DI Chandler returns in this atmospheric, brooding drama. Back in the 1960s, twins Ronnie and Reggie Kray ruled the East End of London through organized crime, bringing murder and violence to the streets of Whitechapel. When a man's mutilated body surfaces in the Thames, Chandler and his team begin to suspect someone is murdering old gangland mobsters in the manner of the Krays to fast track themselves to the top of the underworld. But who would have the power and the sway to do such a thing? Matters take a turn for the worse when it would seem that the gangsters aren't just killing their own, they are prepared to kill anyone who gets in their way - and in this instance it is Chandler, Miles, McCormack and Kent.
