Nick can’t sleep and goes to Gatsby’s mansion. He tells him about his past and his love for Daisy. He found out she was going to marry Tom while he was in Oxford after the war. By the time he returned to the US, she was married.
The narrative shifts to George Wilson. He believes Myrtle was murdered by her lover, whom he believes to be the owner of the big yellow car. He sets off to find him. He catches up with Gatsby in the pool outside his home and shoots him dead, before killing himself.
Nick is left to organise Gatsby’s funeral. Daisy and Tom have left town. Wolfshiem refuses to come. Hundreds of people attended Gatsby’s parties but no-one comes to his funeral apart from Nick, Gatsby’s father, and some servants. A man called 'Owl-eyes', who did attend some of Gatsby's parties, arrives late.
Nick talks about two meetings he had after the accident, one with Jordan and the other with Tom. From Jordan, he finds out she is now engaged to someone. From Tom Buchanan he learns that Tom told George Wilson it was Gatsby who had been driving the car that killed Myrtle.
Nick then visits Gatsby’s mansion for one last time and recalls how it used to be during Gatsby’s parties before returning to the Midwest for good.
