Atomic Spy shows the real Klaus Fuchs - German by birth, British by naturalisation, Communist by belief, convicted of treason in 1950 for handing over plutonium bomb designs to the Soviets. His extraordinary life is a cautionary tale about morality and a classic anti-hero story. With thrilling detail from never-before-seen archives it places readers in the Germany of an ascendant Nazi party; the British university classroom of Max Born; a British internment camp in Canada; the secret laboratories of Los Alamos; and Eastern Germany at the height of the Cold War.
