In the end, does Gatsby die?

He does. Gatsby is murdered by George Wilson, Myrtle Wilson's husband. Gatsby's car hits Myrtle as it travels through the "valley of ashes," but it is Daisy, not Gatsby, who is driving it.

George Wilson, in his grief over his wife, believes that Myrtle was running out of the garage to talk to Gatsby. After he finds an expensive dog leash among her belongings, he also believes that Myrtle and Gatsby were having an affair.

George travels to West Egg and shoots Gatsby as he floats on a raft in his swimming pool. He then shoots himself.
