To the Waldo of a few months previous it would not have been visible, but the new woodcraft of the man scented the abnormal in the vague suggestion of movement out among the long-waving grasses of the plain. And now, with every sense alert and riveted upon the spot, he was quick to perceive that it was an animal moving slowly toward the cliffs at the upper end of the valley. Presently a little rise of ground, less thickly grassed, brought the creature into full view for an instant; but in that instant Waldo saw that the thing he watched was a woman. As he turned to hurry after her he saw Flatfoot top another hill a half mile nearer than he had before been, and as the cave man came into view he turned his eyes in the direction that Waldo had been looking. A second later and he had abandoned the pursuit of Waldo and was running rapidly toward the woman. Nadara had apparently circled back once more, this time from the sea, and coming up the valley had passed Waldo and come opposite Flatfoot before either of them had discovered her. The young man gave a little cry of alarm as he realized that the cave man was nearer to the girl than he--by a good half mile, he judged, and so he put every ounce of his speed into the wild dash he made down the hill into a gully which led out upon the valley. On and on he raced unable to see either Flatfoot or Nadara; hoping, ever hoping, that he would be the first to win to her side; for Nadara had told him of the atrocities that such a creature as Flatfoot might perpetrate upon a woman rather than permit her to escape him or fall into the hands of another. Nadara, being up wind, caught neither the scent nor noise of the two who were racing madly toward her. The first knowledge she had that she was not alone in the valley was the sight of Flatfoot as he broke suddenly through a clump of tall grass not fifty paces from her. She gave a little scream and started to run; but she was very tired from the days of unremitting flight which had so sorely taxed her endurance, and thus it was no wonder that she slipped and fell before she had taken a dozen steps. Scarcely had she gained her feet when Flatfoot was upon her, one hand grasping her by the arm. "Come with me in peace or I will kill you!" he cried. "Kill me, then," retorted the despairing girl, "for I shall never come with you; first will I kill myself." Flatfoot did not wish to kill her, nor did he wish her to escape, as she would be very likely to do should he be interrupted by the fellow who must even now be quite close to them. Possibly if he could keep the girl quiet they might hide in the grass until their pursuer had gone by, and so Flatfoot, acting upon the idea, clapped a rough hand over Nadara's mouth and dragged her back along the trail he had just made. The girl struggled--striking and clawing at the hairy brute that pulled her along at his side--but she was as helpless in his clutches as if she had been a day-old babe.
