Ryan Lock is a close-protection operative, a former member of Britain's Royal Corps of Military Police now working in the United States. In Los Angeles, he is hired by Raven Lane, a performer in the "adult entertainment industry" aka porn movies. Raven is being stalked. People she has been in contact with are being gruesomely murdered. The LAPD are on the case which only makes harder the protection for which Lock and his partner are employed.
Sean Black provides a fast-paced, gripping narrative. Inevitably there is a good deal of blood and violence. But there are mitigating factors. Although the milieu is sleazy, the portrayal is clear-eyed about the inherent tawdry exploitation. The author avoids cheap titillation. The characters feel real, the young Down's syndrome sufferer is handled with unsensational care.
Suspense builds and the mystery deepens. The solution is a surprise but there has been no cheating, Lock gets there with logic and perseverance rather than deductive inspiration. We are in Jack Reacher territory, tough guy fiction, and Ryan Lock need not fear comparison.
