All you need to know ahead of series 3 of the award-winning police anti-corruption drama.

Mother of God! DS Arnott, DI Fleming and Superintendent Hastings are back and only interested in one thing, catching bent coppers. In an exclusive ‘deleted’ scene from series five, all three can be seen interrogating DC Taylor, an accused corrupt copper (played by Jason Isaacs) who they suspect knows the identity of the real ‘H’. Unfortunately for DC Taylor, his representation comes in the form of ineffective lawyer David Rickman (played by Lee Mack).
