1967 is for Endeavour ‘perhaps the end of the beginning.' Change is abroad in the world and not even the city of dreaming spires can escape its influence. Change for Endeavour, and those most dear to him – personally and professionally. Departures and arrivals. Entrances and exits. Our next quartet of mysteries will take the audience on a psychedelic Summer of Love fairground ride, filled with twists and turns, shrieks and scares. In particular, one encounter at a certain stately home will echo down the years, and have consequences that not even Endeavour Morse could have foreseen. The only constant is death… And Green Shield Stamps.
