Compulsion

One night a young woman disappears ...In broad daylight a retired teacher is stabbed to death ...In a small-town beauty parlor two women are butchered ...Three baffling cases, linked only by a lack of motive until psychologist Alex Delaware and LAPD Detective Milo Sturgis stumble upon a clue. A stolen luxury car is found undamaged and unblemished — except for a tiny, solitary bloodstain. Soon they uncover other expensive cars 'borrowed' before a killing. Soon the pair are hunting for a multiple killer, from LA high society to its desperate slums, even to New York and a forgotten cold case. However the killer proves to be a fleeting shape-shifter, defying identification. To unmask him, Alex and Milo will have to understand his murderous compulsion.
