Series 9 begins in the Spring of 1972 with Morse returning to Castle Gate after taking time away in an effort to manage his troubled relationship with alcohol. But changes coming to CID and an increasing intimacy in Joan and Strange’s relationship promise upheavals both personal and professional for Morse.

Members of their local PBS station can stream series 1-8 leading up to Sunday via the PBS app and online if you happen to have a spare 60+ hours.

Season 9: Episode 3: Exeunt
A series of death notices in the Oxford Mail, each with a distinctive, cryptic message, provides clues to Endeavour’s latest – and final – investigation. Meanwhile, Thursday is under pressure from a familiar face.

From the cobbled streets of Oxford to the criminal underworld of London, mysteries and secrets unfold it’s clear that unsettling ties to an old case set Morse and Thursday on a course that will propel them to the series’ end. The Inspector Morse/Lewis/Endeavour franchise has been at the forefront of cerebral telly for over three decades as John Thaw’s Inspector Morse series premiered in 1987.

When the book closes on Endeavour Morse, rest assured the crossword will be completed and the opera’s last note will sound as the sun sets behind Oxford’s dreaming spires as we say goodbye to the beloved long-running detective series Endeavour when it comes to an end beginning this Sunday through July 2. 🙁
