And with a little bow she moved away with an air of composure which left her instructress stunned. She could scarcely recover her equilibrium sufficiently to greet her brother decently when he reached her side. She had never been so thoroughly at sea in her life. After she had gone to her room that night, her brother came and knocked at the door. When she opened it and let him in he walked to a chair and threw himself into it, wearing a rather excited look. "Olivia," he began at once, "what a bewildering girl!" Olivia sat down opposite to him, with a composed smile. "Miss Rogers, of course?" she said. "Of course," he echoed. And then, after a pause of two or three seconds, he added, in the tone he had used before: "What a delightfully mysterious girl!" "Mysterious!" repeated Olivia. "There is no other word for it! She has such an adorable face, she looks so young, and she says so little." And then, with serious delight, he added: "It is a new type!" Olivia began to laugh. "Why are you laughing?" he demanded. "Because I was so sure you would say that," she answered. "I was waiting for it." "But it is true," he replied, quite vehemently. "I never saw anything like her before. I look at her great soft eyes and I catch glimpses of expression which don't seem to belong to the rest of her. When I see her eyes I could fancy for a moment that she had been brought up in a convent or had lived a very simple, isolated life, but when she speaks and moves I am bewildered. I want to hear her talk, but she says so little. She does not even dance. I suppose her relatives are serious people. I dare say you have not heard much of them from her. Her reserve is so extraordinary in a girl. I wonder how old she is?" "Nineteen, I think." "I thought so. I never saw anything prettier than her quiet way when I asked her to dance with me. She said, simply, 'I do not dance. I have never learned.' It was as if she had never thought of it as being an unusual thing." He talked of her all the time he remained in the room. Olivia had never seen him so interested before. "The fascination is that she seems to be two creatures at once," he said. "And one of them is stronger than the other and will break out and reveal itself one day. I begin by feeling I do not understand her, and that is the most interesting of all beginnings, I long to discover which of the two creatures is the real one." When he was going away he stopped suddenly to say: "How was it you never mentioned her in your letters? I can't understand that." "I wanted you to see her for yourself," Olivia answered. "I thought I would wait." "Well," he said, after thinking a moment, "I am glad, after all, that you did." CHAPTER V. "I HAVE HURT YOU."
