“That is possible, Professor. But is there any one in the place that you suspect?”

At this Professor Grawson shook his head.

“No, sir. So far as I can imagine they are all thoroughly honest.”

“We might institute a general search of all the buildings,” announced Captain Dale. “We can call all the cadets out on the campus and all the hired help into the mess room and request them to remain while the search is going on.”

“Some of the hired help may object to that,” came from Professor Watson.

“If they did it would throw suspicion on them,” answered Colonel Colby quickly. “I think the idea had better be carried out.”

All the persons in the school were assembled as mentioned, and then Captain Dale explained to the cadets what had been proposed and Colonel Colby did the same to the hired help.

“They’re certainly welcome to search our rooms,” declared Major Jack promptly.

“And mine, too,” added a score of others.

“I’m sure I haven’t anything to conceal,” put in Lieutenant Harkness.
