The Great Gatsby pt4

As the novel progresses, Fitzgerald builds mystery around Gatsby's character; he keeps him in the dark, not only for us but for Nick too. In the first few chapter a lot is said and thought about Gatsby, but never by Gatsby himself. Nick and Gatsby eventually go to lunch together in the city and on the drive there, Gatsby tells him about his past and personal life but everything he says seems very improbable to Nick. That irritates Gatsby and makes him want to prove himself to the narrator. When they finally arrive, Gatsby introduces the narrator to a shady, New York city entrepreneur. Seeing the two men being friendly, Nick begins to suspect that Gatsby's wealth might be shadier than people think (organized crime?).
