Author Biography: Who Was Agatha Christie?

Born in Torquay, England, in 1890, Agatha Christie grew up in a middle-class family with a love for storytelling. Despite being largely self-educated, her imaginative flair led her to writing early poems and stories.

Her career breakthrough came in 1920 with The Mysterious Affair at Styles, which introduced Hercule Poirot—a Belgian detective who would later become one of the most enduring figures in crime literature.

Over her six-decade career, Christie produced 66 detective novels, 14 short-story collections, and the world’s longest-running play, The Mousetrap.

Expert Commentary (The Guardian, 2024): “Christie’s genius lies not only in her ingenious plots but in her deep psychological understanding of human motives—greed, jealousy, and revenge.”
