"It was terrible; it blasted him with its awfulness. As it moved it drained the life from each person in turn; it ate the people who had assembled, passed on, ate again, ate more with an endless appetite. It hated; he felt its hate. It loathed; he felt its loathing for everyone present—in fact he shared its loathing. All at once he and everyone else in the big villa were each a twisted slug, and over the fallen slug-carcasses the creature savored, lingered, but all the time coming directly toward him—or was that an illusion? If this is a hallucination, Chien thought, it is the worst I have ever had; if it is not, then it is evil reality; it’s an evil thing that kills and injures. He saw the trail of stepped-on, mashed men and women remnants behind it; he saw them trying to reassemble, to operate their crippled bodies; he heard them attempting speech."
