"That is true, Dismal, and I want you to do your best to find out who the man is. Make a sure thing of it. Get positive proof, if possible."

"Whoever he is his sin is sure to find him out."

There were footsteps on the stairs and the sound of laughing voices. The door burst open and several freshmen came trooping in, as if they felt quite at home there. Lucy Little was at their head, and his face showed excitement.

"I say, Merriwell!" he cried, "are you out for a little sport to-night?"

"That depends on what sort of sport it is."

"'Sh!" said Little, mysteriously. "Close the door, uncle."

A fellow by the name of Silas Blossom, who was familiarly called "uncle," obeyed.

Little looked at Rattleton and then stared hard at Jones, who had the face of a parson.

"I don't know about you," he said, "but I think you are all right. Even if you have scruples I don't believe you will blow."

"Very kind!" grunted Dismal.
