crime fiction

I just read something interesting on Eddie Campbell's blog, about one of the cliches of crime fiction--the whodunit:

There's something that ought to disturb us about turning the tragic
human mess of a murder into a parlour guessing game, as Alan Moore has
said often in reference to his approach to From Hell.

I think that's wise in this day and age, but it shouldn't be. It should be obvious. The rest of the article is here, with examples from old and new stuff in the genre.
