Motive, opportunity, and no alibi--rookie detective Allison Doyle knows it's as close to a slam dunk as most investigations get. But even though her small-town Texas police department has identified a prime suspect in a young woman's vicious murder, she can't rest easy. And when legendary FBI profiler Mark Wolfe shows up with a startling new theory, all her doubts are amplified. If Wolfe is correct, the real killer is an elusive psychopath who has left a trail of bodies behind him. And he's just days away from his next kill. Allison was supposed to be Wolfe's way into the case, nothing more. But she's ambitious, stubborn, and far too tempting. With the help of her contacts at the Delphi Center crime lab, Wolfe is within striking distance of the monster he's pursued for ten years. Except the closer Allison and Wolfe get, the more reason there is to fear. Because with a predator this brutal, every thread of evidence can make a difference between hunting a madman and becoming hunted yourself.
