Was it suicide ... or murder? Detective Sergeant Solomon Gray is driven to discover the truth. Whatever the personal cost.

When teenager Nick Buckingham tumbles from the fifth floor of an apartment block, Detective Sergeant Solomon Gray answers the call with a sick feeling in his stomach. The victim was just a kid, sixteen years old. And the exact age the detective's son was, the son Gray has not seen since he went missing at a funfair ten years ago. Each case involving children haunts Gray with the reminder that his son may still be out there – or worse, dead. The seemingly open and shut case of suicide twists into a darker discovery. Buckingham and Gray have never met, so why is Gray's number on the dead teenager's mobile phone?
