 The police have a serial killer on their hands. Two women have been killed in virtually identical circumstances, with their throats slit by what they believe is a straight razor. When they find a man unconscious on the side of railway tracks covered in blood, some of which belonged to the second victim, they re sure they have their man, but he claims complete memory loss. Psychologist Dr. Eddie "Fitz" Fitagerald knew the second second victim Jacqui Appleby and her parents ask him to intervene with the police. Fitz isn t convinced that the man with memory loss is guilty and with the assistance of DS Jane Penhaligon sets out to find the true murderer. On the home front, Fitz is facing new challenges when his wife leaves him upon learning that his gambling has pushed them over the limit on both their credit cards and he also re-mortgaged the house.
