In SUSPECT ZERO, FBI Agent Tom Mackelway finds himself caught in a cat-and-mouse game with a brutal serial killer, and all clues point to a renegade agent "gone native." Trained by the government to use his psychic abilities to track and capture other serial killers, the renegade is killing other serial killers and claims to be in pursuit of the ultimate serial killer, a man he calls Suspect Zero. As Mackelway becomes increasingly obsessed with his suspect, he must decide what happens when pursuer and prey come face to face – and if rational justice or primal revenge will prevail.
