It's a bit of an oversimplification, but the best way to describe Mosley would be 1/3 Raymond Chandler, 1/3 Ralph Ellison, and 1/3 Albert Camus. Devil in a Blue Dress is the first in a series of spell-binding mysteries revolving around L.A. private detective Easy Rawlings.
After Hammet and Chandler faded away, detective fiction became a cookie-cutter formula with the same old hard-nosed detectives and the usual tangled webs of deceit. Mosley breaks this pattern. Not only does he take a look at the African American situation in the 1940's, but he also places Easy on a road of existentialism as he tries to forge out his own destiny in a white man's world. With a powerful voice, a heck of a story, unforgettable characters, and amazing imagery and symbolism, Mosley will no doubt share the cannon with Poe, Hammet, and Chandler as the only detective writers with any merit.
His books flow well, read easy and quick, leave a lasting impression, and if one is willing, contain many gems to be mined just below the surface. This series is a must read for all lovers of modern literature, detective ficiton lovers, existentialists, and enthusiasts of African American literature.
