Plot Summary (OCR A-Level English Literature): Revision Notes
Plot summary
Oscar Wilde's An Ideal Husband is a four-act comedy of manners that explores themes of blackmail, moral perfection, and social hypocrisy in Victorian high society. The play follows the unravelling and eventual restoration of Sir Robert Chiltern's reputation and marriage when his corrupt past comes to light.
Setting and main characters
The play is set in fashionable Grosvenor Square, London, primarily in the home of Sir Robert Chiltern, a respected member of the House of Commons. The main characters include:
- Sir Robert Chiltern: A distinguished politician with a hidden past
- Lady Gertrude Chiltern: Sir Robert's morally rigid wife who expects absolute perfection
- Lord Goring: A dandified bachelor and close friend of the Chilterns who serves as the voice of reason
- Mrs. Cheveley: The antagonist who was Lady Chiltern's enemy from their school days
- Mabel Chiltern: Sir Robert's lively younger sister
- Lord Caversham: Lord Goring's father
The contrast between characters is essential to understanding the play's central conflicts: Sir Robert's hidden corruption versus Lady Chiltern's moral rigidity, and Lord Goring's worldly wisdom versus the prevailing social hypocrisy of Victorian society.
Act I: The blackmail plot begins
The play opens at a dinner party hosted by Sir Robert and Lady Chiltern. Among the guests are Lord Goring, described as a dandified bachelor, and Mrs. Cheveley, who arrives with sinister intentions.
Mrs. Cheveley's scheme
During the evening, Mrs. Cheveley reveals her plan to blackmail Sir Robert. She demands that he support a fraudulent scheme to build a canal in Argentina. Her leverage is damning: years earlier, Sir Robert had sold a Cabinet secret to Baron Arnheim (Mrs. Cheveley's late mentor), which allowed Arnheim to invest in Suez Canal stocks three days before the British government publicly announced its purchase. Sir Robert built his entire fortune on this illicit transaction, and Mrs. Cheveley possesses the incriminating letter as proof.
Sir Robert's entire political career and fortune are built on a foundation of corruption - he sold government secrets for personal gain. This revelation threatens to destroy everything he has achieved over the years.
The moral dilemma
Terrified of losing both his career and his marriage, Sir Robert agrees to Mrs. Cheveley's demands. However, Lady Chiltern learns of her husband's apparent change of heart regarding the canal scheme. Unaware of the blackmail plot or her husband's corrupt past, she insists he withdraw his support immediately.
For Lady Chiltern, their marriage depends on having an 'ideal husband' - a man who is morally perfect in both his private and public life. She cannot accept any compromise on ethical matters, demanding that Sir Robert remain 'unimpeachable in all his decisions'. Sir Robert reluctantly complies with his wife's wishes, seemingly sealing his doom.
The mysterious brooch
Near the end of the act, Mabel and Lord Goring discover a diamond brooch that Goring had given to someone many years ago. Goring takes possession of the brooch and asks Mabel to inform him if anyone comes looking for it - a detail that will prove crucial later.
Act II: Exposure and confrontation
The second act continues at Sir Robert's house, where tensions escalate dramatically.
Lord Goring's advice
Lord Goring urges Sir Robert to resist Mrs. Cheveley's blackmail and confess the truth to Lady Chiltern. During their conversation, Goring reveals that he and Mrs. Cheveley were once engaged, adding another layer of complexity to their relationship. After speaking with Sir Robert, Goring engages in playful flirtation with Mabel and takes Lady Chiltern aside, subtly encouraging her to be less morally rigid and more forgiving.
Lord Goring's role as the voice of reason becomes clear in this act. Unlike Lady Chiltern's rigid morality, he understands human weakness and advocates for forgiveness over absolute moral perfection.
The secret revealed
Mrs. Cheveley returns unexpectedly, claiming to search for a brooch she lost the previous evening. Furious at Sir Robert's betrayal of their agreement, she exposes his corrupt past to Lady Chiltern in front of Sir Robert. Unable to reconcile her image of her husband with this new reality, Lady Chiltern denounces Sir Robert and refuses to forgive him. The act ends with their marriage in crisis.
Act III: Lord Goring's clever trap
The third act shifts to Lord Goring's home, where a series of complications and misunderstandings occur.
A compromising letter
Lord Goring receives a letter from Lady Chiltern asking for his help. Written on pink paper, the letter could easily be misinterpreted as a romantic communication. Shortly after receiving it, Goring is interrupted by visits from his father, Lord Caversham (who demands to know when his son will marry), and Sir Robert (seeking further counsel).
Mistaken identities
Meanwhile, Mrs. Cheveley arrives unexpectedly. The butler, believing she is the woman Lord Goring has been expecting, shows her into the drawing room. While waiting alone, Mrs. Cheveley discovers Lady Chiltern's letter. When Sir Robert stumbles upon Mrs. Cheveley in Goring's drawing room, he jumps to the wrong conclusion, assuming his friend is having an affair with his enemy. He storms out angrily.
The misunderstandings in this act demonstrate Wilde's masterful use of comedic timing and dramatic irony. Each character operates with incomplete information, leading to false conclusions that heighten the tension and complicate the plot.
The brooch trap
When Lord Goring finally confronts Mrs. Cheveley, she makes a shocking proposal: claiming she still loves him from their past courtship, she offers to exchange Sir Robert's incriminating letter for Goring's hand in marriage. Lord Goring refuses, accusing her of degrading love by treating it as a vulgar transaction.
Then Goring springs his carefully prepared trap. He removes the diamond brooch from his desk and fastens it to Mrs. Cheveley's wrist using a hidden locking device. He reveals that Mrs. Cheveley had stolen this brooch from his cousin years ago. To avoid being arrested for theft, Mrs. Cheveley must hand over Sir Robert's letter in exchange for her release from the jewelled handcuff.
The brooch becomes the key to defeating Mrs. Cheveley's blackmail. By proving she is a thief, Lord Goring gains the leverage needed to force her to surrender Sir Robert's incriminating letter. However, this victory proves temporary when she steals Lady Chiltern's letter in retaliation.
After obtaining and burning the incriminating letter, Goring believes he has won. However, Mrs. Cheveley retaliates by stealing Lady Chiltern's letter from his desk, planning to send it to Sir Robert and make it appear as if his wife and Lord Goring are having an affair. She exits triumphantly.
Act IV: Resolution and reconciliation
The final act returns to Grosvenor Square, where all the plot complications are resolved.
Multiple revelations
Lord Goring proposes to Mabel, and she accepts. Lord Caversham brings news that Sir Robert has publicly denounced the Argentine canal scheme before the House of Commons, restoring his political integrity. Lady Chiltern then appears, and Lord Goring informs her that he has destroyed Sir Robert's incriminating letter but that Mrs. Cheveley has stolen her letter and plans to use it maliciously.
The misunderstood letter
At that moment, Sir Robert enters reading Lady Chiltern's letter, but he has completely misinterpreted it as a letter of forgiveness addressed to him rather than a request for help addressed to Lord Goring. This happy misunderstanding allows the couple to reconcile.
The misinterpretation of Lady Chiltern's letter represents one of Wilde's signature comic devices - a fortunate accident that resolves what could have been a devastating revelation. Sir Robert's mistaken reading saves both his marriage and Lord Goring's reputation.
Lady Chiltern's final test
In a moment that tests her moral growth, Lady Chiltern attempts to persuade Sir Robert to abandon his political career entirely, believing it to be tainted. However, Lord Goring intervenes, arguing that Sir Robert should continue his public service. This represents a shift in Lady Chiltern's rigid moral stance.
Final obstacle overcome
When Sir Robert initially refuses to allow Lord Goring to marry his sister Mabel, still believing Goring has been involved with Mrs. Cheveley, Lady Chiltern is forced to explain the previous night's events and the true nature of her letter. Understanding the truth at last, Sir Robert gives his blessing to the match between Lord Goring and Mabel.
The play concludes with all conflicts resolved: Sir Robert's political career is saved, his marriage is restored, and Lord Goring and Mabel are permitted to wed.
Key themes and plot devices
The brooch as symbol
The diamond brooch serves as both a plot device and a symbol throughout the play. Originally a gift from Lord Goring, it was stolen by Mrs. Cheveley, and its eventual recovery becomes the means by which Goring outmanoeuvres her blackmail plot. The brooch represents both hidden guilt and the evidence needed to expose wrongdoing.
Letters as complications
Two crucial letters drive the plot: Sir Robert's incriminating letter about the Cabinet secret (which proves his corruption) and Lady Chiltern's ambiguous letter to Lord Goring (which could be read as either a plea for help or a love letter). Both letters demonstrate how written communication can be misinterpreted and manipulated.
Wilde uses letters as dramatic devices to create tension and drive the plot forward. In Victorian society, written correspondence carried significant social weight, and the potential for misinterpretation made letters particularly dangerous - especially for women, whose reputations could be ruined by even the appearance of impropriety.
The concept of the 'ideal husband'
Central to the play is Lady Chiltern's notion of an 'ideal husband' - a partner who must be morally perfect in every aspect of life. The play challenges this unrealistic standard, suggesting that forgiveness and understanding are more important than impossible perfection. Lady Chiltern's character arc involves learning to accept human fallibility.
The play's title is deeply ironic. Wilde suggests that the pursuit of an "ideal husband" - or any ideal of moral perfection - is not only impossible but potentially destructive. True love requires accepting human weakness and offering forgiveness rather than demanding impossible standards of behavior.
Moral rigidity versus forgiveness
The conflict between Lady Chiltern's strict moral code and the more flexible, worldly philosophy represented by Lord Goring drives much of the drama. Wilde suggests that absolute moral standards are not only unrealistic but potentially destructive to relationships and happiness.
