“He’s coming out,” declared Ned.
“So much the better,” commented Frank.
An instant later the front door opened and the man who had gone in, hurried out. He seemed in great haste for, giving a quick look around, he darted away from the school, down the front walk, and up the street.
“Fellows, that was no janitor!” declared Bart. “I believe he was a burglar!”
“But he didn’t have any bundles,” declared Frank. “If he had stolen anything, he’d have to pack it up, as anything of value in the school is quite bulky. I don’t believe he took anything.”
“Then why did he run?” demanded Bart.
This was a poser for his chums, until Frank said:
“It may have been one of the teachers who went back after some papers he forgot.”
“Didn’t look like any of the teachers,” said Bart. “Besides the teachers wouldn’t run, as if the police were after them, and they wouldn’t act as frightened as that man did.”
“Well, what are we going to do about it?” asked Ned. “If we’re going to play that joke, let’s get busy. We won’t say anything about seeing the man unless something developes, and I don’t believe it will. Come on in. The front door seems to be open. We can go in that way, instead of around through the court; less chance of Riggs seeing us.”
