Grand Affair [Paperback]

A British aristocrat. An American heiress. A scandal that rocked two continents. This is the true story of the Duchess of Marlborough's affair with the dashing Lord Castlerosse in 1920s London — a liaison so brazen it threatened to topple one of England's great dynasties. Author Charlotte Mosley pulls from private letters, society columns, and family archives to reconstruct a world of champagne lunches, country house weekends, and increasingly reckless passion. The Duchess risked everything: her fortune, her children, her place in society. Castlerosse, charming and penniless, had nothing to lose. What unfolds is a portrait of desire colliding with duty in an era when divorce could still destroy you. For readers who loved The Bolter or can't get enough of high-society scandal with real stakes.
