AC-12 returns to unfinished business after years of backlash over the explosive — and divisive — finale
After years of simmering frustration, Line of Duty is reportedly doing the one thing fans have been demanding since 2021: reopening the hunt for the mysterious villain known as ‘H’.
According to fresh reports, the long-awaited seventh series will pick up exactly where the drama left off — with AC-12 once again chasing the truth behind the shadowy figure at the heart of police corruption.
And for viewers who felt deeply let down by the series six finale, this news feels nothing short of vindication.
The Finale That Sparked Outrage
When bumbling Detective Superintendent Ian Buckells (played by Nigel Boyle) was revealed as ‘H’, many fans accused the show of delivering an anticlimax after nearly a decade of twists, theories, and nail-biting suspense.
Social media erupted.
Petitions circulated.
And the phrase “That can’t be it” became a rallying cry.
Now, it seems the backlash has finally paid off.
“Giving Viewers What They Want”
With filming reportedly set to begin this spring, creator Jed Mercurio is said to be determined to address the lingering anger and deliver a storyline that restores faith in the drama.
A TV insider revealed:
“There was genuine anger about how series six ended — and that played a big part in commissioning a seventh series. This is the first time there’s been any indication the ‘H’ storyline will be revisited, and fans will be thrilled.”
But the reopened hunt won’t come alone.
A New Villain — And a Darker Twist
Alongside the renewed search for ‘H’, series seven will introduce a powerful new storyline involving Detective Inspector Dominic Gough — a celebrated officer whose glittering career comes under scrutiny after he’s accused of abusing his authority.
Sources suggest the new villain’s arc will be intertwined with the ‘H’ conspiracy, creating what insiders describe as a “sensational double-whammy” that could shake the show to its core.
AC-12 Back Together — But Changed
The six-part series will follow AC-12 after it has been disbanded and rebranded, adding a fresh layer of tension and uncertainty.
Returning to lead the charge are:
-
Martin Compston as DI Steve Arnott
-
Vicky McClure as Kate Fleming
-
Adrian Dunbar as Superintendent Ted Hastings
Also making a comeback is Chief Constable Philip Osborne, played by Owen Teale, who remains a sworn enemy of both Arnott and Hastings.
Cast Speak Out: “Now or Never”
Speaking about the return, Jed Mercurio said:
“Everyone involved in Line of Duty feels enormous gratitude to the fans. We’re privileged that so many of you have followed AC-12 for six series, and we couldn’t be more delighted to return.”
Martin Compston called the show “a job of a lifetime”, adding:
“It got to the point where we said, ‘It’s now or never.’ The scripts are already fantastic — proper page-turners.”
Vicky McClure echoed the excitement:
“It goes without saying I’m so excited Line of Duty is back. Belfast — we’ll see you soon.”
