The author (Stevenson) attempt to create a Sinister setting.Throughout the passage of Dr.Jekyll and Mr.Hyde.In Chapter 4 the theme of secrecy and repression is interestingly contrasted with the public nature of Hyde’s evil crimes.The murder both involves Utterson again and invites scandal as if the perpetrator is secretly wanting to be exposed kinda weird.The author doesn’t create random victims for Hyde. Just like the little girl in the first account, this old gentleman, with the symbolic heavenly light around him and his divine appearance, is a figure of innocence and creates a deeper contrast with Hyde’s wickedness.Mr.Hyde lift his heavy walking stick and beat the old guy to a bloody pulp, The maid described it as horrible as she saw his bones cracked and him being tortured and her not being able to do anything because she fainted.When the police arrived at the scene they couldn’t find the body, and they were surprised none of the old guy-jewelry and money were not taken.They found an envelope concerned of the killer identity, the envelope was then addressing to Mr.Utterson.Then they call Mr.Utterson to help them identify the dead body.When Utterson sees the weapons, he is able to recognize it as a belonging to Dr.Jekyll and he told the police where the killer is Hyde.Stevenson is building up a world of symbols that denote the appearance of Hyde and the approach of evil.Muggy weather and weird lights is a sign of the unclear masked nature of the events, but they are also constantly changing, creating a new landscape with each glance, making the atmosphere unpredictable. The description of Hyde’s looks, with the phrases twisted-looking, ugly and deformed recurring in each account, follows him as a symbol to remind the reader.The weather represents the secrecy and suspicion that is haunting the streets. The way Hyde’s state is described from the other homes gives a fated, threatening sense to Utterson’s expedition.Giving Mr.Hyde the ability to inspire hatred in others, it is unclear if the old lady is naturally twisted or if her exposure to Mr.Hyde has made her the way she is.This old lady is an example of what Jekyll will later describe as his theory of the condition of man, that everyone has both good and evil in them.One problem the police faced is that the cops could not identify Mr.Hyde. throughout the chapter, we watch the investigator look for Hyde.Characters continue to change throughout the novel.
