Sylvia had taken a hesitating step toward them, but halted, turning irresolutely; and suddenly over her crept a sensation of isolation--something of that feeling which had roused her at midnight from her bed and driven her to Grace Ferrall for a refuge from she knew not what.
The rustle of her silken dinner gown was scarcely perceptible as she turned. Siward, moving his head slightly, glanced up, then brought his sketch to a brilliant finish.
"Don't you think something of this sort is practicable?" he asked pleasantly, including Mrs. Ferrall and Katharyn Tassel in a general appeal which brought them into the circle of two. Grace Ferrall leaned forward, looking over Marion's shoulder, and Siward rose and stepped back, with a quick glance into the hall--in time to catch a glimmer of pale blue and lace on the stairs.
"I suppose my cigarettes are in my room as usual," he said aloud to himself, wheeling so that he could not have time to see Marion's offer of her little gold-encrusted case, or notice her quickly raised eyes, bright with suspicion and vexation. For she, too, had observed Sylvia's distant entrance, had been perfectly aware of Siward's cognizance of Sylvia's retreat; and when Siward went on sketching she had been content. Now she could not tell whether he had deliberately and skillfully taken his congé to follow Sylvia, or whether, in his quest for his cigarettes, chance might meddle, as usual. Even if he returned, she could not know with certainty how much of a part hazard had played on the landing above, where she already heard the distant sounds of Sylvia's voice mingling with Siward's, then a light footfall or two, and silence.
He had greeted her in his usual careless, happy fashion, just as she had reached her chamber door; and she turned at the sound of his voice, confused, unsmiling, a little pale.
"Is it headache, or are you too in quest of cigarettes?" he asked, as he stopped in passing her where she stood, one slender hand on the knob of her door.
"I don't smoke, you know," she said, looking up at him with a cool little laugh. "It isn't headache either. I was--boring myself, Mr. Siward."
"Is there any virtue in me as a remedy?"
"Oh, I have no doubt you have lots of virtues. … Perhaps you might do as a temporary remedy--first aid to the injured." She laughed again, uncertainly. "But you are on a quest for cigarettes."
"And you?"
"A rendezvous--with the Sand-Man. … Good night."
"Good night … if you must say it."
"It's polite to say something … isn't it?"
"It would be polite to say, 'With pleasure, Mr. Siward!'"
