“I did not do it, Thuvia,” he said. “But let me be entirely honest with you. As much as I love your father, as much as I respect Kulan Tith, to whom you are betrothed, as well as I know the frightful consequences that must have followed such an act of mine, hurling into war, as it would, three of the greatest nations of Barsoom—yet, notwithstanding all this, I should not have hesitated to take you thus, Thuvia of Ptarth, had you even hinted that it would not have displeased _you_. “But you did nothing of the kind, and so I am here, not in my own service, but in yours, and in the service of the man to whom you are promised, to save you for him, if it lies within the power of man to do so,” he concluded, almost bitterly. Thuvia of Ptarth looked into his face for several moments. Her breast was rising and falling as though to some resistless emotion. She half took a step toward him. Her lips parted as though to speak—swiftly and impetuously. And then she conquered whatever had moved her. “The future acts of the Prince of Helium,” she said coldly, “must constitute the proof of his past honesty of purpose.” Carthoris was hurt by the girl’s tone, as much as by the doubt as to his integrity which her words implied. He had half hoped that she might hint that his love would be acceptable—certainly there was due him at least a little gratitude for his recent acts in her behalf; but the best he received was cold skepticism. The Prince of Helium shrugged his broad shoulders. The girl noted it, and the little smile that touched his lips, so that it became her turn to be hurt. Of course she had not meant to hurt him. He might have known that after what he had said she could not do anything to encourage him! But he need not have made his indifference quite so palpable. The men of Helium were noted for their gallantry—not for boorishness. Possibly it was the Earth blood that flowed in his veins. How could she know that the shrug was but Carthoris’ way of attempting, by physical effort, to cast blighting sorrow from his heart, or that the smile upon his lips was the fighting smile of his father with which the son gave outward evidence of the determination he had reached to submerge his own great love in his efforts to save Thuvia of Ptarth for another, because he believed that she loved this other! He reverted to his original question. “Where are we?” he asked. “I do not know.” “Nor I,” replied the girl. “Those who stole me from Ptarth spoke among themselves of Aaanthor, so that I thought it possible that the ancient city to which they took me was that famous ruin; but where we may be now I have no idea.”
