Murder Games (Instinct, 1): 9780316273961: Patterson, James

A criminal behavior expert teams up with an NYPD detective to track down a criminal in the novel that inspired the hit CBS TV series starring Alan Cumming.

Dr.

Dylan Reinhart wrote the book on criminal behavior.

Literally: he's a renowned, bestselling Ivy League expert on the subject.

When a copy of his book turns up at a gruesome murder scene-along with a threatening message from the killer-it looks like someone has been taking notes.

Elizabeth Needham is the headstrong and brilliant NYPD Detective in charge of the case who recruits Dylan to help investigate another souvenir left at the scene: a playing card.

Another murder, another card...

and now Dylan suspects that the cards aren't a signature; they're a deadly hint pointing directly toward the next victim.
