 I'm a peculiar guy. I don't like the perfect crime, not even in books. So? You're a twin expert. Do you know anything, whatever, about these two dames that would give me a chance to begin work? Oh, sure. The crime. You don't just suppose anyone could commit a murder, do you? Look, you're going to have to be very patient with me. Just what do you mean by that? Character, personality. Not even nature can duplicate character, even in twins.
