"Schwartz."

"Do you believe Schwartz?"

Cass drew a long, long breath. "I don't know what to believe," he said. "All these men form part of the gang of rogues. There is more devilry in this case than we know of, Bob."

[CHAPTER X]

A STRANGE DENIAL

On arriving at their lodgings, both men were too excited over the case to feel inclined for sleep. Instead of going to bed, they made up the fire, lighted their pipes, and continued the discussion commenced in the hansom. It was then that Ellis repeated the statement of Zirknitz anent his connection with Mrs. Moxton and her sister.

"So you see, Harry, the man is Mrs. Moxton's brother, or half-brother--not her lover."

"He is really no relation at all," retorted Cass, rather amazed by what he heard. "Mrs. Moxton's mother married the father of Zirknitz, did she? That makes the young man brother by marriage, but so far as parentage and blood go, he could marry Mrs. Moxton to-morrow."

"I tell you the man isn't her lover."

"Possibly not, after what Zirknitz has told you--that is, if it is true. But he may be the murderer for all that."
