I sat down wearily, and stared at Cronus. The screen was blank. "How did you manage to invent that thing?" I said.

"I didn't really invent it. I just—discovered it. I was tinkering with a TV set, and I changed some circuits and added a lot of gadgets, just for the hell of it.

Then one day the screen showed me a big aircar smashup. There were about ten units involved, and I told myself, 'Boy, these Class D pictures are really overdoing it.' About a week later I opened my morning paper, and there was the same smashup on page one. It took a long time to get anybody interested."

"There's not much we can do," I said, "but keep on looking."
