Oxford\'s brilliant young detective opens the casebook on a brand new set of perilous murder mysteries as Endeavour returns. Barely a fortnight has passed since the dramatic finale of series three, and we find Oxford\'s finest picking up the pieces of their lives. Endeavour waits to hear the results of his Sergeant\'s exam, self-medicating to numb his heartache but whisky will only get a man so far. With the summer of 1967 fading into autumn, and the Cold War on the rise, Endeavour and senior officer DI Thursday soon find themselves plunged into their most baffling and darkly terrifying investigations to date.
