Klaus Fuchs was perhaps the most dangerous spy in wartime Britain. He passed vital information to the Russians, saving them ten years in creating their A-bomb, and severely damaged relations between the Western allies.
Fuchs fled Nazi Germany and came to Britain in 1933. He was naturalised, got a job as a physicist and joined the British-American programme to build the atom bomb. To his colleagues he seemed more English than the English and his patriotism was never questioned as he rose to become Head of the Theoretical Physics Division at Harwell. He was finally uncovered in 1950 and sentenced to 14 years in prison.
Norman Moss pieces together the story of Fuchs..... from his own confession and from the recollection of his friends and colleagues.
