She pounded a fist softly on my back. We were cheek to cheek; I couldn’t see her face. “I don’t want to believe it. I don’t dare. Stan, nothing like this has ever happened before. How can you know?”

“Something did.”

“What? I don’t believe it. We’d remember.”

“Do you remember the first moon landing? Aldrin and Armstrong?”

“Of course. We watched it at Earl’s Lunar Landing Party.”

“They landed on the biggest, flattest place they could find on the moon. They sent back several hours of jumpy home movies, took a lot of very clear pictures, left corrugated footprints all over the place. And they came home with a bunch of rocks.

“Remember? People said it was a long way to go for rocks. But the first thing anyone noticed about those rocks was that they were half melted.

“Sometime in the past, oh, say the past hundred thousand years; there’s no way of marking it closer than that—the sun flared up. It didn’t stay hot enough long enough to leave any marks on the Earth. But the moon doesn’t have an atmosphere to protect it. All the rocks melted on one side.”

The air was warm and damp. I took off my coat, which was heavy with rainwater. I fished the cigarettes and matches out, lit a cigarette and exhaled past Leslie’s ear.

“We’d remember. It couldn’t have been this bad.”

“I’m not so sure. Suppose it happened over the Pacific? It wouldn’t do that much damage. Or over the American continents. It would have sterilized some plants and animals and burned down a lot of forests, and who’d know? The sun is a four percent variable star. Maybe it gets a touch more variable than that, every so often.”

Something shattered in the bedroom. A window? A wet wind touched us, and the shriek of the storm was louder.

“Then we could live through this,” Leslie said hesitantly.
