BBC America has revealed the first official image from series four of Luther, and as you can see, the detective is looking a lot more casual than normal as he roughs up a suspect…at least, that’s who we think it is! Based on how series three ended, Luther may be operating on his own accord when the series returns, and some new plot details have also been revealed.

“Luther’s back,” reads the synopsis released with the image. “Pitted against his most chilling adversary yet, haunted by the ghosts of his past and hell-bent on retribution, he’s drawn into a terrifyingly complex case that pushes him closer to the edge than he’s ever been.”

Series four of Luther was written by creator Neil Cross and will be directed by Sam Miller (No Good Deed). Along with Idris Elba, the two-part special stars Rose Leslie (Game of Thrones), Laura Haddock (Guardians of the Galaxy), Darren Boyd (Fortitude), John Heffernan (Jonathan Strange & Mr Norrell) and Patrick Malahide (Game of Thrones), with Michael Smiley and Dermot Crowley returning as Benny Silver and DSU Martin Schenk respectively.

With any luck, a trailer for the series will hopefully be released to accompany this first look image at some point as Luther is set to premiere on the BBC a little later this Autumn.
