The most famous book narrates the life of Nick Carraway, who watches Gatsby. The narrator is Nick. He states that he is not going to judge anyone till after the conclusion, yet his whole story is an evaluation concerning Gatsby.
Concept: Nick is a trustworthy but untrustworthy narrator due to his bias. He is a flawed filter of the story. We have the truth, but it is the subjective truth of a prejudiced friend.
