'A gripping account of the cloak and dagger game played in Berlin and beyond by Britain's shadow warriors. A knife-edge Cold War showdown. A game of secrets, masterfully told.' - Damien Lewis, Sunday Times No. 1 Bestselling Author

The British Commanders'-in-Chief Mission to the Soviet Forces in Germany, better known as BRIXMIS, was arguably the most successful and enduring intelligence organisation of the whole Cold War. Its three-man teams maintained a permanent presence behind the Iron Curtain, patrolling East German soil every single day from 1946 until the fall of the Berlin Wall changed the face of post-war Europe.

In a follow-up to The Deadly Game, Will Britten, a career Military Intelligence Officer, treats us to a fresh, and in places hard-hitting look at his experience as one of the last generations of Cold War warriors. Over the Wall details reconnaissance missions in the depths of the DDR, targeting by Stasi surveillance teams, and fascinating personal contacts with 'the enemy'. Beyond this, he puts forward the shocking proposition that Moscow had almost certainly compromised BRIXMIS through their own agents operating within the wide US military system.

Providing a rare insight into the activities of the GRU-staffed Soviet military teams deployed reciprocally in West Germany, Over the Wall ultimately poses an intriguing question: in the final balance whose missions were operationally more effective?
