EDITORIAL REVIEW: A new-look printing of Agatha Christie's 'most absorbing mystery' to mark the 25th anniversary of her death. Agatha Christie died on 12 January 1976, having become the best-selling novelist in history. Her autobiography, published in 1977 a year after her death, tells of her fascinating private life, from early childhood through two marriages and two World Wars, and her experiences both as a writer and on archaeological expeditions with her second husband, Max Mallowan. Not only does the book reveal the true genius of her legendary success, but the story is vividly told and as captivating as one of her novels.
