Oxford’s brilliant young detective opens the casebook on a brand new set of perilous murder mysteries as Endeavour returns.

Following the dramatic finale of series three, we find Oxford’s finest picking up the pieces of their personal and professional lives. DC Endeavour Morse awaits the result of his Sergeant’s Exam, while DI Fred Thursday and his wife Win struggle to cope with their children flying the nest; Sam gone to the Army and the traumatised Joan… who knows where? But there are even greater challenges to face. The Summer of Love is on the turn, and the Oxford City Police finds itself caught on the frontier of the future; computers, pop music, the National Health, nuclear power, the struggle between old and new played out on the battleground of Oxford. For every force for progress there is malign counterforce, and Endeavour, Thursday and colleagues are plunged into their most perilous, baffling and terrifying cases to date.
