Wuthering Heights ends with Heathcliff’s death, the younger generation’s tentative happy future, and a strong suggestion that Heathcliff and Catherine are spiritually reunited.

Final events in the story

  • Cathy Linton (Catherine’s daughter) and Hareton Earnshaw slowly move from hostility to friendship and then love, as she teaches him to read and they soften each other’s rough edges.
  • Heathcliff, having gained control of both Wuthering Heights and Thrushcross Grange, loses interest in his revenge; he becomes obsessed with the dead Catherine, sees her everywhere, and neglects food and sleep.
  • He grows physically weaker and more unhinged, talking to Catherine’s ghost and acting as if he is impatient to join her.
  • One night he is found dead in Catherine’s old room, with an expression of wild joy on his face and the window open, as if he has gone out to meet her.
  • Cathy and Hareton inherit both estates and plan to marry, symbolizing a break in the cycle of cruelty and vengeance and the start of a more peaceful future.
  • Locals report seeing the ghosts of Heathcliff and Catherine wandering the moors together, and Lockwood ends the book reflecting on the quietness of their graves and the sense of final peace.

Very short answer (no major spoilers beyond the core ending)

  • Heathcliff dies after yielding to his obsession with Catherine.
  • Cathy and Hareton fall in love and will marry, uniting the families.
  • The moors are left to the haunting, romantic legend of Catherine and Heathcliff’s spirits together.

TL;DR: Wuthering Heights ends with Heathcliff’s death, Cathy and Hareton’s planned marriage and inheritance of both houses, and the implied ghostly reunion of Catherine and Heathcliff on the moors, bringing a dark story to a strangely peaceful close.
