to hustle if I want the
trade. Going to your room?"

"Sure."

"I'll go on ahead and wait for you," said Ikey. "I need the money."

"Say, you're the limit! You're as bad as a sheriff with an attachment,"
complained Dunk. But he could not help laughing at the other's
persistence.

Andy and Dunk were a little late getting back to Wright Hill, and when
they entered their room they found a note on the table. It was from
Ikey, and read:

"I found your door open, and waited a while, but I just heard of a
bargain lot of suspenders I can buy, so I went off to see about them. I
will be back with the socks in a little while."

"He found our door open!" exclaimed Dunk. "Didn't we lock it?"

"We sure did!" declared Andy. "I wonder----" He paused, and looked at

up to-morrow, and he wants to know if we have any evidence that will
help to prove Link innocent."

"Not an awful lot," said Andy, ruefully, "unless this latest robbery is.
We'd better go see that lawyer. Did he say anything about the mysterious
hundred dollars Link got by mail?"

"He mentioned it. There's no explanation of it yet, and he says it will
look queer if it comes out, and if that's the only explanation Link can

"Why need it come out?"

"Oh, it seems that Link showed the bills to several helpers around
college, and some of them have been subpoenaed to testify. The detective
will be sure to bring it out. Then there's that story about the book
found in Link's room."

"Hello!--" exclaimed Andy, looking around the apartment in order to
collect his thoughts. "There's another note someone le
