All that day and the next I racked my brain over the problem. What had happened? What sort of mind looked out through those alien eyes in Edward's face? I could think of nothing but this dimly terrible enigma, and gave up all efforts to perform my usual work. The second morning the hospital called up to say that the recovered patient was unchanged, and by evening I was close to a nervous collapse—a state I admit, though others will vow it colored my subsequent vision. I have nothing to say on this point except that no madness of mine could account for all the evidence.
