In answer to her call a dozen guardsmen came racing across the scarlet sward, their gleaming long-swords naked in the sun, the metal of their accoutrements clanking against that of their leathern harness, and in their throats hoarse shouts of rage at the sight which met their eyes. But before they had passed half across the royal garden to where Astok of Dusar still held the struggling girl in his grasp, another figure sprang from a cluster of dense foliage that half hid a golden fountain close at hand. A tall, straight youth he was, with black hair and keen grey eyes; broad of shoulder and narrow of hip; a clean-limbed fighting man. His skin was but faintly tinged with the copper colour that marks the red men of Mars from the other races of the dying planet—he was like them, and yet there was a subtle difference greater even than that which lay in his lighter skin and his grey eyes. There was a difference, too, in his movements. He came on in great leaps that carried him so swiftly over the ground that the speed of the guardsmen was as nothing by comparison. Astok still clutched Thuvia’s wrist as the young warrior confronted him. The new-comer wasted no time and he spoke but a single word. “Calot!” he snapped, and then his clenched fist landed beneath the other’s chin, lifting him high into the air and depositing him in a crumpled heap within the centre of the pimalia bush beside the ersite bench. Her champion turned toward the girl. “Kaor, Thuvia of Ptarth!” he cried. “It seems that fate timed my visit well.” “Kaor, Carthoris of Helium!” the princess returned the young man’s greeting, “and what less could one expect of the son of such a sire?” He bowed his acknowledgment of the compliment to his father, John Carter, Warlord of Mars. And then the guardsmen, panting from their charge, came up just as the Prince of Dusar, bleeding at the mouth, and with drawn sword, crawled from the entanglement of the pimalia. Astok would have leaped to mortal combat with the son of Dejah Thoris, but the guardsmen pressed about him, preventing, though it was clearly evident that naught would have better pleased Carthoris of Helium. “But say the word, Thuvia of Ptarth,” he begged, “and naught will give me greater pleasure than meting to this fellow the punishment he has earned.” “It cannot be, Carthoris,” she replied. “Even though he has forfeited all claim upon my consideration, yet is he the guest of the jeddak, my father, and to him alone may he account for the unpardonable act he has committed.” “As you say, Thuvia,” replied the Heliumite. “But afterward he shall account to Carthoris, Prince of Helium, for this affront to the daughter of my father’s friend.” As he spoke, though, there burned in his eyes a fire that proclaimed a nearer, dearer cause for his championship of this glorious daughter of Barsoom.
