When Silence Kills

When the mutilated body of a prostitute is discovered in her home, DCI Bishop from the Met murder squad is called in to oversee the case. The woman's eyes have been stabbed repeatedly and a child-like stick-man drawing has been left as a calling card. A post-mortem also detects a cocktail of GHB and chloroform - a terrifying mixture that can leave the victim screaming in silence. No one would have heard her cry for help. The horrific killing bears a striking resemblance to three other murders years before, but the cases were never solved and DI Bishop knows he needs the help of forensic psychologist Holly Wakefield. Holly is brilliant at getting into the minds of psychopaths and suspects Bishop is missing a vital clue that links the victims. But can they find the link before the killer comes knocking on Holly's door?
