The City of Angels has more than its share of psychopaths, and no one recognizes that more acutely than the brilliant psychologist and police consultant Dr. Alex Delaware.

A series of horrifying events occur in quick succession in the same upscale L.A. neighborhood. A backyard renovation unearths an infant's body, buried 60 years ago. And soon thereafter in a nearby park, another disturbingly bizarre discovery is made not far from the body of a young woman shot in the head. Helping LAPD homicide detective Milo Sturgis to link these eerie incidents is brilliant psychologist Alex Delaware. But even the good doctor's vast experience with matters both clinical and criminal might not be enough.

LAPD Lieutenant Milo Sturgis has solved a lot of murder cases. On many of them - the ones he calls "different" - he taps the brain of brilliant psychologist Dr. Alex Delaware. But neither Alex nor Milo are prepared for what they find on an early morning call to a deserted mansion in Bel Air. This one’s beyond different. This is predation, premeditation, and cruelty on a whole new level. Four people have been slaughtered and left displayed bizarrely and horrifically in a stretch limousine. Confounding the investigation, none of the victims seems to have any connection to any other.
