Agatha Christie (1890–1976) was an English crime novelist, short-story writer, and playwright. Known as the "Queen of Crime," she is the best-selling novelist of all time, with her works having sold over two billion copies worldwide. Her prolific career spanned over fifty years and included 66 detective novels and 14 short-story collections.
Christie's genius lay in her ability to craft incredibly clever and complex plots, often using misdirection and psychological insights to lead readers astray. She created two of detective fiction's most beloved and enduring characters: the eccentric Belgian detective Hercule Poirot, known for his "little grey cells," and the sharp-witted spinster, Miss Jane Marple. Christie's novels continue to be praised for their meticulous plotting, her sharp characterizations, and her ability to invent mysteries that have stood the test of time.
