Daisy is the person who causes the death of Myrtle Wilson. However, this truth stays unrevealed. Daisy drives the car, which belongs to Gatsby, at this tragic moment. And he is determined to protect her and takes the blame upon himself.
Detailed answer:
Myrtle tragically dies of being hit by Gatsby’s car. But it is Daisy who is behind the wheel on the way to East Egg. She is allowed to do it to help settle her nerves. Before the accident, Myrtle notices Tom going around the city in Gatsby’s car. Then, she sees it again from the window and supposes Tom is driving. Determined to draw his attention, the silly girl runs into the middle of the road. Such behavior appears to be too sudden for Daisy. That is why she hits Myrtle with the vehicle and, thereby, kills the woman, who dies instantly.
The truth about the murderer stays unrevealed. Despite Nick’s advice to leave the town, Gatsby stays, willing to make sure Daisy is safe. The husband of the decent, George Wilson, is devastated by this tragic news. He is obsessed with the idea of finding the murderer and burns with revenge. George intends to kill the offender. Later, he receives false information from Tom about Gatsby’s guilt in the accident. It helps him find the car owner almost instantly. In the end, Wilson, assuming that the driver of the car is also Myrtle’s lover, shoots Gatsby and commits suicide.
