Anna Maxwell Martin returns to Line of Duty as DCS Patricia Carmichael this Sunday

As excitement builds in this latest series of Line of Duty, everything may be about to change with a familiar (and unwelcome to some) face returning to the show. The BBC is keeping details very much under wraps, but we do know this:

Viewers will remember no-nonsense DCS Carmichael from series five, where she was brought in as an independent investigator from AC-3 after suspicions mounted over the integrity of Superintendent Ted Hastings. Now with Ted’s forced retirement looming, is Carmichael in position to take control? And with the restructure of the anti-corruption units, is this the end of AC-12?

Anna Maxwell Martin says: “Pat’s back, I can’t remember what she’s doing there, nor would I be allowed to blab, but suffice to say she’s got some new clobber and she’s ready to bust some balls.”

Of course where would fans of the show be without surprises and expect this to be a major topic in the next Obsessed with… podcast. Anna Maxwell Martin returns was very much a theme for part of this mornings Zoe Ball Breakfast Show on BBC Radio 2 this morning. Martin chatted about a number of things (including the play Constellations) and how thrilled she was to be asked back to the role. She can also be seen on Netflix in The Irregulars season 1. You can catch the conversation on BBC Sounds, around two hours through. The full BBC announcement is also available.
