Hercule Poirot was real.
One of the interesting facts about Agatha Christie is that the character Hercule Poirot she wrote is real. Hercule Poirot was introduced in Christie's first book, The Mysterious Affair at Styles, which was published in 1920. Christie, a Belgian, took inspiration from a Belgian man for his book dapper hero early 1900s saw off the bus. With his strange facial hair and peculiar attitude, he was thought to have an off-putting appearance. Does he have a neat mustache and manly fashion? He served as the model for a character that appeared in more than 40 best-selling mystery novels and fit in well in Torquay, England.
Like Conan Doyle did with Sherlock Holmes, Christie has grown sick of Poirot with time. In her diary, Christie noted that she thought Poirot was "irreparable" in the late 1930s and that he was "a selfish man" in the 1960s. By pointing out that "in later life, she strove to defend him against distortion in a way strong as if he were her flesh and blood," Thompson, Christie's biographer contends that Christie's frequent hostility to her work is overdone. She resisted the need to murder her detective while he was still well-known, in contrast to Conan Doyle.
