Perry's new thriller takes us on a dangerous cat-and-mouse game that pits two women against each other: one a beautiful, highly manipulative serial killer, the other the detective who is determined to stop her. This murderer changes her appearance and identity with every kill, moving from Portland to San Francisco, to LA, to Las Vegas, with Catherine Hobbs, Portland homicide detective, always just one step behind. Catherine must use everything she has as a woman as well as a detective to stop her. She must learn how to read the murderer's mind. And she is up against a killer who turns to stalking her. Delving deep inside the female psyche, reinterpreting conventions and confounding expectations, this is Perry at his critically acclaimed best.
