Strange Case of Dr. Jekyll and Mr. Hyde: Book Report and Analysis

Everyone knows the phrase “Jekyll and Hyde.” It has been a shorthand for split personalities for over a century. But the actual book — Robert Louis Stevenson’s Strange Case of Dr. Jekyll and Mr. Hyde — is stranger and sadder than the phrase suggests. It is a horror story, yes, but it is also a story about loneliness, addiction, and what happens when a good man decides he wants to be bad without paying for it. This is a full book report.

About the author

Robert Louis Stevenson was a Scottish writer born in Edinburgh in 1850. He came from a family of lighthouse engineers — his father and grandfather built some of Scotland’s most famous lighthouses — and he was expected to follow them into the trade. Instead, he studied law and then abandoned it for writing, to his family’s dismay. He wrote adventure stories (Treasure Island, 1883), historical fiction (Kidnapped, 1886), poetry (A Child’s Garden of Verses, 1885), and essays. He was chronically ill with tuberculosis for most of his life and spent his final years in Samoa, in the South Pacific, where he died in 1894 at the age of 44.

The story of how Jekyll and Hyde was written is famous. Stevenson, who was often bedridden, dreamed the key scene — the transformation — and woke up and wrote the first draft in three days. His wife Fanny read it and told him it was a good story but not a great one; it was too much of a “crawler,” she said, too sensational. Stevenson, furious, threw the manuscript in the fire and rewrote it from scratch in three more days. The version we have is the rewrite. It was published in January 1886 and was an immediate success, selling out its first printing within months.

The setup

The novella is told mostly through the eyes of Mr. Utterson, a London lawyer and a friend of Dr. Henry Jekyll. Utterson is a dry, respectable man — the kind who keeps his own counsel and minds his own business. The story opens with Utterson’s friend Mr. Enfield telling him about a strange incident: a small, deformed man named Edward Hyde trampled a little girl in the street at night, and when Enfield confronted him, Hyde paid off the family with a check signed by a respectable man — Dr. Jekyll. Enfield is disturbed by Hyde in a way he cannot explain. Just looking at the man made his blood run cold.

Utterson, who is Jekyll’s lawyer, is troubled. He has heard Hyde’s name before: Jekyll recently changed his will to leave everything to Hyde. Utterson begins to investigate, and what he finds pulls him into a nightmare.

The characters

Dr. Henry Jekyll is a respected physician and scientist in his fifties, known for his charity work and his good name. He is a man who has spent his whole life being good — and, as we learn, resenting it. He is the novel’s tragic figure: a man who wants to separate the two halves of himself and ends up destroying both.

Mr. Edward Hyde is Jekyll’s creation — a separate body for the evil side of Jekyll’s nature. He is small, deformed, and somehow wrong in a way no one can articulate. People who meet him feel a visceral disgust. He is pure appetite: cruel, violent, and utterly without conscience.

Mr. Utterson is the narrator of most of the story. He is the reader’s stand-in — a decent, cautious man who slowly realizes that his friend is in terrible trouble. His loyalty to Jekyll is the emotional engine of the book.

Dr. Lanyon is Jekyll’s oldest friend and fellow physician. He and Jekyll quarreled years before the story begins, over what Lanyon called Jekyll’s “scientific heresies.” Lanyon is the one who witnesses the truth firsthand, and it destroys him.

Mr. Poole is Jekyll’s butler, and he gets one of the best scenes in the book — the servant who knows something is terribly wrong in his master’s house.

The plot, without spoilers

Utterson’s investigation leads him to Hyde’s door, but Hyde is gone by the time he gets there. Jekyll, when pressed, tells Utterson not to worry — he can be rid of Hyde whenever he likes. But he cannot, and the story moves toward its terrible climax: the murder of a respected Member of Parliament, Sir Danvers Carew, by Hyde, witnessed by a maid. The murder weapon is a broken cane that Utterson recognizes — a gift he gave to Jekyll.

From there the story tightens like a noose. Hyde vanishes. Jekyll seems to recover, returning to his old self, hosting dinners, doing good works. But then Jekyll begins to fail — locking himself in his laboratory, refusing to see anyone, writing strange letters. His handwriting changes. His servants hear him weeping. And at the end, Utterson and Poole break down the laboratory door to find out what is really going on.

The final section of the book is Jekyll’s own written confession, which explains everything — and it is one of the great endings in English literature.

Themes

The duality of human nature. The obvious theme: every person contains good and evil. What makes the book radical for its time is that Stevenson refuses to say the good half wins. Jekyll’s tragedy is that he cannot integrate his two halves — he can only suppress one and unleash the other, and both choices destroy him.

Repression and respectability. Victorian London was a society obsessed with appearances. Jekyll is the ultimate respectable man, and his respectability is exactly what suffocates him. The book is a critique of a culture that demanded people be one thing in public and another in private — and then pretended the private thing did not exist.

Addiction. Read it today and it is impossible not to see addiction in Jekyll’s story: the first transformation is thrilling, the drug becomes necessary, the doses stop working, and the user loses control of his own body. Stevenson wrote the book decades before modern addiction science, but he captured the experience perfectly.

Science without ethics. Jekyll is a scientist who does something forbidden and refuses to face the consequences. Lanyon, the moral traditionalist, is horrified — and Stevenson makes clear that Lanyon is right to be.

Writing style

The book is a novella — about 90 pages — and it is tightly built. Stevenson writes in a formal Victorian register, with long sentences and careful diction, but he knows exactly when to break it. The descriptions of Hyde are the best part: Stevenson never tells you what Hyde looks like. He tells you how people feel when they see him — the nausea, the cold sweat, the sense of something profoundly wrong. It is a masterclass in horror through suggestion.

What works

  • The atmosphere. London at night, fog, locked doors, a house with something behind it — Stevenson builds dread better than most modern horror writers.
  • Hyde himself. He is terrifying precisely because he is never fully described.
  • The structure. The mystery unfolds through multiple viewpoints, and the confession at the end lands like a hammer.
  • It is short. You can read it in an evening, and it will stay with you for years.

What does not work

  • The Victorian prose takes some getting used to. If you are not a patient reader, the first few pages can feel slow.
  • The story is so famous that the twist may not surprise you — though the way it is delivered still lands.
  • Some modern readers find the moralizing heavy-handed. It is a product of its time.

Who should read it

Read it if you like classic horror, gothic fiction, or stories about the dark side of human nature. Read it if you have only ever known the phrase and want the real thing. It is also a great book for students — it is short, rich, and endlessly analyzable.

Verdict

5 out of 5. One of the most influential books ever written in English, and it earns every bit of its reputation. It is a horror story, a psychological study, and a social critique all at once, and it does all three in under a hundred pages. If you have never read it, you owe yourself the evening.
