Winter 1981. Poland teeters on the brink of collapse, and the CIA seeks to hasten its demise. They enlist MI6, but exclude the Warsaw station, raising suspicions. Agent Thomas Dylan is dispatched from Moscow, only to find himself caught in a web of bullets and betrayals alongside his wife, Julia.
As American agents vanish near snowy Polish lakes, a terrified sailor defects, and a peasant claims to possess a lost crown, Dylan must untangle a deadly conspiracy. From the Volga's icy grip to sleepy Cornish villages, Coincidence of Spies weaves a tale of political intrigue, where the line between ally and enemy blurs with every twist. Will Dylan survive the coincidence, or become another pawn in a game of shadows?
