A bloodstained coat. Three missing women. One dead body. Detective Mary Hume reckons she's seen it all. But she's never seen anything like this. It begins with the discovery of a broken body in a lift shaft in an old Victorian warehouse. The postmortem reveals the bloodstains on the dead man's coat belong to three different people. DNA identifies one of them as Julie Cross, whose body was discovered six months earlier, covered in horrifying wounds. Maverick ex-police officer Raine was hired to look for Julie. She didn't find Julie in time. But she's determined to find out who killed her. So, who does the rest of the blood belong to? Chalk-and-cheese detective duo Raine and Hume are in a race against time to uncover the truth before more young women die.
