Where did Britain’s grande dame of mystery go to escape the pressures of fame? AGATHA CHRISTIE’S GARDEN explores the writer’s life through a tour of Greenway, her holiday home in Devon which she purchased in 1938. A 30-acre Georgian retreat, it was the place where Christie could shed her public persona and truly express herself. Pam Ferris ( Rosemary & Thyme ) serves as guide, presenting exclusive interviews with author P.D. James, as well as with Christie’s grandson, biographer and other experts who illuminate the inner character of this complex woman.
