In the final episode of Line of Duty, BBC Two’s hard-hitting new thriller series exploring the world of police corruption, Gates still believes he can save his career and marriage, if only he can prove his innocence. Meanwhile, Arnott is forced to decide where his loyalties lie, while Fleming and Hastings go all out to catch Gates – leading to a shattering conclusion.

Episode 5 airs at 9pm on Tuesday 24th July on BBC Two. In the meantime, here are ten teasing lines of dialogue from the episode…

» “They killed Sammy!”

» “You’re out on a limb Arnott. Not a great place to be when the inquest opens next week.”

» “Quite a set of charges isn’t it, for the Officer of the Year? Conspiracy, kidnapping, GBH, attempted murder…”

» “No one wants to step into a dead man’s shoes, but Tony Gates is finished.”

» “Where’s the body Ryan?!”

» “Her cover wasn’t the only thing that was blown…just ask Gates.”

» “There’s a bigger crime here.”

» “You’re under arrest for the double murder at Greek Lane, for the murder of Leslie Duke, for the murder of Jacqueline Laverty.”

» “There was a freezer, in the place they held me. That struck me as odd…”

» “I swear to tell the truth, the whole truth, and nothing but the truth.”
