After a period of thought the girl decided what to do next. She removed the bomb, fuse, green bag—even the satchel—to the big lower drawer of her bureau, and turned the lock.

"No one is likely to come in but the chambermaid, and she will be too busy to disturb anything," Josie decided; and then she locked her room door and went down stairs to breakfast.

CHAPTER XVIII A HINT FEOM ANNIE BOYLE

Josie was late. In the breakfast room she found but one guest besides herself, an old lady with a putty face. But there was also a young girl seated at a near-by table who was grumbling and complaining to the maid who waited upon her.

"It ain't my fault, Miss Annie," protested the maid. "The cook says you ordered your breakfast half an hour ago, an' then went away. We tried to keep it hot for you, and if it's cold it's your own fault."

"I was talking with Mr. Kauffman," pouted the girl, who seemed a mere child. "I've a good notion to order another breakfast."

"If you do, cook will tell your father."

This threat seemed effective. The girl, with a sour face, began eating, and the maid came over to take Josie's order. The tables were near enough for conversation, so when the maid had gone to the kitchen Josie said sweetly:

"That Mr. Kauffman's a nice man, isn't he? I don't wonder you forgot your breakfast. Isn't this Miss Annie Boyle?"

"Yes," was the answer. "Do you know Abe Kauffman?"

"I've met him," said Josie.

"He an' Pa used to be good friends," said Annie Boyle, who did not seem at all shy in conversing with strangers, "but Pa's soured on him lately. I don't know why. P'raps because Abe is a German, an' everybody's tryin' to fling mud at the Germans. But Abe says the German-Americans are the back-bone of this country, and as good citizens as any."

"He don't seem to like the war, though," remarked Josie carelessly.

"Well, do you know why? Abe's had two brothers and five cousins in the German army, and all of 'em's been killed. That's why he's sore on the war. Says his brothers deserved what they got for not comin' to America an' bein' American citizens, like Abe is. But I know he's dreadful sorry 'bout their bein' killed just the same. German folks seem to think a good, deal of their families, an' so jest to mention the war makes Abe rave an' swear."

"That's foolish," said Josie. "He'll get himself into trouble."

"Abe's no fool; he knows how far he can go, an' when to stop talkin'. He'll cuss the war, but you never hear him cuss'n' the United States. He told me, just a while ago, that the war'll make him rich, 'cause he's smart enough to use it for his own good. But he said I mustn't talk about that," she added, with a sudden realization that Josie was regarding her curiously. "Abe an' me's chums, an' what he says is between us. P'raps he was only jokin', 'bout gettin' rich. Abe's a great joker, anyhow."

That this was a rather lame retraction was apparent even to Annie Boyle. She gave Josie a suspicious look, but Josie's face was absolutely expressionless. The maid was placing her order before her and she calmly began her breakfast. A moment later, the old lady rose and tottered out of the room.

"Gee! I wish I had her money," remarked Annie Boyle, looking after her. "She's got a wad of stocks an' just has to cut coupons off 'em. Lives here easy an' don't worry. If I had her dough I'd—" She stopped suddenly.

"Money's a good thing to have," said Josie. "There's Tom Linnet, now; he's going to buy a cigar store."

"How'd you know?" asked Annie quickly.

"Why, he told me."

"Oh; are you an' Tom friends?"

"We're not enemies. Tom's in luck to have so much money."

"Wall," said Annie, "he's a fool to flash it all of a sudden. Pa took him for night clerk when he didn't have a cent—and it wasn't so long ago, either. He gets his board an' five dollars a week. Folks are goin' to wonder where he got all his fine clothes, an' them di'monds, an' how he can afford to buy Barker's cigar store. I asked Abe about it an' Abe says he guesses Tom got the money from an aunt that jus' died."

"Perhaps he did."

"Well, where'd he get the aunt? Tom's got two brothers that are peddlers an' a father who's a track-walker, an' he's got a mother what takes in washin'. If there's an aunt, she's some relation to the rest of the family, so why didn't she leave them some money, as well as Tom?"

"I don't know, but I'm glad Tom is so well fixed," answered Josie, rather absently, for her eye had fallen on the menu card beside her plate, and the menu card had somehow conveyed a new thought to her mind. She picked it up and examined it critically. Part of it was printed in a queer, open-faced type—all capitals—while the balance of the list of dishes had been written in with pen and ink. These printed bills would do for a good many breakfasts, for they mentioned only the staples, while the supplementary dishes were day by day added in writing.

"I wonder who prints your bills-of-fare?" she said to Annie Boyle.

"Why do you wonder that?" demanded Annie.

"I like the type, and I want to get some cards printed from it."

"We print our own bills," said the child. "There's a press an' type an' the fixings in a room in the basement, an' Tom Linnet used to print a new card every day for all the three meals. He did it at night, you know, between two an' six o'clock, when nobody's ever around the hotel. They was swell bills-of-fare, but Tom claimed he couldn't do so much printin', although that's part o' the night clerk's duty, an' Pa thought it used up too much good cardboard at war-time prices. So now we jus' get out a new bill once a week, an' write the extry dishes on it."

"That does very well," said Josie. "Does Tom still do the printing?"

"Yes. Pa hired him as night clerk 'cause he'd worked in a printin' office an' could do printin'. But since Tom got rich he don't like to work, an the bills ain't printed as good as they used to be."

"This looks pretty good to me," said Josie, eyeing it approvingly.

"I guess, if Tom wasn't goin' to leave, Pa would fire him," asserted Annie, rising from the table. "Good mornin', miss; I'll see you again, if you're stoppin' here."

After she had gone, Josie finished her breakfast thoughtfully. Three distinct facts she had gleaned from Annie Boyle's careless remarks. First, Tom Linnet had acquired sudden riches. Second, the type used on the hotel menu cards was identically the same that the disloyal circulars had been printed from. Third, between the hours of two and five in the mornings, the night clerk's duties permitted him to be absent from the hotel office.

Josie decided that Annie Boyle had not been admitted to the inner confidences of the conspirators, and that Tom Linnet was their tool and had been richly paid for whatever services he had performed. She was now gathering "clues" so fast that it made her head swim. "That chance meeting with Kauffman, at Kasker's," she told herself, "led me directly into the nest of traitors. I'm in luck. Not that I'm especially clever, but because they're so astonishingly reckless. That's usually the way with criminals; they close every loop-hole but the easiest one to peep through—and then imagine they're safe from discovery!"

CHAPTER XIX THE PRINTING OFFICE

After breakfast Josie sallied out upon the street and found a hardware store. There, after some exploration, she purchased an asbestos table-mat. With this she returned to her room and locked herself in.

The chambermaid had "been and gone," but Josie's drawer was still locked and its precious contents intact. The girl scraped the surface of the table-mat with her pen-knife until she had secured enough loose fibre to serve her purpose and then she proceeded to restuff the fuse with the asbestos fibre the entire length of the section from which she had removed the powder. Then she pushed the end of the fuse into the hole in the bomb, wired it as before, and replaced the long fuse in its grooves.

"Now," said Josie, surveying her work with satisfaction, "if they light that fuse, and expect it to explode the bomb in an hour or more, they'll be badly fooled. Also, I shall have prevented another catastrophe like the explosion at the airplane factory."

She replaced the bomb in its bag, placed the bag in the black satchel, tucked in the soiled shirts to cover it and with her improvised key managed to relock the satchel. Watching for a time when the corridor was vacant, she went to 45, entered the room and replaced the satchel on its shelf, taking care to arrange the newspaper before it as a mask.

She had taken the chair from the closet and was about to leave the room when she heard footsteps coming down the hallway, accompanied by a whistle which she promptly recognized.

"Caught!" she exclaimed, and gave a hurried glance around her. To hide within the room was impossible, but the window was open and the iron fire-escape within easy reach. In an instant she had mounted it and seizing the rounds of the iron ladder climbed upward until she had nearly reached the next window directly above, on the third floor. Then she paused, clinging, to get her breath.

Kauffman was annoyed to find the door of his room unlocked. He paused a moment in the middle of the room and looked around him. "Confound that chambermaid!" Josie heard him mutter, and then he opened the closet door and looked in. Apparently reassured, he approached the open window, stuck out his head and looked down the fire-escape. Josie's heart gave a bound; but Kauffman didn't look upward. He drew in his head, resumed his whistling and busied himself repacking the sample suspenders in his suitcase.

Josie hoped he would soon go out again, but he seemed to have no intention of doing so. So she climbed her ladder until she could look into the window above, which was also open. The old lady she had seen at breakfast was lying upon the bed, her eyes closed. Josie wondered if she was asleep. The door leading from the room to the hallway also stood open. The weather was warm, and the old lady evidently wanted plenty of air.

While Josie hesitated what to do a boy came up the alley, noticed her on the fire-escape and paused to look at her in astonishment. The girl couldn't blame him for being interested, for her attitude was certainly extraordinary. Others were likely to discover her, too, and might suspect her of burglary and raise a hue and cry. So she deliberately entered the room, tiptoed across to the hall and escaped without arousing the old lady. But it was a desperate chance and she breathed easier when she had found the stairs and descended to her own floor. Safe in her own room she gave a little laugh at her recent predicament and then sat down to note her latest discoveries on her tablets.

Josie O'Gorman was very particular in this regard. Details seemingly of trifling moment but which may prove important are likely to escape one's memory. Her habit was to note every point of progress in a case and often review every point from the beginning, fitting them into their proper places and giving each its due importance. A digest of such information enabled her to proceed to the next logical step in her investigation.

"These items all dovetail very nicely," she decided, with a satisfied nod at the quaint characters on the tablets—which all the world might read and be no wiser. "I must, however, satisfy myself that Tom Linnet actually printed those circulars. The evidence at hand indicates that he did, but I want positive proof. Also, I'd like to know which one of the gang employed him—and paid him so liberally. However, that suggestion opens up a new line of conjecture; I don't believe Tom Linnet got all his wealth merely for printing a few circulars, helping to address them, and keeping his mouth shut. But—what else has he been paid for?"

She brooded on this for a while and then determined to take one thing at a time and follow it to a conclusion. So she once more quitted her room and descended by the elevator—openly, this time—to the office. It was now noon and the hotel office was filled with guests, and the clerks and bellboys were all busily occupied. Josie wandered carelessly around until she found the stairway leading to the basement. Watching her opportunity she slipped down the stairs.

The basement was not as barren as she expected to find it. There was an open central space, on one side of which were rooms for the barber shop, baths, and a pool room, all more or less occupied by guests and attendants. On the opposite side, at the rear, were baggage and storerooms. Just beside her she noted a boot-black's stand, where a colored boy listlessly waited for customers.

"Shine, miss?" he inquired.

"No," said Josie in a businesslike tone; "I'm looking for the printing office."

"Secon' door, miss," indicating it with a gesture; "but dey ain't nobody dere. De room's mos'ly kep' locked."

"I know," said Josie, and advancing to the door drew out her keys.

Her very boldness disarmed suspicion; the boy was not sufficiently interested to watch her, for a man came out of the barber-shop and seated himself in the boot-black's chair.

This sort of lock didn't phase Josie at all. At the second trial she opened the door, walked in and closed the door behind her.

It was a small room, dimly lighted and very disorderly. Scraps of paper were strewn around the floor. Dust had settled on the ink-rollers of the foot-press. A single case of type stood on a rack and the form of a bill-of-fare—partly "pied"—was on a marble slab which formed the top of a small table. On an upturned soap-box was a pile of unprinted menu cards. Josie noted a few cans of ink, a bottle of benzine, and a few printing tools lying carelessly about, but the room contained nothing more.

Having "sized up" Tom Linnet's printing room with one swift glance, the girl stooped down and began searching among the scraps that littered the floor. They were mostly torn bits of cardboard or crumpled papers on which trial impressions had been made.

Josie expected momentarily to be interrupted, so she conducted her search as rapidly as was consistent with thoroughness. She paid no attention to the card scraps but all papers she smoothed out, one by one. Finally, with a little cry of triumph, she thrust one of these into her handbag. She made this discovery just back of the press, and glancing up, she noted a hook that had formerly been hidden from her view, on which were impaled a number of papers—the chef's "copy" from which various bills had been printed. Running through these papers she suddenly paused, pulled one away from the hook and tucked it into her bag.

She was fairly satisfied, now, but still continued her search amongst the litter. It was not easy to decipher writing or printing in that dim light, but her eyes were good and the longer she remained in the room the more distinctly she saw. There was an electric globe suspended over the press, but she dared not turn on the light for fear of attracting attention. Several scraps on which writing appeared she secured without trying to read them, but presently she decided she had made as thorough an examination of the place as was necessary.

She left the room, locked the door again and boldly mounted the stairs to the office, meeting and passing several men who scarcely noticed her. Then she took the elevator to her room and washed her grimy hands and prepared for luncheon.

At the table she slipped another of the printed bills into her bag, to use for comparison, and afterward ate her lunch as calmly as if she were not inwardly elated at the success of her morning's work. Josie felt, indeed, that she had secured the proof necessary to confound the traitors and bring them to the bar of justice. But there might be other interesting developments; her trap was still set. "There's no hurry," she told herself. "Let's see this thing through—to the end."

Indeed, on reflection, she realized that several threads of evidence had not yet been followed to their source. Some points of mystification still remained to be cleared up. Her facts were mingled with theories, and she had been taught that theories are mighty uncertain things.

On leaving the dining room, Josie got on her hat and jacket, went out to the street and caught an Oak Avenue car.

"Oh, Josie!" cried a well-known voice, and there sat Mary Louise, on her way home from the Shop.

Josie gave her a haughty look, walked straight to the far end of the car and sat down in a vacant seat. The car was half filled with passengers.

Mary Louise pushed forward and sat beside her friend. Josie stared straight ahead, stolidly.

"No one here knows you," whispered Mary Louise, "won't you speak to me, Josie?"

No reply.

"Where are you stopping? What are you doing? How are you getting along on the case?" pleaded Mary Louise, so softly that no one else could overhear.

Josie maintained silence. Her features were expressionless.

"I know you told me, in case we met, not to recognize you," continued Mary Louise, "but I'm so anxious for news, dear! Can't you come home, to-night, and have a good talk with me? You owe me that much consideration. Josie."

The car stopped at a street intersection. Josie stood up.

"Not to-night," she replied, and alighted from the car just as it started to move again.

"Bother Mary Louise!" she muttered, "she has made me walk three whole blocks."

Mary Louise was human and she was provoked. There was really no need for Josie O'Gorman to be so absurdly mysterious. Had she not known her so well, Mary Louise would have felt that Josie had deliberately insulted her. As it was, she blamed her friend for inexcusable affectation. "I'm not sure," she reflected, "that a girl can be a detective—a regular detective—without spoiling her disposition or losing to some an extent her maidenly modesty. Of course, Josie has been brought up in an atmosphere of mystery and can't be blamed for her peculiarities, but—-I'm glad I'm not a detective's daughter."

Josie, however, wasn't worrying over any resentment her friend might feel at the necessary snub. She was on a keen scent and already had forgotten her meeting with Mary Louise. Three blocks farther on she turned into the walk leading to an old but picturesque residence, at one time a "show place" of Dorfield and the pride of the Dudley-Markhams, but now overshadowed by modern and more imposing mansions.

Josie rang the door-bell and presently the door was opened by a young and rather untidy maid.

"I'd like to see Professor Dyer," said Josie.

"He's gone to Washington," was the reply.

"Indeed! Are you quite sure?"

"Yes," said the maid; and then Mrs. Dyer's head appeared in the opening and she gave Josie a curious if comprehensive examination. Then:

"If you're from one of the schools, I'm sorry to tell you that Professor Dyer went to Washington by the early train this morning. I don't know how soon he will be back. Professor Harrington of the High School is in charge. But perhaps it is something I can do?"

"No, thank you; I can wait," said Josie, and went away.

"So," she said to herself, as she made her way back to town in a street car, "if Dyer has really gone to Washington, he hopes to get possession of the old desk and its hidden papers. Pretty important to him, those papers are, and I wouldn't blame him for chasing them up. But—has he really gone? Mrs. Dyer thinks so; but all evidence points to the fact that she's not in her husband's confidence. Now, if Dyer is on his way to Washington, what did last night's secret meeting mean? His absence will complicate matters, I fear. Anyhow, I must revise my conclusions a bit."

CHAPTER XX ONE GIRL'S WITS

As she entered the hotel Josie encountered Joe Langley, the one-armed soldier back from the war. She had taken a great interest in this young fellow and admired his simple, manly nature, having had several interesting conversations with him at the Liberty Girls' Shop and at the drills. Josie felt she needed an ally at this juncture, and here was one who could be trusted.

"Joe," she said earnestly, drawing him aside, "are you going to be busy this evening?"

"Yes, Miss O'Gorman, I'm busy every evening now," he replied. "I've taken a job, you know, and my loafing days and social stunts are over. There wasn't any bread-an'-butter in telling the society dames about my war experiences, so I had to go to work. I'm night watchman at the steel works, and go on duty at seven o'clock."

Josie was disappointed. Looking at him musingly, she asked:

"Are they making munitions now, at the steel works?"

"Of course; it's practically under government control, they say, but is still operated by the old company. They make shells for the big guns, you know, and they've ten car-loads on hand, just now, ready to be shipped to-morrow."

Josie drew a long breath. This was real news and her active mind jumped to a quick conclusion.

"Are the shells loaded, Joe?" she inquired.

"All ready for war," replied the soldier. "You see, a night watchman in such a place has an important position. I guard those shells by night, and another man does nothing but guard them by day."

"Where are they stored?" was Josie's next question.

"In the room just back of Mr. Colton's office—the big main building."

"So Mr. Colton is still the head of the company?"

"He's Vice-President and General Manager, and he knows the steel and ammunition business from A to Z," asserted Joe Langley. "Mr. Colton represents the government as well as the steel works. The President is Mr. Jaswell, the banker, but he doesn't do anything but attend the Board meetings."

"Joe," said Josie impressively, "you know who I am, don't you?"

"Why, you're one of the Liberty Girls, I guess."

"I'm from Washington," she said. "My father, John O'Gorman, is one of the government's secret service officers; I'm working on a case here in the interests of our government, and I may want you to help me foil a German spy plot."

"Count on me!" said Sergeant Joe, emphatically. And then he added: "I'd like to make sure, though, that you're really what you claim to be."

Josie opened her hand bag and from a side pocket drew a silver badge engraved "U. S. Secret Service. No. L2O1." That was her father's number and a complimentary badge, but Joe was satisfied. He had to glance inside the handbag to see it, for the girl dared not exhibit it more openly.

"If you want to know more about me, ask Colonel Hathaway," continued Josie.

"No," said Joe; "I believe you're on the square. But I'd never have suspected it of you. Tell me what I'm to do."

"Nothing, at present. But should a crisis arrive, stand by me and obey my instructions."

"I'll do that," promised the man.

When the girl had regained her room in the hotel, she sat down with a businesslike air and wrote upon a sheet of paper, in her peculiar cypher, the story of her discoveries and the conclusions they justified up to the present hour. This was to fix all facts firmly in her mind and to enable her to judge their merits. The story was concise enough, and perhaps Josie was quite unaware how much she had drawn upon her imagination. It read this way:

"Disloyal circulars have been issued from time to time in Dorfield, designed to interfere with sales' of Liberty Bonds, to cause resentment at conscription and to arouse antipathy for our stalwart allies, the English. These circulars were written by John Dyer, superintendent of schools, who poses as a patriot. The circulars were printed in the basement of the Mansion House by Tom Linnet, a night clerk, who was well paid for his work. Papers found secreted in an old desk from the attic of Dyer's house prove that Dyer is in the pay of German agents in this country and has received fabulous sums for his 'services,' said services not being specified in the documents. In addition to these payments, there were found in the desk notes of the Imperial German Government, for large amounts, such notes to be paid 'after the war.'

"Dyer is clearly the head of the German spy plot in Dorfield, but the person who acts as medium between Dyer and the Master Spy is an alleged suspender salesman calling himself Abe Kauffman. This Kauffman makes frequent trips to Dorfield, giving orders to Dyer, and on one occasion Kauffman, who stops at the Mansion House while in town, hired Tom Linnet to place a bomb in the Airplane Factory, causing an explosion which destroyed many government airplanes and killed several employees. The sum paid Linnet for this dastardly act has made him rich and he has bought or is about to buy a cigar store. Kauffman now has another bomb in his possession, doubtless brought here to be placed, when opportunity arrives, to do the most possible damage. Indications are that he may attempt to blow up the steel works, where a large amount of shells are now completed and ready for shipment to-morrow—meaning that the job must be done to-night, if at all. Perhaps Linnet will place the bomb; perhaps Kauffman will do it himself. Dyer has lost his incriminating papers and notes and is on his way to Washington in an endeavor to recover them.

"Associated with Dyer in his horrible activities is Mrs. Augusta Charleworth, occupying a high social position, but of German birth and therefore a German sympathizer. She is clever, and her brains supplement those of Dyer, who seems more shrewd than initiative, being content to execute the orders of others. Dyer was educated at Heidelburg, in Germany, which accounts, perhaps, for his being pro-German, although I suspect he is pro-anything that will pay him money. Dyer and the Hon. Andrew Duncan, while political pals, are not connected in this spy plot, but I suspect that Peter Boyle, the proprietor of the Mansion House may be one of the gang. I've no evidence yet that implicates Boyle, but he harbors Kauffman as a guest and ought to know that his night clerk is printing traitorous propaganda. So far, the evidence incriminates Kauffman, Mrs. Charleworth, Dyer and Tom Linnet. I believe Mrs. Dyer to be innocent of any knowledge of her husband's crimes; otherwise, she would never have parted with that important desk—the desk that will prove his ruin and ought to cost him his life.

"My plan is this," concluded the notation, "to catch Kauffman or Linnet in the act of placing the bomb to-night, make the arrest, round up the other guilty ones and jail them, and then turn the case over to the federal officers for prosecution. A telegram to Washington will secure Professor Dyer's arrest on his arrival there."

Josie read this through twice and nodded her red head with intense satisfaction.

"All clear as crystal," she asserted gleefully. "I have proof of every statement, and the finale can't go very wrong with such knowledge in my possession. To-night, unless all signs fail, will prove a warm night— warm enough to scorch these dreadful, murderous tools of the Kaiser!"

And now Josie skipped over to the police station and had a somewhat lengthy conference with Chief Farnum, who knew her father and treated the girl detective with professional consideration. After this she hunted up the two government agents—old Jim Crissey and young Norman Addison—who knew her well as "John O'Gorman's clever kid, the pride of her doting Daddy." They listened to her with interest and genuine respect for her talent and not only promised their assistance whenever it might be needed but congratulated her warmly on her good work.

This concluded Josie's afternoon labors, and it was with a sense of triumphant elation that she returned to her hotel to rest and prepare for the expected crisis.

CHAPTER XXI SURPRISES

Josie went to dinner as soon as the dining room opened. When she came out she met Abe Kauffman going in. He stopped and spoke to her.

"Sell any brains yet?" in a jocular way.

"Not to-day," she replied, with her innocent, baby-like stare.

"Well, I didn't sell any suspenders, either. There are no spenders for suspenders. Ha, ha, ha!"

"That doesn't seem to worry you much," asserted Josie, pointedly.

He gave a shrug.

"Well, to-morrow morning I leave by the 5:30 train east, so if I don't see you any more, I hope the brains will find a market."

"Thank you."

She went on, glad to escape the man. "He told me about leaving on the 5:30, and is probably giving everyone else the same information, so he can't be connected with the explosion," she reflected. "Clever Mr. Kauffman! But not clever enough to realize he is near the end of his infamous career."

Josie's plans, perfected during that afternoon, primarily involved the shadowing of Abe Kauffman every moment, from now on. Abe Kauffman and his black satchel. For it grew dark early at this time of year, and already the brief twilight was fading. So the girl hastened to her room and exchanged her gray walking suit for a darker one that was inconspicuous and allowed free movement. Then she slipped her little pearl-mounted revolver—her father's gift—into her handbag and decided she was ready for any emergency.

Having extinguished the light in her room, she glanced from the window into the alley below, where the shadows were now gathering deeply.

"I think Kauffman will go down the fire-escape and drop into the alley," she mused; "but he must first come to his room for the black satchel, in any event, and from that instant I must never lose sight of him."

Suddenly she discovered a form pacing slowly up and down the otherwise deserted alley. Fearful that other detectives were on the watch, and might disrupt her plans, she strained her eyes to discover this person's identity. There was but one light to relieve the gloom, and that was far down the alley, a spot the prowler for some time avoided. Finally, however, he came to a point where the light touched his face and Josie instantly recognized Tom Linnet.

"He is waiting for someone," she decided, "and Kauffman is still at dinner—killing time because it's yet too early to undertake his nefarious task. Tom Linnet may be the tool he has selected, and I ought to get in touch with the boy, somehow, before he meets the arch conspirator. Kauffman is the one I prefer to land."

With this in mind, she hurried down, passed out at the front office doorway and turned into a narrow drive at the south of the hotel, which led to the rear alley. A great business block, now dark and deserted, loomed on the other side of the driveway, which was used by the baggage and supply wagons in the daytime.

When the girl reached the corner of the alley she found herself in very deep shadow; so she ventured to protrude her head far enough to look after Tom Linnet. To her surprise the party he had been waiting for had already joined him, for she discovered two dusky forms pacing the alley.

It could not be Kauffman. While she hesitated whether to steal closer or maintain her position, the two advanced almost to her corner and paused there—in the blackest spot they could find.

"I tell you I won't do it!" said Tom, in a hard, dogged tone that was tense with excitement. "I'm through, and that's all there is to it."

"That's a mistaken notion," was the quiet reply. "You're too deep in the plot to draw back, and the pay is well worth while."

"I don't want any more money," growled Tom.

"You'll get two thousand for this night's work. Cash. And there is no risk; you know that."

"Risk? God, man! Can't you guess how I dream of those poor devils I sent to their death in the airplane job? I hate the money I got! I—I—"

"See here," said the other voice impatiently, "that was a mistake, and you know it. We didn't intend murder, but the explosion was delayed. No one will get hurt to-night."

"Not through me," declared Tom.

"If you fail us, you'll come to grief."

"If I come to grief, so will you. Peach on me, and I'll blow the whole deal." There was a moment's silence.

"Would three thousand satisfy you?" demanded the tempter.

"No," asserted Tom stoutly; "I'm goin' to quit. What's done can't be undone, but I'm through with you. It—it's too blamed terrible, that's what it is! Leave me alone an' let me turn honest. Why don't you do the job yourself?"

"I think I will," said the other calmly. "If you intend to turn down a good thing, I'll do my own work and save the money. But remember, Linnet, silence is your only salvation. Don't talk at all; if you do, you're liable to say the wrong thing—and you can't afford to do that."

"I'm no fool," responded the night clerk, a shade of relief in his tone. "But don't come to me again, Professor. I'm done with you."

Professor! Josie felt a distinct shock. She had to flatten herself against the wall, too, and remain rigid, for the man abruptly turned the corner and marched down the driveway. Half way to the brilliantly lighted street he dodged behind the building opposite the hotel, threading his way through narrow back yards. Josie followed, swift and silent. Finally they reached a place where the man was forced to pass beneath the rays of a lamp and Josie was near enough to see his face. It was, in reality, Professor John Dyer.

That assurance was all the girl wanted, just now. She let him go his way and turned to regain the hotel. It was not quite eight o'clock, yet she felt it important to keep an eye on Kauffman and the bomb. The bomb, especially, for until Dyer took possession of the infernal contrivance he could do no mischief.

In the hotel lobby she entered a public telephone booth and called up Jim Crissey; then she went straight to her room. She could hear a low whistling in 45, which informed her that Kauffman had not yet gone out and that he was in a cheerful mood.

"I'm beginning to understand their method of work," Josie reflected. "Kauffman prepares the bombs, or brings them here under the guise of a suspender salesman; Dyer arranges for their being placed, having secured information as to where an explosion will do the most damage to the government, and Tom Linnet is used as the tool to do the actual work. Mrs. Charleworth probably assists Dyer in getting special information, and advises the gang, but doesn't take an active part in the perpetration of the crimes. Her brains and position would naturally place her at the head of the conspirators in Dorfield, although I'm pretty sure Kauffman, as the agent of the Master Spy, can dictate what they must do."

Kauffman slammed his door and locked it. He was going out. Josie opened her own door a crack to look after him. He was walking deliberately down the corridor, openly carrying in his left hand the black satchel.

To Josie this seemed the essence of effrontery. He had no intention of using the fire-escape, after all. He trusted in bravado, as so many careless criminals do. As she stealthily followed him, she observed the man stop in the office and exchange commonplaces with one or two guests whom he knew.

In reality, this was his safest plan. The black bag did not look suspicious. Presently the bomb would be turned over to Dyer and Kauffman's responsibility would then end. His very boldness was calculated to prevent suspicion.

Leaving the hotel, Kauffman walked leisurely up the lighted street. Only when he turned a corner did Josie momentarily lose sight of him. There were many pedestrians at this hour and they masked the girl's form and for a while enabled her to keep near to the man she was shadowing. The only thing that puzzled Josie was the fact that Kauffman was proceeding in a direction exactly opposite that taken by Dyer a short time before. Dyer went south and Kauffman was going north.

When the business section of Dorfield was passed, the streets became more deserted. They were not well lighted either, which favored Josie the more.

Kauffman kept steadily on, and as the houses along the way thinned, Josie decided he was headed directly for the steel works. That upset her calculations a bit, for she knew he had not seen Dyer since the latter's interview with Tom Linnet, nor had he seen Linnet; therefore he could not know that any arrangements he had previously made with them had fallen through. The German's present actions, however, indicated that he had decided to place the bomb himself, without the assistance of his fellow conspirators. Had he been warned of Linnet's defection? Had he means of communicating with Dyer unknown to Josie? Dyer was a mystery; even his wife believed he was now on his way to Washington.

Surprises, in Josie's line of work were not uncommon, and this was no time to consider whys and wherefores. The one thing she was sure of was that the bomb was in the black satchel and the black satchel in Kauffman's hand. No matter where the other conspirators might be or how they were implicated in tonight's plot, as long as she kept her eye on the bomb, she would be able to control the situation.

CHAPTER XXII A SLIGHT MISTAKE

From the edge of the town to the steel works the road led through a common, overgrown with brush and weeds. There was no moon and although the distance was not great it was a lonely, dark and "creepy" place. As soon as the girl saw Kauffman take the road to the works she decided to get there before he could do so. Knowing well she could not be seen, she branched off through the brush, and finding her way by instinct rather than sight, ran swiftly in a half circle over the fields and struck the road again considerably in advance of the more deliberate Kauffman.

She now set off at her swiftest run and on reaching the manager's office, in the front of the main building, perceived that it was lighted.

Josie rapped upon the door and it was opened by one-armed Joe Langley, the night watchman.

"Quick!" she said, "let me in and hide me somewhere, where I can't be seen."

Joe pulled her in, closed the outer door and locked it, and then faced her.

"What's up?" he demanded.

"There's a man coming here with a bomb in a black satchel," she panted. "He intends to blow up this building, in which all the shells axe stored. I want to catch him in the act, Joe, and you must hide me somewhere."

Joe glanced around with a puzzled look.

"Where?" he asked helplessly.

So Josie looked around her, too. This end of the long building was partitioned off for offices, as it fronted the town. The central section was a big space containing a table, benches, etc., while on either side were little glass rooms with partitions between them reaching about seven feet in height, the ceiling being some twelve feet from the floor. The first room to the left of the entrance was marked "Manager" on its glass door; the next office "Purchasing Agent," and the third "Chief Engineer." On the right hand side, the corresponding offices were marked "Secretary," "Examiner," and "Superintendent." All the office doors were locked except that of the Purchasing Agent, which stood ajar. Josie sprang into that office and cast a hurried glance around. The glass division between that and the manager's office was "frosted" with white paint, but so carelessly done that she found places where she could see through into the office of the manager. Also she could see into the main, or reception room, even with her door closed.

While she examined this place a knock came on the outer door—a loud, imperative knock.

"This will do," whispered Josie to Joe. "Go an let him in, but don't let him suspect I'm here."

Joe was not quick-witted, but on the battlefields of France he had learned prompt obedience to orders. Josie, as a government agent, was now his commander, so he merely nodded to her as he walked over to unlock the outer door.

Kauffman stepped in, satchel in hand.

"You're the watchman, I suppose," he said cheerfully. "Is Mr. Colton here?"

"No," answered Joe.

"I was to meet him here at this time," said Kauffman.

"He said he'd be back this evening," returned Joe, just recalling that fact, "but he isn't here yet."

"All right," said the man, "I'll wait."

He carefully placed the satchel on the table and sat down on a bench. Joe regarded him suspiciously, remembering the girl's warning, but said nothing more. Josie was watching Kauffman from her retreat, but as her little office was dark and the German sat under a bright light it was impossible for him to know that his every movement was under observation.

The minutes dragged. A big clock on the wall ticked with an ominous sound. Kauffman drew out his watch and compared it with the clock. He appeared to grow restless.

Josie's quick ears caught the distant sound of a motor car coming down the road. Perhaps Kauffman heard it also. He rose from his seat and going to the table unlocked the black satchel, pressed the top open and looked inside it. Still bending over the satchel he placed a cigarette in his mouth, lighted a match and applied the flame to his cigarette. His back was toward Josie but she comprehended instantly the action.

"He has lighted the fuse!" she murmured, triumphantly.

The motor car came to a sudden halt outside the door, which Joe had left unlocked; but while the German turned expectantly toward the door the maimed soldier, hearing Josie's whisper, approached her little room and slightly opened her door.

"He has lighted the fuse of the bomb," she said to him excitedly. "The bomb is in the satchel!"

Joe turned quickly to the table. He dived into the bag with his one good hand, drew out the heavy ball of steel and rushed with it to the door just as the manager, Mr. Colton, opened it and stepped in.

So swift were Joe's actions that Kauffman had no time to interfere. Both he and the manager stared in amazement as Joe Langley rushed outside and with all his might hurled the bomb far out upon the common.

"Confound you!" cried Kauffman. "What did you do that for?"

"What is it?" inquired the astonished manager.

"A bomb!" cried Josie, stepping from her retreat and confronting them. "A bomb with the fuse lighted, and timed to blow up this building after you had gone away, Mr. Colton. That man before you is a German spy, and I arrest him in the name of the law. Put up your hands, Abe Kauffman!"

The little revolver was in her hand, steadily covering him. Kauffman gave an amused laugh, but he slowly raised his arms, as commanded.

"I don't quite understand," said the puzzled manager, looking from one to the other.

"Well, I brought the new projectile, Colton, as I had agreed," answered the German, coolly, "but your quaint watchman has thrown it away. As for the girl," he added, with a broad grin, "she has fooled me. She said she had brains, and I find she was mistaken."

The manager turned to Josie.

"May I ask who you are, Miss, and how you came to be in my office?"

"I am Josie O'Gorman, an agent of the government secret service," she replied, not quite truthfully. "I've been shadowing this man for some time. I tell you, sir, he brought a bomb here, to destroy this building, and under pretense of lighting, a cigarette he has just lighted the time fuse. The bomb was in that satchel, but—" she added impressively, "as a matter of fact the thing was harmless, as I had already removed the powder from the fuse."

Kauffman gave a low whistle.

"How did you manage that?" he asked curiously.

"Never mind how," she retorted; "I did it."

Kauffman turned to the manager.

"Will you please order your man to get the projectile?" he asked. "It is lucky for us all that the thing isn't loaded, or there really would have been an explosion." He now turned to Josie, with his hands still in the air, and explained: "It is meant to explode through impact, and ordering it tossed out there was the most dangerous thing you could have done."

At the manager's command Joe took an electric searchlight and went out to find the steel ball.

"If you please, miss," said Kauffman, "may I put down my arms? They are tired, and I assure you I will not try to escape."

Josie lowered the revolver. Her face was red. She was beginning to wonder if she had bungled the case. A second thought, however—a thought of the papers she had found in the old desk—reassured her. She might have been wrong in some respects, but surely she was right in the main.

"This man," said Mr. Colton, pointing to Kauffman, "is known to me as a munition expert. He bears the endorsement of the Secretary of War and is the inventor of the most effective shells we now manufacture. What you have mistaken for a bomb is his latest design of projectile for an eight-inch gun. He had arranged to bring it here and explain to me its mechanism to-night, and also to submit a proposition giving our company the control of its manufacture. If you are a government agent, you surely understand that these arrangements must be conducted with great secrecy. If we purchase the right to make this projectile, we must first induce the government to use it, by demonstrating its effectiveness, and then secure our contracts. So your interference, at this time, is—-ahem!—annoying."

Josie's face was a little more red than before. A second motor car drew up at the door and to her astonishment Mrs. Charleworth entered and greeted both the manager and Kauffman in her usual charming manner. Then she looked inquiringly at the girl.

"Pardon me, madam," said Mr. Colton. "There has been a singular misunderstanding, it seems, and our friend here has been accused of being a German spy by this young lady, who is a government detective— or—or claims to be such. The precious projectile, in which you are so deeply interested, has just been tossed out upon the common, but Joe Langley is searching for it."

Mrs. Charleworth's face wore an amused smile.

"We are so beset with spies, on every hand, that such an error is quite likely to occur," said she. "I recognize this young lady as a friend of the Hathaway family, and I have met her at the Liberty Girls' Shop, so she is doubtless sincere—if misled. Let us hope we can convince her— Miss O'Gorman, isn't it?—that we are wholly innocent of attempting to promote the Kaiser's interests."

Joe came in with the steel ball, which he deposited upon the table. Then, at a nod from the manager, the soldier took his searchlight and departed through the door leading to the big room in the rear. It was time to make his regular rounds of the works, and perhaps Mr. Colton preferred no listeners to the conversation that might follow.

CHAPTER XXIII THE FLASHLIGHT

"Perhaps," said Josie, her voice trembling a little, "I have assumed too much, and accused this man," pointing to Kauffman, "unjustly. I was trying to serve my country. But I am somewhat confused, even yet, in regard to this affair. Will you please tell me, Mrs. Charleworth, what connection you have with Mr. Kauffman, or with his—projectile?"

"Very gladly," said the lady, graciously. "I am a stockholder in this steel company—a rather important stockholder, I believe—and while I am not a member of the board of directors, Mr. Colton represents my interests. Two years ago we bought the Kauffman shell, and paid liberally for it, but Mr. Kauffman unfortunately invested his money in a transatlantic merchant ship which was sunk, with its entire cargo, by a German submarine. Again penniless, he began the manufacture of suspenders, in a small way, with money I loaned him, but was not very successful. Then he conceived the idea of a new projectile, very effective and quite different from others. He asked our company to finance him while he was experimenting and perfecting the new projectile. The company couldn't undertake to do that, but I personally financed Mr. Kauffman, having confidence in his ability. He has been six months getting the invention made, tested and ready to submit to government experts, and up to the present it has cost a lot of money. However, it is now considered perfect and Mr. Kauffman has brought it here to-night to exhibit and explain it to Mr. Colton. If Mr. Colton approves it from a manufacturing standpoint, our company will secure an option for the sole right to manufacture it."

"Mr. Kauffman has been in Dorfield several days," said Josie. "Why did he not show you the projectile before?"

"I have been out of town," explained the manager. "I returned this afternoon, especially for this interview, and made the appointment for this evening. I am a busy man—these are war times, you know—and I must make my evenings count as well as my days."

Josie scented ignominous defeat, but she had one more shot to fire.

"Mrs. Charleworth," she stated, with a severe look, "John Dyer, the school superintendent, was at your house last night, in secret conference with Mr. Kauffman and yourself."

"Oh, so you are aware of that interview?"

"Clever!" said Kauffman, "I'd no idea I was being shadowed." Then the two exchanged glances and smiled. "It seems impossible," continued the man, "to keep any little matter of business dark, these days, although the war office insists on secrecy in regard to all munitions affairs and publicity would surely ruin our chances of getting the new projectile accepted for government use."

"I am awaiting an explanation of that meeting," declared Josie sternly. "Perhaps you do not realize how important it may be."

"Well," answered Mrs. Charleworth, a thoughtful expression crossing her pleasant face, "I see no objection to acquainting you with the object of that mysterious meeting, although it involves confiding to you a bit of necessary diplomacy. Mr. Colton will tell you that the Dorfield Steel Works will under no circumstances purchase the right to manufacture the Kauffman projectile—or any other article of munition— until it is approved and adopted by the War Department. That approval is not easily obtained, because the officials are crowded with business and a certain amount of red tape must be encountered. Experience has proved that the inventor is not the proper person to secure government endorsement; he labors under a natural disadvantage. Neither is Mr. Colton, as the prospective manufacturer, free from suspicion of selfish interest. Therefore it seemed best to have the matter taken up with the proper authorities and experts by someone not financially interested in the projectile.

"Now, Professor Dyer has a brother-in-law who is an important member of the munitions board, under General Crozier, and we have induced the professor, after much urging, to take our projectile to Washington, have it tested, and secure contracts for its manufacture. If he succeeds, we are to pay liberally for his services. That was how he came to be at our house last evening, when arrangements were finally made."

"Was such secrecy necessary?" asked Josie suspiciously.

It was Kauffman who answered this question, speaking with apparent good humor but with a tinge of sarcasm in his voice: "My dear young lady, your own disposition to secrecy—a quality quite necessary in a detective—should show you the absurdity of your question. Can we be too careful in these days of espionage? No emissary of the Kaiser must know the construction of this wonderful projectile; none should even know that it exists. Even should our government refuse to adopt it; we must not let the Central Powers know of it. My own negotiations with Mr. Colton and Mrs. Charleworth have been camouflaged by my disguise as a suspender merchant. It was equally important that Mr. Dyer's connection with us be wholly unsuspected. When the projectile is adopted, and these works are manufacturing it in quantities to help win the war, still no information concerning it must be made public. You must realize that."

"That is all true," agreed Mr. Colton. "These frank statements, miss, have only been made to you because of your claim to being a government agent. If you fail to substantiate that claim, we shall place you under arrest and turn you over to the authorities, for our own protection."

"To be sure," said Josie; "that will be your duty. I am the daughter of John O'Gorman, one of the high officers of the United States Secret Service, who is now in Europe in the interests of the government. I came to Dorfield to visit my friend, Mary Louise Burrows, as Mrs. Charleworth is aware, and while here my suspicions were aroused of the existence of a German spy plot. Therefore I set to work to bring the criminals to justice."

"And, like the regulation detective, you have followed a false trail," commented Kauffman, with his provoking smile.

"Not altogether," retorted Josie. "I have already secured proof that will convict two persons, at least. And I am amazed that you have intrusted your secrets to that arch-traitor, Professor Dyer. Will you tell me, Mrs. Charleworth, what you know about that man?"

Mrs. Charleworth seemed astounded.

"Professor John Dyer is one of Dorfield's old residents, I believe," she answered slowly, as if carefully considering her words. "He is also the superintendent of schools, and in that capacity seems highly respected. I have never heard anything against the man, until now. His important public position should vouch for his integrity."

"Isn't his position a political appointment?" inquired Josie.

The lady looked at Mr. Colton. "Yes," said the manager. "It is true that John Dyer was active in politics long before he was made superintendent of schools. However, he was an educator, as well as a politician, so it seems his appointment was merited."

"How well do you know him personally, madam?" asked the girl.

"Not very well," she admitted. "We do not meet socially, so our acquaintance until very recently was casual. But I have looked upon him as a man of importance in the community. On learning that he had a relative on the munitions board, I asked him to come, to my house, where I made him the proposition to take our projectile to Washington and secure its adoption. I offered liberal terms for such service, but at first the professor seemed not interested. I arranged a second meeting, last evening, at which Mr. Kauffman was present to explain technical details, and we soon persuaded Mr. Dyer to undertake the commission. We felt that we could trust him implicity."

"When did he intend to go to Washington?" was Josie's next question.

"On the 5:30, to-morrow morning. After exhibiting the projectile to Mr. Colton and securing the firm's option to manufacture it on a royalty basis, we are to take it to my house, where Mr. Dyer will receive it and obtain our final instructions."

"One question more, if you please," said Josie. "What connection with your enterprise has Tom Linnet?"

"Linnet? I do not know such a person," declared Mrs. Charleworth.

"Who is he?" asked the manager.

"I know him," said Kauffman. "He's the night clerk at the Mansion House where I stop. Sometimes I see him when I come in late. He's not of special account; he's weak, ignorant, and—"

A sharp report interrupted him and alarmed them all.

Josie swung around quickly, for the sound—she knew it was a revolver shot—came from the rear. As Colton and Kauffman sprang to their feet and Mrs. Charleworth shrank back in a fright, the girl ran to the back door, opened it and started to make her way through the huge, dark building beyond the partition. The manager followed in her wake and as he passed through the door he turned a switch which flooded the big store-room with light.

In the center of the building were long, broad tables, used for packing. A few shells still remained grouped here and there upon the boards. On either side the walls were lined with tiers of boxes bound with steel bands and ready for shipment. No person was visible in this room, but at the farther end an outer door stood ajar and just outside it a motionless form was outlined.

Josie and Mr. Colton, approaching this outer door nearly at the same time, controlled their haste and came to an abrupt halt. The upright figure was that of Sergeant Joe Langley and the light from the room just reached a human form huddled upon the ground a few feet distant. Joe had dropped his flashlight and in his one hand held a revolver. Josie drew a long, shuddering breath. The manager took a step forward, hesitated, and returned to his former position, his face deathly white.

"What is it? What's the matter?" called Kauffman, coming upon the scene panting for he was too short and fat to run easily.

Joe turned and looked at them as if waking from a trance. His stolid face took on a shamed expression.

"Couldn't help it, sir," he said to the manager. "I caught him in the act. It was the flashlight that saved us. When it struck him he looked up and the bullet hit him fair."

"Who is it, and what was he doing?" asked Mr. Colton hoarsely.

"It's under him, sir, and he was a-lighting of it."

As he spoke, Sergeant Joe approached the form and with a shove of his foot pushed it over. It rolled slightly, unbent, and now lay at full length, facing them. Josie picked up the flashlight and turned it upon the face.

"Oh!" she cried aloud, and shivered anew, but was not surprised.

"I guess," said Joe slowly, "they'll have to get another school superintendent."

"But what's it all about? What did he do?" demanded Kauffman excitedly.

Joe took the light from Josie's hand and turned it upon a curious object that until now had been hidden by the dead man's body.

"It's a infernal machine, sir, an' I ain't sure, even yet, that it won't go off an' blow us all up. He was leanin' down an' bendin' over it, twisting that dial you see, when on a sudden I spotted him. I didn't stop to think. My Cap'n used to say 'Act first an' think afterwards,' an' that's what I did. I didn't know till now it was the school boss, but it wouldn't have made any difference. I done my duty as I saw it, an' I hope I did it right, Mr. Colton."

Kauffman was already stooping over the machine, examining it with a skilled mechanical eye.

"It's ticking!" he said, and began turning the dial backward to zero. The ticking stopped. Then the inventor stood, up and with his handkerchief wiped the perspiration from his face.

"Gott!" he exclaimed, "this is no joke. We've all been too near death to feel comfortable."

"This is horrible!" said Mr. Colton, "I can't yet believe that Dyer could be guilty of so fiendish an act."

"I can," asserted Josie grimly, "and it isn't the first time he has planned murder, either. Dyer was responsible for the explosion at the airplane factory."

Footsteps were heard. Out of the darkness between the group of buildings appeared two men, Crissey and Addison.

"Are we too late, Miss O'Gorman?" asked Crissey.

"Yes," she replied. "How did you lose track of Dyer?"

"He's a slippery fellow," said Addison, "and threw us off the scent. But finally we traced him here and—"

"And there he is," concluded Josie in a reproachful tone.

Crissey caught sight of the machine.

"Great Caesar!" he exclaimed, "who saved you?"

"I did," answered Joe, putting the revolver in his hip pocket, "but I wish you'd had the job, stranger."

CHAPTER XXIV AFTER THE CRISIS

Mrs. Charleworth drove Josie, who was sobbing nervously and quite bereft of her usual self-command, to Colonel Hathaway's residence. The woman was unnerved, too, and had little to say on the journey.

The old colonel had retired, but Mary Louise was still up, reading a book, and she was shocked when Josie came running in and threw herself into her friend's arms, crying and laughing by turns, hysterically.

"What's the matter, dear?" asked Mary Louise in an anxious voice.

"I've b-b-bungled that whole miserable G-Ger-man spy plot!" wailed Josie.

"Wasn't there any plot, then?"

"Of course; but I g-grabbed the wrong end of it. Oh, I'm so glad Daddy wasn't here to see my humiliation! I'm a dub, Mary Louise—a miserable, ignorant, foozle-brained dub!"

"Never mind, dear," said Mary Louise consolingly. "No one can know everything, Josie, even at our age. Now sit down and wipe that wet off your face and tell me all about it."

Josie complied. She snivelled a little as she began her story, but soon became more calm. Indeed, in her relation she tried to place the facts in such order that she might herself find excuse for her erroneous theories, as well as prove to Mary Louise that her suspicions of Abe Kauffman and Mrs. Charleworth were well founded.

"No girl is supposed to know the difference between a bomb and a cannon-ball—or projectile—or whatever it is," was her friend's comment, when Josie had reached the scene in the manager's office, "and any man who is a German and acts queerly is surely open to suspicion. Go on, Josie; what happened next?"

Even Mary Louise was startled and horrified at the terrible retribution that had overtaken Professor Dyer, although Josie's story had aroused her indignation toward him and prepared her for the man's final infamous attempt to wreck the steel plant.

"And what about Tom Linnet?" she asked.

"Chief Farnum is to arrest him to-night," said Josie. "He will confess everything, of course, and then the whole plot will be made public."

"Poor Mrs. Dyer!" sighed Mary Louise.

But fate decreed a different ending to the night's tragedy. When the police tried to arrest Tom Linnet the young man was not to be found. He had not bought the cigar store, but with what funds remained to him, he had absconded to parts unknown.

Chief Farnum wired his description to all parts of the country. Meantime, on the morning after the affair at the steel works, an earnest conference was held between Mr. Colton, Colonel Hathaway, Josie O'Gorman, Mrs. Charleworth, the Chief of Police and the two secret service agents. At this conference it was deemed inadvisable to acquaint the public with the truth about John Dyer's villainy. The government would be fully informed, of course, but it seemed best not to tell the people of Dorfield that a supposedly respectable citizen had been in the pay of the Kaiser's agents. It would be likely to make them suspicious of one another and have a bad influence generally. The criminal had paid the penalty of his crimes. The murders he had committed and attempted to commit were avenged.

So it was announced that the school superintendent had been killed by an accidental explosion at the munition works, and the newspapers stated that Mrs. Dyer did not desire a public funeral. Indeed, she was too overwhelmed by the tragedy to express any desire regarding the funeral but left it all to Colonel Hathaway and Mr. Colton, who volunteered to attend to the arrangements. The burial was very unostentatious and the widow received much sympathy and did not suffer in the esteem of the community. Mrs. Dyer, in fact, was never told of her husband's dishonor and so mourned him sincerely.

Immediately following the conference referred to, Josie brought the Chief of Police and the secret service men to her room and in their presence dragged the old pedestal-desk from her closet. Mary Louise, who had been admitted, exclaimed in surprise:

"Why, Josie! I thought you sent the desk to Washington."

"No," answered Josie, "I merely shipped an empty box. I knew very well that Dyer would try to get back the desk, hoping I had not discovered its secret, so I deceived him and gained time by proving that I had sent a box home by freight."

"That explains his decision to take the projectile to Washington," commented Detective Crissey, "he believed he could kill two birds with one stone—get back his papers and earn a big fee from Mrs. Charleworth."

"Also," added Josie, "he would be able to give the German Master Spy full information concerning the projectile, and so reap another reward. But all his diabolical schemes were frustrated by Joe Langley's bullet."

"Well, here's the desk," said Chief Farnum, "but where are those important papers, Miss O'Gorman?"

"And what do they prove?" added Crissey.

Josie slid back the panel in the square pedestal, disclosing the two compartments filled with papers. These she allowed the police and the detectives to read, arid they not only proved that John Dyer was in the pay of an organized band of German spies having agents in Washington, New York and Chicago, but Crissey was confident the notes, contracts and agreements would furnish clues leading to the discovery and apprehension of the entire band. So the papers were placed in his charge to take to Washington, and their importance was a further argument for secrecy concerning John Dyer's death.

"So far as I am concerned," Josie said afterward to Colonel Hathaway and Mary Louise, "the spy case is ended. When they arrest Tom Linnet they will be able to prove, from the scraps of paper I found in the printing room of the hotel, that Linnet printed the circulars from copy furnished by Dyer, and that Dyer and Linnet together directed the envelopes, probably in the still hours of the morning at the hotel desk, where they were not likely to be disturbed. The circulars may not be considered legally treasonable, but the fact that Linnet personally placed the bomb that destroyed the airplane works will surely send him to the scaffold."

"I suppose you will be called as a witness," suggested Mary Louise, "because you are the only one who overheard his verbal confession of the crime."

"It wont take much to make Linnet confess," predicted Josie. "He is yellow all through, or he wouldn't have undertaken such dastardly work for the sake of money. His refusal to undertake the second job was mere cowardice, not repentance. I understand that sort of criminal pretty well, and I assure you he will confess as soon as he is captured."

But, somewhat to the astonishment of the officers, Tom Linnet managed to evade capture. They found his trail once or twice, and lost it again. After a time they discovered he had escaped into Mexico; afterward they heard of a young man of his description in Argentine; finally he disappeared altogether.

The arms of the law are long and strong, far-reaching and mercilessly persistent. They may embrace Tom Linnet yet, but until now he has miraculously avoided them.

CHAPTER XXV DECORATING

Colonel Hathaway and Mary Louise were walking down the street one day when they noticed that the front of Jake Kasker's Clothing Emporium was fairly covered with American flags. Even the signs were hidden by a fluttering display of the Stars and Stripes.

"I wonder what this means?" said the colonel.

"Let's go in and inquire," proposed Mary Louise. "I don't suppose the man has forgiven me yet for suspecting his loyalty, but you've always defended him, Gran'pa Jim, so he will probably tell you why he is celebrating."

They entered the store and Kasker came forward to meet them.

"What's the meaning of all the flags, Jake?" asked the colonel.

"Didn't you hear?" said Kasker. "My boy's been shot—my little Jakie!" Tears came to his eyes.

"Dear me!" exclaimed Mary Louise, with ready sympathy; "I hope he—he isn't dead?"

"No," said Kasker, wiping his eyes, "not that, thank God. A shell splinter took out a piece of his leg—my little Jakie's leg!—and he's in a hospital at Soissons. His letter says in a few weeks he can go back to his company. I got a letter from his captain, too. The captain says Jakie is a good soldier and fights like wild-cats. That's what he says of Jakie!"

"Still," said Colonel Hathaway, with a puzzled look, "I do not quite understand why you should decorate so profusely on account of so sad an event."

"Sad!" exclaimed the clothing man, "not a bit. That's glory, the way I look at it, Colonel. If my Jakie's blood is spilled for his country, and he can go back and spill it again, it makes great honor for the name of Kasker. Say, once they called me pro-German, 'cause I said I hated the war. Don't my Jakie's blood put my name on America's honor roll? I'm pretty proud of Jakie," he wiped his eyes again; "I'll give him an interest in the business, if he comes back. And if he don't—if those cursed Germans put an end to him—then folks will say, 'See Jake Kasker over there? Well, he gave his son for his country—his only son.' Seems to me, Colonel, that evens the score. America gives us Germans protection and prosperity, and we give our blood to defend America's honor. I'm sorry I couldn't find a place for any more flags."

The colonel and Mary Louise were both a little awed, but as Kasker accompanied them to the door, they strove to express their sympathy and approval. As they parted, however, the man leaned over and whispered: "Just the same, I hate the war. But, if it has to be, let's stand together to fight and win it!" * * * * * * * * "Gran'pa Jim," said Mary Louise, when they were on the street again, "I'm ashamed. I once told you I loved you better than my country, but Jake Kasker loves his country better than his son."

CHAPTER XXVI KEEPING BUSY

The Liberty Girls were forced to abandon their Shop when a substantial offer was made by a business firm to rent the store they had occupied. However, they were then, near the end of their resources, with depleted stock, for they had begged about all the odds and ends people would consent to part with. What goods remained to them were of inferior worth and slow to dispose of, so they concluded their enterprise with a "grand auction," Peter Conant acting as auctioneer, and cleaned up the entire stock "in a blaze of glory," as Mary Louise enthusiastically described the event.

The venture had been remarkably successful and many a soldier had cause to bless the Liberty Girls' Shop for substantial comforts provided from its funds.

"But what can we do now," inquired Mary Louise anxiously as the six captains met with Irene one afternoon following the closing of the shop. "We must keep busy, of course. Can't someone think of something?"

One and all had been thinking on that subject, it seemed. Various proposals were advanced, none of which, however, seemed entirely practical until Irene said:

"We mustn't lose our reputation for originality, you know, nor must we interfere with those who are doing war relief work as well, if not much better, than we could. I've pondered the case some, during the past few days, and in reading of the progress of events I find that quite the most important thing on the government programme, at present, is the conservation of foods. 'Food will win the war' is the latest slogan, and anyone who can help Mr. Hoover will be doing the utmost for our final victory."

"That's all very well, Irene," said Alora, "but I'm sure we are all as careful as possible to conserve food."

"Don't ask us to eat any less," pleaded Edna, "for my appetite rebels as it is."

"I don't see how we Liberty Girls can possibly help Mr. Hoover more than everyone else is doing," remarked Laura.

"Well, I've an idea we can," replied Irene. "But this is just another case where I can only plan, and you girls must execute. Now, listen to my proposition. The most necessary thing to conserve, it seems, is wheat."

"So it seems, dear."

"People are eating large quantities of wheat flour simply because they don't know what else to eat," Irene continued. "Now, corn, properly prepared, is far more delicious and equally as nourishing as wheat. The trouble is that people don't know how to use corn-meal and corn-flour to the best advantage."

"That is true; and they're not likely to learn in time to apply the knowledge usefully," commented Mary Louise.

"Not unless you girls get busy and teach them," admitted Irene, while a smile went round the circle. "Don't laugh, girls. You are all very fair cooks, and if properly trained in the methods of preparing corn for food, you could easily teach others, and soon all Dorfield would be eating corn and conserving wheat. That would be worth while, wouldn't it?"

"But who's to train us, and how could we manage to train others?" asked Mary Louise.

"The proposition sounds interesting, Irene, and if carried through would doubtless be valuable, but is it practical?"

"Let us see," was the reply. "Some time ago I read of the wonderful success of Mrs. Manton in preparing corn for food. She's one of the most famous professional cooks in America and her name is already a household word. We use her cook-book every day. Now, Mrs. Manton has been teaching classes in Cleveland, and I wrote her and asked what she would charge to come here and teach the Liberty Girls the practical methods of preparing her numerous corn recipes. Here's her answer, girls. She wants her expenses and one hundred dollars for two weeks' work, and she will come next week if we telegraph her at once."

They considered and discussed this proposition very seriously.

"At the Masonic Temple," said Mary Louise, "there is a large and fully equipped kitchen, adjoining the lodge room, and it is not in use except on special occasions. Gran'pa Jim is a high Mason, and so is Alora's father. Perhaps they could secure permission for us to use the lodge kitchen for our class in cookery."

The colonel and Jason Jones, being consulted, promised the use of the kitchen and highly approved the plan of the Liberty Girls. Mrs. Manton was telegraphed to come to Dorfield and the cookery class was soon formed. Alora confessed she had no talent whatever for cooking, but all the other five were ready to undertake the work and a selection was made from among the other Liberty Girls—of the rank and file—which brought the total number of culinary endeavorers up to fifteen—as large a class as Mrs. Manton was able to handle efficiently.

While these fifteen were being trained, by means of practical daily demonstration, in the many appetizing preparations for the table from corn-meal and corn-flour, Alora and one or two others daily visited the homes of Dorfield and left samples of bread, buns, cookies, cakes, desserts and other things that had come fresh from the ovens and range of the cooking-school. At the same time an offer was made to teach the family cook—whether mistress or servant—in this patriotic branch of culinary art, and such offers were usually accepted with eagerness, especially after tasting the delicious corn dainties.

When Mrs. Manton left Dorfield, after two weeks of successful work, she left fifteen Liberty Girls fully competent to teach others how to prepare every one of her famous corn recipes. And these fifteen, divided into "shifts" and with several large kitchens at their disposal, immediately found themselves besieged by applicants for instruction. Before winter set in, all Dorfield, as predicted by Irene, was eating corn, and liking it better than wheat, and in proof of their success, the Liberty Girls received a highly complimentary letter from Mr. Hoover, thanking them for their help in the time of the nation's greatest need. A fee, sufficient to cover the cost of the material used, had been exacted from all those willing and able to pay for instruction, so no expense was involved in this work aside from the charges of Mrs. Manton, which were cared for by voluntary subscription on the part of a few who were interested in the girls' patriotic project.

Another thing the Liberty Girls did was to start "Community Concerts" one evening each week, which were held in various churches and attended by throngs of men, women and children who joined lustily in the singing of patriotic and popular songs. This community singing became immensely popular and did much to promote patriotic fervor as well as to entertain those in attendance.

And so Mary Louise's Liberty Girls, at the time this story ends, are still active workers in the cause of liberty, justice and democracy, and will continue to support their country's welfare as long as they can be of use.

"We're a real part of the war," Mary Louise has often told her co-workers, "and I'm sure that in the final day of glorious victory our girls will be found to have played no unimportant part."
