The personal lives of the British Royals were successfully kept out of the public eye by mutual agreement of the press and royal family, but this all changed in 1936 when King Edward VIII abdicated the throne and spurned his responsibility for the sake of the glamorous American socialite and divorcee, Wallis Simpson. During the Second World War, though the world's press focused on the far more public conflict tearing nations apart, the royal romance provided light relief for the British public. But this relationship had a darker side, and in 'Princes at War', Deborah Cadbury reveals evidence that the Duke and Duchess of Windsor colluded with Hitler to take back the British throne from Edward's younger brother, King George VI, should Germany prevail in the War.
