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; others explain the reasons for her success --- not just the books, but also in film and theater.
