"He must have," I insisted; "look at the motor car he drove in: and then his rooms are beautifully furnished."

"He might have got all that by swindling."

"In that case, you certainly are justified in thrashing him, since he obtained an introduction to Lady Denham under false pretences. But I don't think Mr. Monk has the nerve to swindle."

Cannington laughed grimly. I had never seen the easy-going boy so angry. "I think he has the nerve for anything, after what he has done--even for murder, Vance."

I started, remembering my belief that Gertrude was shielding her father. "I don't understand."

"He might have murdered Anne Caldershaw."

"Oh, nonsense. Mr. Monk wasn't even in the neighborhood."

"Mr. Walter Monk, under his real name, wasn't: but Mr. Wentworth Marr was!"

"Cannington?"

"Don't you remember how I told you that Marr called on that mess shortly before we arrived. He was stopping at the Lion Hotel in Murchester, and went off without seeing me again."
