Chapters 1-3:

The story of Wuthering Heights is narrarated by a young man named Mr. Lockwood. He has recently moved into a rented home known as Thrushcross Grange., owned by a Mr. Heathcliff of Wuthering Heights. Mr.s Lockwood decides to pay his landlord a visit and is surprised to discover how dark Mr. Heathcliff is, and how closed off his household is. Later when Mr. Lockwood has returned home, he inquires of his servent, Ellen Dean (Nelly for short), if she knows anything about his strange secluded landlord. Mrs. Dean, as it turns out, used to live and work at Wuthering Heights when Heathcliff was growing up, and she then procceeds to tell Mr. Lockwood all about Heathcliff's history, and so begins the story of Wuthering Heights.
Personally I love the way Wuthering Heights was written, with someone telling the narrarator the story from a second person perspective. I think this makes the story seem more realistic, it also makes the story more interesting because the reader is able to gain more insight into more of the characters.
