Poirot is a very neat and orderly man, and he has a habit of straightening things. In solving a case, Poirot prefers not to hunt around on his knees Sherlock Holmes-style, but rather, to sit and use his "little gray cells."
Hercule Poirot is appearing in 33 novels and 51 short stories
By 1930, Agatha Christie found Poirot "insufferable", and by 1960 she felt that he was a "detestable, tiresome, ego-centric little creep". Yet the public loved him, and Christie refused to kill him off, claiming that it was her duty to produce what the public liked.
In the novels, Poirot was described as a short man, with an egg-shaped head and a big black mustache. He was extremly neat- he's friend captain Hastings said that a peck of dust on Poirot's shit would've worried him more than a bulletwound
Fictional character who appears in 12 of Agatha Christie's crime novels and in 20 short stories

Jane Marple in the first Miss Marple book, „The Murder at the Vicarage“, is different from how she appears in later books. This early version of Miss Marple is a gleeful gossip and not an especially nice woman. In later books she becomes more modern and a kinder person.
