Confounded and convinced a woman is behind it all, the local police call in the International Crime Bureau's expert on female killers: criminal profiler Alyssa Rawkesby, accompanied by her new rookie partner, Thayer Volikov.

Alyssa never thought she'd relate so strongly to a killer's letter. But once she reads it, she knows there is no going back.
