I don’t know that it’s a very satisfactory theory. In my young days, I always was told that sleepwalkers couldn’t hurt themselves⁠—that their own sixth sense took care of them. I don’t think the theory satisfies Mrs. Blair either.

I can’t make that woman out. Her whole attitude towards Race has changed. She watches him now like a cat a mouse, and she makes obvious efforts to bring herself to be civil to him. And they used to be such friends. Altogether she is unlike herself, nervous, hysterical, starting and jumping at the least sound. I am beginning to think that it is high time I went to Jo’burg.
