In the third episode of Line of Duty, BBC Two’s hard-hitting new thriller series exploring the world of police corruption, the anticorruption team tries to trap Gates into revealing his involvement in covering up Jackie’s crimes.

Episode 3 airs at 9pm on Tuesday 10th July on BBC Two. In the meantime, here are ten teasing lines of dialogue from the episode…

» “She’s a good looking woman, sir, and we had a past, and there’s no smoke without fire, is there?”

» “Tell me the code!”

» “Take the caution. Home in time for Bargain Hunt.”

» “I push from the outside, you push from the inside, he’ll crack.”

» “Look, I’ve let you down, I had a relationship that’s compromised me professionally, but none of it, really, none of it reflects on you. In fact it makes your loyalty all the more humbling.”

» “Do I have to arrest you? Stand down, Kate.”

» “I’m not going to do your job for you, Arnott. If you want to take me down you’re going to have to do it yourself.”

» “I’ve seen too many ambitious young DI’s looking up the ladder without realising they’ve stepped on a big slippery snake. Know what I mean?”

» “Sorry, what was that about something going down the drain? Would that be your investigation?”

» “You’re over the line here, son; you’re way over the line!”
