In 1924, F. Scott Fitzgerald told his editor Maxwell Perkins about a young American expatriate in Paris, an unknown writer with a "brilliant future". When Perkins wrote to Ernest Hemingway several months later, he began a correspondence spanning more than two decades and charting the career of one of the most influential American authors of this century. The letters collected here are the record of that professional alliance and of Hemingway's development as a writer.
