Linton Heathcliff is a son of Heathcliff and Isabella Linton. Isabella and Heathcliff do not enjoy a happy conjugal life and Isabella lives separately on her own, bringing up the child entirely by herself. The boy, growing up in the absence of the proper structure of a typical Victorian household and material lack suffers lack of nourishment and care, dying before he can sufficiently cross into adulthood.
As time passes in the story, Linton shows up to Wuthering Heights after the passing of his mother, Isabella. Linton is a weak young man, oftentimes very sick and soft-spoken. He despises his father, who only uses him to gain control of Thrushcross Grange.
One day, young Cathy is found in the woods nearby, looking for birds' nests, by Heathcliff and his son, Linton. They take her back to Wuthering Heights, where Heathcliff is very charming towards her, and Cathy gets a glance at Hareton for the first time, as well. Cathy returns home to tell her father of her time at Wuthering Heights, and that is when Cathy finds out more about the history between the two of them. Meanwhile, Linton writes a letter to Cathy, but in the words of his father, Heathcliff. It entices her to return to Wuthering Heights again, where Heathcliff then attacks her, locks her up in a room, and forces her to marry Linton while her father, Edgar is on his deathbed waiting for her return. Linton and Cathy get married, Edgar dies, then Linton dies, and Heathcliff is now the owner of Thrushcross Grange.
