That Woman by Anne Sebba

Anne Sebba recasts the most famous love story of the age as 'a tale of gothic darkness with a Faustian pact at its core'. Drawing upon previously unseen sources, including declassified government files and letters between Wallis Simpson and her second husband (a correspondence that continued after she began her relationship with the Duke of Windsor), she offers fresh insights into the character and motivations of one of the most vilified women of her generation.
