Chapters 7–10: The Last Night and Jekyll’s Statement
Chapter 7: Incident at the Window
Utterson and Enfield pass Jekyll’s house and see him sitting at an upstairs window, looking “like some disconsolate prisoner.” They exchange pleasantries, and for a moment Jekyll seems to relax. Then, suddenly, a look of terror crosses his face, and he slams the window shut.
Utterson and Enfield walk away in silence, both deeply shaken. Stevenson never explains what happened at the window — the reader must infer that Jekyll was beginning to transform into Hyde involuntarily. This is the novella’s most chilling moment of withholding.
The window scene mirrors the opening “door” scene. Both involve Utterson and Enfield witnessing something disturbing connected to Jekyll’s house, and both end with a silent agreement not to discuss it. This structural echo reinforces the theme of Victorian repression.
Chapter 8: The Last Night
Jekyll’s butler Poole comes to Utterson in a state of panic. He believes his master has been murdered and replaced by someone hiding in the laboratory. Poole says the voice behind the locked door no longer sounds like Jekyll — it sounds like Hyde.
Utterson and Poole break down the door with an axe. Inside, they find Hyde’s body on the floor, dressed in Jekyll’s clothes, which are “far too large for him.” He has taken poison. Jekyll is nowhere to be found.
This chapter is the novella’s climax. Stevenson builds tension through Gothic elements: the screaming wind, the silent servants gathered in the hall, the sounds of pacing behind the locked door. The axe breaking down the door symbolises the violent exposure of Jekyll’s secret — the barriers he built between his public and private selves are literally smashed apart.
Finding Hyde in Jekyll’s oversized clothes provides the final physical clue. Hyde is smaller because he represents the part of Jekyll that was suppressed and undeveloped — his evil side had been “much less exercised” than his good side.
Chapter 9: Dr Lanyon’s Narrative
The narrative shifts from third-person to Lanyon’s own account, contained in his sealed letter. Lanyon describes receiving a desperate letter from Jekyll, asking him to collect chemicals from the laboratory and give them to a stranger who would arrive at midnight.
The stranger turns out to be Hyde. In front of Lanyon, Hyde drinks the potion and transforms back into Jekyll. Lanyon is so horrified that his health collapses — this is the “shock” he mentioned in Chapter 6.
The shift to Lanyon’s first-person narrative is structurally significant. It moves the reader from Utterson’s limited, rational perspective to the direct testimony of someone who witnessed the impossible. This makes the supernatural element feel more real and immediate.
Chapter 10: Henry Jekyll’s Full Statement of the Case
The final chapter is Jekyll’s own confession. He explains that he had always felt a duality within himself — a respectable public self and a hidden, pleasure-seeking private self. His experiment was designed to separate these two natures.
At first, Jekyll enjoyed the freedom of being Hyde. As Hyde, he could indulge in “undignified” pleasures without risking his reputation. But over time, Hyde grew stronger and more violent, while Jekyll grew weaker. Eventually, the transformations began happening involuntarily — Jekyll would wake up as Hyde without having taken the potion.
“Man is not truly one, but truly two” — Jekyll’s central insight, challenging the Victorian belief that identity is fixed and unified.
“I was slowly losing hold of my original and better self, and becoming slowly incorporated with my second and worse” — shows that evil, once indulged, takes over.
“It was Hyde, after all, and Hyde alone, that was guilty” — Jekyll tries to distance himself from responsibility, but the reader recognises this as self-deception.
The novella uses three different narrators: the third-person account focused on Utterson (Chapters 1–8), Lanyon’s first-person letter (Chapter 9), and Jekyll’s first-person confession (Chapter 10). Each narrator sees more of the truth than the last. This layered structure mirrors the peeling away of Jekyll’s disguise — the deeper we go, the closer we get to the horrifying reality.
