Diana Mosley was one of the most spectral and controversial figures of recent years. Born in 1910, she was considered the most beautiful and the smartest of the six Mitford sisters. At 18, she married Bryan Guinness, a member of the brewery, with whom she had two sons. After four years, she left him for the fascist leader, Oswald Mosley, and defined herself as his mistress - an action that shocked her family and caused a scandal in society. In 1933, she took her sister, Unity, to Germany and soon they met the new German leader, Adolf Hitler. Diana became so close to him that when she married Mosley in 1936, the ceremony took place in Goebbels' living room with Hitler as the honored guest. She continued to visit Hitler until a month before the outbreak of the war and, later, for many years, refused to believe in the reality of the Holocaust. This fascinating book is a portrait of both an extraordinary personality and the strange and horrific world of political extremism in the 1930s.
