A serial killer is on the loose in San Francisco.

Only when Lieutenant Larry Foggia is assigned to the case does the true horror of the killer's motive come to light.

A ritual killer - nicknamed 'Satan' - stalks the city, killing in terrible ways with no apparent motive. Enter Lieutenant Foggia who, assisted by a spiritualist medium, must discover the reason for the slayings. But the truth he unearths is beyond anything he's encountered in the real world. For the killings are paving the way for a force so powerful that the lives of a few innocents will appear unimportant in comparison...

Packed with twists, and laced with spiritualism, witchcraft and demonology, Black Angel moves at a break-neck pace from its stomach-churning opening to the explosive final confrontation between man and demon.
