A fourth series will be filmed next year, according to Radio Times.
The series looks set to conclude with a one-part adaptation of Henning Mankell’s novel The White Lioness and a two-parter based on his final book The Troubled Man.
Sources at the BBC and independent producers Left Bank Pictures confirmed that both parties are confident next year will see the filming begin.
The third series was filmed in 2011 and aired in Australia in November 2012. At the time it was tipped to end in 2013.
The series, which previously featured Tom Hiddleston amongst the cast, has won six BAFTAs including Best Drama Series.
