Line of Duty Season 7 Reopens Hunt for Notorious 'H' Villain
The BBC's acclaimed police drama Line of Duty will commence filming next month for its highly anticipated seventh season, with producers confirming the series will reopen the hunt for the mysterious villain known only as 'H'. This development comes five years after the controversial Season 6 finale that supposedly unmasked the criminal mastermind.
The Controversial Revelation That Left Fans Wanting More
In spring 2021, after nine years of intense speculation and countless plot twists, Line of Duty's sixth series appeared to finally reveal 'H' as Detective Superintendent Ian Buckells. However, this revelation proved deeply unsatisfying for many dedicated viewers who perceived the conclusion as anticlimactic and even labeled the entire plotline a 'sham'. The upcoming season promises to address these lingering questions and potentially rewrite what audiences thought they knew about the criminal hierarchy.
Revisiting the Key Suspects in the 'H' Investigation
Throughout Line of Duty's run, virtually every senior officer has come under scrutiny as potential candidates for the elusive 'H'. As Season 7 prepares to relaunch the investigation, we examine the most prominent suspects who might still face examination.
Matthew 'Dot' Cottan: The Original Bombshell
Detective Inspector Matthew "Dot" Cottan, portrayed by Craig Parkinson, delivered the first major breakthrough in the 'H' storyline. Unmasked in Series 3 as a long-standing Organized Crime Group mole, his dying Morse code message suggested a senior officer whose name began with H was still orchestrating events. Despite his dramatic death scene, questions remain about whether Dot took his true identity as 'H' to the grave.
Derek Hilton: The Persistent Obstructionist
Assistant Chief Constable Derek Hilton, played by Paul Higgins, consistently attempted to block AC-12 investigations and frequently clashed with Superintendent Ted Hastings. While confirmed as corrupt with organized crime connections, he was never considered the senior figure AC-12 sought. Could Hilton have been more deeply involved than initially revealed?
Gill Biggeloe: The Legal Mastermind
Gill Biggeloe, portrayed by Polly Walker, shocked viewers when unmasked as part of the OCG network. The articulate senior legal counsel appeared to assist AC-12 while secretly passing intelligence to organized crime. Her arrest demonstrated widespread corruption, though she consistently denied being the mysterious 'H' at the hierarchy's summit.
Ted Hastings: The Unlikely Suspect
Superintendent Ted Hastings, played by Adrian Dunbar, became one of the most startling suspects despite his career dedicated to rooting out corruption. Financial troubles, a concealed laptop, and an enigmatic "H" signature cast doubt on him in Series 5, leading to formal investigation before eventual exoneration. The possibility of his involvement would devastate AC-12.
Philip Osborne: The Ultimate 'Big Boss' Candidate
Chief Constable Philip Osborne, portrayed by Owen Teale, climbed from his Series 1 introduction to the force's pinnacle. His removal from oversight and connections to previous cover-ups made him the prime 'big boss' suspect, with bookmakers placing him at 4/1 before the finale. His unresolved status makes him a significant mystery as investigations resume.
Patricia Carmichael: The Formidable Adversary
AC-3 chief Patricia Carmichael, played by Anna Maxwell Martin, emerged as a compelling suspect in Series 6. Her repeated clashes with Hastings and apparent determination to dismantle AC-12 placed her under intense suspicion, with many viewers convinced she was protecting someone more senior. She briefly topped bookmakers' lists as the likely 'H'.
Jo Davidson: The Blackmaked Investigator
Senior investigating officer Jo Davidson, portrayed by Kelly Macdonald, became central to Series 6 as evidence suggested OCG collaboration. Her undisclosed family connection to organized crime briefly made her a prime 'H' suspect before revelations of blackmail and manipulation. Questions remain about whether her victim persona concealed deeper involvement.
Institutional Corruption Theory
Some audiences theorized that 'H' referenced Hillside Lane Police Station rather than an individual. Multiple corrupt officers were connected to this location, suggesting institutional corruption at senior levels. Whether this theory resurfaces in Season 7 remains uncertain but represents a compelling alternative interpretation.
Ian Buckells: The Controversial Revelation
Following nine years of plot twists, Ian Buckells, portrayed by Nigel Boyle, was unmasked as the "Fourth Man" and supposedly 'H'. The high-ranking officer had discreetly safeguarded OCG operations while maintaining a bumbling persona. Despite being revealed as the final senior corrupt official, Season 7 may cast doubt on whether he truly was the ultimate 'H'.
Production Details and Future Speculation
Filming for Line of Duty Season 7 is scheduled to begin next month, though no transmission date has been announced. The series promises to revisit one of British television's most enduring mysteries, potentially rewriting the narrative that fans thought was concluded in 2021. With numerous unresolved questions and suspicious characters still in play, the hunt for 'H' appears far from over.
