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.
