What it was she could not do, remained an impenetrable mystery to Sylvia, for at that moment she turned away quickly, and went back up the driveway, her face in her hands. Sylvia hesitated, penetrated, in spite of her absorption in her own affairs, by a vague pity, but hearing in the distance the clang of the trolley-car's bell, she herself turned and ran desperately down the driveway. She reached the public road just in time to stop the heavy car, and to swing herself lightly on, to all appearances merely a rather unusually well-set-up, fashionably dressed young lady, presenting to the heterogeneous indifference of the other passengers in the car even a more ostentatiously abstracted air than is the accepted attitude for young ladies traveling alone. One or two of her fellow voyagers wondered at the deep flush on her face, but forgot it the next moment. It was a stain which was not entirely to fade from Sylvia's face and body for many days to come. CHAPTER XX "BLOW, WIND; SWELL, BILLOW; AND SWIM, BARK!" She reached home, as she had thought, before ten o'clock, her unexpected arrival occasioning the usual flurry of exclamation and question not to be suppressed even by the most self-contained family with a fixed desire to let its members alone, and a firm tradition of not interfering in their private affairs. Judith had come home before her father and now looked up from her game of checkers with wondering eyes. Sylvia explained that she was not sick, and that nothing had happened to break up or disturb the house-party. "I just _felt_ like coming home, that's all!" she said irritably, touched on the raw by the friendly loving eyes and voices about her. She was glad at least that her father was not at home. That was one less to look at her. "Well, get along to bed with you!" said her mother, in answer to her impatient explanation. "And, you children--keep still! Don't bother her!" Sylvia crept upstairs into the whiteness of her own slant-ceilinged room, and without lighting a lamp sat down on the bed. Her knees shook under her. She made no move to take off her furs or hat. She felt no emotion, only a leaden fatigue and lameness as though she had been beaten. Her mother, coming in five minutes later with a lighted lamp and a cup of hot chocolate, made no comment at finding her still sitting, fully dressed in the dark. She set the lamp down, and with swift deftness slipped out hatpins, unhooked furs, unbuttoned and unlaced and loosened, until Sylvia woke from her lethargy and quickly completed the process, slipping on her nightgown and getting into bed. Not a word had been exchanged. Mrs. Marshall brought the cup of hot chocolate and Sylvia drank it as though she were a little girl again. Her mother kissed her good-night, drew the blankets a little more snugly over her, opened two windows wide, took away the lamp, and shut the door.
