When is the new season of ‘Endeavour’ on?

Shaun Evans is back as the young Endeavour Morse in a fifth season of Endeavour.

The Inspector Morse prequel series launched in 2012 and last year celebrated the 30th anniversary of Morse on ITV.

Set in 1968, the new season begins with Morse having finally passed his Sergeant’s exams just as Oxford City Police merges into Thames Valley Constabulary creating uncertainty for everyone at Cowley CID. And despite Joan Thursday (Sara Vickers) return to Oxford, much also remains unresolved following her disappearance the previous year and Endeavour’s unexpected proposal.

Six new feature-length crime mysteries are currently airing on ITV at 8pm on Sunday nights in the UK.

Watch a clip:

Roger Allam (The Missing) returns as Morse’s mentor, Detective Inspector Fred Thursday, alongside Anton Lesser (The Crown) as Chief Superintendent Reginald Bright, Dakota Blue Richards (Skins) as WPC Shirley Trewlove, Sean Rigby (Gunpowder) as Sergeant Jim Strange, James Bradshaw (Primeval) as Dr. Max DeBryn, Caroline O’Neil (Last Tango In Halifax) as Win Thursday, and Abigail Thaw (I Want My Wife Back) as Dorothea Frazil.

Season 5 will also introduce Poldark actor Lewis Peek as new recruit Detective Constable George Fancy, whom Morse is reluctantly tasked with mentoring.

Guest stars will include Donald Sumpter (Game Of Thrones), Phil Daniels (New Tricks), Emma Rigby (Prisoners’ Wives), Steve Elder (Apple Tree Yard) and Robin Weaver (Call The Midwife).

Here’s the story synopsis for the season opener, ‘Muse’: “Past and present collide in Oxford, as the auction of a priceless Faberge Egg gets underway at Lonsdale College. It soon attracts the attention of an infamous international thief – and consequently the newly christened Thames Valley Constabulary – as Endeavour investigates a failed burglary attempt.

“However, they soon have a bigger case to solve, as the gruesome death of a known gangster threatens to expose the growing threat of underworld Oxford. But when a Lonsdale don connected to the auction is murdered in a similarly grisly way, Endeavour begins to suspect the seemingly separate cases may be somehow connected. When the organiser of the auction also meets a bloodthirsty end, he’s convinced. The hunt is underway to find a ruthless and violent serial killer, and track down the next victim before it’s too late.

“Meanwhile, newly-promoted Endeavour struggles with his role as he’s forced to mentor young detective constable George Fancy, and a surprise reappearance opens up old wounds.”

Season 4 is available now on DVD.

The new season will air in the US later this year on Masterpiece on PBS.
