The [boring] storyline basically goes like this:
Catherine1 and Hindley are brother and sister; Heathcliff is their adopted brother, about the same age as Catherine1. Catherine1 and Heathcliff are partners in mischief, get in trouble, and love each other, Hindley despises Heathcliff and degrades him. Edgar decides he wants to marry Catherine1, and against her better judgement, she marries him. Heathcliff is broken-hearted. Hindley marries a nasty girl; she dies in childbirth, giving birth to a son, named Hareton. Catherine1 and Edgar are happy, but she also dies in childbirth, giving birth to a daughter, Catherine2. Before Catherine1 and Edgar marry, Heathcliff leaves, and is gone for three years, before he returns to the Heights. When he gets there, he visits Catherine1 and Edgar, and is present when she loses consciousness for the last time, just before giving birth. Obviously, he and Edgar are sworn enemies. Heathcliff also gains control- legally- of all of Hindley's wealth, and thus retains that control for the remainder of the story, rendering all descendants of Catherine1 and Hindley (brother and sister) dependent on him, as their master.
Heathcliff marries Edgar's sister Isabella, and both are miserable. Isabella runs away, and a few months later gives birth to Heathcliff's son, Linton, who is a 'sickly, peevish child' [sic]. Isabella lives until Linton is twelve, at which point she dies (duh!), and calls Edgar to take her child and be with her when she dies. Edgar does so, and brings Linton, who is six months younger than Catherine2, home. He stays there for one night, until he is forced to go back to live with his father, Heathcliff.
Heathcliff has an idea that for the purposes of inheritance and making his enemies suffer, his sickly son, Linton, must marry Catherine2. He sets it up so that they have the opportunity to fall in love, which they do. Edgar Linton falls ill, and Heathcliff insists that Catherine2 not leave his home until she is married to Linton. She marries him, and escapes back home in time for her father and her to have one last meeting, while he is on the deathbed. She mourns. She is fetched back to her husband and father-in-law, and forced to take care of her husband for about a week, until his death. Though she did love him, she was forced into marriage, and afterwards, when her father-in-law and husband revealed their tyrannical natures, is miserable. After his death, she is kept as a ward who must earn her keep. Hareton, her other cousin, who also lives with them, is brutal to her face and defends her behind her back. He is also illiterate, which causes her to scorn him.
Eventually, Catherine2 teaches Hareton how to read, and they fall in love. Heathcliff dies, and then they marry a few months later. Heathcliff is buried next to his true love, Catherine1, who lies beside her husband. The side of her coffin and his are open, so that the bodies may disintegrate together. (I assume her husband lies on her other side.) With Heathcliff's death, the property transfers back to its rightful owner- namely, Hareton, Hindley's heir, and since Catherine2 is his wife, they both are rich, and live happily ever after, deserting the house which held so many awful memories.
Yippee! Was that interesting? No. It was well-written, but pointless and boring. However, now I can sign the paper attesting to the fact that I read the book, in its entirety, in English, answer the essay question, and be done.
Whoopee-do....
Fortunately, since this was my fifth book out of fifteen, I only have ten more left until I'm done. One of them, Billy Budd, seems pretty benign, even though it's even more boring than this and written in incomprehensible Old British English. At least it's only 70 pages...
