Earthman, Come Home

“speech” of muscle interplay and posture as readily as he could spoken dialogue, Heldon’s expression was as clear as a signed confession.

“Certainly,” the Proctor said. “Is that all?”

“By no means. I think you ought to rip out about half of these circuits, and install transistors wherever they can be used; we can sell you the necessary germanium at the legal rate. You’ve got two or three hundred tubes to a unit here, by my estimate, and if you have a tube failure in flight… well, the only word that fits what would happen then is blooey!”

“Will you be able to show us how?”

“Probably,” the mayor said. “If you’ll allow me to inspect the whole system, I can give you an exact answer.”

“All right,” Heldon said. “But don’t delay. I can’t count on more than another half-day at most.”

This was better than Amalfi had expected—miles better. Given that much time, he could trace at least enough of the leads to locate the master control. That Heldon’s expression failed totally to match the content of his speech disturbed Amalfi profoundly, but there was nothing that he could do that would alter that now. He pulled paper and stylus out of Karst’s pack and began to make rapid sketches of the wiring before him.

After he had a fairly clear idea of the first generator’s set-up, it was easier to block in the main features of the second. It took time, but Heldon did not seem to tire.

The third spindizzy completed the picture, leaving Amalfi wondering what the fourth one was for. It turned out to be a booster, designed to compensate for the losses of the others wherever the main curve of their output failed to conform to the specs laid down for it by the crude, over-all regenerative circuit. The booster was located on the backside of the feedback loop, behind the computer rather than ahead of it, so that all the computer’s corrections had to pass through it; the result, Amalfi was sure, would be a small but serious “base surge” every time any correction was applied. The spindizzies of IMT seemed to have been wired together by Cro-Magnon Man.

But they would fly the city. That was what counted.

Amalfi finished his examination of the booster generator and straightened up, painfully, stretching the muscles of his back. He had no idea how many hours he had consumed. It seemed as though months had passed. Heldon was still watching him, deep blue circles under his eyes, but still wide awake and watchful.

And Amalfi had found no point anywhere in the underground chamber from which the spindizzies of IMT could be controlled. The control point was somewhere else; the main control cable ran into a pipe which shot straight up through the top of the cavern.

…IMT made the sky Fall…

Amalfi yawned ostentatiously and bent back to fastening the plate over the booster’s observation port. Karst squatted near him, frankly asleep, as relaxed and comfortable as a cat drowsing on a high ledge. Heldon watched.

“I’m going to have to do the job for you,” Amalfi said. “It’s really major; might take weeks.”

“I thought you would say so,” Heldon said. “And I was glad to give you the time to find out. But I do not think we will make any such replacements.”

“You need ’em.”

“Possibly. But obviously there is a big factor of safety in the apparatus, or our ancestors would never have flown the city at all. You will understand, Mayor Amalfi, that we cannot risk your doing something to the machines which we cannot do ourselves, on the unlikely assumption that you are increasing their efficiency. If they will run as they are, that will have to be good enough.”

“Oh, they’ll run,” Amalfi said. He began, methodically, to pack up his equipment. “For a while. I’ll tell you flatly that they’re not safe to operate, all the same.”

Heldon shrugged and went down the spiral metal stairs to the floor of the chamber. Amalfi rummaged in the pack a moment more. Then he ostentatiously kicked Karst awake—and kicked hard, for he knew better than to play-act with a born overseer for an audience—and motioned the serf to pick up the bundle. They went down after Heldon.

The Proctor was smiling, and it was not a nice smile. “Not safe?” he said. “No, I never supposed that they were. But I think now that the dangers are mostly political.”

“Why?” Amalfi damanded, trying to moderate his breathing. He was suddenly almost exhausted; it had taken—how many hours? He had no idea.

“Are you aware of the time, Mayor Amalfi?”

“About morning, I’d judge,” Amalfi said dully, jerking the pack more firmly onto Karst’s drooping left shoulder. “Late, anyhow.”

“Very late,” Heldon said. He was not disguising his expression now. He was openly crowing. “The contract between your city and mine expired at noon today. It is now nearly an hour after noon; we have been here all night and morning. And your city is still on our soil, in violation of the contract, Mayor Amalfi.”

“An oversight—”

“No; a victory.” Heldon drew a tiny silver tube from the folds of his robe and blew into it. “Mayor Amalfi, you may consider yourself a prisoner of war.”

The little silver tube had made no audible sound, but there were already ten men in the room. The mesotron rifles they carried were of an ancient design, probably pre-Kammerman, like the spindizzies of IMT.

But, like the spindizzies, they looked as though they would work.

Karst froze; Amalfi unfroze him by jabbing him surreptitiously in the ribs with a finger, and began to unload the contents of his own small pack into Karst’s.

“You’ve called the Earth police, I suppose?” he said.

“Long ago. That way of escape will be cut by now. Let me say, Mayor Amalfi, that if you expected to find down here any controls that you might disable—and I was quite prepared to allow you to search for them—you expected too much stupidity from me.”

Amalfi said nothing. He went on methodically repacking the equipment.

“You are making too many motions, Mayor Amalfi. Put your hands up in the air and turn around very slowly.”

Amalfi put up his hands and turned. In each hand he held a small black object about the size and shape of an egg.

“I expected only as much stupidity as I got,” he said conversationally. “You can see what I’m holding up there. I can and will drop one or both of them if I’m shot. I may drop them anyhow. I’m tired of your back-cluster ghost town.”

Heldon snorted. “Explosives? Gas? Ridiculous; nothing so small could contain enough energy to destroy the city; and you have no masks. Do you take me for a fool?”

“Events prove you one,” Amalfi said steadily. “The possibility was quite large that you would try to ambush me, once you had me in the city. I could have forestalled that by bringing a guard with me. You haven’t met my perimeter police; they’re tough boys, and they’ve been off duty so long that they’d love the chance to tangle with your palace crew. Didn’t it occur to you that I left my city without a bodyguard only because I had less cumbersome ways of protecting myself?”

“Eggs,” Heldon said scornfully.

“As a matter of fact, they are eggs; the black color is an annaline stain, put on the shells as a warning. They contain chick embryos inoculated with a two-hour alveolytic mutated Terrestrial rickettsialpox—a new air-borne strain developed in our own BW lab. Free space makes a wonderful laboratory for that kind of trick; an Okie town specializing in agronomy taught us the techniques a couple of centuries back. Just a couple of eggs—but if I were to drop them, you would have to crawl on your belly behind me all the way back to my city to get the antibiotic shot that’s specific for the disease; we developed that ourselves, too.”

There was a brief silence, made all the more empty by the hoarse breathing of the Proctor. The armed men
