He looked from the cast to Ninitta. He had only seen her at the studio, and he experienced a faint feeling of surprise at detecting a subtle difference in her here at home. It was nothing so tangible that he could have told by what means he received the impression, yet it was sufficiently definite to make him lose something of the freedom with which he had always addressed her. She was no longer simply the model, she was an Italian woman in her own home. The years during which they had been separated had formed and strengthened Ninitta's character. If Herman had not before noted the alteration, it was due in part to his pre-occupation and in part to the force of old habit which made her manner toward him much the same as formerly. To-night he began to appreciate the change in her, and he felt the awkwardness which always results from the discovery that we must adapt ourselves to a modified condition in a friend. On her side Ninitta was naturally surprised at seeing the sculptor. She had come to regard as hopeless all speculations upon his intentions, and she had waited patiently until he should choose to show her favor, tacitly acknowledging his right to do whatever should be his good pleasure. Had he come at any time and said, "Ninitta, I am here to marry you," she would gladly but quietly have made ready to follow where he chose to lead, even to the world's end. Equally, had he said, "Ninitta, I have come to say good-by; you will never see me again," she would have acquiesced without a murmur, and then, perhaps, have taken her own life. As long as it was his simple wish, uninfluenced by the will of another, she would never have questioned. Now, however, all passive acquiescence was at an end. Since the scene in Helen's studio, Ninitta had an object upon which to expend all her energies, and she even almost forgot to love Herman in the intensity of her sudden jealous hatred of Mrs. Greyson. Yesterday Grant Herman would have found a woman not unlike the Ninitta of old times, tender, loving, pathetically submissive; today he was confronted by a fury, only restrained by the respect for his presence born of long habit. "Good evening!" he said gently, as he entered, his mood softened by the struggle through which he had passed in his studio. "Good evening!" she answered defiantly, in Italian. "So you are not with her!" "What!" he exclaimed. He had been wholly unprepared for this outburst, and for the instant was too surprised to at all understand it. A sudden rage seemed to seize Ninitta, which swept away all barriers of restraint. "_Si_, _si_, _si_," she cried, "I am not blind! What if you are my betrothed, when this woman comes to entrap you, to bewitch you with an evil eye, to steal your soul! Yes, yes; you are not with her to-night as you were last night. Did I not see you myself come out of her house?" "Stop!" he said in his most commanding tone, but without anger.
