By the next autumn she was gay again, gay as ever. She had a debut after the Armistice, and in February she was presumably engaged to a man from New Orleans. In June she married Tom Buchanan of Chicago, with more pomp and circumstance than Louisville ever knew before. He came down with a hundred people in four private cars, and hired a whole floor of the Seelbach Hotel, and the day before the wedding he gave her a string of pearls valued at three hundred and fifty thousand dollars.
– F. Scott Fitzgerald
