er college rooms, and the call of lads on the campus. From
farther off came the roar and hum of the city. It reminded Andy of the
night he had first come to New Haven. How many things had happened in
that time. He would soon be a sophomore now--no more a callow freshman.

"Do you know," spoke Dunk, in a low voice, as he again changed his
position, seeking ease. "I had an idea that Ikey might turn out to be
the guilty one."

"So did I," admitted Andy. "That was after your watch was missing, and I
found he had been in the room while I was out. But, for that matter,
Link was in there, too. It was a sort of toss-up between the two. Poor
Link, it's been mighty unpleasant for him, to be accused wrongly. I
wonder how that valuable book got in his room?"

"The quadrangle thief put it there, of course."

"And there's that case of Pulter's book--found out near Yale Field,"
went on Andy. "I suppose Mortimer had that, too."

"Very likely, though it seems queer that he'd stoop so low as to take
books."

"He could pawn 'em, I suppose, same as he did the other things he took,"
Andy continued.

"The way he used to borrow money from me and some of the other fellows
was a caution!" exclaimed Dunk. "Seems as though he'd have enough to
worry along on without stealing."

"He spent a lot, though," said Andy. "He was used to high living and I
suppose when he found the money wasn't coming from his father any more
he had to get it the best way he could."

"Or the worst," commented Dunk, grimly. "I know he never paid me back
all he got, and the same way with a lot of the fellows. But if he's
coming I wish he'd show up. I don't wish him any bad luck, and I'd give
a whole lot, even now, if it would prove to be someone else besides
Mortimer. But I'm getting tired of waiting here."

"So am I," said Andy, with a yawn.

Again there was a silence, while they kept their strange vigil. Then,
far down the lower corridor, there sounded footsteps.

"He--he's coming!" whispered Andy in a tense voice.

"Yes," assented Dunk.

But it was a false alarm. As the footsteps came nearer the waiting lads
saw one of the janitors on his rounds. He did not see them, and passed
on.

Andy was doing some hard thinking. The suggestion made by Dunk that the
capture of the thief would be more of a black spot for Yale than the
fact of the robberies taking place was bearing fruit.

"But what can we do?" Andy asked himself. "We've got to stop these
thefts if
