In this biography of the Duchess of Windsor, Higham claims to have uncovered new facts about the abdication crisis and her life claiming that his researches have revealed a complex, brilliant and dangerous woman who may have threatened the security and survival of Britain during the whole period of Nazi dominance. The author traces the path from her early spying activities in China in the 1920s through to the following decade suggesting that she made moves to bring about the fall of Britain to Hitler and that information vital to British national security was passed to Nazi leaders. He reveals the many meetings and contacts with high-ranking leaders of the German and Italian Fascist parties, including an account of the meeting between the Duke of Windsor and Hitler. He claims that the sinister activities of the Windsors continued during the Duke's wartime governorship of the Bahamas and that the Duke was implicated in the murder of Sir Harry Oakes unveiling both the murderer's identity and details of the cover-up operation. Higham reveals many new facts about the Duchess's role in the abdication saga, which suggest both an initial lack of personal commitment to Edward and a campaign to dissuade him from abdication.
