“Your reminder is needless, sir. Nevertheless, for your greater satisfaction I will reiterate that the letter was destroyed quite a year ago.”

“Well, well. Now did it strike you at the time that any similarity existed between that stranger and the prisoner, Roland Dorrien?”

“It did not.”

“No resemblance whatever? Voice—walk—manner? Come. Think again, my dear sir.”

“Unnecessary. I saw no such resemblance.”

“Has it ever struck you since?”

“It has not.”

“You have never had reason to suspect that Robert Durnford, the rescuer of your daughter on that occasion, might have been Roland Dorrien in disguise?”
