I never saw anything more of the stranger, or the lady.

I never heard of any sudden death, or accident, or disappearance having taken place about that time; and I never even obtained any clue to the neighborhood of the house in which these things took place.

Often and often afterwards, when I was strolling by night along the streets of Rome, I lingered before some old palazzo, and fancied that I recognised the gloomy outline that caught my eye in that hurried transit from the carriage to the house.

Often and often I paused and started, thinking that I had found at last the very side-door by which I entered.

But these were mere guesses after all.
