The Neon Rain (Dave Robicheaux, #1)

Detective Dave Robicheaux has fought too many battles: in Vietnam, with killers and hustlers, with police brass, and with the bottle. Lost without his wife's love, Robicheaux's haunted soul mirrors the intensity and dusky mystery of New Orleans' French Quarter -- the place he calls home, and the place that nearly destroys him when he becomes involved in the case of a young prostitute whose body is found in a bayou. Thrust into the world of drug lords and arms smugglers, Robicheaux must face down a subterranean criminal world and come to terms with his own bruised heart in order to survive.
