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?”

“Hello, Ned,” called Sleuth, as he again grasped the knob 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 dickens 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.”

The other three were Charley Shultz, Roy Hooker and Phil Springer. Shultz was scowling darkly and Hooker did not seem exactly pleased; but, like Cooper, Springer appeared to accept the situation good-naturedly.

“Bub-bub-bet he hasn’t any coin with him,” said Phil.

“Come in, Billy,” invited Osgood. “Your unexpected appearance rather upset us. I thought it might be Mrs. Chester or the maid, although we haven’t been making any noise.”
