men still kept the positions that they had held when she had turned away. The newcomer's revolver still menaced the rustler. She looked up into Ferguson's face, to see a grim smile on it, to see his eyes, chilled and narrowed, fixed steadily upon the two horsemen.
"Oh!" she said, "is it over?"
Ferguson heard the question, and smiled mirthlessly without turning his head.
"I reckon it ain't over—yet," he returned. "But I expect it'll be over pretty soon, if that guy that's got his gun on the rustler don't get a move on right quick. That other guy is comin' around the corner of that break, an' if he's the rustler's friend that man with the gun will get his pretty rapid." His voice raised a trifle, a slightly anxious note in it.
"Why don't the damn fool turn around? He could see that last man now if he did. Now, what do you think of that?" Ferguson's voice was sharp and tense, and, in spite of herself, Miss Radford's gaze shifted again to the plains below her. Fascinated, her fear succumbing to the intense interest of the moment, she followed the movements of the trio.
From around the corner of the break the third man had ridden. He was not over a hundred feet from the man who had caught the rustler and he was walking his horse now. The watchers on the edge of the plateau could see that he had taken in the situation and was stealing upon the captor, who sat in his saddle, his back to the advancing rider.
Drawing a little closer, the third man stealthily dropped from his pony and crept forward. The significance of this movement dawned upon Miss Radford in a flash, and she again seized Ferguson's arm, tugging at it fiercely.
"Why, he's going to kill that man!" she cried. "Can't you do something? For mercy's sake do! Shout, or shoot off your pistol—do something to warn him!"
Ferguson flashed a swift glance at her, and she saw that his face wore a queer pallor. His expression had grown grimmer, but he smiled—a little sadly, she thought.
"It ain't a bit of use tryin' to do anything," he returned, his gaze again on the men. "We're two miles from them men an' a thousand feet above them. There ain't any pistol report goin' to stop what's goin' on down there. All we can do is to watch. Mebbe we can recognize one of them. . . . Shucks!"
The exclamation was called from him by a sudden movement on the part of the captor. The third man must have made a noise, for the captor turned sharply. At the instant he did so the rustler's pistol flashed in the sunlight.
The watchers on the plateau did not hear the report at once, and when they did it came to them only faintly—a slight sound which was barely distinguishable. But they saw a sudden spurt of flame and smoke. The captor reeled drunkenly in his saddle, caught blindly at the pommel, and then slid slowly down into the grass of the plains.
Ferguson drew a deep breath and, turning, looked sharply at Miss Radford. She had covered her face with her hands and was swaying dizzily. He was up from the rock in a flash and was supporting her, leading her away from the edge of the plateau. She went unresisting, her slender figure shuddering spasmodically, her hands still covering her face.
"Oh!" she exclaimed, as the horror of the scene rose in her mind. "The brutes! The brutes!"
Feeling that if he kept quiet she would recover from the shock of the incident sooner, Ferguson said nothing in reply to her outbreaks as he led her toward the ponies. For a moment after reaching them she leaned against her animal's shoulder, her face concealed from Ferguson by the pony's mane. Then he was at her side, speaking firmly.
"You must get away from here," he said, "I ought to have got you away before—before that happened."
She looked up, showing him a pair of wide, dry eyes, in which there was still a trace of horror. An expression of grave self-accusation shone in his.
"You were not to blame," she said dully. "You may have anticipated a meeting of those men, but you could not have foreseen the end. Oh!" She shuddered again. "To think of seeing a man deliberately murdered!"
"That's just what it was," he returned quietly; "just plain murder. They had him between them. He didn't have a chance. He was bound to get it from one or the other. Looks like they trapped him; run him down there on purpose." He held her stirrup.
"I reckon you've seen enough, ma'am," he added. "You'd better hop right on your horse an' get back to Bear Flat."
She shivered and raised her head, looking at him—a flash of fear in her eyes. "You are going down there!" she cried, her eyes dilating.
He laughed grimly. "I cert'nly am, ma'am," he returned. "You'd better go right off. I'm ridin' down there to see how bad that man is hit."
She started toward him, protesting. "Why, they will kill you, too!" she declared.
He laughed again, with a sudden grim humor. "There ain't any danger," he returned. "They've sloped."
Involuntarily she looked down. Far out on the plains, through the break in the ridge of hills, she could see two horsemen racing away.
"The cowards!" she cried, her voice shaking with anger. "To shoot a man in cold blood and then run!" She looked at Ferguson, her figure stiffening with decision.
"If you go down there I am going, too!" she declared. "He might need some help," she added, seeing the objection in his eyes, "and if he does I may be able to give it to him. You know," she continued, smiling wanly, "I have had some experience with sick people."
He said nothing more, but silently assisted her into the saddle and swung into his own. They urged the animals to a rapid pace, she following him eagerly.
It was a rough trail, leading through many gullies, around miniature hills, into bottoms where huge boulders and treacherous sand barred the way, along the face of dizzy cliffs, and through lava beds where the footing was uncertain and dangerous. But in an hour they were on the plains and riding toward the break in the ridge of hills, where the shooting had been done.
The man's pony had moved off a little and was grazing unconcernedly when they arrived. A brown heap in the grass told where the man lay, and presently Ferguson was down beside him, one of his limp wrists between his fingers. He stood up after a moment, to confront Miss Radford, who had fallen behind during the last few minutes of the ride. Ferguson's face was grave, and there was a light in his eyes that thrilled her for a moment as she looked at him.
"He ain't dead, ma'am," he said as he assisted her down from her pony. "The bullet got him in the shoulder."
She caught a queer note in his voice—something approaching appeal. She looked swiftly at him, suspicious. "Do you know him?" she asked.
"I reckon I do, ma'am," he returned. "It's Rope Jones. Once he stood by me when he thought I needed a friend. If there's any chance I'm goin' to get him to your cabin—where you can take care of him till he gets over this—if he ever does."
She realized now how this tragedy had shocked her. She reeled and the world swam dizzily before her. Again she saw Ferguson dart forward, but she steadied herself and smiled reassuringly.
"It is merely the thought that I must now put my little knowledge to a severe test," she said. "It rather frightened me. I don't know whether anything can be done."
She succeeded in forcing herself to calmness and gave orders rapidly.
"Get something under his head," she commanded. "No, that will be too high," she
