Agatha Christie’s books are still some of the best selling mystery books of all time, despite the fact that she died over 40 years ago. Christie wrote over 60 mystery novels, and is one of the most popular and best loved writers of all time. She is best known for her two fictional characters of Miss Marple and Hercule Poirot. Most of her books have been filmed or adapted into plays, including the Mousetrap, which has become the world’s longest running play of any kind. Although Christie’s books very much capture the often glamorous world of the 1920s and 30s, she has been a major influence on many of today’s best selling mystery writers. Many of her titles are familiar to those who have never even read a mystery, such as Murder On the Orient Express, and Death On the Nile.
