A documentary entitled Behind The Scenes: Agatha Christie's Marple was shown on ITV3 after the final episode of the first series. The documentary is available on the DVD release of the first series.
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.
