When Anne Glenconner wrote Lady in Waiting: My Extraordinary Life in the Shadow of the Crown, she had no idea that the book -- about her life as Princess Margaret's lady in waiting for over 30 years -- would become an international runaway hit and launch a new chapter of her life. Since then, she has turned her hand to murder mystery and written two books based on two of her favourite stomping grounds, Mustique and Holkham. Moderator: Francesca Beauman
