"Mary," he exclaimed, "we shall fight, you and I, but we shall reign together. By God, you are my sister! Not just by coincidence of birth, but by the deeper kinship of our two souls. Great heavens, girl, since I came here to fight and to win, I've been lonely. It's not egotism but truth that makes me say this. I have been a conqueror--and all conquerors are lonely. You are mistress here. Do as you wish." He went back to the safe, but he looked up and laughed in a naive and winning fashion that was quite irresistible. "By the way," he suggested, "are you going to do me the honor to breakfast with me hereafter?" The girl laughed, too, and her eyes were as serenely gracious as a queen's may afford to be when, of her own will, she makes a royal concession. "Yes, I shall breakfast with you, _mon cher_ brother," she replied. Then she added with perfect mimicry of his own overbearing voice, "It's a trifle whether I breakfast in bed or not. It is vital that you remember who is mistress of this house. _C'est moi!_" A moment later, the man whose frown carried punishment for his adversaries and whose smile was so frank and winning for his friends, stood before his sister, watching her eyes as eagerly as a schoolboy while he opened the satin case and held out to her the string of pearls. "Mary," he said simply, "I'm not a man that curries favor with women. Paul looks after that gentle art for this family. You are the only girl I care about. When I give presents to a woman, it will be to you. There is no other woman in New York who could wear that rope of pearls and not look as if the pearls were wearing her. On your throat they are what jewels should always be--a subordinate decoration; partly eclipsed stars. I thought you might like them." She took the gift and raised it to the light, while her eyes kindled and her lips parted in delight, and as she looked at the pearls, her brother looked at her. "They are beautiful, aren't they?" she exclaimed and as she gazed at their well-matched perfection a glow kindled in her cheeks. "With such gifts," she murmured softly, "you could buy the souls of many women, _mon cher_. If you insist on being a master, at least, you are a generous one." Possibly at that moment, back of her delight, there rose a little ghost-like doubt. He had said, "We shall fight--but we shall reign together." She wondered vaguely how complete would be her participation in that reign. So far as they had fought, each had won a victory and he had paid a handsome indemnity--in future how would it be? Then he took the thing from her and fastened it around her neck and led her very gently to one of the great mirrors, standing at her shoulder and gazing at her through the glass. "So," she exclaimed, turning and laying her hands on his shoulders while her eyes twinkled with merriment, "they tell me that you compel men to wear your collar. Already, I, too, am wearing it."
