The classic story of one of the twentieth century's most extraordinary families.

Among the six daughters and one son born to David, second Lord Redesdale, and his wife Sydney were Nancy, the novelist and historian; Diana, who married fascist leader Sir Oswald Mosley; Unity, friend of Hitler; Jessica, who became a communist and then an investigative journalist; and Deborah, Duchess of Devonshire and mistress of Chatsworth.

'The Mitford Girls,' as John Betjeman called them, were one of the twentieth century's most controversial families; said to be always either in shrieks of laughter or floods of tears, they were glamorous, romantic and - especially in politics - extreme. Yet the teasing, often bordering on cruelty, the flamboyant contrasts and the violent disagreements, hid a powerful affection, subtle likenesses in character, and a powerful underlying unity.
