City of Fallen Angels: atmospheric detective noir set in a suffocating LA heat wave

Summer, 1962. A scorching heat wave is suffocating L.A. PI John Keegan is offered a small fortune to find a beautiful woman from a set of photographs. He refuses; the job seems suspicious. But the next day the same woman, Eve, turns up, unbidden, on his doorstep. Eve fears for her safety. She is being watched. Before Keegan knows it, someone has been killed with Keegan's own gun, and he gets sucked into a world of suspicion and betrayal where he's never quite sure where the truth lies. Before long he's the prime suspect in a murder he didn't commit, and all the evidence seems to point in his direction. It's almost like someone planned it that way.
