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.

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. Startled, chilled, by the sound, she wondered that she could hear it so plainly; then she saw that the door opposite was slightly ajar; evidently the visitor had failed to close it. Celia waited, with the familiar horror, the tense expectation, for a repetition of the groan. It came. Obeying an impulse, a womanly impulse, to fly to the call of such poignant distress, Celia
