In the wake of the stock-market crash and the dawn of the Great Depression, a ray of light emerged from the world of sports. In the summer of 1930, Bobby Jones, a 28-year-old amateur golfer, mounted a campaign against the record books. In four months, this natural, self-taught player conquered the British Amateur Championship, the British Open, the United States Open, and finally the United States Amateur Championship, an achievement so extraordinary that writers dubbed it the Grand Slam. No one has ever repeated it.

Yet, soon after the Grand Slam, Jones made the shocking announcement that he was retiring from the game. His abrupt disappearance from the public eye helped create the mythological image of this hero from the Golden Age of sports that endures to this day. Mark Frost uses a wealth of original research to provide an unprecedented intimate portrait of golf great Bobby Jones.
