When Agatha Christie died in 1976, at age eighty-five, she had become the world's most popular author. At the end of 2004, following the death of Christie's daughter, Rosalind, a remarkable legacy was revealed: seventy-three handwritten volumes of notes, lists, and drafts outlining all her plans for her many books, plays, and stories. Buried in this treasure trove, all in the beloved author's unmistakable handwriting, are revelations about her famous books that will fascinate anyone who has ever read or watched an Agatha Christie story.

Full of details she was too modest to reveal in her own autobiography, this remarkable book includes a wealth of excerpts and pages reproduced directly from the notbookss and her letters—plus, two complete, recently discovered Hercule Poirot short stories never before published.
