Plot Summary
Chapter 21 of Wuthering Heights opens with Nelly Dean reporting that young Cathy Linton was heartbroken when her cousin Linton Heathcliff was taken to live at Wuthering Heights. Over time, however, her memory of him fades. Nelly learns from the Heights housekeeper that Linton is sickly, selfish, and largely despised by his father Heathcliff, who can barely tolerate his presence. Meanwhile, Hareton Earnshaw, though rough and uneducated, shows a better nature—yet Heathcliff has deliberately degraded him into coarseness.
On Cathy's sixteenth birthday—also the anniversary of her mother's death—she and Nelly venture onto the moors while Edgar Linton visits Gimmerton kirkyard in private mourning. Cathy ranges far beyond the allowed distance and stumbles onto Heathcliff's land, where he intercepts her. Despite Nelly's protests, Heathcliff lures them into Wuthering Heights so that Cathy and Linton can be reunited. He privately confides to Nelly his scheme: he wants the two cousins to fall in love and marry so that he can secure the Linton property through their union, since Edgar's will would otherwise leave the estate beyond his reach.
Inside, Cathy joyfully recognises Linton, now taller but languid and frail. When she also meets Hareton, she and Linton cruelly mock his inability to read the inscription above the door, laughing at his Yorkshire dialect and rough manners. Hareton retreats in humiliated rage, while Heathcliff watches with mixed feelings—contempt for Linton's pettiness and a grim satisfaction that he has degraded Hareton even more thoroughly than Hindley once degraded him. In a chilling soliloquy, Heathcliff compares the two boys: Linton is "tin polished to ape silver," while Hareton is "gold put to the use of paving-stones"—a boy with first-rate qualities deliberately ruined.
Character Development
Cathy Linton is portrayed as vibrant, impulsive, and sheltered—"a happy creature, and an angel"—but her quick mockery of Hareton reveals an inherited class snobbery that mirrors the Linton family's worst tendencies. Linton Heathcliff appears briefly charming but fundamentally weak and spiteful, bonding with Cathy only through their shared cruelty toward Hareton. Hareton, though inarticulate and sensitive to slights, emerges as the chapter's most sympathetic figure—a victim of systematic degradation who still retains a core of decency. Heathcliff reveals the calculated depth of his revenge: he has ruined Hareton not from hatred but from a desire to mirror and surpass the injustice done to him by Hindley, and he manipulates Cathy and Linton as pawns in a property scheme. Edgar Linton, though loving, proves "too timid" to explain his fears about Heathcliff convincingly to his strong-willed daughter.
Themes and Motifs
deepens the novel's exploration of cyclical revenge: Heathcliff's degradation of Hareton repeats Hindley's degradation of Heathcliff, while Cathy and Linton's mockery of Hareton echoes the class prejudice that once wounded Heathcliff himself. The education and literacy motif surfaces powerfully when Hareton cannot read the Earnshaw name above his own ancestral door—a symbol of how completely he has been severed from his birthright. The chapter also develops the theme of secrecy and forbidden connection: Heathcliff urges Cathy to keep her visit secret, Cathy begins a clandestine correspondence with Linton, and Nelly discovers and destroys the hidden love letters. The burning of the letters foreshadows the destructive consequences of the relationship Heathcliff is engineering.
Literary Devices
employs vivid metaphor in Heathcliff's comparison of Hareton to "gold put to the use of paving-stones" and Linton to "tin polished to ape a service of silver," encapsulating his perverse pride in corrupting genuine worth. The chapter's dramatic irony is acute: readers understand Heathcliff's manipulative intent while Cathy remains innocently trusting, calling him "uncle" and proposing future visits. The parallel structure of the birthday—celebrating Cathy's life on the anniversary of her mother Catherine's death—reinforces the novel's pattern of love intertwined with loss. Simile enriches Nelly's narration throughout: Cathy runs "like a young greyhound" with a cheek "as soft and pure in its bloom as a wild rose," and her discovery that her letters are gone is compared to a bird "flying back to a plundered nest." The secret correspondence and its fiery destruction serve as a potent symbol of the doomed passion that Heathcliff's scheme will ignite between the cousins.
