She watched him curiously, not his hands, now, but his lean, intent face, striving to penetrate that masculine mask, trying to understand. Varying and odd reflections and emotions possessed her in turn, and passedwonder, bewilderment at herself, at him; a slight sense of fear, then a brief and sudden access of shyness, succeeded by the by glow of an emotion new and strange and deep. And this, in turn, by vague bewilderment again, in which there was both a hint of fear, and a tinge of something exquisite. Within herself she was dimly conscious that a certain gaiety, an irresponsibility and lightness had died out in her, perhaps permanently, yet leaving no void. What it was that replaced these she could not nameshe only was conscious that if these had been subdued by a newer knowledge, with a newer seriousness, this unaccustomed gravity had left her heart no less tender, and had deepened her capacity for emotion to depths as profound and unexplored as the sudden mystery of their discovery by herself. Always, now, while she posed, she was looking at him with a still intentness, as though he really wore a mask and she, breathlessly vigilant, watched for the moment when he might forget and lift it. But during the weeks that followed, if the mask were indeed only the steady preoccupation that his visage wore, she seemed to learn nothing more about him when his features lost their dark absorption and he caught her eye and smiled. No, the smile revealed nothing except another mask under the more serious cast of concentrationonly another disguise that covered whatever this man might truly be deeper downthis masculine and unknown invader of frontiers surrendered ere she had understood they were even besieged. And during these weeks in early spring their characteristics, even characters, seemed to have shifted curiously and become reversed; his was now the light, irresponsible, half-mocking badinagealmost boyishly boisterous at times, as, for instance, when he stepped forward after the pose and swung her laughingly from the model-platform to her corner on the sofa.
