It was quite by accident I discovered this incredible invasion of Earth by lifeforms from another planet. As yet, I haven’t done anything about it; I can’t think of anything to do. I wrote to the Government, and they sent back a pamphlet on the repair and maintenance of frame houses. Anyhow, the whole thing is known; I’m not the first to discover it. Maybe it’s even under control.

I was sitting in my easy-chair, idly turning the pages of a paperbacked book someone had left on the bus, when I came across the reference that first put me on the trail. For a moment I didn’t respond. It took some time for the full import to sink in. After I’d comprehended, it seemed odd I hadn’t noticed it right away.

The reference was clearly to a nonhuman species of incredible properties, not indigenous to Earth. A species, I hasten to point out, customarily masquerading as ordinary human beings. Their disguise, however, became transparent in the face of the following observations by the author. It was at once obvious the author knew everything. Knew everything--and was taking it in his stride. The line (and I tremble remembering it even now) read:

... 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. My heart pounded and my breath choked in my windpipe. I had stumbled on an accidental mention of a totally unfamiliar race. Obviously non-Terrestrial. Yet, to the characters in the book, it was perfectly natural--which suggested they belonged to the same species.

And the author? A slow suspicion burned in my mind. The author was taking it rather too easily in his stride. Evidently, he felt this was quite a usual thing. He made absolutely no attempt to conceal this knowledge. The story continued:

... presently his eyes fastened on Julia.

Julia, being a lady, had at least the breeding to feel indignant. She is described as blushing and knitting her brows angrily. At this, I sighed with relief. They weren’t all non-Terrestrials. The narrative continues:

... slowly, calmly, his eyes examined every inch of her.

Great Scott! But here the girl turned and stomped off and the matter ended. I lay back in my chair gasping with horror. My wife and family regarded me in wonder.

“What’s wrong, dear?” my wife asked.

I couldn’t tell her. Knowledge like this was too much for the ordinary run-of-the-mill person. I had to keep it to myself. “Nothing,” I gasped. I leaped up, snatched the book, and hurried out of the room.

In the garage, I continued reading. There was more. Trembling, I read the next revealing passage:

_ ... he put his arm around Julia. Presently she asked him if he would remove his arm. He immediately did so, with a smile._
