I think I may claim that his famous character Raffles was a kind of inversion of Sherlock Holmes, Bunny playing Watson. He admits as much in his kindly dedication. I think there are few finer examples of short-story writing in our language than these, though I confess I think they are rather dangerous in their suggestion. I told him so before he put pen to paper, and the result has, I fear, borne me out. You must not make the criminal a hero.
