He paused to make sure that his mask was snugly in place. It had become so much a part of him that he couldn't be sure of its presence unless he felt it with his hand. When Tonto had, at first, suggested wearing the mask all the time, he had thought it a bit dramatic, perhaps even silly, but consideration made him realize that he already was hampered by the determination not to shoot to kill, by great odds, and by the weakness of his wounds and recent fever. He might have to fight, to rope and shoot, and the mask must be no handicap. He checked his guns, making sure that they were fully loaded by replacing the shell that had been used to disarm Rangoon. Then he was ready. An experienced black cat stalking a nervous bird could be no more quiet than was the Lone Ranger as he moved across the Basin. His clothing had no flapping superfluities; he wore no jingling spurs; his guns were tied down so that the holsters could not slap his legs. Boots oiled to preclude the slightest possibility of any squeaking leather, he moved swiftly and surely toward the buildings of the ranch. He saw the house and, not far from it, the row of lighted squares that marked the bunkhouse. Halfway to the buildings, the Lone Ranger froze. He wondered if his eyes were playing tricks, or if he actually had seen someone, or something, move at one end of the bunkhouse. Now he saw a moving figure in the beam of light that slanted from a rear window. In an instant, whatever he saw was obscured by the darkness. He glanced over his shoulder. Silver was well out of sight. His own dark clothing would be barely visible unless someone were quite close to him. Then he heard the sound of hoofs. A horse and rider appeared as a vague shadow against the lighted bunkhouse windows. The masked man dropped flat on his stomach, hugging the ground as closely as possible. The rider was coming straight toward him. He drew a pistol, holding it in readiness if he should be seen. He knew that his hat was light, and might attract attention, but he dared not move it. He felt the ground tremble with the beat of hoofs. He heard the crack of a quirt, cruelly applied, and a man's husky voice. Now the rider was almost upon him, without slackening his speed. The racing horse looked tremendous as it passed within twenty feet of the Lone Ranger. It was impossible to tell who was in the saddle. All details were shrouded by the darkness, but whoever that horseman was, he was in a hurry. He swept across the Basin toward the foot of Thunder Mountain, and the last the masked man saw was the barely perceptible shadow breaking through the underbrush that hid the uphill trail. The Lone Ranger presently rose to his feet, waited several seconds, and then moved ahead again. This time his destination was the bunkhouse. He could call on Bryant and Penelope later. First, he would investigate to learn, if possible, the reason for the unknown rider's sudden departure.
