter darkness indeed soon became overpowering, and he took his watch from his pocket that he might have the companionship of its ticking and see the glimmering hands and ring of figures.

He gave himself up for the thousandth time to the consideration of the main problem. What were the syndicate people doing? Was Mr. Coburn liable to prosecution, to penal servitude? Was it possible that by some twist of the legal mind, some misleading circumstantial evidence, Miss Coburn—Madeleine—could be incriminated? Oh, if he but knew what was wrong, that he might be able to help! If he could but get her out of it, and for her sake Mr. Coburn! If they were once safe he could pass on his knowledge to the police and be quit of the whole business. But always there was this enveloping cloak of ignorance baffling him at every turn. He did not know what was wrong, and any step he attempted might just precipitate the calamity he most desired to avoid.
