Lieutenant Lucas Davenport, highly touted killer detective, invents intricate video games that he sells for cash. Called in to aid the Minneapolis team scrambling to stop a psychopathic serial woman-slayer, Lucas almost meets his match. The self-styled "mad dog" murderer views his rape/stabbings as a game as well, setting up obstacles for the police, carefully selecting his victims, and priding himself on clever moves. Despite his largely deja vu plot, debut novelist Sandford delivers tense action, chilling excitement, and thrilling suspense. Fast-moving prose and romantic sidelines add a little zest, too.
