WHICH COPS ARE CROOKS?

New to Line of Duty? Here’s a handy guide to its morally ambiguous cast of characters

SUPERINTENDENT TED HASTINGS

HASTINGS (Adrian Dunbar) is the boss, the moral core and beating heart of Line Of Duty. Or is he? A Masonic handshake with a retired senior office accused of being involved in a child sex ring threw suspicion on him last week. He is good but flawed. His wife left him in series two, over his gambling debts.

DI COTTAN

NOW unmasked as The Caddy — the corrupt police officer DI Matthew Cottan (Craig Parkinson) is mad and bad — but can he carry on fooling his colleagues?

DC KATE FLEMING

POSSESSED of an unnerving, pale blue 30-yard stare. Has now launched her own inquiry into Hastings because she fears he is trying to help a fellow Freemason. She sort of fancies Cottan — or does she?

LINDSAY DENTON

ROGUE detective played by Keeley Hawes (below). Morally ambiguous, she has battered her neighbour, been jailed for a murder conspiracy and beaten up her creepy parole officer. She was shot in the head by evil Cottan last week after refusing to take a bribe. Why not take the money? ‘Because I am a police officer,’ she screamed.

DS STEVE ARNOTT

LADIES’ man Arnott’s troubled relationship with DI Denton — did they have a fling? — meant his judgment is open to question. Now Denton has been killed in Arnott’s car, could he be framed by Cottan for her murder? His only hope is Kate, but could she be turning on him?

GILL BIGELOW

SAUCY Gill (Polly Walker) is the legal adviser to AC-12. Seems to want to scupper the child sex abuse inquiry, but why? Last week she suddenly came out as a Cottan supporter. It’s all very suspicious.
