Agatha Christie is known all over the world as the Queen of Crime. She wrote 78 detective novels, 19 plays, and 6 romantic novels. Her books have been translated into 103 foreign languages. They are the third best-selling books in the world (after Shakespeare's works and the Bible). Many of her novels and short stories have been filmed. The Mousetrap, her most famous play, is now the longest-running play in history of world theatre.

   Agatha Christie was born at Torquay, Devonshire. She was educated at home and took singing lessons in Paris. She began writing at the end of the First World War. Her first novel, "The Mysterious Affair at Styles" was published in 1920. That was the first appearance of Hercule Poirot, who became one of the most famous private detectives since Sherlock Holmes.
