From 1919 to 1927, Jack Dempsey was the heavyweight champion of the world. With his fierce good looks and matchless dedication to the kill, he was a fighter perfectly suited to the Roaring '20s. In A Flame of Pure Fire, award-winning and renowned sports writer Roger Kahn, a personal friend of Dempsey's, tells the extraordinary story of a man and a country growing to maturity in a blaze of strength and exuberance. With passion and precision, Kahn not only chronicles the thrilling, brutal bouts of the "Manassa Mauler" but also illustrates how the wild and raucous 1920s shaped Dempsey, and how the champ, in turn, left an indelible mark on sports and American history. An accomplished and insightful observation on how sports can measure a society's evolution, Roger Kahn finds the heart of America in the story of the most famous athlete of his time, the man John Lardner once called "a flame of pure fire, at last a hero."
