Endeavour: Muse (ITV 4 Feb 2018, with Sara Vickers)
In season five opener, Muse, it is now 1968 and Morse is newly promoted to Detective Sergeant. The new season in fact 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.
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.
