Gillingham, the shock which your sudden appearance gave me? Can you imagine the feelings of a “murderer” who has (as he thinks) planned for every possibility, and is then confronted suddenly with an utterly new problem? What difference would your coming make? I didn’t know. Perhaps none; perhaps all. And I had forgotten to open the window!

I don’t know whether you will think my plan for killing Mark a clever one. Perhaps not. But if I do deserve any praise in the matter, I think I deserve it for the way I pulled myself together in the face of the unexpected catastrophe of your arrival. Yes, I got a window open,

Mr.
