"Now, Bob, I'm going to tell you something," said the oldest Rover, coming to the point without delay. "There has been a robbery here."
"Robbery!" exclaimed the boy. "I didn't do it. I wouldn't take nothin'," he went on, quickly.
"I didn't say you did, Bob. But what I want you to do is to tell me everything that you know. Was there anybody in this office during my absence?"
"Nobody went into this office while I was here," declared the office boy. "I wouldn't let 'em in. But then you must remember, the janitors come in during the night to clean up."
"Oh, yes, I know that."
"Dick, do you think the janitor of the building could be in this?" exclaimed Sam.
"As I have said several times, I don't know what to think," answered Dick. "As a matter of fact, I don't know who the janitor is."
"Say!" broke in the office boy, suddenly. "There was one feller here that I didn't tell you about. I forgot about him. He was here three or four days ago—I don't exactly remember what day it was."
"Who was that?"
"Why, it was a young feller named Barton Pelter. He's a relation to Mr. Pelter. I think Mr. Pelter is his uncle."
