Born into the celebrated Mitford family in 1910 and married at 18 to Bryan Guinness, Diana Mosley was part of a sparkling society circle which included the leading artists and intellectuals of the time. Evelyn Waugh dedicated Vile Bodies to her. Then, at the age of 22, she fell in love with Oswald Mosley and committed her life to his ideas. In Germany she was a friend to Hitler and Goebbels. By 1940 she was in a dmap cell in Holloway prison. Drawing on fresh interviews with Diana, whose views are as contrversial today as they were then, Dalley has created a revealing biography of the wife of one of the most hated politicians of the century.
