Janet Morgan's definitive and authorised biography of Agatha Christie, with a new retrospective foreword by the author. Agatha Christie (1890-1976), the world's bestselling author, is a public institution. Her creations, Hercule Poirot and Miss Marple, have become fiction's most legendary sleuths and her ingenuity has captured the imagination of generations of readers. But although she lived to a great age and was prolific, she remained elusively shy and determinedly private. Given sole access to family papers and other protected material, Janet Morgan's definitive biography unravels Agatha Christie's life, work and relationships, creating a revealing and faithfully honest portrait. The book has delighted readers of Christie's detective stories for more than 30 years with its clear view of her career and personality, and this edition includes a new foreword by the author reflecting on the longevity of Agatha Christie's extraordinary success and popularity.
