"What are they supposed to do—see in the dark?"

He laughed humorlessly. "That'd be a boon for a reporter, wouldn't it? No, my friend, much worse than that. Try them on. Go ahead."

I did. "Well?"

"Notice anything peculiar?"

"Look at the sky," he directed. "See anything unusual?" He stood waiting, expectant.
