Agatha Christie is the best-selling author of all time. She has sold over 2 billion novels worldwide and has been translated into more languages than any other single writer.

Born on 15 September 1890 in Devon, England, her career spanned six decades in which time she published 80 novels and short story collections and 19 plays. Her first novel, The Mysterious Affair at Styles published in 1920, was written as a result of a challenge from her sister. In it she would introduce to the world Hercule Poirot, one of the most famous fictional characters of all time. Poirot would appear in over 80 novels and short stories. Nine years later Agatha created Miss Marple - a spinster sleuth who would become so popular she would rival Poirot in the nation's affections.

Her writing won her many fans including the royal family. When Queen Mary was approaching her 80th birthday, the BBC asked how she would want them to celebrate it. She requested a new Christie play! Three Blind Mice was duly written for the radio; it would later be adapted into The Mousetrap and become the longest continuously running play in history.

Although best known for her detective fiction, Christie also wrote a number of books that give us insight into her world. Her autobiography, published the year after her death provides a full, and often humorous, account of her life and Come, Tell Me How You Live chronicles her travels as the wife of a world famous archaeologist, on digs in the Middle East.

Agatha Christie had a truly remarkable life; she was a very private lady though her love of travel and archaeology shines through in her work. Her most famous novel Murder on the Orient Express celebrates its 75th anniversary in 2009 and was inspired by her own travels on the train, when she too became stranded due to weather.

After a hugely successful career and a very happy life Agatha died peacefully on 12 January 1976.

Agatha Christie's 'most absorbing mystery' - her own autobiography, with new exclusive CD containing newly discovered priceless recordings of Agatha dictating excerpts from more than 40 years ago. Over the three decades since her death on 12 January 1976, many of Agatha Christie's readers and reviewers have maintained that her most compelling book is probably still her least well-known. Her candid Autobiography, written mainly in the 1960s, modestly ignores the fact that Agatha had become the best-selling novelist in history and concentrates on her fascinating private life. From early childhood at the end of the 19th century, through two marriages and two World Wars, and her experiences both as a writer and on archaeological expeditions with her second husband, Max Mallowan, Agatha shares the details of her varied and sometimes complex life with real passion and openness. Then, in 2008, Agatha Christie's grandson made a remarkable discovery. While clearing out her old house in preparation for its opening to the public, Greenway in Devon, a box of old tape reels was found to contain the recordings of Agatha dictating her Autobiography for her typist. These remarkable recordings are not only an amazingly rare example of Agatha's voice, but they also partly explain the engaging nature of her Autobiography - for they reveal the normally reclusive Agatha telling her own story in a lively, spontaneous and often conspiratorial way, whose passion in talking about her life is captured in the printed Autobiography. Now this new edition comes complete with a CD of highlights from these priceless tapes, giving Agatha Christie's millions of fans the opportunity to hear the Queen of Crime's story in her own words, and rediscover her remarkable full story in this special edition of her book, which is newly introduced by Mathew Prichard, the grandson who discovered the tapes.
