Dame Agatha Mary Clarissa Christie, known as the 'Queen of Mystery,' was an English writer famed for her 66 detective novels, 14 short story collections, and the world's longest-running play, 'The Mousetrap.' Born on September 15, 1890, in Torquay, England, Christie's literary career blossomed with the creation of Hercule Poirot and Miss Jane Marple, two iconic figures in the crime genre. Her novel 'The Mysterious Affair at Styles' (1920) introduced Poirot, emblematic of her intricate plotting and shrewd character development. Christie's works, compiled in collections such as the 'AGATHA CHRISTIE Premium Collection,' epitomize the classical whodunit style interlaced with ingenious puzzles. A master of the detective novel, Christie's writing is noted for its use of misdirection, red herrings, and surprise denouements, which have captivated readers and popularized the 'Golden Age of Detective Fiction.' She was a prolific writer, with her books translated into over a hundred languages, making her one of the best-selling authors of all time. Christie's contribution to literature was recognized with many honors, including being named a Dame Commander of the Order of the British Empire in 1971 for her contributions to literature. Her legacy continues to influence mystery writers and enthusiasts to this day. Agatha Christie passed away on January 12, 1976, leaving behind a monumental footprint on the mystery and crime literary world.
