London, 1941. The city is in blackout, besieged by nightly air raids from Germany. Two strangers are about to meet. Between them they may alter the course of the war.

Although the Blitz has united the nation, there is an enemy hiding in plain sight. A group of British citizens is gathering secret information to aid Hitler’s war machine. At the heart of this treachery is Jack Hoste, who also has a personal mission: to locate and recruit the most dangerous Nazi agent in the country, Marita Pardoe.

Hoste soon receives a promising lead. Amy Strallen, who works in a Mayfair marriage bureau, was once close to Marita. Her life is a world away from the machinations of Nazi sympathisers, but when Hoste pays a visit to Amy’s office, everything changes in a heartbeat.

Breathtakingly tense and trip-wired with surprises, 'Our Friends in Berlin' is inspired by true events. It is a story about deception and loyalty – and about people in love who watch each other as closely as spies.
