At the very end of Chapter Three of “The Great Gatsby,” Nick Carraway finally discovers what it is about Jordan Baker that has been haunting him ever since he met her at The Buchanan’s that first day. He remembers seeing her picture in a paper and it was a “critical, unpleasant story,” but he couldn’t remember the specifics until later.
It was after the party that Gatsby gave and Nick was walking back to the house he had rented. Thinking of Jordan, he finally remembered the incident. The memory was brought back when Jordan lied about leaving the top down on a car she had borrowed and left in the rain. Nick remembered the scandal about her cheating at her first golf tournament, and realized that Jordan was “incurably dishonest.”
