“The trouble is that you didn’t take my advice,” Tim denied. “I tried to show you how to work it, but——”
“Never mind,” Barry interposed, thrusting his hands deep into his sweater pockets. “Let’s move along. It’s cold today.”
“It ought to be,” Kent observed. “Christmas is almost here.”
Two high-school boys and a girl passed them and nodded and smiled. “There they go,” the girl cried. “The mystery hunters!”
“Four Sherlocks, the locker-room detectives!” chimed in one of the boys. When this trio had passed on, the four chums looked at one another.
“They seem to keep calling us the mystery hunters,” Barry smiled.
“Just because we found out who was stealing things out of the lockers,” grunted Tim. “That wasn’t such a big job.”
“Anybody could have done it, if he had taken the trouble to,” Kent said.
“The biggest surprise about the whole thing was the fact that a boy like Carter Wolf was doing it,” Mac put in.
Proceeding slowly along the sidewalk toward home, the four boys once more discussed the recent events which had resulted in earning the name of “mystery hunters.” For a long time someone had been stealing athletic supplies and even rings and watches from the gymnasium locker room. Persistent efforts had been made to trap the thief, but without success. Finally the four boys had entered the case, chiefly because a birthday ring of Mac’s had been among the things taken. But for a long time they had not made any progress. The prowler seemed to know exactly what they were about. They even tried sleeping in the locker room, but even this produced no results. Finally they decided on strategy and rigged up a camera. This was placed in another room, at a place in the wall where a single brick had been knocked out. The locker doors were hooked up in such a way that when one of them was opened, the camera would operate.
