"The greater the spy, the bigger the lie."

Argylle

When the plots of reclusive author Elly Conway's fictional espionage novels begin to mirror the covert actions of a real-life spy organization, quiet evenings at home become a thing of the past. Accompanied by her cat Alfie and Aidan, a cat-allergic spy, Elly races across the world to stay one step ahead of the killers as the line between Conway's fictional world and her real one begins to blur.
