Line of Duty
Season 3 Episode 6 of 6
The third series of Jed Mercurio's police procedural began with a big twist when Daniel Mays' bad guy was killed off at the end of episode one. After four equally gripping episodes which delved further into the corruption scandal hinted at in series one and two - and reintroduced Keeley Hawes as anti-hero Lindsay Denton - it seems the feature-length finale promises to up the ante as one of the AC-12 officers finds themselves on the other side of the interview table on suspicion of murder. AC-12 legal counsel Gill Biggeloe puts pressure on Supt Ted Hastings, only for new evidence to turn the inquiry on its head. An undercover investigation may provide the key - but will the unit ever uncover the truth about 'the Caddy'? Martin Compston, Vicky McClure, Adrian Dunbar and Polly Walker star
