There was an instant of breathless suspense as she noiselessly turned the knob. It yielded to her touch, and she stole into the kitchen and up the back stairs like an unsubstantial shadow of the night, rather than a very tired and sore-hearted girl. Once in her room she sat down on her bed to think things over. She dared not move about for fear of being heard by Marjorie or her mother. Long she sat, moodily reviewing the year that had promised so much, yet had yielded her nothing but dissension and sorrow. One bare, ugly fact confronted her, looming up like a hideous monster whose dreadful claws had shredded her peace of mind and now waved at her the tattered fragments. It had all been her fault. For the first time she saw herself as she really was. A jealous, suspicious, hateful girl. It was she, not Marjorie, who had been unfaithful to friendship. But she had gone on blindly, unreasoningly, preferring to think the worst, until now it was too late to bridge the gap that she had daily widened between herself and her chum by her absurd jealousy. She could never regain her lost ground. She felt that Marjorie's patience with her had long since been exhausted. She dared not, could not, plead for reinstatement. All that remained to be done was to go through the rest of that dreadful year alone. When she and Marjorie had finished their sophomore course she would go quietly away, and they would, perhaps, never meet again. Alone with her bitter remorse, Mary wept until she could cry no more. As is usually the case with youth, she was sweeping in her self-condemnation. But that bitter hour of self-revelation did more to arouse within her the determination to conquer herself and establish the foundation for a noble womanhood than she could possibly believe. At last she pulled herself together to play the final scene in her evening's drama. Mrs. Dean had given her a latchkey, in order that she might let herself into the house, should she return from the party after the Deans had retired. At half-past ten o'clock she heard Marjorie and her mother come up the stairs to their rooms. Mr. Dean was away from home on a business trip. When all sounds of conversation between the two women had ceased and the house had apparently settled down for the night, Mary crept softly out of her room and down the stairs. Opening the hall door with stealthy fingers, she stepped into the vestibule. She listened intently for a sign from above that her soft-footed journey down the stairs had been discovered. But none came. Turning deliberately about, she retraced her steps, closing the hall door with sufficient force to announce her arrival. Without attempt at stealth she walked across the hall, up the stairs and into the pretty blue room that she had lately left. The closing of her own door purposely sounded her home coming. "Is that you, Mary?" called Marjorie's voice from the next room.
