Catherine's death and its significance in Emily Bronte's, Wuthering Heights.

In Part II, Catherine and Edgar are married and seem happy, until Heathcliff returns, mysteriously wealthy and educated. He takes up residence at Wuthering Heights, where he gambles Hindley out of all his possessions. Heathcliff quickly resumes his acquaintance with Catherine, to her delight and Edgar's annoyance. Isabella, Edgar's sister, begins to love Heathcliff, in spite of repeated warnings about his character. Heathcliff, desiring Isabella's inheritance, begins to encourage the attraction, and when Nelly informs Edgar of this courtship he becomes enraged. A fight ensues between Edgar and Heathcliff, and Heathcliff is banished from the Grange. Catherine, to punish Edgar, refuses to eat for three days and drives herself into a feverish delirium. While Edgar is nursing her back to a fragile state of health, Isabella and Heathcliff elope. Isabella soon regrets her marriage to the cruel Heathcliff. She writes to Nelly, telling her of her miserable life at Wuthering Heights and begging her to visit. Heathcliff takes advantage of Nelly's visit to request a meeting with Catherine, who is pregnant. Nelly reluctantly agrees, and a few days later, while Edgar is at church, Heathcliff enters the Grange and sees Catherine for the last time. Edgar enters and finds Heathcliff embracing Catherine, who has fainted. Catherine dies without ever fully regaining her senses, although two hours before her death, she gives birth to a daughter. Edgar and Heathcliff are both distraught at Catherine's death, and Heathcliff begs her ghost to haunt him.
