The longest serving spy for the British Secret Intelligence Service (MI6), Charles Howard Ellis helped set up the Office of Strategic Services (OSS), now known as the Central Intelligence Agency (CIA), as well as the Australian Secret Intelligence Service (ASIS). At one point in the 1940s, he was considered one of the top three secret agents in MI6 and controlled its activities, as one journalist put it, 'for half the world'. But in the 1980s journalist Chapman Pincher and retired MI5 intelligence officer Peter 'Spycatcher' Wright posthumously accused Ellis of having operated as a 'triple agent' for Nazi Germany and the Soviet Union. In 1965, while under interrogation in London, Ellis had allegedly made a partial confession that he had worked for the Nazis. However, Pincher's and Wright's accusations against Ellis have never been comprehensively proven. Was Ellis guilty or was an innocent man framed? By confessing, did he take the fall for someone else?
