hadn't been heard then. It would be anybody's guess. But the voice came the day after Alpha Centauri vanished. I first heard it on my way to the store. I was walking down Lexington Avenue from the 59th Street station, looking in the dress windows to see what my competitors had to offer. Just as I was passing Mary-Belle's Frocks, and wondering how soon they'd have their Summer line in, I heard it. It was a pleasant voice, friendly. It seemed to come from just behind me, about three feet over my shoulder. "Judgment of the inhabitants of the planet Earth," it said, "will be held in five days. Please prepare yourselves for final examination and departure. This announcement will be repeated." I looked around at once to find out who was speaking. I half-expected to find a tall, cadaverous fanatic at my shoulder, some fiery-eyed fellow with flowing hair and a beard. But there was no one at all. The nearest person was about fifteen feet from me. For a moment I thought I was having a hallucination, hearing voices, that sort of thing. Then I saw that everyone else must have heard it, too. Lexington Avenue is a pretty busy place at nine o'clock in the morning. There are plenty of people hurrying back and forth, kids going to school, subways roaring beneath you, cars and buses honking. Not now. You couldn't hear a sound. Every car had stopped, right where it was. The people on the sidewalks seemed frozen practically in mid-stride. The man nearest me walked up. He was well-dressed, about my age—in his early forties. He was eyeing me with suspicion, as though I might have been responsible for the whole thing. I suppose I was looking at him in the same way. "Did you hear it?" he asked me. "Yes," I said. "Did you do it?" "No. Did you?" "Most certainly not," he said indignantly. We stood for a few seconds, just looking at each other. I think we—everybody—knew, right there and then, that it was no hoax. What with the stars disappearing, I mean. A pretty girl in a fur coat walked up to me. She was young; she looked scared, and very defiant.
