In the preface to A Moveable Feast, Hemingway remarks casually that "if the reader prefers, this book may be regarded as fiction"--and, indeed, fact or fiction, it doesn't matter, for his slim memoir of Paris in the 1920s is as enchanting as anything made up and has become the stuff of legend. Paris in the '20s! Hemingway and his first wife, Hadley, lived happily on $5 a day and still had money for drinks at the Closerie des Lilas, skiing in the Alps, and fishing trips to Spain. On every corner and at every caf� table, there were the most extraordinary people living wonderful lives and telling fantastic stories. Gertrude Stein invited Hemingway to come every afternoon and sip "fragrant, colorless alcohols" and chat admid her great pictures. He taught Ezra Pound how to box, gossiped with James Joyce, caroused with the fatally insecure Scott Fitzgerald (the acid portraits of him and his wife, Zelda, are notorious). Meanwhile, Hemingway invented a new way of writing based on this simple premise: "All you have to do is write one true sentence. Write the truest sentence you know." Hemingway beautifully captures the fragile magic of a special time and place, and he manages to be nostalgic without hitting any false notes of sentimentality. "This is how Paris was in the early days when we were very poor and very happy," he concludes. Originally published in 1964, three years after his suicide, A Moveable Feast was the first of his posthumous books and remains the best. --David Laskin
