And, to my surprise, the door of the dining room was open. It had been opened. I paused on the threshold, staring about me. I think I fully expected to see a figure blocked in the shadows against the heavy sideboard, or looming on the other side beneath his portrait. But the room was empty; I felt it empty. Through the wide bow-windows that gave on to the verandah came an uncertain glimmer that even shone reflected in the polished surface of the dinner-table, and again I perceived the stiff outline of chairs, waiting tenantless all round it, two larger ones with high carved backs at either end. The monkey trees on the upper terrace, too, were visible outside against the sky, and the solemn crests of the wellingtonias on the terraces below. The enormous clock on the mantelpiece ticked very slowly, as though its machinery were running down, and I made out the pale round patch that was its face. Resisting my first inclination to turn the lights up--my hand had gone so far as to finger the friendly knob--I crossed the room so carefully that no single board creaked, nor a single chair, as I rested a hand upon its back, moved on the parquet flooring. I turned neither to the right nor left, nor did I once look back. I went towards the long corridor filled with priceless _objets d'art_, that led through various antechambers into the spacious music-room, and only at the mouth of this corridor did I next halt a moment in uncertainty. For this long corridor, lit faintly by high windows on the left from the verandah, was very narrow, owing to the mass of shelves and fancy tables it contained. It was not that I feared to knock over precious things as I went, but, that, because of its ungenerous width, there would be no room to pass another person--if I met one. And the certainty had suddenly come upon me that somewhere in this corridor another person at this actual moment stood. Here, somehow, amid all this dead atmosphere of furniture and impersonal emptiness, lay the hint of a living human presence; and with such conviction did it come upon me, that my hand instinctively gripped the pistol in my pocket before I could even think. Either some one had passed along this corridor just before me, or some one lay waiting at its farther end--withdrawn or flattened into one of the little recesses, to let me pass. It was the person who had opened the door. And the blood ran from my heart as I realized it.
