Strange Case of Dr Jekyll and Mr Hyde Summary: A Tale of Duality
In *The Strange Case of Dr. Jekyll and Mr. Hyde*, Robert Louis Stevenson builds a mystery about reputation, secrecy, and the hidden parts of human nature.

TL;DR: The Hidden Self
Dr. Henry Jekyll creates a chemical formula to separate his respectable public identity from his forbidden desires. The result is Edward Hyde, a smaller, violent, and entirely evil version of himself.
At first, Jekyll controls the changes. Over time, Hyde begins to take over without warning.
The story follows lawyer Gabriel John Utterson as he investigates Hyde’s connection to Jekyll.
The truth is revealed only after Hyde murders Sir Danvers Carew and Jekyll locks himself away.
Final letters from Dr. Lanyon and Jekyll explain the full transformation, ending with Jekyll’s confession and death as Hyde.

Mr. Utterson and his kinsman Mr. Enfield pass a neglected building with a blistered door.

Utterson realizes he knows the man who signed the check.

Utterson reads Dr. Jekyll’s will, which leaves everything to Hyde. He visits Dr. Lanyon, who has fallen out with Jekyll over scientific ideas. Utterson watches the door until he meets Hyde, who gives him a Soho address. Poole, Jekyll’s butler, confirms that Hyde has access to the laboratory.
Chapter 3: Dr. Jekyll Was Quite at Ease
Jekyll hosts a dinner and speaks with Utterson alone. He refuses to discuss Hyde, calls Lanyon a pedant, and insists he can be rid of Hyde whenever he chooses. Jekyll asks Utterson to promise to help Hyde if he disappears. Utterson gives his word.
Chapter 4: The Carew Murder Case
A maid sees Hyde beat Sir Danvers Carew to death with a cane. Utterson identifies the cane as one he gave to Jekyll. He leads the police to Hyde’s rooms in Soho, where they find the other half of the cane and burned checkbook remains. Hyde vanishes completely.
Chapter 5: Incident of the Letter
Jekyll is sick and swears he is done with Hyde. He gives Utterson a letter from Hyde. Poole says no messenger delivered it. Mr. Guest, Utterson’s clerk, notices that Hyde’s handwriting matches Jekyll’s except for the slant. Utterson believes Jekyll forged the letter.
Chapter 6: Incident of Dr. Lanyon
Hyde stays missing and Jekyll returns to public life for a while. Then Jekyll suddenly shuts himself away. Lanyon is dying from a mental shock and refuses to hear Jekyll’s name. Lanyon dies and leaves Utterson a sealed packet to be opened only after Jekyll’s death or disappearance.
Chapter 7: Incident at the Window
Utterson and Enfield see Jekyll at a laboratory window looking like a prisoner. During their brief talk, Jekyll’s face twists with terror and despair. He slams the window shut. The two men leave in silence.
Chapter 8: The Last Night
Poole comes to Utterson in fear. For eight days, a locked creature in the cabinet has been demanding a pure drug and rejecting every sample. Utterson and Poole break down the door. They find Hyde dying in Jekyll’s clothes. Jekyll is gone. They find a new will, a note, and Jekyll’s confession.
Chapter 9: Dr. Lanyon’s Narrative
Lanyon’s letter describes retrieving chemicals from Jekyll’s laboratory. A midnight visitor mixed the powders and drank the liquid. Lanyon watched the man change into Henry Jekyll. The shock destroyed Lanyon’s health and revealed that Hyde was the murderer.
Chapter 10: Henry Jekyll’s Full Statement of the Case
Jekyll’s confession explains his lifelong split between public respectability and hidden desires. The drug turned him into Hyde, a form of pure evil.
Over time, Hyde grew stronger and appeared without warning. The original chemicals ran low, and new supplies proved useless. Facing permanent possession by Hyde, Jekyll wrote his confession and ended his life.

The Strange Case of Dr. Jekyll and Mr. Hyde Summary
Spoiler warning: The following summary includes the complete ending.
The story starts with Mr. Utterson and Mr. Enfield on a Sunday walk. Enfield tells of seeing Edward Hyde trample a girl and pay for the damage with a check signed by Dr. Jekyll.
Utterson already holds Jekyll’s will, which gives everything to Hyde. He tries to meet Hyde and is disturbed by his appearance. Hyde gives him a Soho address and hints that he knows about the will.
Utterson fears blackmail. Jekyll tells him to drop the matter and insists he can end his connection to Hyde at any moment.
Nearly a year later, Hyde murders Sir Danvers Carew with a cane that belongs to Jekyll. Hyde disappears. Jekyll claims he is free of him.
Utterson’s clerk finds that Hyde’s letter and Jekyll’s handwriting are almost identical. Robert Louis Stevenson uses this detail to push the lawyer toward a darker suspicion.
Jekyll isolates himself. Lanyon falls ill and dies after witnessing something he refuses to describe. He leaves a sealed narrative for Utterson.
One night, Poole reports that a strange voice has been locked in the laboratory cabinet demanding a specific drug. Utterson and Poole break in. They find Hyde dying in clothes that belong to Jekyll.
Two documents explain the truth. Lanyon saw Hyde drink a potion and transform into Jekyll. Jekyll’s confession reveals that he used chemistry to separate his good and evil sides.
Hyde was that evil side. At first, Jekyll controlled the changes. Later, the transformations happened on their own. The original drug supply failed, and no new batch worked.
Jekyll knew Hyde would soon take over permanently. He wrote his confession and prepared for the end. The book closes with the life of Henry Jekyll coming to an end.
