Quite unexpectedly, Isabella arrives at the Grange in a state of physical disarray. She knows better than to think Edgar will allow her to stay, so she is not seeking refuge, just assistance. She tells Nelly that Hindley stayed sober to attend his sister's funeral, but lost his courage and started drinking the morning of the service. When Heathcliff returns to Wuthering Heights from keeping vigil at Catherine's grave, Hindley locks him out of the house and tells Isabella that he is going to kill Heathcliff. Isabella tells Heathcliff of Hindley's intentions but does not allow him entrance to the house.
Heathcliff bursts into the house through a window and ends up beating Hindley. The next morning Isabella accuses Heathcliff of being responsible for everyone's misery and tells Hindley how Heathcliff beat him. Heathcliff and Hindley begin fighting again as Isabella makes her escape. After telling her story to Nelly, she leaves for London. She ends up giving birth to a son, Linton. Edgar and she begin corresponding, though he withdraws from society. Thirteen years later, Isabella dies.
Hindley dies six months after Catherine's death, and Nelly returns to Wuthering Heights to check on both funeral arrangements and Hareton. Nelly finds out that Hindley was deep in debt and that Heathcliff held the mortgage. Heathcliff refuses to allow Hareton to go with Nelly, threatening to take possession of Linton.
