From Wikipaedia:
Christie’s first published book, The Mysterious Affair at Styles, was released in 1920 and introduced the detective Hercule Poirot, who appeared in 33 of her novels and more than 50 short stories.
Over the years, Christie grew tired of Poirot, much as Doyle did with Sherlock Holmes.[3]: 230 By the end of the 1930s, Christie wrote in her diary that she was finding Poirot “insufferable”, and by the 1960s she felt he was “an egocentric creep”.[107] Thompson believes Christie’s occasional antipathy to her creation is overstated, and points out that “in later life she sought to protect him against misrepresentation as powerfully as if he were her own flesh and blood.”[13]: 282 Unlike Doyle, she resisted the temptation to kill her detective off while he was still popular.[3]: 222 She married off Poirot’s “Watson“, Captain Arthur Hastings, in an attempt to trim her cast commitments.[11]: 268
