Then he brushed the dirt from his coat and straightened out his tumbled appearance as best he could. His horse was tied to the gate post a hundred yards along the road. He slunk toward it, climbed into the saddle, and rode slowly away in the falling twilight. He had been thoroughly sobered by the incident, yet continued somewhat dazed, for his horse was headed toward the woods and hills and not in the direction of home. CHAPTER XII—The Sped Bullet MEANWHILE events had been happening in the conning tower high up among the hills. The Mexican boy on duty had observed the lone rider approaching the gateway at La Siesta, and for a brief few moments had put the figure under observation by the telescope. He had then sprung alertly erect and pressed a button on the wall. Mr. Robles had quickly responded to the summons, and it was he who had had his eye to the lens during the scene in the rose garden which had terminated in the ignominious expulsion of young Thurston at the hands of the infuriated duenna. When the recluse at last withdrew his gaze, his hands were clenched and he stood absolutely rigid in the tenseness of his indignation. He had seen Merle’s insultor ride toward the hills and Merle herself taken indoors under Tia Teresa’s protecting care. For almost a minute the storm of rage held him, then he relaxed and his look changed to one of terrible determination. He seized a rifle that was hanging on one of the walls and swiftly departed. At the arched gateway he spoke a few words to the two retainers on guard, and when he passed through the postern one of them, also equipped with a rifle, followed. Taking a cross-cut from the high road, together they descended the wooded hillside. In a little canyon just below the forest Dick Willoughby was rounding up a bunch of vagrant steers. He was alone, riding at a walking pace, driving a dozen or more beasts in front of him, and keeping an eye among the brushwood searching for more. On the roadway through the woods Marshall Thurston ambled along. He was a poor and awkward rider at all times, the discreetly-veiled jest of the nimble cowboys, to whom reins, saddle, and spurs were all as second nature. Now, when he imagined himself free from observation, he did not take pains to display even a semblance of horsemanship and, with bridle dropped, steadied himself by a grip on the saddle horn. In her bedroom Merle had soon recovered from her distress of mind. Dashing the tears from her eyes, she had enjoined Tia Teresa to say nothing to anyone about the unpleasant incident. Mrs. Darlington would be angered and would certainly tell Mr. Robles, while if the story ever reached Dick’s ears there could be no saying what further trouble might not ensue—a horse-whipping at least, with jeopardy to Dick’s position at the rancho and embitterment of an already dangerous quarrel. So Tia Teresa, to complete the comforting process, had assented to secrecy.
