The Hand of Fu-Manchu by Sax Rohmer

“Who’s there?” I called sharply.

I turned and looked across the room. The window had been widely opened when I entered, and a faint fog haze hung in the apartment, seeming to veil the light of the shaded lamp. I watched the closed door intently, expecting every moment to see the knob turn. But nothing happened.

“Who’s there?” I cried again, and, crossing the room, I threw open the door.

The long corridor without, lighted only by one inhospitable lamp at a remote end, showed choked and yellowed with this same fog so characteristic of London in November. But nothing moved to right nor left of me. The New Louvre Hotel was in some respects yet incomplete, and the long passage in which I stood, despite its marble facings, had no air of comfort or good cheer; palatial it was, but inhospitable.
