Swift as light the glowing mirror disappeared, and then, as if through a window opened in the air before his eyes, Victor perceived a strange face confronting him, the face of a girl with deep and tender eyes, incredibly beautiful. Her eyes were in shadow, but the pure oval of her cheeks, the dainty grace of her chin, the broad, full brow and something ineffably pure in the faintly happy smile, stopped his breath with awe. He forgot his mother, his problems, his doubts, in study of the unearthly beauty of this vision. Mrs. Joyce whispered in ecstasy, "It is Altair!" The angelic lips parted, and a low voice, so gentle it was like the murmur of a leaf, replied, "_Yes, it is Altair._" And to Victor her voice was of exquisite delicacy. "_Believe, be faithful._" No one breathed. It was as if they had been permitted to gaze upon one of heaven's angelic choir. How came she there? Who was she? Before these questions could be framed she disappeared, silently as a bubble on the water, leaving behind only that delicious, subtle, unaccountable odor as of tropic fruits and unknown flowers. Leo, breathing a sigh of sad ecstasy, exclaimed: "Is she not beautiful? Never has she shown herself more glorious than to-night." Victor was like one drugged and dreaming. There was no question of his mother's honesty in his mind. He did not relate the vision to her, and he winced with pain as Leo spoke. He wished to recall the face, to hear that whisper again. The effect upon him was enormous, instant, unfolding. In all his life nothing mystic, nothing to disturb or rouse his imagination had hitherto come to him, and now this transcendent marvel, this face born of the invisible and intangible essence of the air, beat down his self-assurance and destroyed his smug conception of the universe. He lost sight of his hypothesis and accepted Altair for what she seemed, a gloriously beautiful soul of another world, a world of purity and light and love. He remained silent as Mrs. Joyce rose and went to his mother. He was still in his seat when they turned up the lights. Leo spoke to him, but he did not answer. Strange transformation! At the moment her voice jarred upon him. She seemed commonplace, prosaic, in contrast with the woman who had looked upon him from the luminous shadow. Gradually the walls he hated, the entangling relationship he feared, returned upon him; and though he realized something of the revealing character of his reticence, he had not the will to break it. He watched his mother return to her normal self with such detachment that she at last became aware of it and lifted her feeble hands in search of him. "Victor, come to me!" she pleaded. He went to her then, still in a daze, and to her question, "Did your father come?" he replied, brokenly, "A voice came, but I can't talk about that now--I must go out into the air."
