"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."
