Cities in Flight

In the meantime, there was exactly nothing Amalfi could do about it. Even his contact with his own city was cut off.

“It isn’t your city,” the voice said, suddenly deceptively reasonable. “It’s our city. You’re hijacking us. But we won’t let you.”

“How were we supposed to know any of you were still alive?” Amalfi demanded angrily. “You didn’t answer our calls. Is it our fault if you didn’t hear them? We thought this town was open for salvage—”

His voice was abruptly obliterated by a new one, enormous yet familiar, which came slamming into his helmet as if it intended to drive him out of his suit entirely.

“EARTH POLICE AAEMERGENCY ACOLYTE CLUSTER CONDENSATION XIIIARM B ETA,” it thundered. “S YSTEM UNDER ATTACK BY MASS ARMY OF TRAMP CITIES. POLICE AID URGENTLY NEEDED. LERNER LIEUTENANT F ORTY-FIFTH BORDER SECURITY G ROUP ACTING COMMANDER CLUSTER DEFENSE FORCES. A CKNOWLEDGE. ”

Amalfi whistled soundlessly through his teeth. There was evidently a Dirac transceiver in operation somewhere inside the close-drawn spindizzy screen, or his helmet phones wouldn’t have caught Lerner’s yell for help; Diracs were too bulky for the usual proxy, let alone for a space suit. By the same token, everybody else in the galaxy possessing Dirac equipment had heard that yell—it had been the instantaneous propagation of Dirac pulses that had dealt the death blow to the West’s hypercomplex relativity theories millennia ago.

And if a Dirac sender was open inside this bubble …

“LERNER ACOLYTE DEFENSE F ORCES YOUR MESSAGE IN. S QUADRON ASSIGNED YOUR CONDENSATION ON WAY. H ANG ON. BETA ARM COMMAND E ARTH. ”

… then Amalfi could use it. He flipped the chest switch and shouted, “Hazleton, are your nutcrackers rolling?”

“Rolling, boss,” Hazleton shot back instantly. “Another ninety seconds and—”

“Too late, this sector will tear loose before then. Tune up our own screen to twenty-four per cent and hold—”

He realized suddenly that he was shouting into a dead mike. The Okies here had caught on belatedly to what was happening, and had cut the power to their Dirac. Had that last, crucial, incomplete sentence gotten through, even a fragment of it? Or …

Deep down under Amalfi’s feet an alarming sound began to rise. It was part screech, part monstrous rockslide, part prolonged and hollow groan. Amalfi’s teeth began to itch in their sockets, and his bowels stirred slightly. He grinned.

The message had gotten through—or enough of it to enable Hazleton to guess the rest. The one spindizzy holding this field was going sour. Against the combined power of the nearby drivers of Amalfi’s city, it could no longer maintain the clean space-lattice curvature it was set for.

“You’re sunk,” Amalfi told the invisible defenders quietly. “Give up now, and you’ll not be hurt. I’ll skip the TDX incident—Dulany was one of my best men, but maybe there was some reason on your side, too. Come on over with us, and you’ll have a city to call your own again. This one isn’t any good to you any more, that’s obvious.”

There was no answer.

Patterns began to race across the close-pressing black sky. The nutcrackers—portable generators designed to heterodyne a spin-dizzy field to the overload point—were being brought to bear. The single tortured spindizzy howled with anguish.

“Speak up, up there,” Amalfi said. “I’m trying to be fair, but if you force me to drive you out—”

“Vultures,” the cracked voice sobbed.

The window aloft lit up with a searing glare and burst outward. A long tongue of red flame winnowed out over the street. The spindizzy screen went down at once, and with it the awful noise from the city’s power deck; but it was several minutes before Amalfi’s dazzled eyes could see the stars again.

He stared up at the exploded scar on the side of the building, outlined in orange heat swiftly dimming. He felt a little sick.

“TDX again,” he said softly. “Consistent to the last, the poor sick idiots.”

“Mr. Mayor?”

“Here.”

“This is the proxy room. There’s a regular stampede going on in the jungle. The cities are streaming away from the red star as fast as they can tune up. No discernible order—just a mob, and a panicky mob, too. No signs of anything being done for the wounded cities; and it looks to me like they’re just being left for Lerner to break up as soon as he gets up enough courage.”

Amalfi nodded to himself. “All right, O’Brian, launch the big drone now. I want that drone to go with those cities and stick with them all the way. Pilot it personally; it’s highly detectable, and there’ll probably be several attempts to destroy it, so be ready to dodge.”

“I will, sir. Mr. Hazleton just launched her a moment ago; I’m giving her the gun right now.”

For some reason this did not improve Amalfi’s temper in the least.
