Thus hatred rather than love had been the creed of her life and the mainspring of her actions, and, save her father and her one friend Radna, she stood aloof from mankind and its loves and friendships, rather the beautiful incarnation of an abstract principle than a woman, to whom love and motherhood were the highest aims of existence.
More than this, she was the daughter of a Jew, and therefore held herself absolutely at her father's disposal as far as marriage was concerned, and if he had given her in wedlock even to a Russian official, telling her that the Cause demanded the sacrifice, she would have obeyed, though her heart had broken in the same hour.
Although he had never hinted directly at such a thing, the conviction had been growing upon her for the last two or three years that Natas really intended her to marry Tremayne, and so, in the case of his own death, form a bond that should hold him to the Brotherhood when the chain of his own control was snapped. Though she instinctively shrank from such a union of mere policy, she would enter it without hesitation at her father's bidding, and for the sake of the Cause to which her life was devoted.
How great such a sacrifice would be, should it ever be asked of her, no one but herself could ever know, for she was perfectly well aware that in Tremayne's strange double life there were two loves, one of which, and that not the real and natural one, was hers.
Had she felt that she had the disposal of herself in her own hands, she would not, perhaps, have waited with such painful apprehension the avowal which hour after hour, now that they were brought into such close and constant relationships on board this little vessel high in mid-air, she saw trembling on the lips of her rescuer.
Arnold's life of hard, honest work, and his constant habit of facing truth in its most uncompromising forms, had made dissimulation almost impossible to him; and added to that, situated as he was, there was no necessity for it. Colston knew of his love, and the Princess had guessed it long ago. Did Natasha know his open secret? Of that he hardly dared to be sure, though something told him that the inevitable moment of knowledge was near at hand.
For the first twenty-four hours of the voyage he had seen very little of either her or the Princess, as they had mostly remained in their cabins, enjoying a complete rest after the terrible fatigue and suffering they had gone through since their capture in Moscow, but on the Thursday morning they had had breakfast in the saloon with him and Colston, and had afterwards spent a portion of the morning on deck, deeply interested in watching the fight between the British and Russians. Thanks to Radna's foresight, they had each found a trunk full of suitable clothing on board the Ariel. These had been taken to Drumcraig by Colston, and placed in the cabins intended for their use, and so they were able to discard the uncouth but useful costumes in which they had made their escape.
In the afternoon Arnold had had to perform the pleasant task of showing them over the Ariel, explaining the working of the machinery, and putting the wonderful vessel through various evolutions to show what she was capable of doing.
He rushed her at full speed through the air, took flying leaps over outlying spurs of mountain ranges that lay in their path, swooped down into valleys, and flew over level plains fifty yards from the ground, like an albatross over the surface of a smooth tropic sea. Then he soared up from the earth again, until the horizon widened out to vast extent, and they could see the mighty buttresses of "the Roof of the World" stretching out below them in an endless succession of ranges as far as the eye could reach.
Neither Natasha nor the Princess could find words to at all adequately express all that they saw and learnt during that day of wonders, and all night Natasha could hardly sleep for waking dreams of universal empire, and a world at peace equitably ruled by a power that had no need of aggression, because all the realms of earth and air belonged to those who wielded it.
