Long-haul trucker Michael Fitzgerald finds a dead girl in his bathtub. He insists he doesn't know who she is, but items in her purse and in her apartment suggest otherwise. A video of Michael and the victim having sex certainly seems conclusive, although Michael says it's a fake. So here's the question: Is Michael an innocent man being framed, or is he--as an FBI special agent soon suggests--a serial killer responsible for nearly 20 murders in multiple states? Are there secrets in his past that might explain what's happening now? This collaboration between the prolific Patterson and Barker, author of the excellent 4MK trilogy, has a terrific and frequently surprising plot (don't try to guess what's going to happen next--you'll probably be wrong). With sharp characterizations and natural-sounding dialogue, overall the narrative voice sounds more like Barker's than Patterson's, and in many ways the book is a natural progression from the 4MK novels. Fans of either coauthor will be completely satisfied by this first-rate, no-holds-barred thriller.
