In the midst of one of her animated sentences, a low moan was heard from the inner room. "Excuse me," said Astra hurriedly, amazed to see how completely she had forgotten her cares, fears, and griefs, in the magic of the stranger's presence,—"Excuse me, I must go to my mother."
Mrs. Lyte had waked, as was too often the case, in a spasm of pain. Astra hastened to call Cathie from the kitchen to assist the laboring breath with gentle wafts of air from a fan, while she herself measured some drops of a soothing mixture, and lifted her mother's head on her arm, to enable her to swallow and to breathe more easily. Several anxious moments had passed thus, in silence broken only by the painful respirations of the invalid, when a low, sweet strain of melody stole so gently into the room that Astra could not tell, at first, from whence it came. So soft was it that it melted into the ear without making any apparent demand upon the attention, yet so clear that not one liquid note was lost. The swollen veins of Mrs. Lyte's forehead subsided; her chest ceased its agonized heaving; a peaceful, happy smile broke over her face.
"What is it?" she asked, wonderingly, when the strain ended,—not abruptly, but gradually growing fainter, until it was impossible to tell just at what point sound became silence.
Astra whispered softly that she had left a strange visitor in the studio, who appeared to be singing unconsciously to herself.
"If she would only sing again!" murmured Mrs. Lyte, wistfully.
With her usual impulsiveness, Cathie rushed to the studio door. "Mamma wishes you would sing—" she began, and then stopped short, no less surprised and fascinated by the face that met her gaze than her sister had been.
The stranger reflected for a moment, then her voice again pervaded the air, as with the very soul of restful melody. As she sang, the child moved slowly toward her, drawn as irresistibly as the magnet to the loadstone, till she stood close to her side, encircled by her arm, and gazing at her with round, wondering eyes. As the song ceased, she slid her hand half-curiously, half-timidly over her shoulder.
"Have you wings?" she asked, earnestly. "Did you fly down?"
Before the visitor could reply, except by a swift expression of something like pain that flitted across her face, Astra appeared in the doorway.
"Mother wishes to see you, and thank you," she said. "Will you step this way?"
