Retired FBI profiler Terry McCaleb has traded manhunts for a quiet life on Catalina Island — until a sheriff's detective asks him to consult on a single, strange murder. The victim was found bound with wire, a bucket over his head and an obscure message left at the scene, and McCaleb's old instincts read a ritual killer with a taste for punishment.
Across the water in Los Angeles, Harry Bosch is the star witness in a sensational trial, having built the case against a celebrated film director accused of murder. As McCaleb studies his ritual killing, its threads begin to twist toward Bosch's world — and toward Bosch himself. Two of Michael Connelly's investigators, each certain of his own reading of the evidence, are set on a collision course.
The seventh Harry Bosch novel braids the Bosch books together with Connelly's Blood Work into a tense, cerebral study of obsession, guilt, and the fine line between the hunter and the hunted.
