The museum of desire

"Behind an empty faux castle lurking above Beverly Hills, four bodies are found inside a limousine, arranged in a blood-strewn erotic tableau. Behind the driver, the killer has positioned the bodies of playboy Ricky Gurnsey, street-worn Mary Jane Huralnik, and Benny Alvarez, who recently disappeared from a group home for developmentally delayed adults. It's a psych case if there ever was one, so Homicide Lieutenant Milo Sturgis reaches out to his closest friend, consulting psychologist Alex Delaware. Given the sexualized crime scene, Gurnsey's exploits are a logical starting point, but Milo and Alex shift focus when a staffer from Alvarez's group home is murdered."--
