Detective Inspector Jonathan Cain is set for the island of Menorca to visit his brother and family when he receives a phone call from his partner DS Lucy Able. A body has been found in Serpentine Woods and it has all the marks of the media dubbed serial murderer Kimberley Killer.
From 2009 to 2010 Kimberley Killer terrorised the Cumbrian town of Kendal, butchering ten men and three women. Kimberley Killer was never caught and it remains the only case D.I Cain hasn't solved. But after a two year absence Cain has promised himself that this time he will catch her once and for all.
