This need for very fresh corpses had been West’s moral undoing. They were hard to get, and one awful day he had secured his specimen while it was still alive and vigorous. A struggle, a needle, and a powerful alkaloid had transformed it to a very fresh corpse, and the experiment had succeeded for a brief and memorable moment; but West had emerged with a soul calloused and seared, and a hardened eye which sometimes glanced with a kind of hideous and calculating appraisal at men of especially sensitive brain and especially vigorous physique. Toward the last I became acutely afraid of West, for he began to look at me that way. People did not seem to notice his glances, but they noticed my fear; and after his disappearance used that as a basis for some absurd suspicions.
