The treachery knocked me in a heap for the moment. Then leaping up and flinging my door wide, I stumbled through the uncertain light of the passage into the front hall.

There was a fan-shaped light over the door, and the place was very still and gray. A quick thought, or rather a sudden prophetic guess at the truth, made me turn to the figure of the mastiff curled under the hall table.

I laid my hand on the scruff of his neck. He was quite limp, and my fingers sank into the flesh on either side of the vertebrae. Digging them deeper, I dragged him out into the middle of the hall, and pulled the front door open to see the better.

His throat was gashed from ear to ear.

How many seconds passed after I dropped the senseless lump on the floor, and before I made another movement, it would puzzle me to say. Twice I stirred a foot as if to run out at the door. Then, changing my mind, I stepped over the mastiff, and ran up the staircase. The light no longer shone out into the left-hand passage; but groping down it, I found the study door open, as before, and passed in. A sick light stole through the blinds—enough for me to distinguish the glasses and decanters on the table, and find my way to the curtain that hung before the room where the light had first attracted me.

I pushed the curtain aside, paused for a moment, and listened to the violent beat of my heart; then felt for the door handle and turned it.

All I could see at first; was that the chamber was small; next, that the light patch in a line with the window was the white coverlet of a bed; and next, that somebody, or something, lay on the bed.

I listened again. There was no sound in the room; no heart beating but my own. I reached out a hand to pull up the blind, and drew it back again. I dared not.

The daylight grew, minute by minute, on the dull parallelogram of the blind, and minute by minute that horrible thing on the bed took something of distinctness. The strain beat me at last. I fetched a veritable yell to give myself courage, and, reaching for the cord, pulled up the blind as fast as it would go.
