But what we – or anyone, for that matter – couldn’t have predicted, was the return of one of the series’ most infamous characters: Detective Chief Superintendent Patricia Carmichael, played by none other than Anna Maxwell Martin.

Line Of Duty: a familiar face will be returning to our screens for next week’s episode
