In his essay ‘The Simple Art of Murder’, Raymond Chandler describes the world of the American detective story as ‘a world in which gangsters can rule nations and almost rule cities, in which hotels and apartment houses and celebrated restaurants are owned by men who made their money out of brothels, in which a screen star can be the fingerman for a mob, and the nice man down the hall is a boss of the numbers racket; a world where a judge with a cellar full of bootleg liquor can send a man to jail for having a pint in his pocket, where the mayor of your town may have condoned murder as an instrument of money making, where no man can walk down a dark street in safety’. Nevertheless, ‘down these mean streets a man must go who is not himself mean, who is neither tarnished nor afraid. The detective in this kind of story must be such a man. He is the hero, he is everything. He must be a complete man and a common man and yet an unusual man. He must be, to use a rather weathered phrase, a man of honour, by instinct, by inevitability, without thought of it, and certainly without saying it. He must be the best man in his world and a good enough man for any world.’ What are the possibilities of being such a man (or woman) in the world as we know it? The hero of the American detective story (of the Hammett-Chandler genre) is not only a good man, and a man of honour, but also a man who must get things done. In Dashiel Hammett's Red Harvest he is the man who is sent in to clean up the pig-sty that is Poisonville, and in so doing he becomes poisoned himself. He has a choice between being effective and being good, but he cannot be both together. ‘Poisonville is right’, he says despairingly. ‘It's poisoned me.’
