The Cheater

Special Agent Mary Stevens works in the Investigative Support Unit at the FBI, a unit that handles the crimes of serial killers. Someone is murdering unfaithful men and dismembering their bodies, playing a cat-and-mouse game with the FBI and with Mary in particular. One of the many tools the killer is using is an “alibi service,” a company that provides alibis to people so that they can have an affair. Can Mary stop the Alibi Murderer when she doesn't even know whether it's a man or a woman?
