Beginning in 1946, when Victor Gregg was demobbed after the end of the Second World War and deposited in London Paddington, Soldier, Spy is the story of a soldier returning to civilian life and all the challenges it entails. Facing a new and ever-changing London, a shifting political landscape and plenty of opportunities to make a few bob, repairing the bomb damage and doing construction work on the Festival of Britain site, Vic moves from one job and pastime to the next, becoming by turns cyclist, builder, decorator, trade union official, Communist Party member and long-distance lorry driver. Finally he is offered ‘a nice clean job’ as chauffeur to the chairman of the Moscow Narodny Bank in which he will be able to return home to his wife and children every night. However, there is more to his new employers than meets the eye, and it is not long before his wartime work with the Long Range Desert group catches up with him in the form of an approach from the security services. Lured by the excitement his postwar life has lacked, Vic adds spy to his roster of employments, risking everything in the process.
