Adam suddenly changed to another phase of the subject.

"And now, sir, may I turn for a few minutes to purely practical things, or rather to matters of historical fact?"

Sir Nathaniel bowed acquiescence.

"We have already spoken of the history, so far as it is known, of some of the places round us—'Castra Regis,' 'Diana's Grove,' and 'The Lair of the White Worm.' I would like to ask if there is anything not necessarily of evil import about any of the places?"

"Which?" asked Sir Nathaniel shrewdly.

"Well, for instance, this house and Mercy Farm?"

"Here we turn," said Sir Nathaniel, "to the other side, the light side of things. Let us take Mercy Farm first. When Augustine was sent by Pope Gregory to Christianise England, in the time of the Romans, he was received and protected by Ethelbert, King of Kent, whose wife, daughter of Charibert, King of Paris, was a Christian, and did much for Augustine. She founded a nunnery in memory of Columba, which was named Sedes misericordioe, the House of Mercy, and, as the region was Mercian, the two names became involved. As Columba is the Latin for dove, the dove became a sort of signification of the nunnery. She seized on the idea and made the newly-founded nunnery a house of doves. Someone sent her a freshly-discovered dove, a sort of carrier, but which had in the white feathers of its head and neck the form of a religious cowl. The nunnery flourished for more than a century, when, in the time of Penda, who was the reactionary of heathendom, it fell into decay. In the meantime the doves, protected by religious feeling, had increased mightily, and were known in all Catholic communities. When King Offa ruled in Mercia, about a hundred and fifty years later, he restored Christianity, and under its protection the nunnery of St. Columba was restored and its doves flourished again. In process of time this religious house again fell into desuetude; but before it disappeared it had achieved a great name for good works, and in especial for the piety of its members. If deeds and prayers and hopes and earnest thinking leave anywhere any moral effect, Mercy Farm and all around it have almost the right to be considered holy ground."

"Thank you, sir," said Adam earnestly, and was silent. Sir Nathaniel understood.

After lunch that day, Adam casually asked Sir Nathaniel to come for a walk with him. The keen-witted old diplomatist guessed that there must be some motive behind the suggestion, and he at once agreed.

As soon as they were free from observation, Adam began.

"I am afraid, sir, that there is more going on in this neighbourhood than most people imagine. I was out this morning, and on the edge of the small wood, I came upon the body of a child by the roadside. At first, I thought she was dead, and while examining her, I noticed on her neck some marks that looked like those of teeth."

"Some wild dog, perhaps?" put in Sir Nathaniel.

"Possibly, sir, though I think not—but listen to the rest of my news. I glanced around, and to my surprise, I noticed something white moving among the trees. I placed the child down carefully, and followed, but I could not find any further traces. So I returned to the child and resumed my examination, and, to my delight, I discovered that she was still alive. I chafed her hands and gradually she revived, but to my disappointment she remembered nothing—except that something had crept up quietly from behind, and had gripped her round the throat. Then, apparently, she fainted."

"Gripped her round the throat! Then it cannot have been a dog."

"No, sir, that is my difficulty, and explains why I brought you out here, where we cannot possibly be overheard. You have noticed, of course, the peculiar sinuous way in which Lady Arabella moves—well, I feel certain that the white thing that I saw in the wood was the mistress of Diana's Grove!"

"Good God, boy, be careful what you say."

"Yes, sir, I fully realise the gravity of my accusation, but I feel convinced that the marks on the child's throat were human—and made by a woman."

Adam's companion remained silent for some time, deep in thought.

"Adam, my boy," he said at last, "this matter appears to me to be far more serious even than you think. It forces me to break confidence with my old friend, your uncle—but, in order to spare him, I must do so. For some time now, things have been happening in this district that have been worrying him dreadfully—several people have disappeared, without leaving the slightest trace; a dead child was found by the roadside, with no visible or ascertainable cause of death—sheep and other animals have been found in the fields, bleeding from open wounds. There have been other matters—many of them apparently trivial in themselves. Some sinister influence has been at work, and I admit that I have suspected Lady Arabella—that is why I questioned you so closely about the mongoose and its strange attack upon Lady Arabella. You will think it strange that I should suspect the mistress of Diana's Grove, a beautiful woman of aristocratic birth. Let me explain—the family seat is near my own place, Doom Tower, and at one time I knew the family well. When still a young girl, Lady Arabella wandered into a small wood near her home, and did not return. She was found unconscious and in a high fever—the doctor said that she had received a poisonous bite, and the girl being at a delicate and critical age, the result was serious—so much so that she was not expected to recover. A great London physician came down but could do nothing—indeed, he said that the girl would not survive the night. All hope had been abandoned, when, to everyone's surprise, Lady Arabella made a sudden and startling recovery. Within a couple of days she was going about as usual! But to the horror of her people, she developed a terrible craving for cruelty, maiming and injuring birds and small animals—even killing them. This was put down to a nervous disturbance due to her age, and it was hoped that her marriage to Captain March would put this right. However, it was not a happy marriage, and eventually her husband was found shot through the head. I have always suspected suicide, though no pistol was found near the body. He may have discovered something—God knows what!—so possibly Lady Arabella may herself have killed him. Putting together many small matters that have come to my knowledge, I have come to the conclusion that the foul White Worm obtained control of her body, just as her soul was leaving its earthly tenement—that would explain the sudden revival of energy, the strange and inexplicable craving for maiming and killing, as well as many other matters with which I need not trouble you now, Adam. As I said just now, God alone knows what poor Captain March discovered—it must have been something too ghastly for human endurance, if my theory is correct that the once beautiful human body of Lady Arabella is under the control of this ghastly White Worm."

Adam nodded.

"But what can we do, sir—it seems a most difficult problem."

"We can do nothing, my boy—that is the important part of it. It would be impossible to take action—all we can do is to keep careful watch, especially as regards Lady Arabella, and be ready to act, promptly and decisively, if the opportunity occurs."

Adam agreed, and the two men returned to Lesser Hill.



CHAPTER IX—SMELLING DEATH

Adam Salton, though he talked little, did not let the grass grow under his feet in any matter which he had undertaken, or in which he was interested. He had agreed with Sir Nathaniel that they should not do anything with regard to the mystery of Lady Arabella's fear of the mongoose, but he steadily pursued his course in being prepared to act whenever the opportunity might come. He was in his own mind perpetually casting about for information or clues which might lead to possible lines of action. Baffled by the killing of the mongoose, he looked around for another line to follow. He was fascinated by the idea of there being a mysterious link between the woman and the animal, but he was already preparing a second string to his bow. His new idea was to use the faculties of Oolanga, so far as he could, in the service of discovery. His first move was to send Davenport to Liverpool to try to find the steward of the West African, who had told him about Oolanga, and if possible secure any further information, and then try to induce (by bribery or other means) the nigger to come to the Brow. So soon as he himself could have speech of the Voodoo-man he would be able to learn from him something useful. Davenport was successful in his missions, for he had to get another mongoose, and he was able to tell Adam that he had seen the steward, who told him much that he wanted to know, and had also arranged for Oolanga to come to Lesser Hill the following day. At this point Adam saw his way sufficiently clear to admit Davenport to some extent into his confidence. He had come to the conclusion that it would be better—certainly at first—not himself to appear in the matter, with which Davenport was fully competent to deal. It would be time for himself to take a personal part when matters had advanced a little further.

If what the nigger said was in any wise true, the man had a rare gift which might be useful in the quest they were after. He could, as it were, "smell death." If any one was dead, if any one had died, or if a place had been used in connection with death, he seemed to know the broad fact by intuition. Adam made up his mind that to test this faculty with regard to several places would be his first task. Naturally he was anxious, and the time passed slowly. The only comfort was the arrival the next morning of a strong packing case, locked, from Ross, the key being in the custody of Davenport. In the case were two smaller boxes, both locked. One of them contained a mongoose to replace that killed by Lady Arabella; the other was the special mongoose which had already killed the king-cobra in Nepaul. When both the animals had been safely put under lock and key, he felt that he might breathe more freely. No one was allowed to know the secret of their existence in the house, except himself and Davenport. He arranged that Davenport should take Oolanga round the neighbourhood for a walk, stopping at each of the places which he designated. Having gone all along the Brow, he was to return the same way and induce him to touch on the same subjects in talking with Adam, who was to meet them as if by chance at the farthest part—that beyond Mercy Farm.

The incidents of the day proved much as Adam expected. At Mercy Farm, at Diana's Grove, at Castra Regis, and a few other spots, the negro stopped and, opening his wide nostrils as if to sniff boldly, said that he smelled death. It was not always in the same form. At Mercy Farm he said there were many small deaths. At Diana's Grove his bearing was different. There was a distinct sense of enjoyment about him, especially when he spoke of many great deaths. Here, too, he sniffed in a strange way, like a bloodhound at check, and looked puzzled. He said no word in either praise or disparagement, but in the centre of the Grove, where, hidden amongst ancient oak stumps, was a block of granite slightly hollowed on the top, he bent low and placed his forehead on the ground. This was the only place where he showed distinct reverence. At the Castle, though he spoke of much death, he showed no sign of respect.

There was evidently something about Diana's Grove which both interested and baffled him. Before leaving, he moved all over the place unsatisfied, and in one spot, close to the edge of the Brow, where there was a deep hollow, he appeared to be afraid. After returning several times to this place, he suddenly turned and ran in a panic of fear to the higher ground, crossing as he did so the outcropping rock. Then he seemed to breathe more freely, and recovered some of his jaunty impudence.

All this seemed to satisfy Adam's expectations. He went back to Lesser Hill with a serene and settled calm upon him. Sir Nathaniel followed him into his study.

"By the way, I forgot to ask you details about one thing. When that extraordinary staring episode of Mr. Caswall went on, how did Lilla take it—how did she bear herself?"

"She looked frightened, and trembled just as I have seen a pigeon with a hawk, or a bird with a serpent."

"Thanks. It is just as I expected. There have been circumstances in the Caswall family which lead one to believe that they have had from the earliest times some extraordinary mesmeric or hypnotic faculty. Indeed, a skilled eye could read so much in their physiognomy. That shot of yours, whether by instinct or intention, of the hawk and the pigeon was peculiarly apposite. I think we may settle on that as a fixed trait to be accepted throughout our investigation."

When dusk had fallen, Adam took the new mongoose—not the one from Nepaul—and, carrying the box slung over his shoulder, strolled towards Diana's Grove. Close to the gateway he met Lady Arabella, clad as usual in tightly fitting white, which showed off her slim figure.

To his intense astonishment the mongoose allowed her to pet him, take him up in her arms and fondle him. As she was going in his direction, they walked on together.

Round the roadway between the entrances of Diana's Grove and Lesser Hill were many trees, with not much foliage except at the top. In the dusk this place was shadowy, and the view was hampered by the clustering trunks. In the uncertain, tremulous light which fell through the tree- tops, it was hard to distinguish anything clearly, and at last, somehow, he lost sight of her altogether, and turned back on his track to find her. Presently he came across her close to her own gate. She was leaning over the paling of split oak branches which formed the paling of the avenue. He could not see the mongoose, so he asked her where it had gone.

"He slipt out of my arms while I was petting him," she answered, "and disappeared under the hedges."

They found him at a place where the avenue widened so as to let carriages pass each other. The little creature seemed quite changed. He had been ebulliently active; now he was dull and spiritless—seemed to be dazed. He allowed himself to be lifted by either of the pair; but when he was alone with Lady Arabella he kept looking round him in a strange way, as though trying to escape. When they had come out on the roadway Adam held the mongoose tight to him, and, lifting his hat to his companion, moved quickly towards Lesser Hill; he and Lady Arabella lost sight of each other in the thickening gloom.

When Adam got home, he put the mongoose in his box, and locked the door of the room. The other mongoose—the one from Nepaul—was safely locked in his own box, but he lay quiet and did not stir. When he got to his study Sir Nathaniel came in, shutting the door behind him.

"I have come," he said, "while we have an opportunity of being alone, to tell you something of the Caswall family which I think will interest you. There is, or used to be, a belief in this part of the world that the Caswall family had some strange power of making the wills of other persons subservient to their own. There are many allusions to the subject in memoirs and other unimportant works, but I only know of one where the subject is spoken of definitely. It is Mercia and its Worthies, written by Ezra Toms more than a hundred years ago. The author goes into the question of the close association of the then Edgar Caswall with Mesmer in Paris. He speaks of Caswall being a pupil and the fellow worker of Mesmer, and states that though, when the latter left France, he took away with him a vast quantity of philosophical and electric instruments, he was never known to use them again. He once made it known to a friend that he had given them to his old pupil. The term he used was odd, for it was 'bequeathed,' but no such bequest of Mesmer was ever made known. At any rate the instruments were missing, and never turned up."

A servant came into the room to tell Adam that there was some strange noise coming from the locked room into which he had gone when he came in. He hurried off to the place at once, Sir Nathaniel going with him. Having locked the door behind them, Adam opened the packing-case where the boxes of the two mongooses were locked up. There was no sound from one of them, but from the other a queer restless struggling. Having opened both boxes, he found that the noise was from the Nepaul animal, which, however, became quiet at once. In the other box the new mongoose lay dead, with every appearance of having been strangled!



CHAPTER X—THE KITE

On the following day, a little after four o'clock, Adam set out for Mercy.

He was home just as the clocks were striking six. He was pale and upset, but otherwise looked strong and alert. The old man summed up his appearance and manner thus: "Braced up for battle."

"Now!" said Sir Nathaniel, and settled down to listen, looking at Adam steadily and listening attentively that he might miss nothing—even the inflection of a word.

"I found Lilla and Mimi at home. Watford had been detained by business on the farm. Miss Watford received me as kindly as before; Mimi, too, seemed glad to see me. Mr. Caswall came so soon after I arrived, that he, or someone on his behalf, must have been watching for me. He was followed closely by the negro, who was puffing hard as if he had been running—so it was probably he who watched. Mr. Caswall was very cool and collected, but there was a more than usually iron look about his face that I did not like. However, we got on very well. He talked pleasantly on all sorts of questions. The nigger waited a while and then disappeared as on the other occasion. Mr. Caswall's eyes were as usual fixed on Lilla. True, they seemed to be very deep and earnest, but there was no offence in them. Had it not been for the drawing down of the brows and the stern set of the jaws, I should not at first have noticed anything. But the stare, when presently it began, increased in intensity. I could see that Lilla began to suffer from nervousness, as on the first occasion; but she carried herself bravely. However, the more nervous she grew, the harder Mr. Caswall stared. It was evident to me that he had come prepared for some sort of mesmeric or hypnotic battle. After a while he began to throw glances round him and then raised his hand, without letting either Lilla or Mimi see the action. It was evidently intended to give some sign to the negro, for he came, in his usual stealthy way, quietly in by the hall door, which was open. Then Mr. Caswall's efforts at staring became intensified, and poor Lilla's nervousness grew greater. Mimi, seeing that her cousin was distressed, came close to her, as if to comfort or strengthen her with the consciousness of her presence. This evidently made a difficulty for Mr. Caswall, for his efforts, without appearing to get feebler, seemed less effective. This continued for a little while, to the gain of both Lilla and Mimi. Then there was a diversion. Without word or apology the door opened, and Lady Arabella March entered the room. I had seen her coming through the great window. Without a word she crossed the room and stood beside Mr. Caswall. It really was very like a fight of a peculiar kind; and the longer it was sustained the more earnest—the fiercer—it grew. That combination of forces—the over-lord, the white woman, and the black man—would have cost some—probably all of them—their lives in the Southern States of America. To us it was simply horrible. But all that you can understand. This time, to go on in sporting phrase, it was understood by all to be a 'fight to a finish,' and the mixed group did not slacken a moment or relax their efforts. On Lilla the strain began to tell disastrously. She grew pale—a patchy pallor, which meant that her nerves were out of order. She trembled like an aspen, and though she struggled bravely, I noticed that her legs would hardly support her. A dozen times she seemed about to collapse in a faint, but each time, on catching sight of Mimi's eyes, she made a fresh struggle and pulled through.

"By now Mr. Caswall's face had lost its appearance of passivity. His eyes glowed with a fiery light. He was still the old Roman in inflexibility of purpose; but grafted on to the Roman was a new Berserker fury. His companions in the baleful work seemed to have taken on something of his feeling. Lady Arabella looked like a soulless, pitiless being, not human, unless it revived old legends of transformed human beings who had lost their humanity in some transformation or in the sweep of natural savagery. As for the negro—well, I can only say that it was solely due to the self-restraint which you impressed on me that I did not wipe him out as he stood—without warning, without fair play—without a single one of the graces of life and death. Lilla was silent in the helpless concentration of deadly fear; Mimi was all resolve and self-forgetfulness, so intent on the soul-struggle in which she was engaged that there was no possibility of any other thought. As for myself, the bonds of will which held me inactive seemed like bands of steel which numbed all my faculties, except sight and hearing. We seemed fixed in an impasse. Something must happen, though the power of guessing was inactive. As in a dream, I saw Mimi's hand move restlessly, as if groping for something. Mechanically it touched that of Lilla, and in that instant she was transformed. It was as if youth and strength entered afresh into something already dead to sensibility and intention. As if by inspiration, she grasped the other's band with a force which blenched the knuckles. Her face suddenly flamed, as if some divine light shone through it. Her form expanded till it stood out majestically. Lifting her right hand, she stepped forward towards Caswall, and with a bold sweep of her arm seemed to drive some strange force towards him. Again and again was the gesture repeated, the man falling back from her at each movement. Towards the door he retreated, she following. There was a sound as of the cooing sob of doves, which seemed to multiply and intensify with each second. The sound from the unseen source rose and rose as he retreated, till finally it swelled out in a triumphant peal, as she with a fierce sweep of her arm, seemed to hurl something at her foe, and he, moving his hands blindly before his face, appeared to be swept through the doorway and out into the open sunlight.

"All at once my own faculties were fully restored; I could see and hear everything, and be fully conscious of what was going on. Even the figures of the baleful group were there, though dimly seen as through a veil—a shadowy veil. I saw Lilla sink down in a swoon, and Mimi throw up her arms in a gesture of triumph. As I saw her through the great window, the sunshine flooded the landscape, which, however, was momentarily becoming eclipsed by an onrush of a myriad birds."

By the next morning, daylight showed the actual danger which threatened. From every part of the eastern counties reports were received concerning the enormous immigration of birds. Experts were sending—on their own account, on behalf of learned societies, and through local and imperial governing bodies—reports dealing with the matter, and suggesting remedies.

The reports closer to home were even more disturbing. All day long it would seem that the birds were coming thicker from all quarters. Doubtless many were going as well as coming, but the mass seemed never to get less. Each bird seemed to sound some note of fear or anger or seeking, and the whirring of wings never ceased nor lessened. The air was full of a muttered throb. No window or barrier could shut out the sound, till the ears of any listener became dulled by the ceaseless murmur. So monotonous it was, so cheerless, so disheartening, so melancholy, that all longed, but in vain, for any variety, no matter how terrible it might be.

The second morning the reports from all the districts round were more alarming than ever. Farmers began to dread the coming of winter as they saw the dwindling of the timely fruitfulness of the earth. And as yet it was only a warning of evil, not the evil accomplished; the ground began to look bare whenever some passing sound temporarily frightened the birds.

Edgar Caswall tortured his brain for a long time unavailingly, to think of some means of getting rid of what he, as well as his neighbours, had come to regard as a plague of birds. At last he recalled a circumstance which promised a solution of the difficulty. The experience was of some years ago in China, far up-country, towards the head-waters of the Yang- tze-kiang, where the smaller tributaries spread out in a sort of natural irrigation scheme to supply the wilderness of paddy-fields. It was at the time of the ripening rice, and the myriads of birds which came to feed on the coming crop was a serious menace, not only to the district, but to the country at large. The farmers, who were more or less afflicted with the same trouble every season, knew how to deal with it. They made a vast kite, which they caused to be flown over the centre spot of the incursion. The kite was shaped like a great hawk; and the moment it rose into the air the birds began to cower and seek protection—and then to disappear. So long as that kite was flying overhead the birds lay low and the crop was saved. Accordingly Caswall ordered his men to construct an immense kite, adhering as well as they could to the lines of a hawk. Then he and his men, with a sufficiency of cord, began to fly it high overhead. The experience of China was repeated. The moment the kite rose, the birds hid or sought shelter. The following morning, the kite was still flying high, no bird was to be seen as far as the eye could reach from Castra Regis. But there followed in turn what proved even a worse evil. All the birds were cowed; their sounds stopped. Neither song nor chirp was heard—silence seemed to have taken the place of the normal voices of bird life. But that was not all. The silence spread to all animals.

The fear and restraint which brooded amongst the denizens of the air began to affect all life. Not only did the birds cease song or chirp, but the lowing of the cattle ceased in the fields and the varied sounds of life died away. In place of these things was only a soundless gloom, more dreadful, more disheartening, more soul-killing than any concourse of sounds, no matter how full of fear and dread. Pious individuals put up constant prayers for relief from the intolerable solitude. After a little there were signs of universal depression which those who ran might read. One and all, the faces of men and women seemed bereft of vitality, of interest, of thought, and, most of all, of hope. Men seemed to have lost the power of expression of their thoughts. The soundless air seemed to have the same effect as the universal darkness when men gnawed their tongues with pain.

From this infliction of silence there was no relief. Everything was affected; gloom was the predominant note. Joy appeared to have passed away as a factor of life, and this creative impulse had nothing to take its place. That giant spot in high air was a plague of evil influence. It seemed like a new misanthropic belief which had fallen on human beings, carrying with it the negation of all hope.

After a few days, men began to grow desperate; their very words as well as their senses seemed to be in chains. Edgar Caswall again tortured his brain to find any antidote or palliative of this greater evil than before. He would gladly have destroyed the kite, or caused its flying to cease; but the instant it was pulled down, the birds rose up in even greater numbers; all those who depended in any way on agriculture sent pitiful protests to Castra Regis.

It was strange indeed what influence that weird kite seemed to exercise. Even human beings were affected by it, as if both it and they were realities. As for the people at Mercy Farm, it was like a taste of actual death. Lilla felt it most. If she had been indeed a real dove, with a real kite hanging over her in the air, she could not have been more frightened or more affected by the terror this created.

Of course, some of those already drawn into the vortex noticed the effect on individuals. Those who were interested took care to compare their information. Strangely enough, as it seemed to the others, the person who took the ghastly silence least to heart was the negro. By nature he was not sensitive to, or afflicted by, nerves. This alone would not have produced the seeming indifference, so they set their minds to discover the real cause. Adam came quickly to the conclusion that there was for him some compensation that the others did not share; and he soon believed that that compensation was in one form or another the enjoyment of the sufferings of others. Thus the black had a never-failing source of amusement.

Lady Arabella's cold nature rendered her immune to anything in the way of pain or trouble concerning others. Edgar Caswall was far too haughty a person, and too stern of nature, to concern himself about poor or helpless people, much less the lower order of mere animals. Mr. Watford, Mr. Salton, and Sir Nathaniel were all concerned in the issue, partly from kindness of heart—for none of them could see suffering, even of wild birds, unmoved—and partly on account of their property, which had to be protected, or ruin would stare them in the face before long.

Lilla suffered acutely. As time went on, her face became pinched, and her eyes dull with watching and crying. Mimi suffered too on account of her cousin's suffering. But as she could do nothing, she resolutely made up her mind to self-restraint and patience. Adam's frequent visits comforted her.



CHAPTER XI—MESMER'S CHEST

After a couple of weeks had passed, the kite seemed to give Edgar Caswall a new zest for life. He was never tired of looking at its movements. He had a comfortable armchair put out on the tower, wherein he sat sometimes all day long, watching as though the kite was a new toy and he a child lately come into possession of it. He did not seem to have lost interest in Lilla, for he still paid an occasional visit at Mercy Farm.

Indeed, his feeling towards her, whatever it had been at first, had now so far changed that it had become a distinct affection of a purely animal kind. Indeed, it seemed as though the man's nature had become corrupted, and that all the baser and more selfish and more reckless qualities had become more conspicuous. There was not so much sternness apparent in his nature, because there was less self-restraint. Determination had become indifference.

The visible change in Edgar was that he grew morbid, sad, silent; the neighbours thought he was going mad. He became absorbed in the kite, and watched it not only by day, but often all night long. It became an obsession to him.

Caswall took a personal interest in the keeping of the great kite flying. He had a vast coil of cord efficient for the purpose, which worked on a roller fixed on the parapet of the tower. There was a winch for the pulling in of the slack; the outgoing line being controlled by a racket. There was invariably one man at least, day and night, on the tower to attend to it. At such an elevation there was always a strong wind, and at times the kite rose to an enormous height, as well as travelling for great distances laterally. In fact, the kite became, in a short time, one of the curiosities of Castra Regis and all around it. Edgar began to attribute to it, in his own mind, almost human qualities. It became to him a separate entity, with a mind and a soul of its own. Being idle- handed all day, he began to apply to what he considered the service of the kite some of his spare time, and found a new pleasure—a new object in life—in the old schoolboy game of sending up "runners" to the kite. The way this is done is to get round pieces of paper so cut that there is a hole in the centre, through which the string of the kite passes. The natural action of the wind-pressure takes the paper along the string, and so up to the kite itself, no matter how high or how far it may have gone.

In the early days of this amusement Edgar Caswall spent hours. Hundreds of such messengers flew along the string, until soon he bethought him of writing messages on these papers so that he could make known his ideas to the kite. It may be that his brain gave way under the opportunities given by his illusion of the entity of the toy and its power of separate thought. From sending messages he came to making direct speech to the kite—without, however, ceasing to send the runners. Doubtless, the height of the tower, seated as it was on the hill-top, the rushing of the ceaseless wind, the hypnotic effect of the lofty altitude of the speck in the sky at which he gazed, and the rushing of the paper messengers up the string till sight of them was lost in distance, all helped to further affect his brain, undoubtedly giving way under the strain of beliefs and circumstances which were at once stimulating to the imagination, occupative of his mind, and absorbing.

The next step of intellectual decline was to bring to bear on the main idea of the conscious identity of the kite all sorts of subjects which had imaginative force or tendency of their own. He had, in Castra Regis, a large collection of curious and interesting things formed in the past by his forebears, of similar tastes to his own. There were all sorts of strange anthropological specimens, both old and new, which had been collected through various travels in strange places: ancient Egyptian relics from tombs and mummies; curios from Australia, New Zealand, and the South Seas; idols and images—from Tartar ikons to ancient Egyptian, Persian, and Indian objects of worship; objects of death and torture of American Indians; and, above all, a vast collection of lethal weapons of every kind and from every place—Chinese "high pinders," double knives, Afghan double-edged scimitars made to cut a body in two, heavy knives from all the Eastern countries, ghost daggers from Thibet, the terrible kukri of the Ghourka and other hill tribes of India, assassins' weapons from Italy and Spain, even the knife which was formerly carried by the slave-drivers of the Mississippi region. Death and pain of every kind were fully represented in that gruesome collection.

That it had a fascination for Oolanga goes without saying. He was never tired of visiting the museum in the tower, and spent endless hours in inspecting the exhibits, till he was thoroughly familiar with every detail of all of them. He asked permission to clean and polish and sharpen them—a favour which was readily granted. In addition to the above objects, there were many things of a kind to awaken human fear. Stuffed serpents of the most objectionable and horrid kind; giant insects from the tropics, fearsome in every detail; fishes and crustaceans covered with weird spikes; dried octopuses of great size. Other things, too, there were, not less deadly though seemingly innocuous—dried fungi, traps intended for birds, beasts, fishes, reptiles, and insects; machines which could produce pain of any kind and degree, and the only mercy of which was the power of producing speedy death.

Caswall, who had never before seen any of these things, except those which he had collected himself, found a constant amusement and interest in them. He studied them, their uses, their mechanism—where there was such—and their places of origin, until he had an ample and real knowledge of all concerning them. Many were secret and intricate, but he never rested till he found out all the secrets. When once he had become interested in strange objects, and the way to use them, he began to explore various likely places for similar finds. He began to inquire of his household where strange lumber was kept. Several of the men spoke of old Simon Chester as one who knew everything in and about the house. Accordingly, he sent for the old man, who came at once. He was very old, nearly ninety years of age, and very infirm. He had been born in the Castle, and had served its succession of masters—present or absent—ever since. When Edgar began to question him on the subject regarding which he had sent for him, old Simon exhibited much perturbation. In fact, he became so frightened that his master, fully believing that he was concealing something, ordered him to tell at once what remained unseen, and where it was hidden away. Face to face with discovery of his secret, the old man, in a pitiable state of concern, spoke out even more fully than Mr. Caswall had expected.

"Indeed, indeed, sir, everything is here in the tower that has ever been put away in my time except—except—" here he began to shake and tremble it—"except the chest which Mr. Edgar—he who was Mr. Edgar when I first took service—brought back from France, after he had been with Dr. Mesmer. The trunk has been kept in my room for safety; but I shall send it down here now."

"What is in it?" asked Edgar sharply.

"That I do not know. Moreover, it is a peculiar trunk, without any visible means of opening."

"Is there no lock?"

"I suppose so, sir; but I do not know. There is no keyhole."

"Send it here; and then come to me yourself."

The trunk, a heavy one with steel bands round it, but no lock or keyhole, was carried in by two men. Shortly afterwards old Simon attended his master. When he came into the room, Mr. Caswall himself went and closed the door; then he asked:

"How do you open it?"

"I do not know, sir."

"Do you mean to say that you never opened it?"

"Most certainly I say so, your honour. How could I? It was entrusted to me with the other things by my master. To open it would have been a breach of trust."

Caswall sneered.

"Quite remarkable! Leave it with me. Close the door behind you. Stay—did no one ever tell you about it—say anything regarding it—make any remark?"

Old Simon turned pale, and put his trembling hands together.

"Oh, sir, I entreat you not to touch it. That trunk probably contains secrets which Dr. Mesmer told my master. Told them to his ruin!"

"How do you mean? What ruin?"

"Sir, he it was who, men said, sold his soul to the Evil One; I had thought that that time and the evil of it had all passed away."

"That will do. Go away; but remain in your own room, or within call. I may want you."

The old man bowed deeply and went out trembling, but without speaking a word.



CHAPTER XII—THE CHEST OPENED

Left alone in the turret-room, Edgar Caswall carefully locked the door and hung a handkerchief over the keyhole. Next, he inspected the windows, and saw that they were not overlooked from any angle of the main building. Then he carefully examined the trunk, going over it with a magnifying glass. He found it intact: the steel bands were flawless; the whole trunk was compact. After sitting opposite to it for some time, and the shades of evening beginning to melt into darkness, he gave up the task and went to his bedroom, after locking the door of the turret-room behind him and taking away the key.

He woke in the morning at daylight, and resumed his patient but unavailing study of the metal trunk. This he continued during the whole day with the same result—humiliating disappointment, which overwrought his nerves and made his head ache. The result of the long strain was seen later in the afternoon, when he sat locked within the turret-room before the still baffling trunk, distrait, listless and yet agitated, sunk in a settled gloom. As the dusk was falling he told the steward to send him two men, strong ones. These he ordered to take the trunk to his bedroom. In that room he then sat on into the night, without pausing even to take any food. His mind was in a whirl, a fever of excitement. The result was that when, late in the night, he locked himself in his room his brain was full of odd fancies; he was on the high road to mental disturbance. He lay down on his bed in the dark, still brooding over the mystery of the closed trunk.

Gradually he yielded to the influences of silence and darkness. After lying there quietly for some time, his mind became active again. But this time there were round him no disturbing influences; his brain was active and able to work freely and to deal with memory. A thousand forgotten—or only half-known—incidents, fragments of conversations or theories long ago guessed at and long forgotten, crowded on his mind. He seemed to hear again around him the legions of whirring wings to which he had been so lately accustomed. Even to himself he knew that that was an effort of imagination founded on imperfect memory. But he was content that imagination should work, for out of it might come some solution of the mystery which surrounded him. And in this frame of mind, sleep made another and more successful essay. This time he enjoyed peaceful slumber, restful alike to his wearied body and his overwrought brain.

In his sleep he arose, and, as if in obedience to some influence beyond and greater than himself, lifted the great trunk and set it on a strong table at one side of the room, from which he had previously removed a quantity of books. To do this, he had to use an amount of strength which was, he knew, far beyond him in his normal state. As it was, it seemed easy enough; everything yielded before his touch. Then he became conscious that somehow—how, he never could remember—the chest was open. He unlocked his door, and, taking the chest on his shoulder, carried it up to the turret-room, the door of which also he unlocked. Even at the time he was amazed at his own strength, and wondered whence it had come. His mind, lost in conjecture, was too far off to realise more immediate things. He knew that the chest was enormously heavy. He seemed, in a sort of vision which lit up the absolute blackness around, to see the two sturdy servant men staggering under its great weight. He locked himself again in the turret-room, and laid the opened chest on a table, and in the darkness began to unpack it, laying out the contents, which were mainly of metal and glass—great pieces in strange forms—on another table. He was conscious of being still asleep, and of acting rather in obedience to some unseen and unknown command than in accordance with any reasonable plan, to be followed by results which he understood. This phase completed, he proceeded to arrange in order the component parts of some large instruments, formed mostly of glass. His fingers seemed to have acquired a new and exquisite subtlety and even a volition of their own. Then weariness of brain came upon him; his head sank down on his breast, and little by little everything became wrapped in gloom.

He awoke in the early morning in his bedroom, and looked around him, now clear-headed, in amazement. In its usual place on the strong table stood the great steel-hooped chest without lock or key. But it was now locked. He arose quietly and stole to the turret-room. There everything was as it had been on the previous evening. He looked out of the window where high in air flew, as usual, the giant kite. He unlocked the wicket gate of the turret stair and went out on the roof. Close to him was the great coil of cord on its reel. It was humming in the morning breeze, and when he touched the string it sent a quick thrill through hand and arm. There was no sign anywhere that there had been any disturbance or displacement of anything during the night.

Utterly bewildered, he sat down in his room to think. Now for the first time he felt that he was asleep and dreaming. Presently he fell asleep again, and slept for a long time. He awoke hungry and made a hearty meal. Then towards evening, having locked himself in, he fell asleep again. When he woke he was in darkness, and was quite at sea as to his whereabouts. He began feeling about the dark room, and was recalled to the consequences of his position by the breaking of a large piece of glass. Having obtained a light, he discovered this to be a glass wheel, part of an elaborate piece of mechanism which he must in his sleep have taken from the chest, which was now opened. He had once again opened it whilst asleep, but he had no recollection of the circumstances.

Caswall came to the conclusion that there had been some sort of dual action of his mind, which might lead to some catastrophe or some discovery of his secret plans; so he resolved to forgo for a while the pleasure of making discoveries regarding the chest. To this end, he applied himself to quite another matter—an investigation of the other treasures and rare objects in his collections. He went amongst them in simple, idle curiosity, his main object being to discover some strange item which he might use for experiment with the kite. He had already resolved to try some runners other than those made of paper. He had a vague idea that with such a force as the great kite straining at its leash, this might be used to lift to the altitude of the kite itself heavier articles. His first experiment with articles of little but increasing weight was eminently successful. So he added by degrees more and more weight, until he found out that the lifting power of the kite was considerable. He then determined to take a step further, and send to the kite some of the articles which lay in the steel-hooped chest. The last time he had opened it in sleep, it had not been shut again, and he had inserted a wedge so that he could open it at will. He made examination of the contents, but came to the conclusion that the glass objects were unsuitable. They were too light for testing weight, and they were so frail as to be dangerous to send to such a height.

So he looked around for something more solid with which to experiment. His eye caught sight of an object which at once attracted him. This was a small copy of one of the ancient Egyptian gods—that of Bes, who represented the destructive power of nature. It was so bizarre and mysterious as to commend itself to his mad humour. In lifting it from the cabinet, he was struck by its great weight in proportion to its size. He made accurate examination of it by the aid of some instruments, and came to the conclusion that it was carved from a lump of lodestone. He remembered that he had read somewhere of an ancient Egyptian god cut from a similar substance, and, thinking it over, he came to the conclusion that he must have read it in Sir Thomas Brown's Popular Errors, a book of the seventeenth century. He got the book from the library, and looked out the passage:

"A great example we have from the observation of our learned friend Mr. Graves, in an AEgyptian idol cut out of Loadstone and found among the Mummies; which still retains its attraction, though probably taken out of the mine about two thousand years ago."

The strangeness of the figure, and its being so close akin to his own nature, attracted him. He made from thin wood a large circular runner, and in front of it placed the weighty god, sending it up to the flying kite along the throbbing cord.



CHAPTER XIII—OOLANGA'S HALLUCINATIONS

During the last few days Lady Arabella had been getting exceedingly impatient. Her debts, always pressing, were growing to an embarrassing amount. The only hope she had of comfort in life was a good marriage; but the good marriage on which she had fixed her eye did not seem to move quickly enough—indeed, it did not seem to move at all—in the right direction. Edgar Caswall was not an ardent wooer. From the very first he seemed difficile, but he had been keeping to his own room ever since his struggle with Mimi Watford. On that occasion Lady Arabella had shown him in an unmistakable way what her feelings were; indeed, she had made it known to him, in a more overt way than pride should allow, that she wished to help and support him. The moment when she had gone across the room to stand beside him in his mesmeric struggle, had been the very limit of her voluntary action. It was quite bitter enough, she felt, that he did not come to her, but now that she had made that advance, she felt that any withdrawal on his part would, to a woman of her class, be nothing less than a flaming insult. Had she not classed herself with his nigger servant, an unreformed savage? Had she not shown her preference for him at the festival of his home-coming? Had she not . . . Lady Arabella was cold-blooded, and she was prepared to go through all that might be necessary of indifference, and even insult, to become chatelaine of Castra Regis. In the meantime, she would show no hurry—she must wait. She might, in an unostentatious way, come to him again. She knew him now, and could make a keen guess at his desires with regard to Lilla Watford. With that secret in her possession, she could bring pressure to bear on Caswall which would make it no easy matter for him to evade her. The great difficulty was how to get near him. He was shut up within his Castle, and guarded by a defence of convention which she could not pass without danger of ill repute to herself. Over this question she thought and thought for days and nights. At last she decided that the only way would be to go to him openly at Castra Regis. Her rank and position would make such a thing possible, if carefully done. She could explain matters afterwards if necessary. Then when they were alone, she would use her arts and her experience to make him commit himself. After all, he was only a man, with a man's dislike of difficult or awkward situations. She felt quite sufficient confidence in her own womanhood to carry her through any difficulty which might arise.

From Diana's Grove she heard each day the luncheon-gong from Castra Regis sound, and knew the hour when the servants would be in the back of the house. She would enter the house at that hour, and, pretending that she could not make anyone hear her, would seek him in his own rooms. The tower was, she knew, away from all the usual sounds of the house, and moreover she knew that the servants had strict orders not to interrupt him when he was in the turret chamber. She had found out, partly by the aid of an opera-glass and partly by judicious questioning, that several times lately a heavy chest had been carried to and from his room, and that it rested in the room each night. She was, therefore, confident that he had some important work on hand which would keep him busy for long spells.

Meanwhile, another member of the household at Castra Regis had schemes which he thought were working to fruition. A man in the position of a servant has plenty of opportunity of watching his betters and forming opinions regarding them. Oolanga was in his way a clever, unscrupulous rogue, and he felt that with things moving round him in this great household there should be opportunities of self-advancement. Being unscrupulous and stealthy—and a savage—he looked to dishonest means. He saw plainly enough that Lady Arabella was making a dead set at his master, and he was watchful of the slightest sign of anything which might enhance this knowledge. Like the other men in the house, he knew of the carrying to and fro of the great chest, and had got it into his head that the care exercised in its porterage indicated that it was full of treasure. He was for ever lurking around the turret-rooms on the chance of making some useful discovery. But he was as cautious as he was stealthy, and took care that no one else watched him.

It was thus that the negro became aware of Lady Arabella's venture into the house, as she thought, unseen. He took more care than ever, since he was watching another, that the positions were not reversed. More than ever he kept his eyes and ears open and his mouth shut. Seeing Lady Arabella gliding up the stairs towards his master's room, he took it for granted that she was there for no good, and doubled his watching intentness and caution.

Oolanga was disappointed, but he dared not exhibit any feeling lest it should betray that he was hiding. Therefore he slunk downstairs again noiselessly, and waited for a more favourable opportunity of furthering his plans. It must be borne in mind that he thought that the heavy trunk was full of valuables, and that he believed that Lady Arabella had come to try to steal it. His purpose of using for his own advantage the combination of these two ideas was seen later in the day. Oolanga secretly followed her home. He was an expert at this game, and succeeded admirably on this occasion. He watched her enter the private gate of Diana's Grove, and then, taking a roundabout course and keeping out of her sight, he at last overtook her in a thick part of the Grove where no one could see the meeting.

Lady Arabella was much surprised. She had not seen the negro for several days, and had almost forgotten his existence. Oolanga would have been startled had he known and been capable of understanding the real value placed on him, his beauty, his worthiness, by other persons, and compared it with the value in these matters in which he held himself. Doubtless Oolanga had his dreams like other men. In such cases he saw himself as a young sun-god, as beautiful as the eye of dusky or even white womanhood had ever dwelt upon. He would have been filled with all noble and captivating qualities—or those regarded as such in West Africa. Women would have loved him, and would have told him so in the overt and fervid manner usual in affairs of the heart in the shadowy depths of the forest of the Gold Coast.

Oolanga came close behind Lady Arabella, and in a hushed voice, suitable to the importance of his task, and in deference to the respect he had for her and the place, began to unfold the story of his love. Lady Arabella was not usually a humorous person, but no man or woman of the white race could have checked the laughter which rose spontaneously to her lips. The circumstances were too grotesque, the contrast too violent, for subdued mirth. The man a debased specimen of one of the most primitive races of the earth, and of an ugliness which was simply devilish; the woman of high degree, beautiful, accomplished. She thought that her first moment's consideration of the outrage—it was nothing less in her eyes—had given her the full material for thought. But every instant after threw new and varied lights on the affront. Her indignation was too great for passion; only irony or satire would meet the situation. Her cold, cruel nature helped, and she did not shrink to subject this ignorant savage to the merciless fire-lash of her scorn.

Oolanga was dimly conscious that he was being flouted; but his anger was no less keen because of the measure of his ignorance. So he gave way to it, as does a tortured beast. He ground his great teeth together, raved, stamped, and swore in barbarous tongues and with barbarous imagery. Even Lady Arabella felt that it was well she was within reach of help, or he might have offered her brutal violence—even have killed her.

"Am I to understand," she said with cold disdain, so much more effective to wound than hot passion, "that you are offering me your love? Your—love?"

For reply he nodded his head. The scorn of her voice, in a sort of baleful hiss, sounded—and felt—like the lash of a whip.

"And you dared! you—a savage—a slave—the basest thing in the world of vermin! Take care! I don't value your worthless life more than I do that of a rat or a spider. Don't let me ever see your hideous face here again, or I shall rid the earth of you."

As she was speaking, she had taken out her revolver and was pointing it at him. In the immediate presence of death his impudence forsook him, and he made a weak effort to justify himself. His speech was short, consisting of single words. To Lady Arabella it sounded mere gibberish, but it was in his own dialect, and meant love, marriage, wife. From the intonation of the words, she guessed, with her woman's quick intuition, at their meaning; but she quite failed to follow, when, becoming more pressing, he continued to urge his suit in a mixture of the grossest animal passion and ridiculous threats. He warned her that he knew she had tried to steal his master's treasure, and that he had caught her in the act. But if she would be his, he would share the treasure with her, and they could live in luxury in the African forests. But if she refused, he would tell his master, who would flog and torture her and then give her to the police, who would kill her.



CHAPTER XIV—BATTLE RENEWED

The consequences of that meeting in the dusk of Diana's Grove were acute and far-reaching, and not only to the two engaged in it. From Oolanga, this might have been expected by anyone who knew the character of the tropical African savage. To such, there are two passions that are inexhaustible and insatiable—vanity and that which they are pleased to call love. Oolanga left the Grove with an absorbing hatred in his heart. His lust and greed were afire, while his vanity had been wounded to the core. Lady Arabella's icy nature was not so deeply stirred, though she was in a seething passion. More than ever she was set upon bringing Edgar Caswall to her feet. The obstacles she had encountered, the insults she had endured, were only as fuel to the purpose of revenge which consumed her.

As she sought her own rooms in Diana's Grove, she went over the whole subject again and again, always finding in the face of Lilla Watford a key to a problem which puzzled her—the problem of a way to turn Caswall's powers—his very existence—to aid her purpose.

When in her boudoir, she wrote a note, taking so much trouble over it that she destroyed, and rewrote, till her dainty waste-basket was half- full of torn sheets of notepaper. When quite satisfied, she copied out the last sheet afresh, and then carefully burned all the spoiled fragments. She put the copied note in an emblazoned envelope, and directed it to Edgar Caswall at Castra Regis. This she sent off by one of her grooms. The letter ran:

"DEAR MR. CASWALL,

"I want to have a chat with you on a subject in which I believe you are interested. Will you kindly call for me one day after lunch—say at three or four o'clock, and we can walk a little way together. Only as far as Mercy Farm, where I want to see Lilla and Mimi Watford. We can take a cup of tea at the Farm. Do not bring your African servant with you, as I am afraid his face frightens the girls. After all, he is not pretty, is he? I have an idea you will be pleased with your visit this time.

"Yours sincerely,

"ARABELLA MARCH."

At half-past three next day, Edgar Caswall called at Diana's Grove. Lady Arabella met him on the roadway outside the gate. She wished to take the servants into her confidence as little as possible. She turned when she saw him coming, and walked beside him towards Mercy Farm, keeping step with him as they walked. When they got near Mercy, she turned and looked around her, expecting to see Oolanga or some sign of him. He was, however, not visible. He had received from his master peremptory orders to keep out of sight—an order for which the African scored a new offence up against her. They found Lilla and Mimi at home and seemingly glad to see them, though both the girls were surprised at the visit coming so soon after the other.

The proceedings were a repetition of the battle of souls of the former visit. On this occasion, however, Edgar Caswall had only the presence of Lady Arabella to support him—Oolanga being absent; but Mimi lacked the support of Adam Salton, which had been of such effective service before. This time the struggle for supremacy of will was longer and more determined. Caswall felt that if he could not achieve supremacy he had better give up the idea, so all his pride was enlisted against Mimi. When they had been waiting for the door to be opened, Lady Arabella, believing in a sudden attack, had said to him in a low voice, which somehow carried conviction:

"This time you should win. Mimi is, after all, only a woman. Show her no mercy. That is weakness. Fight her, beat her, trample on her—kill her if need be. She stands in your way, and I hate her. Never take your eyes off her. Never mind Lilla—she is afraid of you. You are already her master. Mimi will try to make you look at her cousin. There lies defeat. Let nothing take your attention from Mimi, and you will win. If she is overcoming you, take my hand and hold it hard whilst you are looking into her eyes. If she is too strong for you, I shall interfere. I'll make a diversion, and under cover of it you must retire unbeaten, even if not victorious. Hush! they are coming."

The two girls came to the door together. Strange sounds were coming up over the Brow from the west. It was the rustling and crackling of the dry reeds and rushes from the low lands. The season had been an unusually dry one. Also the strong east wind was helping forward enormous flocks of birds, most of them pigeons with white cowls. Not only were their wings whirring, but their cooing was plainly audible. From such a multitude of birds the mass of sound, individually small, assumed the volume of a storm. Surprised at the influx of birds, to which they had been strangers so long, they all looked towards Castra Regis, from whose high tower the great kite had been flying as usual. But even as they looked, the cord broke, and the great kite fell headlong in a series of sweeping dives. Its own weight, and the aerial force opposed to it, which caused it to rise, combined with the strong easterly breeze, had been too much for the great length of cord holding it.

Somehow, the mishap to the kite gave new hope to Mimi. It was as though the side issues had been shorn away, so that the main struggle was thenceforth on simpler lines. She had a feeling in her heart, as though some religious chord had been newly touched. It may, of course, have been that with the renewal of the bird voices a fresh courage, a fresh belief in the good issue of the struggle came too. In the misery of silence, from which they had all suffered for so long, any new train of thought was almost bound to be a boon. As the inrush of birds continued, their wings beating against the crackling rushes, Lady Arabella grew pale, and almost fainted.

"What is that?" she asked suddenly.

To Mimi, born and bred in Siam, the sound was strangely like an exaggeration of the sound produced by a snake-charmer.

Edgar Caswall was the first to recover from the interruption of the falling kite. After a few minutes he seemed to have quite recovered his sang froid, and was able to use his brains to the end which he had in view. Mimi too quickly recovered herself, but from a different cause. With her it was a deep religious conviction that the struggle round her was of the powers of Good and Evil, and that Good was triumphing. The very appearance of the snowy birds, with the cowls of Saint Columba, heightened the impression. With this conviction strong upon her, she continued the strange battle with fresh vigour. She seemed to tower over Caswall, and he to give back before her oncoming. Once again her vigorous passes drove him to the door. He was just going out backward when Lady Arabella, who had been gazing at him with fixed eyes, caught his hand and tried to stop his movement. She was, however, unable to do any good, and so, holding hands, they passed out together. As they did so, the strange music which had so alarmed Lady Arabella suddenly stopped. Instinctively they all looked towards the tower of Castra Regis, and saw that the workmen had refixed the kite, which had risen again and was beginning to float out to its former station.

As they were looking, the door opened and Michael Watford came into the room. By that time all had recovered their self-possession, and there was nothing out of the common to attract his attention. As he came in, seeing inquiring looks all around him, he said:

"The new influx of birds is only the annual migration of pigeons from Africa. I am told that it will soon be over."

The second victory of Mimi Watford made Edgar Caswall more moody than ever. He felt thrown back on himself, and this, added to his absorbing interest in the hope of a victory of his mesmeric powers, became a deep and settled purpose of revenge. The chief object of his animosity was, of course, Mimi, whose will had overcome his, but it was obscured in greater or lesser degree by all who had opposed him. Lilla was next to Mimi in his hate—Lilla, the harmless, tender-hearted, sweet-natured girl, whose heart was so full of love for all things that in it was no room for the passions of ordinary life—whose nature resembled those doves of St. Columba, whose colour she wore, whose appearance she reflected. Adam Salton came next—after a gap; for against him Caswall had no direct animosity. He regarded him as an interference, a difficulty to be got rid of or destroyed. The young Australian had been so discreet that the most he had against him was his knowledge of what had been. Caswall did not understand him, and to such a nature as his, ignorance was a cause of alarm, of dread.

Caswall resumed his habit of watching the great kite straining at its cord, varying his vigils in this way by a further examination of the mysterious treasures of his house, especially Mesmer's chest. He sat much on the roof of the tower, brooding over his thwarted passion. The vast extent of his possessions, visible to him at that altitude, might, one would have thought, have restored some of his complacency. But the very extent of his ownership, thus perpetually brought before him, created a fresh sense of grievance. How was it, he thought, that with so much at command that others wished for, he could not achieve the dearest wishes of his heart?

In this state of intellectual and moral depravity, he found a solace in the renewal of his experiments with the mechanical powers of the kite. For a couple of weeks he did not see Lady Arabella, who was always on the watch for a chance of meeting him; neither did he see the Watford girls, who studiously kept out of his way. Adam Salton simply marked time, keeping ready to deal with anything that might affect his friends. He called at the farm and heard from Mimi of the last battle of wills, but it had only one consequence. He got from Ross several more mongooses, including a second king-cobra-killer, which he generally carried with him in its box whenever he walked out.

Mr. Caswall's experiments with the kite went on successfully. Each day he tried the lifting of greater weight, and it seemed almost as if the machine had a sentience of its own, which was increasing with the obstacles placed before it. All this time the kite hung in the sky at an enormous height. The wind was steadily from the north, so the trend of the kite was to the south. All day long, runners of increasing magnitude were sent up. These were only of paper or thin cardboard, or leather, or other flexible materials. The great height at which the kite hung made a great concave curve in the string, so that as the runners went up they made a flapping sound. If one laid a finger on the string, the sound answered to the flapping of the runner in a sort of hollow intermittent murmur. Edgar Caswall, who was now wholly obsessed by the kite and all belonging to it, found a distinct resemblance between that intermittent rumble and the snake-charming music produced by the pigeons flying through the dry reeds.

One day he made a discovery in Mesmer's chest which he thought he would utilise with regard to the runners. This was a great length of wire, "fine as human hair," coiled round a finely made wheel, which ran to a wondrous distance freely, and as lightly. He tried this on runners, and found it work admirably. Whether the runner was alone, or carried something much more weighty than itself, it worked equally well. Also it was strong enough and light enough to draw back the runner without undue strain. He tried this a good many times successfully, but it was now growing dusk and he found some difficulty in keeping the runner in sight. So he looked for something heavy enough to keep it still. He placed the Egyptian image of Bes on the fine wire, which crossed the wooden ledge which protected it. Then, the darkness growing, he went indoors and forgot all about it.

He had a strange feeling of uneasiness that night—not sleeplessness, for he seemed conscious of being asleep. At daylight he rose, and as usual looked out for the kite. He did not see it in its usual position in the sky, so looked round the points of the compass. He was more than astonished when presently he saw the missing kite struggling as usual against the controlling cord. But it had gone to the further side of the tower, and now hung and strained against the wind to the north. He thought it so strange that he determined to investigate the phenomenon, and to say nothing about it in the meantime.

In his many travels, Edgar Caswall had been accustomed to use the sextant, and was now an expert in the matter. By the aid of this and other instruments, he was able to fix the position of the kite and the point over which it hung. He was startled to find that exactly under it—so far as he could ascertain—was Diana's Grove. He had an inclination to take Lady Arabella into his confidence in the matter, but he thought better of it and wisely refrained. For some reason which he did not try to explain to himself, he was glad of his silence, when, on the following morning, he found, on looking out, that the point over which the kite then hovered was Mercy Farm. When he had verified this with his instruments, he sat before the window of the tower, looking out and thinking. The new locality was more to his liking than the other; but the why of it puzzled him, all the same. He spent the rest of the day in the turret-room, which he did not leave all day. It seemed to him that he was now drawn by forces which he could not control—of which, indeed, he had no knowledge—in directions which he did not understand, and which were without his own volition. In sheer helpless inability to think the problem out satisfactorily, he called up a servant and told him to tell Oolanga that he wanted to see him at once in the turret-room. The answer came back that the African had not been seen since the previous evening.

Caswall was now so irritable that even this small thing upset him. As he was distrait and wanted to talk to somebody, he sent for Simon Chester, who came at once, breathless with hurrying and upset by the unexpected summons. Caswall bade him sit down, and when the old man was in a less uneasy frame of mind, he again asked him if he had ever seen what was in Mesmer's chest or heard it spoken about.

Chester admitted that he had once, in the time of "the then Mr. Edgar," seen the chest open, which, knowing something of its history and guessing more, so upset him that he had fainted. When he recovered, the chest was closed. From that time the then Mr. Edgar had never spoken about it again.

When Caswall asked him to describe what he had seen when the chest was open, he got very agitated, and, despite all his efforts to remain calm, he suddenly went off into a faint. Caswall summoned servants, who applied the usual remedies. Still the old man did not recover. After the lapse of a considerable time, the doctor who had been summoned made his appearance. A glance was sufficient for him to make up his mind. Still, he knelt down by the old man, and made a careful examination. Then he rose to his feet, and in a hushed voice said:

"I grieve to say, sir, that he has passed away."



CHAPTER XV—ON THE TRACK

Those who had seen Edgar Caswall familiarly since his arrival, and had already estimated his cold-blooded nature at something of its true value, were surprised that he took so to heart the death of old Chester. The fact was that not one of them had guessed correctly at his character. They thought, naturally enough, that the concern which he felt was that of a master for a faithful old servant of his family. They little thought that it was merely the selfish expression of his disappointment, that he had thus lost the only remaining clue to an interesting piece of family history—one which was now and would be for ever wrapped in mystery. Caswall knew enough about the life of his ancestor in Paris to wish to know more fully and more thoroughly all that had been. The period covered by that ancestor's life in Paris was one inviting every form of curiosity.

Lady Arabella, who had her own game to play, saw in the metier of sympathetic friend, a series of meetings with the man she wanted to secure. She made the first use of the opportunity the day after old Chester's death; indeed, as soon as the news had filtered in through the back door of Diana's Grove. At that meeting, she played her part so well that even Caswall's cold nature was impressed.

Oolanga was the only one who did not credit her with at least some sense of fine feeling in the matter. In emotional, as in other matters, Oolanga was distinctly a utilitarian, and as he could not understand anyone feeling grief except for his own suffering, pain, or for the loss of money, he could not understand anyone simulating such an emotion except for show intended to deceive. He thought that she had come to Castra Regis again for the opportunity of stealing something, and was determined that on this occasion the chance of pressing his advantage over her should not pass. He felt, therefore, that the occasion was one for extra carefulness in the watching of all that went on. Ever since he had come to the conclusion that Lady Arabella was trying to steal the treasure-chest, he suspected nearly everyone of the same design, and made it a point to watch all suspicious persons and places. As Adam was engaged on his own researches regarding Lady Arabella, it was only natural that there should be some crossing of each other's tracks. This is what did actually happen.

Adam had gone for an early morning survey of the place in which he was interested, taking with him the mongoose in its box. He arrived at the gate of Diana's Grove just as Lady Arabella was preparing to set out for Castra Regis on what she considered her mission of comfort. Seeing Adam from her window going through the shadows of the trees round the gate, she thought that he must be engaged on some purpose similar to her own. So, quickly making her toilet, she quietly left the house, and, taking advantage of every shadow and substance which could hide her, followed him on his walk.

Oolanga, the experienced tracker, followed her, but succeeded in hiding his movements better than she did. He saw that Adam had on his shoulder a mysterious box, which he took to contain something valuable. Seeing that Lady Arabella was secretly following Adam, he was confirmed in this idea. His mind—such as it was—was fixed on her trying to steal, and he credited her at once with making use of this new opportunity.

In his walk, Adam went into the grounds of Castra Regis, and Oolanga saw her follow him with great secrecy. He feared to go closer, as now on both sides of him were enemies who might make discovery. When he realised that Lady Arabella was bound for the Castle, he devoted himself to following her with singleness of purpose. He therefore missed seeing that Adam branched off the track and returned to the high road.

That night Edgar Caswall had slept badly. The tragic occurrence of the day was on his mind, and he kept waking and thinking of it. After an early breakfast, he sat at the open window watching the kite and thinking of many things. From his room he could see all round the neighbourhood, but the two places that interested him most were Mercy Farm and Diana's Grove. At first the movements about those spots were of a humble kind—those that belong to domestic service or agricultural needs—the opening of doors and windows, the sweeping and brushing, and generally the restoration of habitual order.

From his high window—whose height made it a screen from the observation of others—he saw the chain of watchers move into his own grounds, and then presently break up—Adam Salton going one way, and Lady Arabella, followed by the nigger, another. Then Oolanga disappeared amongst the trees; but Caswall could see that he was still watching. Lady Arabella, after looking around her, slipped in by the open door, and he could, of course, see her no longer.

Presently, however, he heard a light tap at his door, then the door opened slowly, and he could see the flash of Lady Arabella's white dress through the opening.



CHAPTER XVI—A VISIT OF SYMPATHY

Caswall was genuinely surprised when he saw Lady Arabella, though he need not have been, after what had already occurred in the same way. The look of surprise on his face was so much greater than Lady Arabella had expected—though she thought she was prepared to meet anything that might occur—that she stood still, in sheer amazement. Cold-blooded as she was and ready for all social emergencies, she was nonplussed how to go on. She was plucky, however, and began to speak at once, although she had not the slightest idea what she was going to say.

"I came to offer you my very warm sympathy with the grief you have so lately experienced."

"My grief? I'm afraid I must be very dull; but I really do not understand."

Already she felt at a disadvantage, and hesitated.

"I mean about the old man who died so suddenly—your old . . . retainer."

Caswall's face relaxed something of its puzzled concentration.

"Oh, he was only a servant; and he had over-stayed his three-score and ten years by something like twenty years. He must have been ninety!"

"Still, as an old servant . . . "

Caswall's words were not so cold as their inflection.

"I never interfere with servants. He was kept on here merely because he had been so long on the premises. I suppose the steward thought it might make him unpopular if the old fellow had been dismissed."

How on earth was she to proceed on such a task as hers if this was the utmost geniality she could expect? So she at once tried another tack—this time a personal one.

"I am sorry I disturbed you. I am really not unconventional—though certainly no slave to convention. Still there are limits . . . it is bad enough to intrude in this way, and I do not know what you can say or think of the time selected, for the intrusion."

After all, Edgar Caswall was a gentleman by custom and habit, so he rose to the occasion.

"I can only say, Lady Arabella, that you are always welcome at any time you may deign to honour my house with your presence."

She smiled at him sweetly.

"Thank you so much. You do put one at ease. My breach of convention makes me glad rather than sorry. I feel that I can open my heart to you about anything."

Forthwith she proceeded to tell him about Oolanga and his strange suspicions of her honesty. Caswall laughed and made her explain all the details. His final comment was enlightening.

"Let me give you a word of advice: If you have the slightest fault to find with that infernal nigger, shoot him at sight. A swelled-headed nigger, with a bee in his bonnet, is one of the worst difficulties in the world to deal with. So better make a clean job of it, and wipe him out at once!"

"But what about the law, Mr. Caswall?"

"Oh, the law doesn't concern itself much about dead niggers. A few more or less do not matter. To my mind it's rather a relief!"

"I'm afraid of you," was her only comment, made with a sweet smile and in a soft voice.

"All right," he said, "let us leave it at that. Anyhow, we shall be rid of one of them!"

"I don't love niggers any more than you do," she replied, "and I suppose one mustn't be too particular where that sort of cleaning up is concerned." Then she changed in voice and manner, and asked genially: "And now tell me, am I forgiven?"

"You are, dear lady—if there is anything to forgive."

As he spoke, seeing that she had moved to go, he came to the door with her, and in the most natural way accompanied her downstairs. He passed through the hall with her and down the avenue. As he went back to the house, she smiled to herself.

"Well, that is all right. I don't think the morning has been altogether thrown away."

And she walked slowly back to Diana's Grove.

Adam Salton followed the line of the Brow, and refreshed his memory as to the various localities. He got home to Lesser Hill just as Sir Nathaniel was beginning lunch. Mr. Salton had gone to Walsall to keep an early appointment; so he was all alone. When the meal was over—seeing in Adam's face that he had something to speak about—he followed into the study and shut the door.

When the two men had lighted their pipes, Sir Nathaniel began.

"I have remembered an interesting fact about Diana's Grove—there is, I have long understood, some strange mystery about that house. It may be of some interest, or it may be trivial, in such a tangled skein as we are trying to unravel."

"Please tell me all you know' or suspect. To begin, then, of what sort is the mystery—physical, mental, moral, historical, scientific, occult? Any kind of hint will help me."

"Quite right. I shall try to tell you what I think; but I have not put my thoughts on the subject in sequence, so you must forgive me if due order is not observed in my narration. I suppose you have seen the house at Diana's Grove?"

"The outside of it; but I have that in my mind's eye, and I can fit into my memory whatever you may mention."

"The house is very old—probably the first house of some sort that stood there was in the time of the Romans. This was probably renewed—perhaps several times at later periods. The house stands, or, rather, used to stand here when Mercia was a kingdom—I do not suppose that the basement can be later than the Norman Conquest. Some years ago, when I was President of the Mercian Archaeological Society, I went all over it very carefully. This was when it was purchased by Captain March. The house had then been done up, so as to be suitable for the bride. The basement is very strong,—almost as strong and as heavy as if it had been intended as a fortress. There are a whole series of rooms deep underground. One of them in particular struck me. The room itself is of considerable size, but the masonry is more than massive. In the middle of the room is a sunk well, built up to floor level and evidently going deep underground. There is no windlass nor any trace of there ever having been any—no rope—nothing. Now, we know that the Romans had wells of immense depth, from which the water was lifted by the 'old rag rope'; that at Woodhull used to be nearly a thousand feet. Here, then, we have simply an enormously deep well-hole. The door of the room was massive, and was fastened with a lock nearly a foot square. It was evidently intended for some kind of protection to someone or something; but no one in those days had ever heard of anyone having been allowed even to see the room. All this is a propos of a suggestion on my part that the well-hole was a way by which the White Worm (whatever it was) went and came. At that time I would have had a search made—even excavation if necessary—at my own expense, but all suggestions were met with a prompt and explicit negative. So, of course, I took no further step in the matter. Then it died out of recollection—even of mine."

"Do you remember, sir," asked Adam, "what was the appearance of the room where the well-hole was? Was there furniture—in fact, any sort of thing in the room?"

"The only thing I remember was a sort of green light—very clouded, very dim—which came up from the well. Not a fixed light, but intermittent and irregular—quite unlike anything I had ever seen."

"Do you remember how you got into the well-room? Was there a separate door from outside, or was there any interior room or passage which opened into it?"
