In Series four, barely a fortnight has passed since the events depicted in the series three finale, and we find Oxford’s finest picking up the pieces of their lives, both personal and professional. Endeavour waits to hear the result of his Sergeant’s Exam, and self-medicates to numb his heartache, but whisky and Tannhauser will only get a man so far. While Thursday and Win deal with their own sense of grief. Their home is empty, Sam gone to the Army and Joan… Who knows where? The stories that remain will take Endeavour and Thursday, together with the rest of Oxford’s Finest, into places hitherto unexplored – the worlds of 1960s pop; Doctors and Nurses; and an exploration of the English pastoral.
