Book excerpt: From the Back Cover: A Shy and retiring woman who began to write "in order to avoid having to talk to people," Agatha Christies produced her first detective novel at age twenty-six on a dare from her sister. She went on to author seventy-eight crime novels and short-story collections that have sold over two billion copies in more than 100 languages, making her the bestselling author of all time (Shakespeare is second). Published in commemoration of the 100th anniversary of her birth, The Life and Crimes of Agatha Christie is a comprehensive, fully illustrated guide to the lifework of this remarkable woman and an in-depth portrait of the world in which she lived. In this insightful biography, acclaimed author Charles Osborne examines not only Christie's numerous murder mysteries and crime thrillers but also her plays, poetry, nonfiction, stories for children, the films based on her works, and the six semiautobiographical "romantic" novels that she wrote under the pseudonym Mary Westmacott. Osborne also explores the creation of Christie's much loved sleuths-the egotistical and eccentric Hercule Poirot and the shrewd spinster Miss Jane Marple. From classics of detection like Murder on the Orient Express, Ten Little Indians, and her record-breaking play The Mousetrap to her mysterious 1926 "disappearance" and her life in the Middle East as an assistant to her archaeologist husband, this fascinating and authoritative biography reveals the life and work of the woman who ushered in the golden age of crime fiction and who remains the world's most popular mystery writer.
