Falling Angel - William Hjortsberg

Big-band frontman Johnny Favorite was singing for the troops when a Luftwaffe fighter squadron strafed the bandstand, killing the crowd and leaving the singer near death. The army returned him to a private hospital in upstate New York, leaving him to live out his days as a vegetable while the world forgot him. But Louis Cyphre never forgets.

Cyphre had a contract with the singer, stipulating payment upon Johnny's death-payment that will be denied as long as Johnny clings to life. When Cyphre hires private investigator Harry Angel to find Johnny at the hospital, Angel learns that the singer has disappeared. It is no ordinary missing-person's case. Everyone he questions dies soon after, as Angel's investigation ensnares him in a bizarre tangle of black magic, carnival freaks, and grisly voodoo. When the sinister Louis Cyphre begins appearing in Angel's dreams, the detective fears for his life, his sanity, and his soul.

Falling Angel was the basis for the Alan Parker film Angel Heart, starring Mickey Rourke, Robert De Niro, and Lisa Bonet.
