"Well, to tell the truth, Ralph, he seldom knows. He usually believes her to be at home, and I never undeceive him. Why should I?" I grunted, for I was not at all well pleased with her connivance at her sister's deceit. The sound that escaped my lips caused her to glance across at me in quick surprise. "You are displeased, dear," she said. "Tell me why. What have I done?" "I'm not displeased with you," I declared. "Only, as you know, I'm not in favour of deception, and especially so in a wife." She pursed her lips, and I thought her face went a trifle paler. She was silent for a moment, then said: "I don't see why we should discuss that, Ralph. Mary's actions concern neither of us. It is not for us to prevent her amusing herself, neither is it our duty to create unpleasantness between husband and wife."

Man is but mortal, and a beautiful woman always enchants. As she sat before me in her evening gown of some flimsy cream stuff, all frills and furbelows, she seemed perfect in her loveliness. The surroundings suited her to perfection--the old Chippendale and the palms, while the well-shaded electric lamp in its wrought-iron stand shed a mellow glow upon her, softening her features and harmonising the tints of the objects around. From beneath the hem of her skirt a neat ankle encased in its black silk stocking was thrust coquettishly forward, and her tiny patent leather slipper was stretched out to the warmth of the fire. Her pose was, however, restful and natural. She loved luxury, and made no secret of it. The hour after dinner was always her hour of laziness, and
