On 12 January 1976, Agatha Christie, one of the most influential and widely read authors in literary history, died at the age of 85. With a career spanning more than five decades, Christie reshaped the crime and detective genre and became the best-selling novelist of all time, with her works translated into more than 100 languages and sales estimated at over two billion copies worldwide.
Early life and background
Agatha Mary Clarissa Miller was born on 15 September 1890 in Torquay, Devon. She was educated at home and developed a love of reading and storytelling from an early age. During the First World War, she worked as a nurse and later in a hospital dispensary, where she gained detailed knowledge of poisons — expertise that would later feature prominently in her fiction.
She married Archibald Christie in 1914, from whom she later divorced, before marrying archaeologist Max Mallowan in 1930. Her travels with Mallowan in the Middle East deeply influenced several of her novels.
Literary career and notable works
Christie published her first novel, The Mysterious Affair at Styles, in 1920, introducing the world to Belgian detective Hercule Poirot. Another iconic character, the sharp-minded amateur sleuth Miss Marple, made her debut in The Murder at the Vicarage (1930).
Among her most celebrated works are:
- Murder on the Orient Express
- And Then There Were None
- The ABC Murders
- Death on the Nile
- The Murder of Roger Ackroyd
And Then There Were None remains the best-selling crime novel of all time and is widely regarded as one of the greatest mystery novels ever written.
Theatre and stage adaptations
Christie was also a highly successful playwright. Her play The Mousetrap opened in London’s West End in 1952 and continues to run to this day, making it the longest-running play in theatrical history. She also adapted several of her novels for the stage, including Witness for the Prosecution, which became a major success both in the theatre and on screen.

Film and television adaptations
Christie’s stories have inspired countless film and television adaptations. Early classics include Witness for the Prosecution (1957), while later decades saw lavish productions such as Murder on the Orient Express and Death on the Nile. Her characters have been portrayed by some of the most prominent actors in cinema and television, ensuring her stories remain accessible to new generations.
Reception and legacy
Critics have often highlighted Christie’s ingenuity, precise plotting and mastery of misdirection. While some early critics dismissed detective fiction as light entertainment, Christie’s enduring popularity and technical brilliance have since earned her a secure place in literary history. In 1971, she was appointed Dame Commander of the Order of the British Empire (DBE) for her contribution to literature.
Lesser-known facts
- Christie was a trained singer and initially hoped for a career in music.
- In 1926, she famously disappeared for 11 days following personal turmoil, sparking a nationwide manhunt and intense media coverage.
- She wrote six romance novels under the pseudonym Mary Westmacott.
- Her archaeological work alongside her husband included cleaning artefacts using face cream — a method she claimed was both gentle and effective.
Enduring influence
Agatha Christie died peacefully at her home in Wallingford, Oxfordshire, but her influence remains undiminished. Her intricate puzzles, memorable characters and timeless settings continue to define the detective genre, making her work as compelling today as it was during her lifetime.
Nearly half a century after her death, Agatha Christie remains the undisputed “Queen of Crime” — a title earned through imagination, discipline, and an unmatched understanding of the art of mystery.
