Written by Anna Symon and starring Wilson as her own grandmother, the BBC miniseries follows the real story of Alison Wilson, a widow who discovers her spy novelist husband lived a double life. Determined to uncover the truth about the man she loved, she soon finds herself at the center of a mystery that proves truth can be stranger than fiction.
Set in 1940s and 1960s London and 1930s India, Alison thinks she is happily married until her husband, Alec, suffers a fatal heart attack. Not long after, the grief-stricken Alison is confronted by a woman claiming to be Alec’s real wife, Gladys (Elizabeth Rider). Then, at the funeral, Alison is approached by Alec’s colleagues, who offer condolences but refer to puzzling aspects of his work and personal life. A woman turns up on the doorstep claiming that she is the real Mrs. Wilson.
Alison is determined to prove the validity of her own marriage – and Alec’s love for her – but is instead led into a world of disturbing secrets. Alison tracks down Alec’s old spymaster and enters the world of secret intelligence, where agents assume identities, pursue careers, fake romances and undergo public humiliations, all in the name of serving their country.
Seized with doubt about the man she thought she knew, Alison is determined to find out who Alec really was, while keeping her discoveries secret from her sons, who have nothing but happy memories of their father.
Keeley Hawes (“Durrells in Corfu”) and Iain Glen (“Downton Abbey,” “Game of Thrones”) co-star as Dorothy Wick and Alec Wilson, respectively.
