A killer is loose on the streets of Mildenheath, and his barbaric crimes seem a little too familiar... As the body count begins to rise,  DS Wendy Knight  and  DCI Jack Culverhouse  start to realise that the killer is emulating the  gruesome, grisly murders of the world's most famous and elusive serial killer : Jack the Ripper. With Culverhouse struggling to come to terms with his ex-wife's dramatic return after she disappeared eight and a half years earlier and Knight trying to cope with the trauma she’s suffered following devastating events of two previous cases,  the race is on to stop the killer before he completes his final kill  and retreats back into the darkness. They know he's going to kill again, but they don't know where or who his next victim will be. And what's worse, they don't know who he is either...
