Bernard Samson must uncover the truth about his wife Fiona's defection while navigating a dangerous mission in Poland. Bernard is struggling to reconcile his personal life with the questions surrounding his wife Fiona's apparent defection to the East. His superiors, particularly Dicky Cruyer, seem to be withholding information as they jockey for power, while Bernard is dispatched on a clandestine mission to Poland. The narrative framework appears to follow Bernard's perspective as he grapples with uncertainty and betrayal.

The novel is the second in Len Deighton's FAITH, HOPE and CHARITY trilogy, continuing the narrative of Bernard Samson. The premise sets up a complex espionage plot centered on personal betrayal and political maneuvering, characteristic of Deighton's spy thrillers. The inclusion of new introductory material from both the author and the cover designer suggests a renewed interest in the series and its historical context. The narrative likely focuses on intricate plotting and the psychological toll of espionage on its protagonist.
