Edgar sends a letter from London announcing that Isabella is dead and that he will be returning with her son, Linton Heathcliff. They finally arrive, and Cathy excitedly meets her cousin, a "pale, delicate, effeminate boy" (19.9).
Joseph comes down from the Heights to take Linton home to his father. Edgar feels terrible, because he had promised Isabella that he would watch over her son. But he has no choice—Heathcliff is the boy's father, after all.
Edgar tells him the boy will come to the Heights the next day.
