“Ah, no,” she said quickly. “I was in ignorance of his absence until—until my maid awoke me at a quarter-past five this morning, and told me of the awful discovery.”

About half-past nine the men joined us, a couple of dances were played, some songs were sung, and the evening passed without further event, as far as I am aware.”
