He kissed his aunt on the cheek. “Your ladyship is looking charmingly.” He gave his hand to Horace. Horace took it, and passed on to Mercy. They walked away together slowly to the other end of the room. Julian seized on the chance which left him free to speak privately to his aunt. “I came in through the conservatory,” he said. “And I found that young lady in the room. Who is she?” “Are you very much interested in her?” asked Lady Janet, in her gravely ironical way. Julian answered in one expressive word. “Indescribably!” Lady Janet called to Mercy to join her. “My dear,” she said, “let me formally present my nephew to you. Julian, this is Miss Grace Roseberry--” She suddenly checked herself. The instant she pronounced the name, Julian started as if it was a surprise to him. “What is it?” she asked, sharply. “Nothing,” he answered, bowing to Mercy, with a marked absence of his former ease of manner. She returned the courtesy a little restrainedly on her side. She, too, had seen him start when Lady Janet mentioned the name by which she was known. The start meant something. What could it be? Why did he turn aside, after bowing to her, and address himself to Horace, with an absent look in his face, as if his thoughts were far away from his words? A complete change had come over him; and it dated from the moment when his aunt had pronounced the name that was not _her_ name---the name that she had stolen! Lady Janet claimed Julian’s attention, and left Horace free to return to Mercy. “Your room is ready for you,” she said. “You will stay here, of course?” Julian accepted the invitation---still with the air of a man whose mind was preoccupied. Instead of looking at his aunt when he made his reply, he looked round at Mercy with a troubled curiosity in his face, very strange to see. Lady Janet tapped him impatiently on the shoulder. “I expect people to look at me when people speak to me,” she said. “What are you staring at my adopted daughter for?” “Your adopted daughter?” Julian repeated--looking at his aunt this time, and looking very earnestly. “Certainly! As Colonel Roseberry’s daughter, she is connected with me by marriage already. Did you think I had picked up a foundling?” Julian’s face cleared; he looked relieved. “I had forgotten the Colonel,” he answered. “Of course the young lady is related to us, as you say.” “Charmed, I am sure, to have satisfied you that Grace is not an impostor,” said Lady Janet, with satirical humility. She took Julian’s arm and drew him out of hearing of Horace and Mercy. “About that letter of yours?” she proceeded. “There is one line in it that rouses my curiosity. Who is the mysterious ‘lady’ whom you wish to present to me?” Julian started, and changed color. “I can’t tell you now,” he said, in a whisper. “Why not?” To Lady Janet’s unutterable astonishment, instead of replying, Julian looked round at her adopted daughter once more.
