Someone has murdered euthanasia champion Dr. Eldon Mate - a self-styled Dr. Death responsible for scores of assisted suicides. In a burst of bloody irony, the killer chooses to dispatch the doctor in the back of Mate's own suicide van, hooking him up to the killing apparatus dubbed "the Humanitron" - and adding some butchering touches of his own. The case is assigned to veteran LAPD homicide detective Milo Sturgis, who turns once again to his friend Dr. Alex Delaware.

Brilliant, beautiful, and stunningly effective, psychologist Dr. Grace Blades has a special gift for treating troubled souls and healing tormented psyches - perhaps because she bears her own invisible scars. Only five years old when she witnessed her parents die in a bloody murder-suicide, Grace took refuge in her towering intellect and found comfort in the loving couple who adopted her. But as an adult, Grace's accomplished professional life vies with a covert, high-risk dark side, played out harrowingly. And when Grace's two worlds shockingly converge, her past returns with a vengeance.
