The wait for more information on the return of Line of Duty is finally over. The BBC has announced a major new addition to the cast for the upcoming seventh season, and it is a big one. Fans of British television will be happy to hear that Robert Carlyle, the Scottish actor known for his roles in Trainspotting and The Full Monty, is joining the show. He will take on the role of the guest lead for the new series, stepping into the world of AC-12 alongside the familiar faces viewers have followed for years.
This news comes as a treat for followers of the police procedural, which has been off the air since its sixth season ended in 2021. The show is set to begin filming soon, and now with Carlyle on board, excitement is building for what promises to be another tense and twist-filled investigation.
Who is Robert Carlyle Playing in the New Season?
Robert Carlyle will play a character named Detective Constable Shaun Massie. According to details released by the BBC, Massie is not your average desk officer. He is a Specialist Rifle Officer, which means he is a veteran marksman working with a tactical unit called TO-7 . His main job is to help take down organized crime groups operating in the area.
The official description paints DC Massie as a “gruff loner.” He is the type of officer who keeps to himself and does his job without looking for praise. But the character’s storyline takes a serious turn when his boss, DI Dominic Gough, is accused of being a s*xual predator . This accusation shakes Massie to his core and changes his normally detached behavior, pulling him directly into the crosshairs of AC-12’s investigation .
Carlyle himself seems very excited about the role. He mentioned that the scripts for the new season are excellent and that DC Massie is an “extraordinary character” he is looking forward to playing .
The Main Cast is Back Together
Of course, Line of Duty would not be the same without its core team. The “three amigos” are all returning. Martin Compston is back as DS Steve Arnott, Vicky McClure returns as DI Kate Fleming, and Adrian Dunbar will once again play Superintendent Ted Hastings . The chemistry between these three actors has been the heart of the show since it started in 2012.
Their characters are facing big changes when the show returns. The famous anti-corruption unit AC-12 has been disbanded. It is now rebranded as the Inspectorate of Police Standards . This new name suggests a tougher environment for rooting out corruption. Despite the change, Arnott, Fleming, and Hastings are still on the job. They will be assigned what is described as their most sensitive case yet, which likely connects to the accusations against DI Gough .
What is the Storyline for Season 7?
The story for the new season picks up in a difficult time for anti-corruption work. The team will be investigating DI Dominic Gough, a seemingly successful officer who is celebrated for his work against organized crime. But the accusation against him changes everything. The show teases that this case might even be a distraction from an even bigger threat hiding in the background .
There has also been talk about the return of the mysterious “H” storyline. The finale of season six revealed that the bumbling Det Supt Ian Buckells was the elusive fourth man, but many fans were unhappy with that ending. Reports suggest that creator Jed Mercurio might be reopening the hunt for “H” to give viewers the answers they wanted the first time . While the BBC has not officially confirmed this, a source mentioned that the new villain’s storyline could be connected to the “H” mystery .
What the Cast and Creator are Saying
Jed Mercurio, the writer and creator of the show, is clearly thrilled to have Robert Carlyle on board. He stated that working with Carlyle will be a “career highlight.” He praised the actor’s ability to bring power and depth to his roles, keeping viewers on the edge of their seats .

Martin Compston has also shared his excitement about returning. He described the show as a “job of a lifetime” and mentioned that he and his co-stars have become close friends over the years . He revealed that the scripts are fantastic and are already “a proper page turner” .
Adrian Dunbar expressed his joy at getting the team back together, and Vicky McClure said she “can’t wait to work with Jed, Martin and Adrian again” .
