Jesus, Mary, Joseph and the wee donkey: a new teaser trailer for Line of Duty’s series six finale promises an explosive conclusion to AC-12’s biggest case yet.

Sunday night’s episode saw the demise of baby-faced bent copper Ryan Pilkington (Gregory Piper), which prompted Kate Fleming (Vicky McClure) and Jo Davidson (Kelly Macdonald) to embark on a Thelma and Louise-style escape plan that was eventually foiled by ultimate killjoy Pat Carmichael (Anna Maxwell Martin).

Davidson then went on to set a new record for the number of “no comments” uttered during a glass box interrogation, eventually ending up in HMP Brentiss, while AC-12 went international as they tuned in to watch the Guardia Civil break into the home of ‘H’ suspect Marcus Thurwell (James Nesbitt) - only to discover two dead bodies.

Will Steve Arnott (Martin Compston) ever answer those increasingly aggy emails from Occupation Health? Is Pat bent or just auditioning to be a project manager on The Apprentice? Is Thurwell actually dead - and how does Chief Constable Philip Osborne fit into this tangled web of bent coppers? And what was on Gail Vella’s laptop, discovered at the old OCG print shop? All these questions and more will, we hope, be answered during Sunday’s episode.

The new clip shows Davidson apparently being transferred out of prison, asking a guard “What’s going on?” from the back of a van. It looks like time might be up for the most ambiguous bent copper since Keeley Hawes’s Lindsay Denton - if there’s anything this show has taught us, it’s that carefully planned transfer of a suspect never has a happy ending (RIP to Jimmy Lakewell and his tan).

Another shot focuses on a written police report, featuring the world “definate” with that tell-tale spelling mistake highlighted, while AC-12 appear to be gearing up for a major operation, as Ted tells Steve, Chloe and the team that “AFOs will secure the suspect," before another OCG balaclava man emerges from a 4x4. You know s**t is about to hit the fan when the gaffer is wearing one of those bulletproof vests.

Of course, all this prompts another question: is this Line of Duty’s last hurrah? The trailer promises us that “every investigation has led to this,” which certainly suggests that this will be Kate, Steve and Ted’s final act - plus, writer Jed Mercurio has remained coy about whether a seventh series is in the works (the show has only been commissioned up to series six).

Sunday’s episode drew in record overnight ratings of 10.9 million, meaning that if series six is indeed the final one, Line of Duty will be going out on a major high - though we’re not ready to say goodbye to the AC-12 team just yet. Mother of God, when will they put us out of our misery and let us know?

Line of Duty concludes on May 2 at 9pm on BBC One
