Story of the Door Question

Are you referring to the beginning of the story? At the book's opening, two men, Mr. Utterson and his cousin Mr. Richard Enfield, are leisurely walking through London. Initially silent, the men pass a mysterious basement cellar door, and Mr. Enfield launches into a story about a strange occurrence related to the door. Late one night, while on his way home, Enfield chanced upon a deformed, short man who trampled a girl in the street on her way to fetch a doctor. The girl's family and Mr. Enfield catch the mysterious man and instead of getting the police, decide to force him to give the girl's family money.
