"Oh, no, no!" she said, quickly, and with a touch of colour. "I am not at all curious. I mean," she explained, "that knowing his name would not increase my interest in him; quite the reverse. You know what I mean? But I fancy I am interested in him because I think he may be in trouble. You see, when one has suffered oneself——"

"Yes, that is the way with you women," said the old man. "In fact, I suppose that, until you have suffered, you do not become women." He glanced at the sheets of paper which lay on the little writing-desk and added, "I am afraid I am keeping you from your work. It was very kind of you to ask me to stay to tea—and to tell me what you have told me. I wish I could help you——. But, no, I don't; for, if I could be of any assistance to you, you would not let me; you are too proud, Miss Grant. I like you all the better for the fact."

"Oh, but you have helped me, more than you know," Celia said, quickly. "You don't know what a delight it is to me to hear the violin you play so beautifully; but, of course, you are an artist."

"Thank you," he said, his voice almost inaudible, and yet with that peculiar vibrance in it. "I was afraid I worried you."

"No, no," said Celia; "I am always sorry when you leave off. You play me to sleep sometimes and—and keep me from brooding. Not that I have any cause to brood," she added, quickly; "for I count myself lucky."

"Yes," he said; "you are lucky; for you have youth, beauty—I beg your pardon," he apologized with a little bow and a gesture which were strangely courtly. "And best of all, you have hope; without that, one is indeed unfortunate."

He rose, and Celia accompanied him to the door; it was only a few steps distant; but the old man moved towards it as if he had been accustomed to traversing apartments of a larger size. As Celia opened the door, the one opposite hers opened at the same moment, and a lady came out. Judging by her figure, for her face was thickly veiled, she was young; she was plainly but richly dressed, and wore a coat and muff of sable. Her appearance was so strangely different from that of the residents and visitors of the Buildings that Celia could not help staring at her with surprise. As if she were conscious of, and resented, Celia's intent regard, the lady turned her head away, and, keeping as near the wall as possible, descended the stairs quickly.

Celia and Mr. Clendon neither exchanged glances nor made any remark. With a gesture of farewell and thanks, he went down. Half-unconsciously, she stood looking at the door which the lady had closed after her; then Celia shut hers and went back to clearing away the tea.

When Mr. Clendon had asked her if she had fitted a history to the young man who had interested her so much, she had replied in the negative; but now, involuntarily, she began to do so. Of course, he was in trouble; probably in debt; this beautifully-dressed woman was his sister, or, perhaps, his sweetheart; she had come to help him, to comfort him. Something in the idea was pleasant and welcome to Celia; he was such a good-looking young fellow; that voice of his, which used to sing but had become silent lately, had a good, true ring in it; yes, it was nice to think that his sister—or his sweetheart—had come to bring him comfort.

She sat down to her notes; but she could not concentrate herself upon her work. The imaginary history of the young man obtruded upon her; she decided that she would go out for a walk, and take up her work again when she returned. She was getting her coat and hat when Mr. Clendon began to play; she changed her mind about the walk and went to the door to open it an inch or so, that she might hear more distinctly the soft strains of the Beethoven Sonata which came floating up to her. As she opened the door, she heard a strange sound rising above the notes of the music; it was that, perhaps, most terrible of all sounds, the unbidden, irresistible groan, rising from a man's tortured heart; and it came from the young man's room.
