Book excerpt: Somebody—call him John Doe—has been shot in the head. With the bullet still lodged in his brain, he has lost his memory, but gained the ability to read minds. This new talent makes him a winner at high-stakes poker, then on the stock market, then as an international mediator for the U.S. government, where he becomes the center of an international intrigue. Finally, his brain flooded with endorphins, Jon Dough realizes that nothing is really as it seams.
