Strange Case of Dr Jekyll and Mr Hyde
1886 · 19th Century · Novella · English
Abstract
Background. Composed while its author was an invalid on the south coast of England, the tale grew, by Stevenson's own account, from a dream. It was issued as a cheap shilling book and quickly became a bestseller on both sides of the Atlantic.
Plot. A lawyer grows alarmed when a client's will favours a violent stranger who tramples a child and later kills an elderly politician. Clues accumulate: matching handwriting, a doctor who dies of fright, a face at a window frozen in horror. When servants force the laboratory door, they find only the stranger's corpse. Letters left behind reveal that the physician himself had brewed a potion that let his worse nature walk the city in another body, until the change could no longer be reversed.
Structure. Eight chapters of detection seen from outside give way to two documents, so the reader learns the explanation only after the deaths.
Themes. The duality of human nature, the gap between reputation and conduct, the seductions of unrestrained science, and the slow enslavement of the will. Jekyll insists he was never a mere pretender, since both his selves were in dead earnest, and Stevenson leaves the reader to weigh that plea.
Significance. The paired names entered common speech, and the story has been adapted for stage and screen many times.

Summary
Mr. Utterson, a reserved and loyal London lawyer, takes his Sunday walk with his kinsman Richard Enfield, who points out a shabby door in a by-street and tells how, at three one winter morning, he saw a small man trample a little girl and walk on. Caught and threatened, the man paid close to a hundred pounds in compensation with a cheque signed by a respected gentleman. The man's name was Hyde. Utterson is disturbed, for he holds the will of his old friend Dr. Henry Jekyll, which leaves everything to Edward Hyde and provides for Jekyll's disappearance. Dr. Hastie Lanyon, who quarrelled with Jekyll years ago over his unscientific balderdash, knows nothing of Hyde. Utterson watches the door until he meets Hyde, a pale, dwarfish man who gives everyone who sees him a sense of deformity no one can name. Jekyll, pressed at a dinner, assures Utterson that he can be rid of Hyde whenever he chooses. Nearly a year later a maid sees Hyde club to death the elderly Sir Danvers Carew, a member of Parliament, with a heavy cane. Hyde vanishes from his rooms in Soho. Jekyll produces a letter from Hyde promising never to return, but the head clerk, Mr. Guest, notices that its handwriting matches Jekyll's own, sloped differently. For two months Jekyll is sociable and devout; then he shuts himself away, and Lanyon, after some shock he will not describe, sickens and dies, leaving Utterson a sealed paper not to be opened before Jekyll's death or disappearance. One evening Jekyll's butler Poole comes to Utterson in fear: the voice in the doctor's locked cabinet is not his master's, and endless notes are sent to the chemists for a pure supply of some salt. Utterson and Poole break down the door with an axe and find Hyde, dressed in clothes far too large, dead by his own hand, with no trace of Jekyll. Two documents complete the story. Lanyon's narrative tells how, at Jekyll's urgent request, he took a drawer of powders and a phial from the cabinet and received a stranger at midnight, who mixed the draught and changed before his eyes into Henry Jekyll. Jekyll's full statement explains that, aware all his life of a double nature, he discovered a drug that gave his darker self a body of its own, younger, smaller and free of conscience. Pleasure turned to cruelty; the changes began to happen unbidden in sleep and in Regent's Park, larger doses were needed, and the murder of Carew ended any hope of control. When his last supply of the salt ran out and a new one failed, he understood that the first had been impure. He writes his confession in his last hour as Jekyll. Stevenson wrote the novella at Bournemouth in 1885; Longmans, Green published it in London on 5 January 1886, and it sold close to forty thousand copies within six months.
Virtues in this work
- Friendship: Utterson keeps faith with Jekyll for years, tracking Hyde and finally breaking down the cabinet door to help him.
- Temperance: Jekyll's two months of abstinence collapse into a frenzy that ends in the Carew murder, showing what is lost when appetite is indulged rather than mastered.
- Humility: Jekyll's confession shows a man who chose to hide his faults rather than admit them, and whose pride in his reputation helped create Hyde.
- Prudence: Utterson honours Lanyon's instruction not to open the sealed envelope before Jekyll's death or disappearance, even though curiosity tempts him.

Lessons
Respectability is not virtue
Jekyll is honoured, charitable and outwardly devout, yet he has long hidden a desire for pleasures he thinks beneath his dignity. Rather than repent, he invents a way to sin without being seen. Stevenson shows that a reputation guarded for its own sake can become the very cloak under which vice grows.
- What does Jekyll say in his statement about why he concealed his pleasures in the first place?
- Why does Hyde need the respectable Jekyll as much as Jekyll needs Hyde?
- Is concealing a fault ever the first step toward a worse one?
The illusion of control
Jekyll tells Utterson that he can be rid of Hyde the moment he chooses, but each indulgence makes the change easier and the return harder, until Hyde appears in his sleep and in a public park. Habit, Stevenson suggests, slowly reshapes the self. The novella reads as a study of how repeated choices become a master.
- When does Jekyll first wake up as Hyde without taking the drug, and why does this frighten him?
- What happens when Jekyll tries to give Hyde up for two months?
- How is Jekyll's confidence in his own control like the confidence of anyone caught in a bad habit?
The divided self and the united person
Jekyll concludes that man is not truly one, but truly two, and he hopes to separate the two natures so each can go its way. The experiment frees only the evil side; the good side gains nothing. The story implies that the moral struggle cannot be escaped by chemistry, only fought within one person.
- Why does the drug produce a purely evil Hyde but not a purely good Jekyll?
- What does Jekyll mean by the perennial war among his members?
- Could anything have saved Jekyll after the murder of Carew?
Friendship and silence
Utterson, Lanyon and Poole are loyal men who sense something is wrong yet hesitate to pry, out of courtesy and fear of scandal. Their reticence protects Jekyll's name but leaves him alone with his secret. Stevenson's gentlemen show both the dignity and the cost of not asking.
- Why does Utterson refuse to open Lanyon's envelope early?
- Should Utterson have acted sooner, and what would that have looked like?
Context
The novella is set in a foggy late-Victorian London of professional men, lawyers and doctors, where reputation was everything and a respectable West End could lie a few streets from the poverty of Soho. It appeared at a time of keen interest in evolution and degeneration, in the new physiological psychology, and in published cases of so-called double consciousness, in which a patient seemed to alternate between two personalities. Stevenson does not cite such cases, and readers should not assume he drew on any particular one.
Composition
Stevenson, often bedridden with lung haemorrhages, wrote the story in 1885 at Skerryvore, his house in Bournemouth. In his essay A Chapter on Dreams (1888) he says that the central scene of the transformation came to him in a dream. A widely repeated family account holds that he burned a first draft after his wife Fanny's criticism and rewrote it in a few days. Longmans, Green published it on 5 January 1886 as a shilling paperback, with a New York edition from Scribner's the same month.
Reception
The book was an immediate success, selling close to forty thousand copies in Britain within six months; it was read by people who did not usually read fiction and was cited in sermons and religious papers. Thomas Russell Sullivan's stage adaptation, starring Richard Mansfield, opened in Boston in 1887 and played in London in 1888. The names Jekyll and Hyde passed into ordinary English for a person with a hidden second character.
Comparisons
- frankenstein
Both stories turn on a scientist whose secret experiment produces a being he cannot control, but Frankenstein's creature is a separate person while Hyde is Jekyll himself.
- dracula
A decade later Stoker also used a mosaic of letters, diaries and narratives by professional men to uncover a monstrous figure hidden in respectable London.
- confessions
Augustine's account in Book VIII of two wills at war within him, one old and carnal and one new and spiritual, is the classic Christian treatment of the inner division Jekyll tries to solve with a drug.
- the-screwtape-letters
Lewis, like Stevenson, shows how small indulgences and self-deceptions gradually capture a soul, though Lewis writes from the tempter's side.
- studies-on-hysteria
Breuer and Freud, writing a decade later, built their account of hysteria on the splitting of consciousness, a clinical counterpart to the double life Stevenson imagined.
- treasure-island
Stevenson's earlier adventure also centres on a man of two faces: Long John Silver, whose charm and treachery are as inseparable as Jekyll and Hyde.

Seminar Questions
- Comprehension What does Enfield see Hyde do in the first chapter, and how does Hyde pay for it?
- Comprehension Why is Utterson so troubled by the terms of Jekyll's will?
- Comprehension What does Lanyon witness that destroys his health?
- Interpretation Why does Stevenson tell most of the story through Utterson, a man who never learns the truth until he reads the documents?
- Interpretation Hyde is smaller and younger than Jekyll. What does Jekyll suggest this means about the evil side of his nature?
- Interpretation Jekyll calls himself the chief of sinners and the chief of sufferers. Is his statement at the end a true confession, or still a defence of himself?
- Big Question Is the evil in a person something separate that can be cut away, or part of one self that must be fought and forgiven?
- Big Question What does the story suggest about keeping a good reputation while hiding a secret life?
Faith Connections
- Romans 7:15-25 (Scripture)
Paul describes another law in his members warring against the law of his mind; Jekyll speaks of the perennial war among his members. Paul cries out for deliverance and thanks God through Christ, while Jekyll seeks deliverance through a drug.
- 1 Timothy 1:15 (Scripture)
Paul calls himself the chief of sinners in a passage about Christ coming to save sinners; Jekyll borrows the phrase in his letter but adds that he is chief of sufferers, without turning to the mercy Paul received.
- Genesis 4:9 (Scripture)
Cain's question, Am I my brother's keeper?, lies behind Utterson's joke about Cain's heresy; the story then tests how far a friend should go to keep his brother.
- Augustine, Confessions VIII (Church Fathers)
Augustine describes two wills, one old and one new, struggling within him until grace unites him; Jekyll's attempt to house his two wills in two bodies is the opposite remedy, and it fails.
Logic and Rhetoric
Central argument: Every person is a mixture of good and evil. If a man tries to separate the two so that he may indulge evil without guilt, the evil, freed from restraint, grows stronger while the good gains nothing. Therefore the attempt to escape moral struggle, by chemistry or concealment, ends in the destruction of the whole self.
Rhetorical device: pun. In Search for Mr. Hyde Utterson plays on the name of the man he is hunting: if he be Mr. Hyde, he will be Mr. Seek, turning the whole mystery into a children's game of hide and seek.
Debate: Resolved: that Henry Jekyll is fully responsible for the crimes committed by Edward Hyde.
Memory Work
man is not truly one, but truly two.
I was slowly losing hold of my original and better self, and becoming slowly incorporated with my second and worse.
Writing Prompts
Essay: Jekyll says the drug did not create Hyde but only shook the doors of his prison. Using his full statement, argue whether Jekyll was a good man destroyed by a drug or a divided man exposed by it.
Comparison with Frankenstein: Compare Victor Frankenstein and Henry Jekyll as scientists who make something they cannot control. Which one bears more responsibility for the harm that follows, and why?
Medical Lens
The novella is built around physicians and a drug. Jekyll is a doctor of medicine and law and a fellow of the Royal Society, Lanyon a fashionable practitioner in Cavendish Square, and their old quarrel sets conventional medicine against Jekyll's mystic and transcendental science. The transformation depends on a white crystalline salt from a wholesale chemist mixed with a blood-red tincture; it brings nausea, grinding in the bones and deadly horror, and later a single dose no longer suffices and the dose must be doubled. Readers since publication have read the story as an image of addiction: Jekyll's promise that he can stop when he chooses, his two months of abstinence followed by a fierce relapse, the spontaneous changes, and the frantic notes to the chemists for a purer supply. That reading is interpretive; Stevenson never names a real drug, and claims that he wrote under the influence of cocaine are not supported by evidence. The book also appeared amid medical interest in double or alternating personality and in degeneration, and Hyde's smaller, apelike body echoes contemporary fears of moral regression; here too any link is a reading, not a documented source. Lanyon's sleeplessness, terror and death within weeks of what he saw are a period picture of a man killed by shock. Hyde's death by poison, recognised by the smell of kernels in the cabinet, is a suicide, and the whole story raises the question of a physician who experiments on himself without restraint.

Verification notes
Plot details and chapter titles follow the attached Project Gutenberg text (#43), which prints the sixth chapter as Incident of Dr. Lanyon in its contents; the first edition heading reads Remarkable Incident of Dr. Lanyon. The publication date of 5 January 1886 by Longmans, Green and the sales of close to forty thousand copies within six months were checked by web search (e.g. theorkneynews.scot, 5 January 2025, and rare-book dealer descriptions). The dream origin rests on Stevenson's own essay; the burned first draft is a family account, reported as such. The addiction and double-personality readings in medicalLens are interpretive. All quotes were found in the attached text.
- Confirm the story of the burned first draft, which rests on Lloyd Osbourne's and Fanny Stevenson's later recollections.
- Confirm the dates of the Sullivan-Mansfield adaptation (Boston, May 1887; London, August 1888) before publication.
- Confirm whether the sixth chapter should be cited as Remarkable Incident of Dr. Lanyon (first edition) or Incident of Dr. Lanyon (Gutenberg contents).
