As Tom's car nears Wilson's garage, they can all see that some sort of accident has occurred. Pulling over to investigate, they learn that Myrtle Wilson, Tom's mistress, has been hit and killed by a passing car that never bothered to stop, and it appears to have been Gatsby's car. Tom, Jordan, and Nick continue home to East Egg. Nick, now disgusted by the morality and behavior of the people with whom he has been on friendly terms, meets Gatsby outside of the Buchannans house where he is keeping watch for Daisy. With a few well-chosen questions, Nick learns that Daisy, not Gatsby, was driving the car, although Gatsby confesses he will take all the blame. Nick, greatly agitated by all that he has experienced during the day, continues home, but an overarching feeling of dread haunts him.
Nearing dawn the next morning, Nick goes to Gatsby's house. While the two men turn the house upside down looking for cigarettes, Gatsby tells Nick more about how he became the man he is and how Daisy figured into his life. Later that morning, while at work, Nick is unable to concentrate. He receives a phone call from Jordan Baker, but is quick to end the discussion — and thereby the friendship. He plans to take an early train home and check on Gatsby.
The action then switches back to Wilson who, distraught over his wife's death, sneaks out and goes looking for the driver who killed Myrtle. Nick retraces Wilson's journey, which placed him, by early afternoon, at Gatsby's house. Wilson murders Gatsby and then turns the gun on himself.
