Menaced Assassin — Joe Gores

It began with the murder of a beautiful woman, the adulterous wife of a mild-mannered professor. Then a corrupt cop was gunned down in a phone booth. After that, the killer who called himself Raptor moved through a list of players, playboys, and mobsters from Palm Springs to Minnesota. With each hit came a phone call to San Francisco organized crime investigator Dante Stagnoro, and a disguised, taunting voice daring Stagnoro to stop him. Raptor is a killer like no other Stagnoro has ever pursued. And the final truth of his death trip--a truth about man, nature, and God-will not be revealed until the last victim is claimed.
