More smoke billowed over Liu Han and Liu Mei. They both coughed horribly, like women dying of consumption. Behind them, people shrieked in panic. Above the shrieks came the crackle of flames. “The fire is moving faster than we are,” Liu Mei said, fear in her voice if not on her impassive face.

“I know,” Liu Han answered grimly. She had a knife in a hidden sheath strapped to her ankle; she didn’t go anywhere unarmed these days. If she took it out and started slashing at the people ahead of her, would it clear a path so she and Liu Mei could outrun the flames? The only thing that kept her from doing it was the cold judgment that it wouldn’t help.

And then, without warning, the pressure eased. Like melon seeds squeezed between the fingers, she and Liu Mei popped out onto a wider street, one with cobblestones rather than just dirt. She hadn’t even known it was close by, for she couldn’t see over the backs of the people ahead. Liu Mei hadn’t seen it either, though she was a couple of inches taller than her mother-Bobby Fiore, her American father, had been a big man by Chinese standards.

Now people could move faster. Liu Han and Liu Mei fled the fire, and gained on it. “Gods and spirits be praised,” Liu Han gasped, even though, as a good Marxist-Leninist, she wasn’t supposed to believe in gods or spirits. “I think we’ll get away.”

Liu Mei looked back over her shoulder. She could do that now without so much fear of getting trampled after a misstep. “The rooming house must be burning,” she said in a stricken voice.

“Yes, I think so,” Liu Han said. “We are alive. We will stay alive, and find another place to live. The Party will help us, if we need help. Things are not important. We didn’t have many things to lose, anyhow.” Having grown up in a peasant village, she needed few things to keep her going.

But tears streamed down Liu Mei’s expressionless, soot-streaked (and, yes, rather big-nosed) face. “The photographs we got in the United States,” she said in a broken voice. “The photographs of my father and his ancestors.”

“Oh,” Liu Han said, and put a consoling arm around her daughter. Ancestors mattered in China; filial piety ran deep, even among Party members. Liu Han had never imagined that Liu Mei would be able to learn anything about Bobby Fiore and his family, even after leaving China for the United States. But Yeager, the expert on scaly devils with whom she’d talked, had turned out to be a friend of Fiore’s, and had put her and Liu Mei in touch with his family. Everything the Fiores had sent was indeed bound to be going up in flames. Liu Han sighed. “You know what you know. If peace comes back”-she was too honest to say, When peace comes back- “we can get in touch with the Americans again.”

Liu Mei nodded. “Yes, that’s true,” she said. “Thank you, Mother. That does make it easier to bear. I thought my family was being all uprooted.”

“I understand.” No one had tended the graves of Liu Han’s ancestors for a long time. She didn’t even know if the village near Hankow had any people left in it these days. How many times had the red-hot rake of war passed through it since the little scaly devils carried her off into captivity?

A roar in the air that might have come from a furious dragon’s throat warned her the little devils’ airplanes were returning for another attack run. All over Peking, machine guns started shooting into the air even though their targets weren’t yet in sight. Before long, those bullets would start falling back to earth. Some would hit people in the head and kill them, too.

All that passed through Liu Han’s mind in a couple of seconds. Then the scaly devils’ killercraft roared low overhead. One of their pilots must have spied the swarm of people in the street because of the fire, for he cut loose with his cannon. When one of those shells struck home, it tore two or three people into bloody gobbets of flesh that looked as if they belonged in a butcher’s shop, then exploded and wounded another half a dozen. In that tight-packed crowd, the little scaly devil had a target he could hardly miss.

The attack itself lasted only a moment. Then the killercraft that had fired was gone, almost as fast as the sound of its passage. The horror lasted longer. Men and women close by Liu Han and Liu Mei were ripped to bits. Their blood splattered the two women. Along with its iron stink, Liu Han smelled the more familiar reek of night soil as shells and their fragments ripped guts open. The wounded, those unlucky enough not to die at once, shrieked and howled and wailed. So did men and women all around them, seeing what they had become.

Liu Han shouted: “Don’t scream! Don’t run! Help the injured! People must be strong together, or the little scaly devils will surely defeat us.”

More because hers was a calm, clear voice than because what she said made sense, people listened and obeyed. She was bandaging a man with a shattered arm when the roar of jet engines and the pounding of machine guns again cut through every other sound. Though she ground her teeth, she kept on working on the injured man. Peking was a vast city. Surely the killercraft would assail some distant part.

But they roared right overhead. Instead of ordinary bombs, they released swarms of little spheres. “Be careful of those!” Liu Han and Liu Mei cried together. Some of the spheres were tiny mines that were hard to see but could blow up a bicycle or a man unlucky enough to go over them. Others…

Others started squawking in Chinese: “Surrender! You cannot defeat the scaly devils! Give up while you still live!” Someone stomped one of those to silence it. It exploded, a sharp, flat bark. The woman stared at the bloody stump that had replaced her foot, then toppled screeching to the ground.

“Even if we hold Peking, I wonder if anyone will be left alive inside the walls,” Liu Han said glumly.

“That is not a proper revolutionary sentiment,” Liu Mei said. Her mother nodded, accepting the criticism. But Liu Han, twice her daughter’s age, had seen far too much to be certain proper revolutionary sentiment told all the truth there was to tell.

As Lieutenant Colonel Johannes Drucker stopped his Volkswagen at one of the three traffic lights Greifswald boasted, drizzle began to fall. That was nothing out of the ordinary in the north German town: only a few kilometers from the Baltic, Greifswald knew fog and mist and drizzle and rain with great intimacy. It knew snow and ice, too, but the season for them was past-Drucker hoped so, anyhow.

He pulled the windshield-wiper knob. As the rubber blades began traveling streakily across the glass in front of him, he rolled up the driver’s-side window to keep the rain out of the automobile. His wife, Kathe, did the same thing on the passenger’s side.

With the two of them in the front, and with Heinrich, Claudia, and Adolf squeezed into the back, the inside of the hydrogen-burning VW’s windows began to steam up. Drucker turned on the heater and vented the warm air up to the inside of the windshield. He wasn’t sure how much good it did, or if it did any good at all.

The light turned green. “Go, Father,” Heinrich said impatiently, even as Drucker put the auto into first gear. Heinrich was sixteen now, and learning to drive. Had he known half as much about the business as he thought he did, he would have known twice as much as he really did.

As the Volkswagen went through the intersection-no more slowly than anyone else-a great roar penetrated the drizzle and the windows. Peenemunde was only about thirty kilometers east of Greifswald. When a rocket went up, everybody in town knew about it.

“Who would that be, Father?” Adolf asked, sounding as excited as any eleven-year-old would have at the prospect of blasting into space.

“It’s Joachim’s-uh, Major Spitzler’s-turn in the rotation,” Drucker answered. “Unless he came down with food poisoning”-a euphemism for getting drunk, but Adolf didn’t need to know that-“last night, he’s heading for orbit right now.”
