The two stopped often, apparently in argument, as though one would proceed in the direction that they were going while the other demurred. But each time the smaller won reluctant consent from the other, and so they came closer and closer to the last line of workers toiling between the enclosure from which they had come and the hill where Gahan of Gathol lay watching, and then suddenly the smaller figure struck its companion full in the face. Gahan, horrified, saw the latter's head topple from its body, saw the body stagger and fall to the ground. The man half rose from his concealment the better to view the happening in the valley below. The creature that had felled its companion was dashing madly in the direction of the hill upon which he was hidden, it dodged one of the workers that sought to seize it. Gahan hoped that it would gain its liberty, why he did not know other than at closer range it had every appearance of being a creature of his own race. Then he saw it stumble and go down and instantly its pursuers were upon it. Then it was that Gahan's eyes chanced to return to the figure of the creature the fugitive had felled. What horror was this that he was witnessing? Or were his eyes playing some ghastly joke upon him? No, impossible though it was--it was true--the head was moving slowly to the fallen body. It placed itself upon the shoulders, the body rose, and the creature, seemingly as good as new, ran quickly to where its fellows were dragging the hapless captive to its feet. The watcher saw the creature take its prisoner by the arm and lead it back to the enclosure, and even across the distance that separated them from him he could note dejection and utter hopelessness in the bearing of the prisoner, and, too, he was half convinced that it was a woman, perhaps a red Martian of his own race. Could he be sure that this was true he must make some effort to rescue her even though the customs of his strange world required it only in case she was of his own country; but he was not sure; she might not be a red Martian at all, or, if she were, it was as possible that she sprang from an enemy people as not. His first duty was to return to his own people with as little personal risk as possible, and though the thought of adventure stirred his blood he put the temptation aside with a sigh and turned away from the peaceful and beautiful valley that he longed to enter, for it was his intention to skirt its eastern edge and continue his search for Gathol beyond.
