The extraordinary story behind A Very British Scandal, starring Claire Foy and Paul Bettany ?Margaret was debutante of the year, the beautiful fairy-tale heiress immortalised in Cole Porter's 'You're The Top' - who ended up penniless and ostracised from her own family. Legal actions coloured her life - her divorce from the Duke of Argyll was one of the longest, costliest and most notorious in British legal history. Her diaries, and photographs of her with an anonymous naked man, were used in evidence. This sparkling biography draws on exclusive interviews with the late Duchess to lift the lid off her extraordinary story, and her scandalous lifestyle. The Duchess Who Dared is a fascinating chronicle of a complex, charming and surprisingly modern woman.
