Berlin, 1938. Scottish author Corran Rutherford travels to Germany to deliver lectures about her books and write articles about life under the Third Reich. But beneath this respectable cover lies her true mission: infiltrate the social circle of a high-ranking Luftwaffe officer and gather intelligence for MI6.

Corran steps into a complicated political landscape, a world of hidden loyalties and dangerous secrets. It is a realm in which spymaster Frank Foley is at home. Inside the seemingly innocuous offices of British Passport Control, the routine issuing of visas and passports veils a network of agents connected across Europe. And under the gathering clouds of war and in plain sight of the authorities, Foley uses his mundane role to bend rules and forge lifelines, helping desperate citizens escape persecution.

Inspired by remarkable true events, The Berlin Passport Office is a gripping story of espionage, courage and resistance under the darkening shadow of the Nazi regime.
