Agatha Christie was not only the biggest selling writer 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.

H R F Keating, a crime novelist and respected reviewer of crime fiction, brought together a dozen distinguished writers from both sides of the Atlantic to throw light on this double mystery. Some analyse the art itself; some explain the reasons for her success, not just the books, but also in film and theatre.

The approaches are penetrating, affectionate, enthusiastic, analytical, funny - even critical. Together, they give an almost unique insight into the life and work of the First Lady of Crime.
