Yes, a stir, a very faint stir somewhere down the hall—the slow, cautious opening of a door, then a footfall—or had I imagined the latter? I could hear nothing now.

Pushing open my own door, I looked cautiously out. Only the pale face of Sinclair confronted me. He was peering from the corner of an adjacent passageway, the moonlight at his back. Advancing, we met in silence. For the moment we seemed to be the only persons awake in the vast house.

"I thought I heard a step," was my cautious whisper after a moment of intense listening.

"Where?"

I pointed toward that portion of the house where the ladies' rooms were situated.

"That is not what I heard," was his murmured protest, "what I heard was a creak in the small stairway running down at the end of the hall where my room is."

"One of the servants," I ventured, and for a moment we stood irresolute. Then we both turned rigid as some sound arose in one of the far-off rooms, only to quickly relax again as that sound resolved itself into a murmur of muffled voices. Where there was talking there could be no danger of the special event we feared. Our relief was so great we both smiled. Next instant his face and, I have no doubt, my own, turned the color of clay and Sinclair went reeling back against the wall.

A scream had risen in this sleeping house—a piercing and insistent scream such as raises the hair and curdles the blood.
