Stumbling to the ground, he claws at the earth around him, trying to stabilise himself, but his attacker is on him in seconds. As he stares at the lights of the bustling streets on the other side of the park gates, he doesn’t even have time to yell for help before everything goes black.
When the body of wealthy businessman Charles Stott is found dead on Wimbledon Common, covered in bruises just feet away from his luxury home, Detective Dan Lockhart is called to investigate the shocking scene. Examining the sickeningly disfigured body before him, Lockhart knows he’s dealing with a brutal killer and, as he bends down to take a closer look, he notices something on the victim’s neck: a small, crudely drawn symbol in black ink. It seems the murderer has marked his victim, but why? Dan needs to get inside the perpetrator’s mind, so he contacts psychologist Dr Lexi Green.
