The memo landed on Kim Philby's desk in Washington, DC, in July 1950.
Three months later, Bruno Pontecorvo, a physicist at Harwell, Britain's atomic energy lab, disappeared without a trace.
When he re-surfaced six years later, he was on the other side of the Iron Curtain.
One of the most brilliant scientists of his generation, Pontecorvo was privy to many secrets: he had worked on the Anglo-Canadian arm of the Manhattan Project, and quietly discovered a way to find the uranium coveted by nuclear powers.
Yet when he disappeared MI5 insisted he was not a threat.
Now, based on unprecedented access to archives, letters, surviving family members and scientists, award-winning writer and physics professor Frank Close exposes the truth about a man irrevocably marked by the advent of the atomic age and the Cold War.
