The Sphinx Without a Secret by Oscar Wilde
Quick answer: The Sphinx Without a Secret by Oscar Wilde: full summary with the ending, Lady Alroy's mystery explained, themes, irony and the craft behind Wilde's shortest sting.
A beautiful widow rents a shabby room in a London side street, visits it heavily veiled, and does absolutely nothing there. That single image powers The Sphinx Without a Secret, one of Oscar Wilde's briefest stories, first printed in 1887 under the title Lady Alroy and later collected in Lord Arthur Savile's Crime and Other Stories in 1891. It runs only a few pages, which is part of why students and writers keep returning to it: the whole machine is visible at once.
Wilde is best known for epigrams and for The Picture of Dorian Gray, but this little story shows a different skill, the anecdote sharpened until it draws blood. It asks a question that outlives its Victorian setting: what if the air of mystery some people carry is the whole of them? Below you will find the complete plot including the ending, the characters, the standard exam themes, and the structural trick worth borrowing.
The story in brief, ending included
An unnamed narrator, idling in Paris, runs into his old friend Lord Murchison, who looks anxious and changed. Over dinner Murchison confesses the cause. Back in London he had fallen in love with Lady Alroy, a lovely, soft spoken widow he met by chance. From the start she behaved strangely: she asked him not to write to her at her own house, gave him an address for letters care of a stationer, and grew alarmed whenever their meetings risked being noticed. One day, by accident, Murchison saw her walking quickly through a dingy street, veiled, and watched her let herself into lodgings in Cumnor Street with her own key.
Convinced she was concealing a lover, he confronted her. She denied any wrongdoing but refused to explain the room, and he stormed off abroad in a rage. A month later Lady Alroy died of a chest illness. Unable to rest, Murchison went to the Cumnor Street house and questioned the landlady, who told him the plain truth: the lady rented the sitting room, came two or three times a week, sat alone, read a little, sometimes took tea, and saw no one. There was no lover and no crime. The narrator offers the verdict that gives the story its title: Lady Alroy was a sphinx without a secret, a woman with a mania for mystery who took a room so she could go there veiled and feel like the heroine of a novel. Murchison, still holding her photograph, answers only, 'I wonder?'
The characters and what they want
Three figures do all the work. Lord Murchison wants certainty: he can love Lady Alroy or condemn her, but he cannot bear not knowing which. Lady Alroy wants atmosphere: she seems to crave the sensation of having a secret more than any secret itself, and she protects the mystery even at the cost of the man who loves her. The narrator wants a tidy explanation, and he supplies one with a confidence the story quietly undercuts. The landlady, a minor fourth presence, matters because she is the only witness with no imagination at all, which is exactly why we believe her.
Themes and meaning
The obvious theme is the difference between mystery and secrecy. A secret is a fact withheld; mystery is a performance, and Lady Alroy performs it so completely that it consumes her marriage prospects and arguably her health. Wilde is also writing about how men read women: Murchison never asks who Lady Alroy is, only what she is hiding, and the story punishes that habit of mind. A third exam friendly theme is appearance versus reality, though Wilde gives it a twist, since here the reality behind the appearance is nothing at all.
The sharper observation is this: the story never actually settles its own question. The narrator's explanation is elegant, but it is still a man supplying a theory about a dead woman who can no longer answer, and Murchison's final 'I wonder?' reopens the case in the last breath. Wilde builds a story about interpretation and then leaves the reader holding the same unverifiable photograph Murchison holds. The title states a conclusion the text refuses to guarantee.
The craft: an anecdote with a delayed detonation
Structurally this is a frame story: a chance meeting in Paris opens a confession, and the confession contains the plot. The frame does two jobs. It lets Wilde compress months of courtship into summary without losing intimacy, and it plants a listener inside the story whose judgement the reader is tempted to adopt. The turn arrives exactly where a lesser writer would put the revelation of an affair; Wilde puts an empty room there instead, and the anticlimax lands harder than any scandal could.
The technique worth stealing is the withheld explanation that turns out to be a vacuum. Most twist stories replace a false explanation with a true one. Wilde replaces it with an absence, then lets a character paper over the absence with a witty theory. If you write contest fiction, notice how the story spends its ending: one line of interpretation, one line of doubt, and it stops. Judges who score structure notice endings that trust the reader this much.
Lines that carry it
The closing exchange does the heaviest lifting. The narrator's confident label, a 'sphinx without a secret', is quotable precisely because it sounds final, and Murchison's soft 'I wonder?' dissolves that finality in two words. Quote them together in an essay and you have the story's whole argument about interpretation in miniature: one voice that needs an answer, one voice that has learned to live without one.
What poets can take from this
- For exams, name the central irony precisely: the mystery is real but the secret does not exist.
- Cite the frame structure, since the Paris conversation makes the narrator an interpreter rather than a witness.
- Use the final 'I wonder?' as evidence that Wilde leaves the explanation open rather than settled.
- Writers: try ending a mystery with an absence instead of a revelation and see how much tension survives.
- Keep summaries of the courtship brief in essays; the meaning lives in the Cumnor Street room and the ending.
- Compare Lady Alroy with Dorian Gray if you need a second Wilde text on performance and concealment.
Try it yourself
Write a story in which one character becomes obsessed with discovering another person's secret, and the answer, when it finally arrives, is that there was never anything to find. Decide what the obsession was really about, and let the last line admit it.
Questions
What is the twist in The Sphinx Without a Secret?
Lady Alroy's mysterious rented room hides nothing: the landlady confirms she simply sat there alone. The twist is an anticlimax. The narrator concludes she loved the feeling of mystery itself, though Murchison's final 'I wonder?' leaves even that explanation uncertain.
What does the title The Sphinx Without a Secret mean?
The sphinx of legend poses riddles that conceal an answer. Lady Alroy poses as a riddle with no answer behind it, a performance of mystery with nothing concealed. The title is the narrator's verdict on her character, delivered after her death.
Why does Lady Alroy rent the room in Cumnor Street?
According to the landlady she used it only to sit alone, read and take tea. The narrator's theory is that she had a mania for mystery and wanted to feel like the veiled heroine of a novel. Wilde never lets her explain herself, which is part of the story's point.
