The Museum of Desire by Jonathan Kellerman, 348 pages

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, and a variety of methods have been used to dispatch them. As Alex and Milo make their way through blind alleys and mazes baited with misdirection, they encounter a crime so vicious that it stretches the definitions of evil.
