Who was the Russian spy working under Oppenheimer to build the atomic bomb? Why was it so dangerous to be a communist in Nazi Germany? And how did a young science prodigy become one of the most notorious spies in history?

Klaus Fuchs was born into a left-wing family at the beginning of the 20th century. Vehemently opposed to the fascist politics of his German homeland during the 1930s, Fuchs flees Hitler's repressive state and finds himself caught up in the horrors of World War Two. When a group of ambitious communists reach out to save him, his life is changed forever. This is the story of the communist spy who infiltrated the Manhattan Project.

Listen as Gordon and David begin to tell the fascinating tale of Klaus Fuchs, the atomic spy.
