Part One: 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 the police – when a failed burglary attempt is reported. However, they soon have a bigger case to solve, as a series of gruesome deaths have Morse and Thursday searching for a serial killer. Meanwhile, newly-promoted Endeavour struggles with his role as he's forced to mentor young detective constable George Fancy.
Part Two: Cartouche
Hollywood glamour comes to Oxford as the stars of a horror movie begin filming in the city. Meanwhile, the unexplained poisoning of a former detective sergeant leads Endeavour and Thursday to a local cinema, which is playing host to the film's stars in a special event. While Thursday fears a link to growing unrest in Oxford's underworld, the case takes a turn when the cinema's organist is also dramatically poisoned. The film's star is convinced a mysterious Egyptian curse is to blame, and Endeavour and Thursday find themselves uncovering long-kept secrets and a revenge plot determined to expose the truth behind a hero's past.
Masterpiece: Endeavour Season 5, Friday beginning at 9 p.m. on PBS 6.
