"Yes. Getting tired?"
"No."
"Why, then?"
David did not answer. He plodded carefully along behind, picking his way over the ash. His legs and shoes were gray with dust. His pinched face was streaked, lines of gray ash in rivulets down the pale white of his skin. There was no color to his face. Typical of the new children, growing up in cellars and sewers and underground shelters. Hendricks slowed down. He lifted his field-glasses and studied the ground ahead of him. Were they there, someplace, waiting for him? Watching him, the way his men had watched the Russian runner? A chill went up his back. Maybe they were getting their guns ready, preparing to fire, the way his men had prepared, made ready to kill. Hendricks stopped, wiping perspiration from his face.
"Damn." It made him uneasy. But he should be expected.
The situation was different.
He strode over the ash, holding his gun tightly with both hands. Behind him came Davis. Hendricks peered around, tight-lipped. Any second it might happen. A burst of white light, a blast, carefully aimed from inside a deep concrete bunker.
He raised his arm and waved it around in a circle. Nothing moved. To the right a long ridge ran, topped with dead tree trunks. A few wild vines had grown up around the trees, remains of arbors. And the eternal dark weeds. Hendricks studied the ridge. Was anything up there? Perfect place for a lookout.
He approached the ridge warily, David coming silently behind. If it were his command he'd have a sentry up there, watching for troops trying to infiltrate into the command area. Of course, if it were his command there would be claws around the area for full protection. He stopped, feet apart, hands on his hips.
"Are we there?" David said.
"Almost."
"Why have we stopped?"
"I don't want to take any chances." Hendricks advanced slowly. Now the ridge lay directly beside him, along his right. Overlooking him. His uneasy feeling increased. If an Ivan were up there he wouldn't have a chance. He waved his arm again. They should be expecting someone in the UN uniform, in response to the note capsule. Unless the whole thing was a trap.
"Keep up with me." He turned towards David. "Don't drop behind."
"With you?"
"Up beside me. We're close. We can't take any chances. Come on."
"I'll be all right." David remained behind him, in the rear, a few paces away, still clutching his teddy bear.
"Have it your way." Hendricks raised his glasses again, suddenly tense. For a moment -- had something moved? He scanned the ridge carefully. Everything was silent. Dead. No life up there, only tree trunks and ash. Maybe a few rats. The big black rats that had survived the claws. Mutants built their own shelters out of saliva and ash. Some kind of plaster. Adaptation.
He started forward again. A tall figure came out on the ridge above him, cloak flapping. Gray-green. A Russian. Behind him a second soldier appeared, Russian. Both lifted their guns, aiming. Hendricks froze. He opened his mouth. The soldiers were kneeling, sighting down the side of the slope. A third figure had joined them on the ridge top, a smaller figure in gray-green. A woman. She stood behind the other two.
Hendricks found his voice. "Stop!" He waved at them frantically. "I'm --"
The two Russians fired. Behind Hendricks there was a faint pop. Waves of heat lapped against him, throwing him to the ground. Ash tore at his face, grinding into his eyes and nose. Choking, he pulled himself to his knees. It was all a trap. He was finished. He had come to be killed, like a steer. The soldiers and the woman were coming down the side of the ridge towards him, sliding down through the soft ash. Hendricks was numb. His head throbbed. Awkwardly, he got his rifle up and took aim. It weighed a thousand tons; he could hardly hold it. His nose and cheeks stung. The air was full of the blast smell, a bitter acrid stench.
"Don't fire," the first Russian said, in heavily accented English.
The three of them came up to him, surrounding him. "Put down your rifle, Yank," the other said.
Hendricks was dazed. Everything had happened so fast. He had been caught. And they had blasted the boy. He turned his head. David was gone. What remained of him was strewn across the ground.
The three Russians studied him curiously. Hendricks sat, wiping blood from his nose, picking out bits of ash. He shook his head, trying to clear it. "Why did you do it?" he murmured thickly. "The boy."
"Why?" One of the soldiers helped him roughly to his feet He turned Hendricks around. "Look."
Hendricks closed his eyes.
"Look." The two Russians pulled him forward. "See. Hurry up. There isn't much time to spare, Yank!"
Hendricks looked. And gasped.
"See now? Now do you understand?"
From the remains of David a metal wheel rolled. Relays, glinting metal. Parts, wiring. One of the Russians kicked at the heap of remains. Parts popped out, rolling away, wheels and springs and rods. A plastic section fell in, half charred. Hendricks bent shakily down. The front of the head had come off. He could make out the intricate brain, wires and relays, tiny tubes and switches, thousands of minute studs --
"A robot," the soldier holding his arm said. "We watched it tagging you."
"Tagging me?"
"That's their way. They tag along with you. Into the bunker. That's how they get in."
Hendricks blinked, dazed. "But --"
"Come on." They led him towards the ridge, sliding and slipping on the ash. The woman reached the top and stood waiting for them.
"The forward command," Hendricks muttered. "I came to negotiate with the Soviet --"
"There is no more forward command. They got in. We'll explain." They reached the top of the ridge. "We're all that's left. The three of us. The rest were down in the bunker."
"This way. Down this way." The woman unscrewed a lid, a gray manhole cover set in the ground. "Get in."
Hendricks lowered himself. The two soldiers and the woman came behind him, following him down the ladder. The woman closed the lid after them, bolting it tightly into place.
"Good thing we saw you," one of the two soldiers grunted.
"It had tagged you about as far as it was going to."
"Give me one of your cigarettes," the woman said. "I haven't had an American cigarette for weeks."
Hendricks pushed the pack to her. She took a cigarette and passed the pack to the two soldiers. In the corner of the small room the lamp gleamed fitfully. The room was low-ceilinged, cramped. The four of them sat around a small wood table. A few dirty dishes were stacked to one side. Behind a ragged curtain a second room was partly visible. Hendricks saw the corner of a cot, some blankets, clothes hung on a hook.
"We were here," the soldier beside him said. He took off his helmet, pushing his blond hair back. "I'm Corporal Rudi Maxer. Polish. Impressed in the Soviet Army two years ago." He held out his hand.
Hendricks hesitated and then shook. "Major Joseph Hendricks."
"Klaus Epstein." The other soldier shook with him, a small dark man with thinning hair. Epstein plucked nervously at his ear. "Austrian. Impressed God knows when. I don't remember. The three of us were here, Rudi and I, with Tasso." He indicated the woman. "That's how we escaped. All the rest were down in the bunker."
"And -- and they got in?"
Epstein lit a cigarette. "First just one of them. The kind that tagged you. Then it let others in."
Hendricks became alert. "The kind? Are there more than one kind?"
"The little boy. David. David holding his teddy bear. That's Variety Three. The most effective."
"What are the other types?"
Epstein reached into his coat. "Here." He tossed a packet of photographs on to the table, tied with a string. "Look for yourself."
