From Poirot to Miss Marple, from The Mousetrap to Witness for the Prosecution, this a fascinating look at the life and work of Agatha Christie, the world's most successful and popular crime writer. Agatha Christie was not only the most successful author of detective stories the world has ever known, she was also a mystery in herself, giving only the rarest interviews declining absolutely to become any sort of public figure and a mystery, too, in the manner in which she achieved her astonishing success. Distinguished crime novelist and acclaimed critic H. R. F. Keating brings together a dozen noted writers from both sides of the Atlantic to throw light on the ever-intriguing Dame Agatha. Some essays analyze Christie's art itself, some explain the reasons for her success not just the books, but also in film and theatre. The myriad of critical angles explored here are penetrating, affectionate, enthusiastic, analytical, and even funny. Together, they give an almost unique insight into the life and work of the First Lady of Crime. Includes essays by Sophie Hannah, H. R. F. Keating, Elizabeth Walter, Julian Symons, Edmund Crispin, Michael Gilbert, Emma Lathen, Colin Watson, Celia Fremlin, Dorothy B. Hughes, J. C. Trewin, Philip Jenkins on, William Weaver, and Christianna Brand.
