A startled deerhound yelped and snarled. There was blood, I saw, in the sink,--brown, and some scarlet--and I smelt the peculiar smell of carbolic acid. Then through an open doorway beyond, in the dim light of the shadow, I saw something bound painfully upon a framework, scarred, red, and bandaged; and then blotting this out appeared the face of old Moreau, white and terrible. In a moment he had gripped me by the shoulder with a hand that was smeared red, had twisted me off my feet, and flung me headlong back into my own room. He lifted me as though I was a little child. I fell at full length upon the floor, and the door slammed and shut out the passionate intensity of his face. Then I heard the key turn in the lock, and Montgomery's voice in expostulation.

"Ruin the work of a lifetime," I heard Moreau say.

"He does not understand," said Montgomery. and other things that were inaudible.

"I can't spare the time yet," said Moreau.

The rest I did not hear. I picked myself up and stood trembling, my mind a chaos of the most horrible misgivings. Could it be possible, I thought, that such a thing as the vivisection of men was carried on here? The question shot like lightning across a tumultuous sky; and suddenly the clouded horror of my mind condensed into a vivid realisation of my own danger.
