David Somers, Trevor Howard, a former army officer who rose to the ranks of the British Secret Intelligence Service during the Second World War, finds his glittering career cut short after a mission ends in failure. With his active duty behind him, he takes a quiet, almost genteel job cataloguing butterflies at the country house of Nicholas and Jess Fenton, where the clouded yellow—a rare species—becomes a quiet, almost symbolic thread in his day-to-day life.
At the Fenton estate, Somers encounters Sophie Malraux, Jean Simmons, Jess’s niece, and the pair’s initial reserve gives way to a growing attraction that both unsettles and energizes them. Sophie’s presence injects a vulnerable humanity into Somers’s guarded world, and the two begin to lean on each other as the atmosphere around them grows tenser.
Trouble erupts when Hick, Maxwell Reed the local gamekeeper and Jess’s lover, is murdered. The investigation rapidly veers toward Sophie, who is already carrying the weight of a painful past: memories of her parents’ apparent suicides when she was six, a trauma she has spent years suppressing. The accusation lands hard, and the feeling of accusation is intensified by Sophie’s fragile air as she grapples with the consequences of the scandal.
Determined to protect her, Somers uses every shred of his SIS training and his network of contacts to help Sophie elude capture. He finds himself in a tense dance with the authorities and with Willy Shepley, Kenneth More, an SIS agent who becomes a relentless pursuer. The pursuit is breathless and cross-country, drawing them farther from home and deeper into a web of danger and deception.
Their journey finally carries them to Liverpool, where they hope to flee the country by ship. The chase, however, is not just a geographic one; it is layered with secrets that will upend Sophie’s sense of her own history and the loyalties of those around her.
The killer’s identity is finally revealed: Sophie’s uncle, Nicholas Fenton, Barry Jones, is the man behind Hick’s murder. He had also killed Sophie’s parents, a crime tied to the truth that her father was another of Jess’s lovers. The revelation reshapes everything Sophie has believed about her family and her own past, casting a harsh light on the tangled relationships that have shaped her life.
In the dramatic climax, Nicholas chases Sophie onto a warehouse roof. The pursuit ends in a fatal accident as he slips and is struck by a passing train, sealing a grim and inevitable end to the danger that has shadowed them all along. The story closes with Somers and Sophie navigating the aftermath of the revelations, their bond tested but ultimately holding as they step into an uncertain future together.

Following a distinguished but abruptly ended career in the British Secret Intelligence Service, David Somers seeks refuge from his past in the quiet corners of the countryside. He accepts an unassuming position cataloguing butterflies at the estate of Nicholas and Jess Fenton, trading the high-stakes world of espionage for the methodical peace of lepidopterology.

Within this rural retreat, Somers encounters Sophie Malraux, the Fentons’ niece, whose presence introduces a vulnerable humanity to his otherwise solitary existence.
