She rocked backward and forward, a prey to remorse.

With a cry of sudden terror, Sister Catalina flung the crumpled photograph from her. It fluttered like a blown leaf, was caught by a vagrant breeze and wafted toward Sister Teresa, crouching by the gate. As if the white-hot fires of the dreaded volcano had suddenly poured toward her in searing streams, she screamed aloud, dragged herself to her feet with surprising alacrity, and rushed for protection to her former assailant, throwing her arms about Sister Catalina in a paroxysm of fear.

“Ay, cry aloud your terror, sisters,” continued Sister Eulalia. “What was this thing of mystery the Fiend brought among ye? In the winking of an eye it brought strife and anger. How wise were they who forbade us looking-glasses. For ye forgot your own images till ye knew them no more. Behold, this thing that showed ye yourselves, as in a glass that was not glass, let in the very spirit of the devil. All the years of our happiness together in God were as nothing before the magic of the Evil One, whom we welcomed. Though we were warned, though we knew him the ‘Prince of Disguise’! Pray for pardon—pray quickly, that our souls be not lost forever!”

They knelt in prayer, signing themselves with the cross, surprised, indeed, that their hands did not refuse their mission in punishment for their sin. The noonday sun beat mercilessly upon the veiled heads as they bent in petition. At last Sister Catalina interrupted the droning cadence.

“Sister whom God hath blessed with blindness, I will lead thee to this evil thing. Thine eyes are closed against its wiles. Take it, thou, to the chapel, and there, with a taper lit at the altar, we will burn it, that it may return to the Father of Lies, who sent it.”

Sister Eulalia winced with fear, but realizing her peculiar mission she suffered herself to be led by the trembling nun till her fingers closed on the cursed paper. Painfully, on their knees, as one mounts the holy stairs in penance, they crawled to the chapel and prostrated themselves at the rail. With tears of remorse, the sisters embraced. A taper, one of the precious few in the tin box under the altar-lace, was lighted at the flame of the tiny red lamp. The print as it flared up seemed to show the pictured faces in twisted grimace; then it blackened, withered to ash, and dispersed in gray filaments.

For a moment the penitents remained in silent contemplation, then with one accord they crossed the patio to the refectory. Though the reverend Mother hear them not, yet they must make confession.

As they entered they stopped short, spellbound. The opaque black eyes were open wide, staring at them from the crystalline whiteness of the Mother Superior’s face. To the culprits that gaze was as accusing as any clarion voice of Judgment. They bowed their heads.

The reverend Mother’s lips moved.

“Vanitas vanitatum!” she cried, and again—“Vanitas vanitatum!”
