"I appealed to you, Mr. Merrick, because I was not thoroughly satisfied, in my own mind, of my conclusions. You have added to my doubts, I must confess, yet I cannot abandon the idea that the two men are one and the same. As my suspicion is only shared by you and your niece, in confidence, I shall devote myself for a few days to studying young Jones and observing his actions. In that way I may get a clue that will set all doubt at rest."
