Chapters 5-8: The Unravelling
Chapter 5: Incident of the Letter
After the Carew murder, Utterson visits Jekyll in his “cabinet” above the laboratory. Jekyll is “deathly sick”, but insists he is “done with” Hyde. He produces a letter signed by Hyde absolving him of blame. Utterson’s clerk, Mr Guest, compares the handwriting to Jekyll’s own and declares it a forgery — the letter Jekyll wrote as Hyde matches Jekyll’s hand in every feature except the slope. Stevenson plants foreshadowing: the handwriting is literally the same because the writer is.
The forged letter is Stevenson’s cleverest hint. It lets the reader register suspicion without fully understanding the truth — training us to accept the later revelation as earned, not imposed.
Chapter 6: Remarkable Incident of Doctor Lanyon
Jekyll withdraws from society, then emerges briefly as his old self. Suddenly he refuses to see Utterson again. Utterson visits Lanyon instead and finds him transformed: he “had his death-warrant written legibly upon his face.” Lanyon says he has suffered “a shock” and refuses to name its cause. He dies within weeks, leaving a sealed letter marked “not to be opened till the death or disappearance of Dr Henry Jekyll.”
Stevenson uses Lanyon as a foil to Jekyll. Both are men of science, but Jekyll calls Lanyon a “hide-bound pedant”, and Lanyon holds “the most narrow and material views”. He cannot survive the knowledge Jekyll has gained. The contrast argues that some boundaries exist for good reason.
The 1880s were a decade of rapid scientific advance and anxiety: Darwin’s ideas were reshaping biology, and new ideas in psychology were questioning whether the mind is one thing. Freud published his theories of the unconscious later, in the 1890s, so Stevenson anticipates them rather than borrows them. Stevenson’s Jekyll stands for the transgressive scientist who goes too far. Lanyon is the cautious alternative — and neither survives untouched.
The fear is not science itself, but the dissolution of the boundary between respectable professional and hidden appetites. This is why Stevenson makes the story about a doctor: the figure most trusted by Victorian society becomes the figure most dangerous.
Chapter 7: Incident at the Window
Utterson and Enfield again walk by the cursed court. Jekyll appears at the upper window, “infinite sadness” on his face. Utterson invites him down; Jekyll declines. Then “the smile was struck out of his face and succeeded by an expression of such abject terror and despair, as froze the very blood of the two gentlemen below… the window was instantly thrust down.” Stevenson compresses the whole tragedy into a single moment of horror and silence.
The chapter is short and placed centrally in the novella for good reason. Jekyll’s transformation must have started. Utterson and Enfield leave in silence, not daring to speak. Stevenson uses this silence to signal the limits of respectable language: there is nothing Victorian gentlemen can say about what they have just seen.
Chapter 8: The Last Night
Poole, Jekyll’s butler, arrives at Utterson’s in terror: “Mr Utterson, sir, I’m afraid.” For a week a stranger has been locked in the cabinet crying out for a chemical that cannot be found. Poole is convinced the voice is not Jekyll’s: “That thing was not my master.” Utterson hears a voice whining: “For God’s sake have mercy!”
Utterson and Poole break down the door with an axe. They find Hyde’s body on the floor, a phial in his hand. There is no sign of Jekyll, but two documents: Jekyll’s will (rewritten to leave everything to Utterson), and a sealed packet — the “Full Statement” that forms Chapter 10. Stevenson leaves the chapter on a cliffhanger: the reader, like Utterson, does not yet know why Jekyll’s body is Hyde’s.
Poole notices three pieces of evidence: the voice sounds wrong, the masked figure he saw himself was ‘more of a dwarf’ where his master is ‘a tall, fine build of a man’, and it cried out ‘like a rat’ and ran from him. The details rhyme with earlier descriptions of Hyde.
Jekyll’s cabinet sits above the dissecting theatre of an old surgeon. Stevenson deliberately layers the house: a respectable front, a working laboratory, an inner cabinet locked away. The architectural metaphor mirrors the Freudian-sounding model of the mind that the novella anticipates — surface, thought and hidden appetite.
Why These Chapters Matter
Chapters 5–8 are the unravelling. Stevenson switches from planting clues to accumulating them until the reader can no longer resist the conclusion. The forged letter, Lanyon’s death, Jekyll’s face at the window and Hyde’s body on the cabinet floor are arranged as a ladder down from respectable surface to exposed depth.
