The Murders in the Rue Morgue
An eccentric Parisian reasons out a brutal locked-room double murder that baffles the police.
When a mother and daughter are killed in a sealed fourth-floor apartment, the witnesses cannot agree on the strange voice they heard, and the police arrest an innocent man. C. Auguste Dupin, applying pure analytic reasoning, deduces that the unidentifiable voice and superhuman violence point not to a human killer but to an escaped Ourang-Outang. His method launches the modern detective story.
What happens
After an essay on the analytic mind, the narrator describes meeting the brilliant, reclusive C. Auguste Dupin in Paris and sharing lodgings with him. The newspapers report the shocking murders of Madame L’Espanaye and her daughter in a locked room on the Rue Morgue, the daughter forced up a chimney and the mother nearly decapitated. Witnesses heard two voices, one gruff Frenchman and one shrill speaker each listener assigns to a different foreign language none of them knows. Police are baffled by the sealed room and arrest Le Bon, a bank clerk who had delivered money. Dupin visits the scene, examines the windows, and reasons that the killer escaped through a window whose spring and hidden nail concealed a working exit. From the inhuman strength, the tuft of non-human hair, and the impossible voice, he concludes the murderer is an Ourang-Outang. He places a newspaper advertisement that draws out the animal’s owner, a sailor, who confirms that his escaped ape committed the killings, and Le Bon is freed.

- Setup On analysis and Dupin
The narrator muses on the analytic faculty, then introduces the impoverished, night-loving genius C. Auguste Dupin and their shared Paris lodgings.
- Rising The murders reported
Newspapers describe the savage deaths of Madame L’Espanaye and her daughter in a room locked from inside on the Rue Morgue.
- Rising The conflicting voices
Witnesses agree on a gruff French voice but each attributes the shrill second voice to a different language none of them speaks.
- Turn Dupin investigates
Granted access to the scene, Dupin studies the windows, the nails, and the greasy lightning-rod route the police overlooked.
- Climax The deduction
From strength, agility, the strange voice, and a coarse tuft of hair, Dupin concludes the killer is an escaped Ourang-Outang.
- Falling The advertisement
He places a notice about a found Ourang-Outang to lure the owner, predicting a sailor will come to reclaim it.
- End The sailor’s confession
A Maltese sailor arrives, confirms the animal escaped with his razor and killed the women, and the wrongly held Le Bon is released.

Themes what the story is really about
Reason as a kind of art
Poe presents analysis not as cold calculation but as creative insight, a faculty that combines observation, imagination, and disciplined deduction.
Appearance versus evidence
The police see an impossible locked-room murder; Dupin shows that what looks supernatural is explained once every clue is read without prejudice.
The limits of common sense
Ordinary minds assume a human killer and a known language, and those assumptions blind them to a truth that lies outside expectation.
Justice and the innocent
An innocent clerk is jailed on circumstance, and only careful reasoning, not authority, restores justice.
Symbols & motifs
The locked room
The sealed apartment stands for a problem that seems impossible until the right method finds the hidden seam in it.
The conflicting voices
The witnesses’ disagreement over the shrill voice symbolizes how people impose familiar categories on what they cannot recognize.
The tuft of hair
The coarse, non-human hair is the concrete clue that overturns every human assumption about the crime.
The window nail
The broken spring-nail that lets a window seem sealed embodies the small overlooked detail on which the whole solution turns.
Recurring motifs
Reading the unreadable. Dupin repeatedly interprets signs others miss, from his friend’s thoughts to the marks at the crime scene.
Night and seclusion. The pair’s shuttered, candlelit existence recurs as the setting for a mind that works best withdrawn from the crowd.
Newspapers and testimony. Printed reports and quoted witnesses thread the story, raw data that Dupin sifts where others merely accept it.
Conflicts
Person versus problem
Dupin contends with a seemingly impossible locked-room mystery that resists the police and ordinary logic.
Person versus institution
Dupin’s private method stands against the Prefecture’s heavy-handed policing, which jails the wrong man.
Order versus chaos
The savage, animal violence threatens rational order until reason traces it to a natural, explainable source.
Literary devices
- Ratiocination
- Poe coins his showcase of step-by-step deductive reasoning, in which Dupin reconstructs events from physical evidence.
- Frame and essay opening
- The tale begins with a meditation on the analytic mind, framing the mystery as a demonstration of a thesis.
- The Watson-like narrator
- An admiring, less perceptive companion narrates, a device that lets Dupin explain his reasoning aloud to the reader.
- Red herring
- The inability of witnesses to place the strange voice misdirects toward a foreign human killer before the truth emerges.
- Foreshadowing
- The opening claims about analysis and the early thought-reading scene prepare the reader for Dupin’s climactic deductions.
Important quotes
“The mental features discoursed of as the analytical, are, in themselves, but little susceptible of analysis.”
“It appeared that there was no egress.”
““The hair,” I said, “is most unusual; this is no human hair.””
““Necessity, therefore, has brought him here.””
The solution dissolves the apparent impossibility by treating it as a chain of natural facts. Dupin shows that the room only seemed sealed: a window appeared nailed shut, but a broken spring let it close on its own after the killer left by the lightning rod. The witnesses’ failure to agree on the shrill voice was the decisive clue, because each heard a tongue they did not know, which suggested no human language at all. The superhuman strength, the agility needed to climb, and the coarse hair together point to an escaped Ourang-Outang, which had seized its master’s razor in imitation of shaving. By advertising a found ape, Dupin draws out the guilty animal’s owner, confirms the account, and clears the wrongly jailed Le Bon. The ending validates Poe’s opening claim that disciplined reason, joined to imagination, can read what brute investigation cannot.
Common misreadings
MythA human criminal committed the murders.
ActuallyDupin proves the killer was an escaped Ourang-Outang, which is why no human voice or motive fit the evidence.
MythThe room was truly impossible to enter or leave.
ActuallyA window with a hidden broken spring allowed an exit by the lightning rod, only appearing permanently sealed.
MythDupin is a police officer.
ActuallyHe is a private, eccentric gentleman who solves the case independently of, and despite, the official police.
Test yourself
1. What turns out to be the murderer in the story?
Dupin deduces, and the sailor confirms, that an escaped Ourang-Outang killed the women.
2. What clue first tells Dupin the killer is not human?
Along with the strength and strange voice, the non-human hair found at the scene is decisive.
3. How does Dupin draw out the animal’s owner?
Dupin advertises a found Ourang-Outang, predicting the valuable animal’s owner will come forward.
Two women are killed in a locked apartment in Paris, and the police are stumped because no one could have gotten in or out, and the witnesses heard a strange voice no one can identify. A clever man named Dupin studies the clues, figures out a window could secretly open, and realizes the strange voice and huge strength mean the killer was not a person at all. It was an escaped ape that had grabbed its owner’s razor. Dupin uses a newspaper ad to find the owner, and an innocent man who was arrested is set free. This is often called the very first detective story.
