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.

agatha christie became generally recognized in 1926, after the publishing of her novel "the murder of roger ackroyd". it is still considered her masterpiece.

when agatha cristie got tired of hercule poirot she invented miss mar-pie, a deceptively mild old lady with her own method of investigation.
