Who is miss barker from The Great Gatsby?

Jordan Baker is a friend of Daisy Buchanan, a woman with whom Nick becomes romantically involved during the course of the novel. A competitive golfer, Jordan represents one of the "new women" of the 1920s-cynical, boyish, and self-centered. Jordan is beautiful, but also dishonest: she cheated in order to win her first Golf tournament and continually bends the truth.
