Chapters 4 to 17
The story begins thirty years before when the Earnshaw family lived at Wuthering Heights consisting of, as well as the mother and father, Hindley, a boy of fourteen, and six-year-old Catherine, the same person that he had dreamt about and the mother of the present mistress. In that year, Mr. Earnshaw travels to Liverpool where he finds a homeless, gypsy-like boy of about seven whom he decides to adopt as his son. He names him ‘Heathcliff’. Hindley, who finds himself excluded from his father’s affections by this newcomer, quickly learns to hate him but Catherine grows very attached to him. Soon Heathcliff and Catherine are like twins, spending hours on the moors together and hating every moment apart.
Because of this discord, Hindley is eventually sent to college, but he returns, three years later, when Mr. Earnshaw dies. With a new wife, Frances, he becomes master of Wuthering Heights and forces Heathcliff to become a servant instead of a member of the family.
Two years on and Catherine has become close friends with Edgar, growing more distant from Heathcliff. One day in August, while Hindley is absent, Edgar comes to visit Catherine. She has an argument with Ellen which then spreads to Edgar who tries to leave. Catherine stops him and, before long, they declare themselves lovers.
Later, Catherine talks with Ellen, explaining that Edgar had asked her to marry him and she had accepted. She says that she does not really love Edgar but Heathcliff. Unfortunately, she could never marry the latter because of his lack of status and education.
Six months after the marriage, Heathcliff returns as a gentleman, having grown stronger and richer during his absence. Catherine is delighted to see him although Edgar is not so keen. Isabella, now eighteen, falls madly in love with Heathcliff, seeing him as a romantic hero. He despises her but encourages the infatuation, seeing it as a chance for revenge on Edgar. When he embraces Isabella one day at the Grange, there is an argument with Edgar which causes Catherine to lock herself in her room and fall ill.
Heathcliff has been staying at the Heights, gambling with Hindley and teaching Hareton bad habits. Hindley is gradually losing his wealth, mortgaging the farmhouse to Heathcliff to repay his debts.
While Catherine is ill, Heathcliff elopes with Isabella, causing Edgar to disown his sister. The fugitives marry and return two months later to Wuthering Heights. Heathcliff hears that Catherine is ill and arranges with Ellen to visit her in secret. In the early hours of the day after their meeting, Catherine gives birth to her daughter, Cathy, and then dies.
