Sean Evans as the newly promoted Detective Sergeant Endeavour Morse in the “Endeavour” fifth series premiere title “Muse”

The ITV “Inspector Morse” prequel series “Endeavour” is currently filming its fifth series. For American readers, one needs to understand the word series in the British Isles is used in relation to both the season and the entire production.

Shaun Evans, best known for the television series “Whitechapel” and “Silk,” returns to the title role as the newly promoted Detective Sergeant Endeavour Morse.

Schedule to hit British television screens on Sunday, 4 Feb. 2018, the first episode in the 1968-set six-episode run sees the Oxford educated detective sergeant investigating a murder connected with the auction of a priceless Faberge Egg.

Also reprising their roles from previous televised series are actors Roger Allam, Anton Lesser, Sean Rigby and Dakota Blue Richards as Detective Chief Inspector Fred Thursday, Chief Superintendent Reginald Bright, Detective Sergeant Jim Strange and WPC (Woman Police Constable) Shirley Trewlove, respectively.

Historically speaking, while it is politically incorrect to use it today, the job title WPC was commonly used in the British Isles up until 1999 when it was officially discontinued. Despite the discontinuation of ranks such as WPC, older members of the public have been known to keep using the outdated ranks.

Like that seen with the previous four series, the likelihood of their being nods to both the “Inspector Morse” and “Lewis” series should be expected.

The actor in the title role is Shaun Evans, not Sean Evans. Thanks to Twitter user “HoneyBearKelly,” the error was noticed and promptly corrected.
