He scarcely returned the slight salute given by Gardley, and the two young people touched up their horses and were soon out of sight in the mesquite. But something in the frightened look of the girl's eyes caused Gardley to turn and look after the two. Where could they be going at that hour of the evening? It was not a trail usually chosen for rides. It was lonely and unfrequented, and led out of the way of travelers. Gardley himself had been a far errand for Jasper Kemp, and had taken this short trail back because it cut off several miles and he was weary. Also, he was anxious to stop in Ashland and leave Mom Wallis's request that Margaret would spend the next Sabbath at the camp and see the new curtains. He was thinking what he should say to her when he saw her in a little while now, and this interruption to his thoughts was unwelcome. Nevertheless, he could not get away from that frightened look in the girl's eyes. Where could they have been going? That fellow was a new-comer in the region; perhaps he had lost his way. Perhaps he did not know that the road he was taking the girl led into a region of outlaws, and that the only habitation along the way was a cabin belonging to an old woman of weird reputation, where wild orgies were sometimes celebrated, and where men went who loved darkness rather than light, because their deeds were evil. Twice Gardley turned in his saddle and scanned the desert. The sky was darkening, and one or two pale stars were impatiently shadowing forth their presence. And now he could see the two riders again. They had come up out of the mesquite to the top of the mesa, and were outlined against the sky sharply. They were still on the trail to old Ouida's cabin! With a quick jerk Gardley reined in his horse and wheeled about, watching the riders for a moment; and then, setting spurs to his beast, he was off down the trail after them on one of his wild, reckless rides. Down through the mesquite he plunged, through the darkening grove, out, and up to the top of the mesa. He had lost sight of his quarry for the time, but now he could see them again riding more slowly in the valley below, their horses close together, and even as he watched the sky took on its wide night look and the stars blazed forth. Suddenly Gardley turned sharply from the trail and made a detour through a grove of trees, riding with reckless speed, his head down to escape low branches; and in a minute or two he came with unerring instinct back to the trail some distance ahead of Forsythe and Rosa. Then he wheeled his horse and stopped stock-still, awaiting their coming. By this time the great full moon was risen and, strangely enough, was at Gardley's back, making a silhouette of man and horse as the two riders came on toward him.
