Editor's Take:

No novelist has sold more books than Agatha Christie; by some estimates only Shakespeare and the Bible have outsold her. She created two of crime fiction's most beloved detectives: the fastidious Belgian Hercule Poirot and the shrewd village spinster Miss Marple. Her plots are famous for their clever twists and fair play, giving readers every clue needed to solve the mystery. Her play The Mousetrap has been running in London's West End since 1952, the longest initial run of any play in history. She drew on her knowledge of poisons, gained working in a hospital pharmacy during the First World War.
