Walker spent that summer nodding out all over the house, scarcely able to keep his head up. He'd become sick and ­monstrous-looking. Pallid but for his purple-veined nose, he tried to add color in his cheeks by scrubbing them with Borax powder. His top teeth had fallen out, and his dental implants wouldn't stay in, leaving him a mouthful of titanium pegs. Walker was beginning to shut out longtime friends, dismissing them as either ­money-grubbers or unwilling to "ride with the brand" – traitors, in cowboy lingo. His paranoia was so extreme that he lugged a huge case of guns wherever he traveled. He'd come to think himself so capable that when he accidentally cut his thumb to the bone, and the wound became infected, Walker performed surgery on it himself in a Las Vegas hotel room, using a scalpel from a 19th-century surgical kit he'd bought at auction. He had no fear of death, he'd told Todd, because years earlier, while in India, he had learned to stop and start his own heart. "The monks were amazed," Walker slurred.
