On these exploring expeditions he was frequently accompanied by Natasha and Radna and her husband. Sometimes Arnold would be enticed away from his chemicals, and his designs on the lives of his enemies, and after breakfasting soon after sunrise would go off for a long day's ramble to some unknown part of their wonderful domain, in which, like children in a fairyland, they were always discovering some new wonders and beauties. And, indeed, no children could have been happier or freer from care than they were during this delightful interval in the tragedy in which they were so soon to play such conspicuous parts. The two wedded lovers, with the dark past put far behind them for ever, found perfect happiness in each other's society, and so left, it is almost needless to add, Arnold and Natasha pretty much to their own devices. Indeed, Natasha had more than once declared that she would have to get the Princess to join the party, as Radna had proved herself a hopeless failure as a chaperone.
Every one in the valley by this time looked upon Arnold and Natasha as lovers, though their rank in the Brotherhood was so high that no one ventured to speak of them as betrothed save by implication. How Natas regarded them was known only to himself. He, of course, saw their intimacy, and since he said nothing he doubtless looked upon it with approval; but whether he regarded it as an intimacy of friends or of lovers, remained a mystery even to Natasha herself, for he never by any chance made an allusion to it.
As for Arnold, he had scrupulously observed the compact tacitly made between them on the first and only occasion that he had ever spoken words of love to her. They were the best of friends, the closest companions, and their intercourse with each other was absolutely frank and unrestrained, just as it would have been between two close friends of the same sex; but they understood each other perfectly, and by no word or deed did either cross the line that divides friendship from love.
She trusted him absolutely in all things, and he took this trust as a sacred pledge between them that until his part of their compact had been performed, love was a forbidden subject, not even to be approached.
So perfectly did Natasha play her part that though he spent hours and hours alone with her on their exploring expeditions, and in rowing and sailing on the lake, and though he spent many another hour in solitude, weighing her every word and action, he was utterly unable to truthfully congratulate himself on having made the slightest progress towards gaining that love without which, even if he held her to the compact in the day of victory, victory itself would be robbed of its crowning glory and dearest prize.
To a weaker man it would have been an impossible situation, this constant and familiar companionship with a girl whose wonderful beauty dazzled his eyes and fired his blood as he looked upon it, and whose winning charm of manner and grace of speech and action seemed to glorify her beauty until she seemed a being almost beyond the reach of merely human love—rather one of those daughters of men whom the sons of God looked upon in the early days of the world, and found so fair that they forsook heaven itself to woo them.
Trained and disciplined as he had been in the sternest of all schools, and strengthened as he was by the knowledge of the compact that existed between them, there were moments when his self-control was very sorely tried, moments when her hand would be clasped in his, or rested on his shoulder as he helped her across a stream or down some steep hillside, or when in the midst of some animated discussion she would stop short and face him, and suddenly confound his logic with a flash from her eyes and a smile on her lips that literally forced him to put forth a muscular effort to prevent himself from catching her in his arms and risking everything for just one kiss, one taste of the forbidden fruit within his reach, and yet parted from him by a sea of blood and flame that still lay between the world and that empire of peace which he had promised to win for her sweet sake.
Once, and once only, she had tried him almost too far. They had been discussing the possibility of ruling the world without the ultimate appeal to force, when the nations, weary at length of war, should have consented to disarm, and she, carried away by her own eloquent pleading for the ultimate triumph of peace and goodwill on earth, had laid her hand upon his arm, and was looking up at him with her lovely face aglow with the sweetest expression even he had ever seen upon it.
Their eyes met, and there was a sudden silence between them. The eloquent words died upon her lips, and a deep flush rose to her cheeks and then faded instantly away, leaving her pale and with a look almost of terror in her eyes. He took a quick step backwards, and, turning away as though he feared to look any longer upon her beauty, said in a low tone that trembled with the strength of his repressed passion—
"Natasha, for God's sake remember that I am only made of flesh and blood!"
