"How comes it that Marston knows of this secret?"
"His sister must have told him," I replied.
"His sister!" he repeated. "Why, you never met her before this month."
"I told her on the first occasion that I met her. She was in some measure concerned in it."
He looked at me shrewdly.
"She was engaged to Sir Julian Harnwood," said he.
I nodded assent.
He brought his fist down on the table with a bang.
"The trouble springs from that cursed journey of yours to Bristol. I warned you harm would come of it. Had Lady Tracy any reason to fear you?"
"None," I replied promptly.
