Compulsion (Alex Delaware #22) by Jonathan Kellerman

Once again, the depths of the criminal mind and the darkest side of a glittering city fuel #1 New York Times bestselling author Jonathan Kellerman’s brilliant storytelling. And no one conducts a more harrowing and suspenseful manhunt than the modern Sherlock Holmes of the psyche, Dr. Alex Delaware.

A tipsy young woman seeking aid on a desolate highway disappears into the inky black night. A retired schoolteacher is stabbed to death in broad daylight. Two women are butchered after closing time in a small-town beauty parlor. These and other bizarre acts of cruelty and psychopathology are linked only by the killer’s use of luxury vehicles and a baffling lack of motive. The ultimate whodunits, these crimes demand the attention of LAPD detective Milo Sturgis and his collaborator on the crime beat, psychologist Alex Delaware.
