A fast-tracked inspector, a hardened detective sergeant, and an expert in historical homicides investigate modern crimes with connections to the past in the Whitechapel district of London.

Set in 2008 and against the hugely atmospheric background of Whitechapel, London, a modern police force are fighting an old adversary. A series of bloody, tragic and impossible crimes would suggest someone is carrying out copycat Jack the Ripper murders.

The murders are investigated by our three unlikely heroes: Chandler, a fast-tracked, media savvy DI on his first big murder case; Miles, nearing retirement, a front-line, hard-bitten DS, and Buchan, the eccentrically brilliant Jack the Ripper tour guide.
