I had known that all along, of course, but all of a sudden the real enormity of what was happening hit me like a boot in the stomach. There sat Doc Maxey, one of the most brilliant physicists in the world—stumped. Beside him drooped Three-star General Corbin, high commander of Allied Military, and he was as helpless as a corner newsboy. A top-flight crew of research technicians stood around in the living room like so many cigar-store dummies, looking at each other blankly while the world skidded to ruin on a slippery cosmic banana peel.

Dora came over and put an arm across my shoulders. As suddenly as I had got scared I got mad.

It wasn't just the idea of the world going bust that burned me. This was a personal business that threatened Dora and me and our friends and all the millions and millions of people we had never even seen. Here was the lot of us headed A-over-T straight back to the stone ages. A few days more and people we had known and loved would be hunting each other through the streets with clubs, driven to murder and worse because a crew of greedy alien fire-worms had a taste for atomic fission.

It was a hopeless affair and I knew it. But down inside me a nagging little ghost of an idea kept whispering that we must have overlooked something, that somewhere there must be a loophole these high-voltage intellects had missed. Sometimes, I told myself, theorists can be as dumb as ordinary people. Sometimes they just can't see the trees for the woods.

"Look," I said. "We're missing a bet somewhere. We built the Di-tube in the beginning to...."

Doc gave me a pitying look. "Will you keep your infantile inspirations to yourself, Gerald? I'm trying to think."

I turned to Three-star Corbin, getting eager because the idea had just nudged me again. It wasn't clear yet—but it was there, begging to be recognized like a half-remembered name that trembles on the tip of your tongue.

"Will you listen, General? There's a chance that...."

The general gave me a poisonous glare. "Can't you see that I'm planning a course of action? Shut up or I'll have you thrown out!"

I jumped up, knocking over my coffee, and walked out. Dora came outside after me and caught my arm. "Jerry! What are you going to do?"
