The Eyes Have It
... his eyes slowly roved about the room.
Vague chills assailed me. I tried to picture the eyes. Did they roll like dimes? The passage indicated not; they seemed to move through the air, not over the surface. Rather rapidly, apparently. No one in the story was surprised. That's what tipped me off. No sign of amazement at such an outrageous thing. Later the matter was amplified.
... his eyes moved from person to person.
There it was in a nutshell. The eyes had clearly come apart from the rest of him and were on their own.
