Endeavour to return in 2017.
Successful detective drama Endeavour, has been recommissioned for a fourth series, ITV has confirmed.
Produced by Mammoth Screen, Endeavour stars Shaun Evans (The Scandalous Lady W) as the young Morse, in a prequel to the popular Inspector Morse series.

As Series IV (1967 Vol.2) resumes, barely a fortnight has passed since the events depicted in the series III finale. Endeavour waits to hear the result of his Sergeant’s Exam, and self-medicates to numb his heartache, but whisky and Tännhauser will only get a man so far.  While Thursday and Win deal with their own sense of grief.  Their home is empty, Sam gone to the Army and Joan… Who knows where?
The summer of 1967 is on the turn. Midsummer has been and gone but in Lovelace College a team of boffins is about to unveil a ‘thinking machine’ that will challenge the Soviets, and plunge Endeavour and Thursday into their most perilous, baffling and darkly terrifying case to date.  White Heat.  Cold War.  And an immortal game that will cast the life of a friend into the hazard.
The stories that remain will take Endeavour and Thursday, together with the rest of Oxford’s Finest, into places hitherto unexplored – the worlds of 1960s pop; Doctors and Nurses; and an exploration of the English pastoral.
