We're sitting in the drawing room of Lady Pamela Hicks' home in Oxfordshire listening intently to Lady Pamela's mesmerising stories. It's just India, Lady Pamela and Lisa the producer who's recording it and putting it all together. We've chosen to have no studio, no formalities just conversation and plenty of tea and cake.

This episode is all about Lady Louis Mountbatten, one of the most intriguing and intelligent debutants of her day, mother to Lady Pamela and grandmother to India. Born Edwina Ashley she was the goddaughter of Edward VII and heiress to a vast fortune. Already very much in the public eye, her wedding to Louis Mountbatten, great grandson of Queen Victoria, in 1922 cemented this powerful couple's place in British society. In episode one of two, Lady Pamela explores her mother's glamorous years of parties and travels, her life and loves, and the way in which the war years changed her from a party-loving socialite to the formidably powerful and intuitive woman she became.
