A serial killer and his copycat are locked in a violent game of cat and mouse. Can DI Anjelica Henley stop them before it's too late? On the day she returns to active duty with the Serial Crimes Unit, Detective Inspector Anjelica Henley is called to a crime scene. Dismembered body parts from two victims have been found by the river. The modus operandi bears a striking resemblance to Peter Olivier, the notorious Jigsaw Killer, who has spent the past two years behind bars. When he learns that someone is co-opting his grisly signature--the arrangement of victims' limbs in puzzle-piece shapes--he decides to take matters into his own hands. As the body count rises, DI Anjelica Henley is faced with an unspeakable new threat. Can she apprehend the copycat killer before Olivier finds a way to get to him first? Or will she herself become the next victim?
