‘When I was a copper it was ninety-nine per cent boredom to one per cent terror. I always preferred the one per cent.’

Leslie Grantham (EastEnders) stars as maverick cop Mick Raynor in this six-part thriller set in the no-man’s land where the underworld meets the establishment. While Raynor is posing as a bent ex-policeman, he is still very much part of the force – using his current identity to gain information on a complex web of organised crime and high-level corruption lurking beneath the surface of British public life. Raynor doesn’t make arrests every week. He’s after the big fish: the gangsters with knighthoods, the politicians who are laundering the money. In their pursuit, he faces the most dangerous assignments that will stretch his nerves – and his conscience – to the very limit.

Also starring Robert Stephens (as Raynor’s controller, Commander Oakwood), with appearances by Robert Carlyle and Sharon Duce, 99-1 was written by dramatist and director Terry Johnson, recipient of nine British theatre awards including Olivier Awards for Best Comedy, Playwright of the Year at the Critics’ Circle Theatre Awards, Writers Guild Awards for Best Play for two consecutive years, and the 2010 Tony Award; this first series was produced by BAFTA winner Steve Clark-Hall.
