***Special anniversary edition, with a new introduction from Peter James***

He almost took your life. Now his is in your hands...

When Leanne, a homeless young girl, is murdered beside a canal in North London, the police are certain that known oddball Michael Doll is the killer.

Psychologist Kit Quinn, assisting the investigation, has her own reasons to despise Doll - but she soon realises that the case is more complicated than the investigators suspect.

Because Kit has found a link to another death. Which means they might have a serial killer on their hands...
