Endeavour, recruited by his old college mentor Felix Lorimer to look into the safety of his estranged younger wife Nina, contemplates his police career as well as having to contend with unexpected strife in his personal life.

April 1967. As spring blooms, the death of artist Simon Hallward in a horrendous house‐fire leaves Oxford City Police baffled as to the cause of the blaze. When a young housewife dies, seemingly of the same mysterious ‘tummy bug’ that has seen half of Chief Superintendent Bright’s men go on Sick Leave, DC Endeavour Morse’s investigation leads him to an inner‐city supermarket, Richardson's, owned by a wealthy family of the same name, descended from a line of Quakers.

As a Russian academic prepares to do battle with the Joint Computing Nexus (JCN or Jason for short) in a game of chess, the Cold War is played out on a chequered field and Endeavour and Thursday are plunged into their most perilous, baffling and darkly terrifying case to date. Throwing himself into his work to mask the heartache of Joan's departure, Endeavour is quickly consumed by his duties when one of the research team is found drowned near Magdalen Bridge.

Is there more to the deaths than meets the eye?
The so called ‘permissive society' comes under the spotlight as Endeavour is tasked with protecting conservative social activist, Joy Pettybon, after she receives a death threat while visiting Oxford to promote her ‘Keep Britain Decent' campaign. Also staying near Oxford and recording their new album are a band called The Wildwood and their manager Ralph Spender, who is desperate to maintain their squeaky-clean image in the media spotlight. However, their harmony is disrupted when the body of local brickie, Barry Finch, is discovered in the middle of Oxford and it transpires that Finch was working at Maplewick Hall, where they band are staying, before he died. Delving into the social revolution of the time, Endeavour finds himself caught in the crossfire of bitter liberalising forces and deep reactionary conservatism both fighting for the consciences of the British people in 1967.
