The keynote of American civilization is a sort of warm-hearted vulgarity. The Americans have none of the irony of the English, none of their cool poise, none of their manner. But they do have friendliness. Where an Englishman would give you his card, an American would very likely give you his shirt.
Raymond ChandlerThe average detective story is probably no worse than the average novel, but you never see the average novel. It doesn't get published. The average -- or only slightly above average -- detective story does.... Whereas the good novel is not at all the same kind of book as the bad novel. It is about entirely different things. But the good detective story and the bad detective story are about exactly the same things, and they are about them in very much the same way.
