CHAPTER XIII.

THE ANONYMOUS LETTER.

A very short time after the capture of Skip Riley, Ted Strong was standing in the waiting room of the Union Station at St. Louis, the metropolis of Missouri, whither he had been summoned by a letter from the chief of the United States secret service.

He was waiting for Bud Morgan, who had gone to the baggage room to inquire about a trunk which had become lost on the way from Moon Valley, and which contained a number of valuable papers, including both their commissions as deputy United States marshals.

The enormous waiting room was crowded with passengers from the incoming trains, with which the numerous tracks were full from end to end.

As Ted Strong leaned over the iron railing, looking down into the lower waiting room, he was conscious that a woman had stepped to his side. Glancing up sideways, he saw that close to him was a very beautiful young girl, who wore a traveling cloak of pearl gray, and a long feather boa, which the draft had blown across his sleeve.

His glance intercepted one from her, and not wishing her to think that he was idly staring at her, he directed his gaze once more to the surging crowd below. As his eyes wandered over the throng, he saw a man look up, and make the most imperceptible gesture with his head.

He did not know the man. Turning swiftly to the young lady at his side, he caught sight of a smile and a slight uplifting of her eyebrows.

Undoubtedly a signal had passed between the two, and Ted, not wishing to be an eavesdropper, looked away again. But in the swift glance he had given the young girl—for now he saw that she was little else—he made a mental note of her. The gray eyes with the long, dark lashes, the oval face, beautiful in shape and of an ivory tint; the scarlet, curving lips, the slender, trim figure, and the strange, subtle perfume which she exhaled, one would never forget.

He also noted the appearance of the man who had signaled the girl.

The man was five feet seven inches in height; his face was well rounded, but not too fat. He had a brown, pointed beard; the eyes were pale, almost colorless; the forehead, broad and high, a fact which Ted noted when the man lifted his hat to wipe his brow. He had the air of a well-bred man of the world, and was probably a resident of New York. There was something familiar about the man that made Ted think that he had seen him before.

Ted saw Bud come through the door into the waiting room from the midway of the station, look up and wave his hand, with a frown and a shake of the head that told him his pard's quest for the missing baggage had been fruitless.

At the same time, the girl at his side seemed to bump into him, and as he turned to her she muttered an apology and hurried away. Although he followed her with his eyes a few moments, she was soon lost in the crowd.

He slipped his hands into the pockets of his jacket, and, with his back to the railing, prepared to wait until Bud reached him.

As his left hand sank into his pocket, his fingers came in contact with a piece of paper.

He knew that he had not placed the paper in his pocket, and glanced around with his usual caution to see if any one was watching him. He saw that wonderful pair of gray eyes with the dark lashes—Irish eyes, he called them—watching him over the shoulders of a man a dozen feet away in the crowd. But the moment the woman realized that she was being observed, she disappeared.

"Deuced strange," he muttered to himself, fumbling with the paper, which he had not withdrawn from his pocket. "That girl placed this paper in my pocket. I wonder why. There is something out of the way here, for the paper was not there before she stood beside me."

One less wise than Ted, and not so modest, might have thought that the girl was trying to flirt with him. But to Ted there was something more important and mysterious than that in her actions.

If he read them aright, she had placed the paper in his pocket when she apparently accidentally bumped into him, and had gone away only to come back to see if he had discovered it.

Although he searched the crowd with eager eyes, he did not see her again, and was confident that she had disappeared as soon as she had accomplished her mission, which was to convey some message to him.

Although he was somewhat curious to know what, if anything, was written on the paper, he restrained himself until he could be alone, for he did not know who might be in that crowd looking for just such a move on his part.

Just then Bud brushed his way through the crowd and came up to Ted.

"Them things ain't come yit," he said, in a tone of discontent, "an' me stranded in St. Looey with no more clean shirt than a rabbit."

"You can easily get a clean shirt," said Ted, "but it's not so easy to get a new commission. That's what's worrying me, for there is no telling how soon we may need one."

"Well, let's git out o' this mob, er I'll begin ter beller an' mill, an' if they don't git out o' my way I'll cause sech a stampede thet it'll take ther police all day ter round 'em up ag'in."

Ted said nothing to Bud about the paper he had discovered in his pocket, but picked up his valise. They then made their way to the street and rode uptown in a car, where they registered at a quiet hotel.

Ted went immediately to the room assigned to him, locked the door, and drew out the paper.

He could not conceive what it would contain, for he was far above the vanity of thinking that the young woman who had stood by his side would interest herself in him enough to write him a silly note.

"The man with the pointed beard!" thought Ted.

Of course, it was he who had caused the note to be slipped into his pocket.

But why?

Taking a chair by the window, he slowly opened the note, observing at the time that the same fragrance came from it as had filled the air while the girl stood beside him in the station.

It was a sheet of pale-blue letter paper folded three times.

In the upper left-hand corner was an embossed crest, the head of a lion rampant, and beneath it a dainty monogram, which he made out to be "O. B. N.," or any one of the combinations of those letters. He could not tell which combination was the correct one.

The writing was in a fashionable feminine hand, and written with a pencil.

It was as follows:

"T. S.: This is a friendly warning from one who dare not communicate with you personally, for reasons which you will discover and understand later on, if things turn out as we"—the word "we" had been scratched out and "I" written above it—"anticipate. Be very careful while you are in St. Louis. Do not go on the streets alone, and go armed. Your mission is known, and you will be watched by persons who will seek to get you out of the way. We—that is, I, also know of your mission, and take this means of warning you of your danger, as you have done me services in the past without knowing it. Now, the sting of this note lies in this, and don't forget it, don't get into any fights, no matter what the provocation, for I have it straight that that, is the lay to do you. If you do so, not being able to avoid it, shoot straight, and you will come out all right in the end. I will see to that part of it at the right time.

"A FRIEND."

Ted read the letter through three times, trying to clarify it, but each time his mind became more confused over it.

What did it mean, and how could any stranger know his business when he had not told a soul about it?

Even Bud did not know why they were in St. Louis; that is, he did not know the real reason. Ostensibly, they were there to inspect the local horse market.

There was a loud rap on the door, and Ted went to it and unlocked it. Throwing the door open, he saw a stranger standing on the threshold, just about to step in.

He looked at Ted in apparent surprise, then up at the number on the door, but his eyes fell to the letter which Ted still held in his hand, and he stared at it like one fascinated.

Ted noticed this, and put the letter behind his back.

As the stranger did not speak, Ted broke the spell by saying, in a sarcastic tone:

"Well?"

"Oh, I beg your pardon," said the stranger hastily, "but isn't Mr. Fowle in? I expected him to come to the door, and was surprised to see you, don't you know."

"I don't know any Mr. Fowle," said Ted, with a smile that must have told the stranger that he was not taken in by the question.

The fellow threw a quick glance around the room, but did not retreat from his place in the doorway.

Ted was starting to shut the door, considering the incident closed, when the stranger, who was a large, powerful man, well dressed and with the air of a prosperous business man, started to enter.

"This is not Mr. Fowle's room; it is mine," said Ted, blocking the way,

"I'll just step in and wait for him," said the man. "The clerk downstairs said it was his room."

"Wait a minute," said Ted sternly. "I don't know you, and I don't know Fowle. If you have any business with me, state it from the hall."

The warning in the letter flashed through his mind.

Suddenly the man sprang upon Ted, and they fell to the floor together.

"Give me that letter, curse you!" hissed the man, "I saw you get it, and I saw it just now. Give it to me, I tell you."

Ted had managed to put the letter back into his pocket. His right arm was twisted under his body, and he could not release it.

He looked up into the face of the man, who was straddling his body, and saw a gleam of malignant hatred in his eyes.

"Let me up, you cur," said Ted.

"After I get the letter," was the reply.

"It's a private letter, and not for you. Let me up!"

Now Ted saw that the man had a knife in his hand—a long, keen knife, with a pearl hilt and a silver guard.

"If you don't give me that letter at once, you'll not get another chance, but I'll have it," snarled the man.

Ted began to struggle, but he soon saw that he could do nothing with one arm out of commission. The man was not only powerful, but heavy, and it was all Ted could do to more than wriggle his body.

"I tell you you shan't have it," said Ted.

The knife went above the man's head, and in the wielder's face was a look of the most diabolical hatred Ted had ever seen in a human countenance.

"For the last time," said the man hoarsely.

There was something about the fellow's actions that told Ted he was desperate, yet at the same time afraid of the act he was about to commit.

The knife was about to descend when Ted cried out an alarm, the first he had sounded.

He heard some one running in the hall. His assailant heard it, also, and hesitated, looking around with frightened eyes.

"Yi-yipee!" It was Bud's voice, and Ted breathed a prayer of thankfulness.

"I'll give it to you, anyhow," muttered the man, and again the knife went up in the air.

But it did not make a strike, for at that moment Bud bounded into the room, and, taking in the situation with a lightning glance, his foot flew out, and the toe of his heavy boot struck the man on top of Ted fairly in the ribs. There was a cracking sound, and with a groan the fellow dropped the knife and struggled to his feet.

Rushing at Bud, he bowled that doughty individual over like a tenpin, and dashed into the hall, along which he ran swiftly and lightly, for so large a man.

When Bud had picked himself up and run to the stairway, he could hear the fellow clattering down the stairs three flights below.

"Well, dash my hopes," said Bud, "if he didn't get clear away. He shore treated me like a leetle boy. But I reckon he's in sech a hurry because he's on his way ter a drug store fer a porious plaster fer them ribs o' hisn."

Ted had picked himself up and was rubbing his arm, which had been strained by his falling on it.

"What's this yere all erbout?" asked Bud. "I'm comin' up ter call on yer when I hears yer blat, an' I come runnin', an' what do I see? A large, pale stranger erbout ter explore yer system with er bowie. Yer mixin' in sassiety quicker'n usual, seems ter me."

Ted had picked up the knife, which had fallen beneath the bed, and was looking at it.

"I wonder where this came from," he said, turning it over in his hand.

"Wherever it came from, it's a wicked-lookin' cuss," said Bud. "But what wuz ther feller goin' ter explore yer with it fer?"

"This letter," said Ted, taking the crumpled paper from his pocket and handing it to Bud.

"Jumpin' sand hills, ther plot thickens," said Bud, when he had finished reading it. "I don't seem ter be in it at all. What's it all erbout? Ye've got my coco whirlin' shore."
