Elly Conway, an introverted spy novelist, has almost finished her fifth book about Aubrey Argylle, the eponymous character of the Argylle series, but suffers from writer's block after feedback from her mother, Ruth. On a train journey to visit Ruth and her father, Barry, Elly is saved from an ambush by an actual spy, Aidan Wilde, who explains to her that a devious organization, known as the Division, has targeted her because her novels seemingly predict their future. Aidan travels with Elly to England, hoping that her next chapter will reveal how to stop the Division. In London, the duo searches for a "Masterkey"[b] that would help expose the Division referenced in Elly's novels. Suspecting Aidan wants to kill her too, Elly calls her parents for help. As they arrive, Aidan reveals that her parents are operatives of the Division, forcing him and Elly to fend them off before fleeing. Escaping to France, Aidan and former CIA deputy director Alfie Solomon reveal that Argylle is not entirely fictional: Elly is in fact agent Rachel Kylle ("Argylle" seemingly having been derived from "R. Kylle"), who was captured and brainwashed by the Division five years earlier and made to believe that Dr. Margaret Vogeler (Ruth) and Director Ritter (Barry) were her parents. Elly put her suppressed memories, in modified form, into her novels; Aidan resurfaces as one of her characters, Wyatt, while Alfie reappears as her cat. With the latest Argylle novel, Rachel was about to reveal the whereabouts of the Masterkey to the world
