ITV’s Endeavour finally makes its return, and the channel has kindly released a sneaky look at what fans can expect from the upcoming fifth series.

The series will be back for a new 6-part run (instead of the usual four), following Detective Sergeant Endeavour Morse (Shaun Evans) and Detective Chief Inspector Fred Thursday (Roger Allam) in 1968 Oxford.

Set in 1968, the new series begins with Morse having finally passed his Sergeant’s exams, as Oxford City Police merges into Thames Valley Constabulary. Joan Thursday (Sara Vickers) has returned to Oxford, but much is unresolved following her disappearance the previous year and Endeavour’s unexpected proposal.

Anton Lesser, Dakota Blue Richards, Sean Rigby, James Bradshaw, Caroline O’Neil and Abigail Thaw also star.

Guest stars Robin Weaver, Charlotte Hope, Caroline Goodall, Ellie Haddington, Richard Durden, Dominic Carter, Steve Elder, Lily Lesser and Rebecca Saire were previously confirmed.

Writer Russell Lewis said: “As production begins on Endeavour ’68, many of the global tensions of that most turbulent year have found their way into our six new mysteries. ’67’s Summer of Love seems already a distant memory.

“Dark clouds are gathering at home and abroad as, after almost 100 years, the long history of Oxford City Police comes to an end. A terrible storm is set to blow through the professional and personal lives of newly promoted Detective Sergeant Endeavour Morse and Oxford’s Finest, leaving devastation in its wake.”
