The Mysterious Affair at Styles is a detective novel by British writer Agatha Christie. It was written in the middle of the First World War, in 1916, and first published by John Lane in the United States in October 1920 and in the United Kingdom by The Bodley Head (John Lane's UK company) on 21 January 1921. Styles was Christie's first published novel. It introduced Hercule Poirot, Inspector (later, Chief Inspector) Japp, and Arthur Hastings. Poirot, a Belgian refugee of the Great War, is settling in England near the home of Emily Inglethorp, who helped him to his new life. His friend Hastings arrives as a guest at her home. When the woman is killed, Poirot uses his detective skills to solve the mystery.
Agatha Mary Clarissa, Lady Mallowan, DBE (15 September 1890 – 12 January 1976), commonly known as Agatha Christie, was an English crime fiction writer. She also wrote romance novels under the name Mary Westmacott, but is best remembered for her 80 detective novels and her successful West End theatre plays. Her works, particularly featuring detectives Hercule Poirot or Miss Jane Marple, have given her the title the 'Queen of Crime' and made her one of the most important and innovative writers in the development of the genre.
