Agatha Christie (1890-1976), born in Torquay, Devon, England, became the world's best-selling novelist through her mastery of the detective mystery genre and ingenious plot construction.

Major Works

• The Murder of Roger Ackroyd (1926) - featuring detective Hercule Poirot with a revolutionary narrative twist
• Murder on the Orient Express (1934) - set aboard a luxury train with multiple suspects and motives
• And Then There Were None (1939) - ten strangers isolated on an island facing systematic elimination
• The ABC Murders (1936) - a serial killer case that challenges Poirot's deductive abilities

Recognition and Achievement

Christie was appointed a Dame Grand Cross of the Order of the British Empire in 1971, recognizing her literary contributions. Her play The Mousetrap (1952) holds the record for the longest-running theatrical production in history.

Writing Technique

Christie pioneered the locked-room mystery and the unreliable narrator device, where crucial information about the culprit's identity is deliberately withheld from readers until the final revelation. She meticulously plotted her novels years in advance, sometimes writing multiple books simultaneously and storing completed manuscripts for future publication. Her works have sold over 2 billion copies worldwide.
