Instantly, as her hand came in contact with the mask on her face, she realized that it was only her own reflection in the glass which had frightened her, but the shock was so great she could not stop trembling.
Wakened by the sound of the breaking pitcher and Mary's wild plunge back into bed, Joyce sat up in alarm, but in response to her whisper Mary explained in muffled tones from under the bedclothes that she had simply gotten up for a drink of water and dropped the pitcher.

All the rest of the night her sleep was fitful and uneasy, for toward morning her face began to burn as if it were on fire.

She tore off the mask and used it to wipe away what remained of the ointment.

Most of it had been absorbed, however, and the skin was broken out in little red blisters.
Maybe in her zeal she had used too much of the magical cosmetic, or maybe her face, already made tender by various applications, resented the vigorous rubbings she gave it.

At any rate she had cause to be frightened when she saw herself in the mirror.
