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 organised 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.
