“That’s right,” assented Dunk. “He isn’t a Yale man, but he’s a heap better than the kind in there.” He nodded his head in the direction of their room, where Mortimer now was.

They had left a light burning, and could see, as its beams were cut off now and then, that the intruder was moving about in their apartment.

“Come on, let’s get him—and have it over with,” suggested Dunk.

“No, we’ve got to get the goods on him,” said Andy.

“Well, hasn’t he got plenty of stolen goods—those from the other fellows’ rooms?”

“I know. But if we went in on him now he’d bluff it off—say he came in to borrow a book—or money maybe.”

“But we could search him.”

“You can’t search a fellow for coming to borrow something,” declared Andy. “Come on, let’s go where we can look in.”

Silently they stole forward until they were opposite their door. From it they had a good view of Mortimer.

Just at that moment they saw him reach for the bills on the table and, with a quick motion, pocket them. Then the thief started toward a bureau.
