"And I've had my trousers' pockets picked!"

"And the half-dollar I left on the bureau is gone!"

Such were some of the excited exclamations which the Rover boys heard when they went downstairs the next morning. The speakers were the youths who occupied Dormitories Numbers 3 and 4, at the rear of the main upper hall. An inquiry among the lads elicited the information that everybody had suffered excepting one boy, who said he had not had any money on hand.

"I spent my last cent for the spread," he grinned. "I guess I'm the lucky one."

The news of the robberies created a profound sensation throughout Putnam Hall, and both Captain Putnam and George Strong were very much disturbed.

"We never had such a thing occur before," said the captain, and he ordered a strict investigation.

All told, something like thirty-two dollars were missing, and also a gold watch, a silver watch, and several shirt-studs of more or less value. Among the shirt-studs was one set with a ruby belonging to a cadet named Weeks.

The investigation revealed nothing of importance. The robbery had been committed during the night, while the owners of the money and the various articles slept.

"I must get at the bottom of this affair," said Captain Putnam.
"The honor of the academy is at stake."

He talked to all of those who had lost anything and promised to make the matter good. Then he asked each if he had any suspicions regarding the thief or thieves. No one had, and for the time being it looked as if the case must fall to the ground.
