But time is running out, especially when a body is found dumped in the woods--a woman who's a dead ringer for Louise. How long before Louise's captor gets tired of her and replaces her with another lookalike? How long before they find Louise's corpse next?Now, in order to track a psychopath, Corrigan must place himself in the mind of a killer. For it is only there that the twisted secrets of a murderer lie.
