"I don't like to tell what I know," said Tom, hesitating.

"But I want you to. You introduced me, you know."

"What I know is not to his advantage. I don't like to talk against a man."

"You needn't mind telling me."

On reflection Tom decided that he ought to tell what he knew, for he felt that Jennie ought to be put on her guard against a man whom he did not consider a suitable acquaintance for her.

"Very well," said he, "if you promise not to let him know that I have told you."

"I promise."

"He was my roommate last night at the Pittsburg House," said Tom, in a low voice. "During the night he tried to rob me."

"You don't say so!" ejaculated Jennie, in round-eyed wonder.

"I will tell you the particulars."
