"Why?"

"Because I fancy he has something to do with this crime."

"Lord!" groaned Mrs. Bensusan. "'Ave I waited on a murderer?"

"I don't say he is a murderer, Mrs. Bensusan, but he knows something likely to put us on the track of the criminal."

"What makes ye take up the case?" demanded Rhoda sharply.

"Because I know that Mr. Wrent came to board in this house shortly after Mr. Vrain occupied No. 13," replied Denzil.

"Who says he did?"

"Miss Greeb, my landlady, and she also told me that he left here two days after the murder."

"That's as true as true!" cried Mrs. Bensusan, "ain't it, Rhoda? We lost him 'cause he said he couldn't abide living near a house where a crime had been committed."

"Well, then," continued Lucian, seeing that Rhoda, without speaking, continued to watch him, "the coincidence of Mr. Wrent's stay with that of Mr. Vrain's strikes me as peculiar."
