A suspicion flashed through the mind of Avon. The man was an Indian beyond question, and the horse could not be his own, for, if it were, he would have obeyed him without urging. It must be one of the Texan horses that he was trying to steal.
The youth uttered the familiar signal by which he was able at all times to bring Thunderbolt to his side, when he was within hearing. The mustang replied with a glad whinny, and broke into a trot straight for his master. It was indeed his prized animal, with a Comanche warrior on his back.
CHAPTER XXIII.
“GOOD-BY!”
The Comanche must have been disgusted. He had been trying for some time to steal the mustang of Avon Burnet, with the result that the pony was about to steal him, unless he prevented it offhand.
The Indian heard the whistle from the edge of the bush, and the instant increase of speed, on the part of the stubborn mustang, made the meaning clear to him. He did not know but that three or four Texans were waiting in the mesquite, and that, if he stayed on the back of the steed a minute longer, he would be carried directly into their arms.
Consequently he did not hesitate. He went off of Thunderbolt, as if struck by a cannon ball, and, heading out on the prairie, ran with might and main, quickly disappearing in the darkness, and was seen no more.
