Instinct

Dr Dylan Reinhart is an expert on criminal behaviour. But when his best-selling book is found at a gruesome murder scene, Dylan comes face to face with the real world of crime. And the killer is expecting him. Elizabeth Needham, the brilliant NYPD detective leading the case, recruits Dylan to help investigate another clue the killer has left behind - a playing card. Is this the killer's signature? Or will the cards lead them to the next victim, and right into the Dealer's hands? The Dealer's twisted game will test everything Dylan thought he knew about the criminal mind.

An unconventional alliance between the cops and the brilliant Professor Dylan Reinhart once helped take a serial killer off the streets of Manhattan. Now, the police are facing another impossible case that's wreaking havoc in the city. And only Professor Reinhart can connect the clues.

Imagine everyone's surprise when Carter von Oehson, a sophomore in Dr Dylan Reinhart's abnormal psychology class, posts on Instagram that he plans to kill himself. Twenty-four hours later and still no one has seen him. A massive search ensues. But when Carter's sailboat rolls in with the tide without him or anyone else on it, the worst seems to be confirmed. He really did it...or did he?
