But what am I saying? Did I deceive you at all? You have found out the secret⁠—that Robert was Mark⁠—and that is all that matters. How have you found out? I shall never know now. Where did I go wrong? Perhaps you have been deceiving me all the time. Perhaps you knew about the keys, about the window, even about the secret passage. You are a clever man,

Mr.

Gillingham.
