Pensive with her speculation, she turned her eyes, wistful with their yearning to pierce the mysteries of time, full upon the mirror, and started. An apparition, a woman's face, cunning, resentful, demon-like, was there beside her own; a woman's figure crouching, stealthy, about to spring was stealing toward her. Was it a vision, an uncanny creature of the brain? Instinctively she turned, and as she did so a large pair of hands gleamed in her face and reached for her neck. Springing up with a cry of horror, she recoiled from the threatening fingers, but in another instant she was bent backward so that her head pressed against the glass and she felt a powerful clutch upon her throat which took away the power to scream, and made her eyes feel as though they were bursting from their sockets. A voice, exultant, cruel, yet like a revivalist's chant, rang in her ears. "I've come for you. We'll go together, down to eternity. There you will scrub dirty marble floors for ever and ever." In the face in the mirror Mrs. Wilson had recognized Loretta, and she divined, as the wild figure threw itself upon her and the strong hands gripped her windpipe, that she was contending with a mad-woman. The import of the strange, accusing words was unmistakable; it was a struggle for life. Powerless to give the alarm save by inarticulate gasps, she realized that only her own strength could avail her, and that this must fail owing to the superior hold which her assailant had established. She strove with all her might to wrench herself free, but in vain. The long hands squeezed like a vise, and she was choking. She felt her senses swim, and that she was about to faint. Then with a rush a third figure intervened; someone else's hands were battling on her side, and in an instant she was free. Awaking suddenly, as one who is sleeping on guard often will, Constance had felt an instinct that something was wrong. The turning on of the electric light revealed that Loretta's bed was empty. Where had she gone? It seemed improbable that she had sought to escape from the house at that hour. Puzzled, she stepped into the hall and half-way down the staircase. There as she paused the light shining from under Mrs. Wilson's apartment on the landing below caught her eye. The next moment she heard a muffled scream. It had required all her strength and weight to tear Loretta from her victim. Having succeeded in separating them, Constance hastily put herself on the defensive, expecting a fresh attack; but Loretta, panting from her exertions, stood facing them for a moment, then burst into a strident, gleeful laugh.
