Agatha Christie celebrations

From Publishing News:

TO mark the seventieth anniversary of the publication of Death on the Nile, one of Agatha Christie's most popular mysteries and one the most successful spin-off films, a week-long celebration of the mystery writer and, in particular, her contribution to archaeology in the Middle East, kicks off on 9 September. A new biography by Laura Thompson, Agatha Christie: An English Mystery - the first full biography for more than 20 years - will be published by Headline to mark the occasion. The biography will draw on interviews with Christie's relatives, including her daughter and grandson, and on private papers, to which Thompson has enjoyed unprecedented access, to reveal "an internal life more complex than her books might suggest".
