At 9pm on BBC2 tonight, Matt Smith and Shaun Parkes star in this thrilling new drama that’s set in the heart of London, so if you want to see how the new Doctor measures up, now’s your chance to judge Matt Smith before he steps into the Tardis!

The story of Moses Jones is told over three one-hour episodes which begin when a wave of violence hits London following the discovery of the bizarrely mutilated body of a man in the Thames. First appearances suggest a witchcraft killing, but the dark reality is more complicated – and even more frightening…

Assigned to the case are young hopeful DS Dan Twentyman – Matt Smith – and his senior partner, DI Moses Jones, seconded from Scotland Yard due to his supposed cultural links with the local African community.

Confronted with a wall of silence, Jones and Twentyman become increasingly frustrated, but all roads lead to Joy, her friend Solomon and the Afrigo Club, where the ex-pat community goes to unwind to the irresistible music of Solomon’s band.

As the search deepens, the violence escalates and the investigation grinds to a halt. But one name crops up again and again – Mathias Mutukula, a mysterious godfather figure rumoured to have both terror links and supernatural powers. Forced to ask himself tough questions about his cultural identity, Moses embarks on a frightening quest to track down his man and redeem himself before the community implodes … or takes revenge itself.

Shaun Parkes is Moses Jones, , Eamonn Walker is Solomon Indira Varma is Dolly; and Jude Akuwudike is Matthias. Newcomers Wunmi Mosaku and Obi Abili play Joy and Joseph. Dennis Waterman, who plays Frank Costello, a former boxing champion and brothel owner, makes a guest appearance in episodes two and three.
