He seemed to have been riding for days when he caught sight of something moving over a ridge far ahead of him and he closed his eyes in hope that the momentary rest would clear his vision. After awhile he saw it push up over another low ridge and he knew it to be a horseman riding in the same direction as himself. Again he closed his eyes and unmercifully quirted the tired and unwilling horse into a pace it could not hold for long. Another look ahead showed him that the horseman was a Mexican, which meant that he was hardly a foe even if not a friend. And he sneered as he thought how little it mattered whether the Mexican was an enemy or not, for one enemy ahead and a Greaser at that was greatly to be preferred to those who might be following him. Soon he frowned in slowly dawning recognition. It was Miguel and he had obtained quite a start. Conjecturing about how he had managed to be so far in the lead stirred up again the vague suspicions which had been intruding themselves upon him while he had been unable to think clearly; but he was thinking clearly now, he told himself, and his eyes glinted the sudden anger. He thought he now knew why the town had been entered so easily, why they had been allowed to penetrate unopposed to its center. It was plain enough why they had been permitted to get within a few feet of Quayle's back door, and then be stopped with a volley at a murderously short range. As he reviewed it he almost was stunned by the thought of his own escape and he tried to puzzle it out. It might be that every waiting puncher thought that others were covering him--and in this he was right. The compact group behind him had drawn every eye. It had been one of those freakish tricks of fate which might not occur again in a hundred fights; and it turned cold, practical Hugh Roberts into a slave of superstition. On the way to town he had sneered when Miguel had pointed out a chaparral cock which raced with them for several miles and claimed that it was an omen of good luck; but from this time on no "roadrunner" ever would hear the angry whine of his bullets. Thinking of Miguel brought him back to his suspicions and he looked at the distant rider with an expression on his face which would have caused chills to race up and down the Mexican's back, could he have seen them. Miguel, unhurt, riding leisurely back to the herd, with a head-start great enough to be in itself incriminating. And then the Mexican turned in his saddle and looked back, and Roberts let his horse fall into a saner pace.
