The story is told as a mystery: Utterson investigates, and the truth is only revealed in the last two chapters.
The Door and the Cheque
Utterson and his cousin Enfield pass a sinister door. Enfield describes seeing Hyde trample a young girl, then pay compensation with a cheque signed by a respectable man.
Utterson Meets Hyde
Utterson is troubled by Jekyll's will, which leaves everything to Hyde. He meets Hyde and is disgusted by him. Dr Lanyon has fallen out with Jekyll over his "unscientific" ideas.
The Carew Murder
A maid sees Hyde beat Sir Danvers Carew, a respected MP, to death with a cane. Hyde disappears.
The Letter and the Window
Jekyll shows Utterson a letter supposedly from Hyde, but Utterson's clerk notices the handwriting matches Jekyll's. Lanyon dies after a terrible shock, and Utterson and Enfield see Jekyll at a window, his face frozen in terror.
The Last Night
The butler Poole fetches Utterson. They break into Jekyll's laboratory and find Hyde dead, but no sign of Jekyll.
The Final Revelations
Lanyon's letter reveals he watched Hyde drink a potion and turn into Jekyll. Jekyll's full statement explains that he made the potion to separate the good and evil sides of himself, but lost control, began to change into Hyde without it, and ran out of the ingredient he needed.
Hyde's victim Sir Danvers Carew, a respected MP, shows that even the most respectable members of society are not safe.
Dr Henry Jekyll
A respected doctor and scientist who hides his darker desires and creates Hyde to indulge them. He loses control as Hyde grows stronger and his better self weakens.
Mr Edward Hyde
Jekyll's evil side: small, violent and repulsive. People feel instant disgust when they see him but cannot say why. His brutal acts reveal the violence hidden beneath respectable society.
Gabriel John Utterson
A rational, loyal lawyer whose step-by-step, detective-like investigation drives the story. Most of the novella follows him.
Dr Hastie Lanyon
A traditional scientist and Jekyll's old friend, who rejects Jekyll's experiments and is destroyed by the shock of what he sees.
Poole
Jekyll's loyal butler, who raises the alarm on the last night.
Richard Enfield
Utterson's cousin, who first tells the story of Hyde and the door.
The central ideas examiners expect you to explore, linked to the fears of Stevenson's Victorian readers.
Duality
Everyone has a good side and an evil side. Jekyll states it directly: "man is not truly one, but truly two".
Good and Evil
Jekyll's attempt to separate good from evil ends with evil taking over completely.
Science and Religion
Jekyll's experiments overreach, as if he is playing God. Stevenson questions what science should be allowed to do.
Reputation and Secrecy
Victorian gentlemen protect their reputations and avoid scandal, even at the cost of the truth. Utterson's loyalty to Jekyll keeps the secret hidden.
Repression and Violence
Strict Victorian morals force people to hide their desires. When they break out, as Hyde, they erupt as violence, suggesting hypocrisy in polite society.
Learn who says each line, where it comes in the story, and which theme it supports.
"like some damned Juggernaut"
Enfield, Story of the Door. Mechanical, destructive imagery for Hyde trampling the girl: he is unstoppable and inhuman.
"I shall be Mr. Seek"
Utterson, Search for Mr Hyde: "If he be Mr. Hyde, I shall be Mr. Seek." His determination to uncover the mystery, and the novella's detective structure.
"Satan's signature upon a face"
Utterson, Search for Mr Hyde. Religious imagery presents Hyde as devilish. In the same chapter he is described as "pale and dwarfish".
"with ape-like fury"
The narrator, The Carew Murder Case. Animal imagery presents Hyde as primitive and less than human, echoing Victorian fears raised by Darwin.
"man is not truly one, but truly two"
Jekyll, Full Statement. The clearest statement of the novella's central idea: the duality of human nature.
"losing hold of my original and better self"
Jekyll, Full Statement: "I was slowly losing hold of my original and better self". Evil gradually takes over.
The fears of the 1880s that Stevenson's readers would have recognised.
Victorian Respectability
Reputation mattered enormously, and gentlemen were expected to hide anything shameful. Public respectability could cover private vice, as in Jekyll's double life.
Darwin and Evolution
On the Origin of Species (1859) raised fears that humans were close to animals and could slide backwards into savagery, which Hyde seems to embody.
Victorian London
Wealthy streets lay right beside poverty and crime, much like Jekyll's respectable house backing onto Hyde's sinister door.
Deacon Brodie
An Edinburgh craftsman who was respectable by day and a burglar by night, a story Stevenson knew well.
Gothic Fiction
The novella uses Gothic features such as mystery, darkness, fear and the hint of the supernatural.
How Stevenson builds suspense and makes the duality theme visible.
Multiple Narrators
The story is pieced together from Utterson's view, Lanyon's letter and Jekyll's statement. The letters and documents give it the feel of a case being solved.
Delayed Revelation
The truth is withheld until the last two chapters, so readers investigate alongside Utterson and the suspense keeps building.
Gothic Setting
Fog, darkness and empty night-time streets create fear and hide what is really happening.
Descriptions of Hyde
No one can say exactly what is wrong with him, so readers' imaginations make him more frightening than any description could.
Doors and Houses
Jekyll's grand front door and Hyde's shabby back door belong to the same building, like the two sides of one man.
The main themes are duality, good and evil, science and religion, reputation and secrecy, and repression and violence. They all come back to Jekyll's idea that "man is not truly one, but truly two".
Hyde represents the evil, violent side of human nature that respectable Victorians tried to hide. His animal-like descriptions also reflect fears, raised by Darwin's ideas, that humans could slide back into savagery.
Using Utterson's investigation, Lanyon's letter and Jekyll's statement lets Stevenson hold back the truth until the end. Readers piece the mystery together like a detective, which builds suspense.
Utterson and Poole break into the laboratory and find Hyde dead. Lanyon's letter and Jekyll's full statement then reveal that Jekyll and Hyde were the same man, and that Jekyll lost control of the transformations.
