"h.e.l.lo!" laughed Rodney, lifting his eyebrows. "The great detective is on the job. I judge you have inside information, Pipe?"

"Very little," answered Sleuth; "but if I set out to get it I'll not be balked. Once I take up a case worthy of my attention, I am relentless as Fate."

"Do you have an idea this matter is a case worthy of your attention?"

asked Nelson, winking slyly at Grant.

"That I can't answer," confessed Sleuth; "but it's my theory that persons whose movements are secretive and mysterious deserve to be watched. Possibly I can tell you one little fact of which you are unaware."

"Let flicker," invited Jack. "We're listening, all agog."

"For some little time," said Sleuth, in answer to this invitation, "certain fellows have been meeting regularly every Sat.u.r.day night in the rooms of Ned Osgood."

"Is that all?" exclaimed Grant, disappointed. "Why, I suppose, as Osgood happens to be such a popular chap, they merely drop in on him for a social call."

"Is there any reason why a fellow who is merely making a social call should shroud his movements in secrecy?" questioned Sleuth instantly.

"If you were going to drop round to see Osgood for a little pleasant chat of a Sat.u.r.day evening would you take pains to prevent the fact from becoming known? Or would you, if meeting a friend on your way, openly and frankly tell him where you were going?"

"I don't opine I'd be covering up my tracks any whatever."

"Not unless it was to be something more than a mere social call," nodded Sleuth decisively. "By apparent chance it has happened that I have met on different occasions two or three of these fellows who were on their way to call upon Osgood, and when I asked them where they were going they either lied or begged the question. Ha! Now you perceive that there must be some hidden motive for this secrecy. A man who takes extreme pains to conceal his motives should be watched."

"There's certain some logic in that," admitted the Texan; "but I'll allow I don't see what those fellows could be up to that would concern anybody but themselves."

Nelson, however, was thoughtful, frowning the least bit.

"It may not concern any one else," he said presently, "and, then again, it may. It may be my fault, but I can't quite trust Osgood. I'll admit that he acted pretty decent in practically acknowledging that he was wrong to-day; but all the time I couldn't help feeling that he was playing policy, while thoroughly satisfied that he had been in the right and that I was a chump to call for the sacrifice. As a matter between us three, there's a feeling of dissension on the team as well as in the school, and I'm sure that Osgood and Shultz are behind it. When I benched Osgood it wouldn't have surprised me in the least if some of the players besides Shultz had made an objection. He has got a grip on them, and they think he knows more baseball than I or any of the old players.

I've seen them imitating his methods and his style of play. When a ball team loses confidence in the judgment of its captain, that team soon gets into a bad way."

"I didn't like the talk Shultz made about Prof. Richardson," said Grant.

"The old boy may not take a natural modern interest in athletics, but you sure hit the nail on the head, Nelson, when you said that he does his work well in the cla.s.s room and therefore makes a good princ.i.p.al.

But I suppose I'd likely object to almost anything coming from Shultz.

There's something about that fellow that certain rubs my fur the wrong way."

"He's irritating," agreed Jack; "but I can't help thinking that Osgood is the more dangerous man. If there's trouble, you'll find that he will really be the leader."

"Oh, I don't judge there will really be any trouble," said Rodney optimistically. "If there was any brewing, I think you nipped it in the bud, captain. I've got to hike home, or Aunt Priscilla will begin to worry; she always does if I'm late to meals. Good night."

Sleuth pulled at Nelson's sleeve. "Wait a minute," he requested in a low tone. "I've a powerful suspicion that you're right in thinking there's trouble brewing-there's something going on beneath the surface. I'm going to investigate. I'm going to take this matter up professionally.

I'll pierce the dark depths of the plot. I'll lay it bare in all its heinous nakedness."

"Go as far as you like, Sleuth," smiled Nelson. "As far as I'm concerned you have free rein, but don't drag me into it in any way."

CHAPTER VII

YOUNG SPORTS.

After shivering for more than half an hour beneath a tree across the street from Mrs. Chester's home, Sleuth Piper finally decided to make a move. Since seeking the hiding shelter of that tree he had seen four boys ascend the widow's steps, ring the bell and obtain admission. It was now some time since the last one had disappeared within the house, and Piper believed no more were to follow.

There was a light in Osgood's room on the second floor, but the shades were closely drawn at the windows. Sleuth would have given much had he been able to look through those windows, but being prevented from doing so, he had decided on a bold move.

Swiftly crossing the road, he softly mounted the steps and hastily gave a single ring at the bell. After a few moments the summons was answered by a maid, and the boy boldly entered the moment the door swung open.

"I'm to see Osgood," he said in a low tone. "I'm a little late. I presume the other fellows are ahead of me?"

"Mr. Osgood has several friends with him in his room," said the girl.

"He's expecting you, isn't he?"

"Why, sure," returned Piper, although even in his "professional capacity" his conscience was troubled by the falsehood, which surely was something quite surprising in a detective.

By the m.u.f.fled hall light the boy deliberately mounted the carpeted stairs. He heard the maid retire, and the sound of the door closing behind her was most gratifying to his ears.

There was little trouble in finding the door of Osgood's room, for from behind it came the subdued murmur of voices; and, listening, Piper heard at intervals a queer, soft, irregular clicking sound. But when he would have taken a peep through the keyhole, he was much disappointed to find it either plugged or covered on the inside by something that baffled him.

"And that proves there's something queer going on," he whispered to himself. "They're not talking loud, either; they're keeping their voices down. A lot of fellows who get together and chat free and easy don't bother to talk that way. Wish I could hear something more."

After a time, growing desperate through the intensity of his increasing curiosity, he placed his hand gently on the k.n.o.b of the door with his ear close to the panel, and, when the talk seemed to be a bit more general inside, he softly and slowly turned the k.n.o.b.

The door was locked!

"That settles it," he mentally exclaimed. "There's something off color taking place here."

Still with the utmost caution, he permitted the spring slowly to force the catch back into place and removed his hand from the k.n.o.b.

"There's just one thing to do now," he decided; "I've got to put on a bold front. It's the only play for me to make."

Lifting his hand, he knocked softly upon the door.

Immediately the hum of voices ceased, and after a little Sleuth fancied he heard some one whisper within the room.

He knocked again.

There was the sound of a person stirring, and the key turned in the lock. The door was opened the tiniest crack, and the voice of Osgood asked:

"Who is it? What's wanted?"

"h.e.l.lo, Ned," called Sleuth, as he again grasped the k.n.o.b and gave the door a push which flung it wide open. "Thought I'd come round for a little call this-- Why, you've got company! Excuse me."

The scene beheld by Piper's eyes caused them to grow unusually big and round. Within the room four boys remained seated around a table covered by a green cloth and lighted by a shaded suspension lamp. On that table were red, white and blue poker chips and some cards. In each fellow's hand were also the cards which he had held when play had been interrupted by Sleuth's knock. The young gamesters looked somewhat startled, an expression which gave way to annoyance as they recognized the unwelcome caller.

"How the d.i.c.kens did you get into the house?" exclaimed Osgood, in a manner that was, for him, unusually rude.

"Why," returned Sleuth instantly, "I just said I came round to make you a little call. But if I'm not welcome--"

"Old Pipe always has his nose into everything," laughed Chipper Cooper, one of the quartet at the table. "As long as he's here to call, bring him in and let him do his calling in the game."
