Atmosphere of the Novel

Overall Atmosphere: Dr Jekyll and Mr Hyde exhibits a haunting, ominous, and dark atmosphere throughout the narrative. The oppressive atmosphere reflects the internal conflicts of the characters, especially Dr Jekyll and Mr Hyde.
Depiction of London: The description of London contributes greatly to the oppressive atmosphere. The city is depicted as foggy, dreary, and labyrinth-like - reflecting the baffling mystery that engulfs the characters and the narrative.
“A great chocolate-coloured pall lowered over heaven…” (Chapter 4)
“…for London was startled by a great crime…” (Chapter 4)
Jekyll’s House and Laboratory: Jekyll’s home and laboratory contribute to the eerie atmosphere. The house’s dichotomy between the luxurious front (Jekyll’s side) and dilapidated back (Hyde’s side) reflect on the characters’ dual nature.
“…the pleasantest room in London… but now there were shrill cries of laughter…” (Chapter 5)
“Round the corner from the by-street, there was a square of ancient, handsome houses, now for the most part decayed from their high estate…One house, however, second from the corner, was still occupied entire; and at the door of this…there lay a great many odd volumes of Victoriana…” (Chapter 1)
Importance of Darkness: Darkness is extensively used as a symbol to depict the prevalent evil, fear, and secrecy in the novel. Many pertinent events occur at night, enhancing the gloomy and foreboding atmosphere.
“…a night of little ease to his toiling mind…” (Chapter 8)
Establishing Fear: Stevenson manages to create an atmosphere of fear and discomfort using detailed description and powerful imagery.
“…an expression of such abject terror and despair, as froze the very blood of the two gentlemen below…” (Chapter 2)

Remember, the atmosphere of a novel is vital in setting the tone and mood. It can provide insight into characters’ emotions or the novel’s thematic elements.
