DI Chandler, DC Miles and the team investigate a series of brutal killings and maimings. Local history expert Buchan suggests that London once more has a copycat killer - only this time the murders mirror killings by the Kray twins in the 1960s. Miles and Chandler refuse to believe Buchan's theory since the Krays are both dead - but is Buchan on the right path?

Miles learns that a criminal called Billy Bunhill has been shot inside another notorious Kray haunt, The Blind Beggar pub. Chandler's interest is piqued when he realises that the murder mirrors George Cornell's killing by Ronnie Kray in 1966. Who could possibly be trading off the ghosts of the Krays and using their legend to invoke fear and paranoia on the streets of Whitechapel? When the threats become personal and the killer seems to be one step ahead, Chandler and Miles have to wonder just how far the murderer's power reaches.

Last in the series of the gripping crime drama. With the body count rising and nothing conclusive to pin on the twins, Chandler and his team have no option but to play the Krays at their own game. But the clock is ticking and the team are forced underground. Can Chandler get his man or will the streets of Whitechapel continue to run with blood?
