'It's all over now, Maggie. I will release you.' Afraid, alone, and forsaken. A killer is stalking the historic West End streets of Fremantle preying upon the women of the port city. When a third lifeless body is found discarded in a dank alleyway with her throat ripped open, Detective Sergeant Claire Patterson is convinced she is dealing with a serial killer. For DS Patterson, this is her first time leading a major investigation, and she's intent on proving she has what it takes, even if it means working with the antagonising DS Michael Halliday. As the murders grip the city with fear, Claire Patterson must learn to trust Halliday if she is to catch a killer before he strikes again.
