Klaus flushed. "Why not? We sent a runner to the Yank lines and he comes back. Maybe he thought he'd find some good game here." Hendricks laughed harshly. "I came from the UN bunkers. There were human beings all around me." "Maybe you saw an opportunity to get into the Soviet lines. Maybe you saw your chance. Maybe you--" "The Soviet lines had already been taken over. Your lines had been invaded before I left my command bunker. Don't forget that." Tasso came up beside him. "That proves nothing at all, Major." "Why not?" "There appears to be little communication between the varieties. Each is made in a different factory. They don't seem to work together. You might have started for the Soviet lines without knowing anything about the work of the other varieties. Or even what the other varieties were like." "How do you know so much about the claws?" Hendricks said. "I've seen them. I've observed them. I observed them take over the Soviet bunkers." "You know quite a lot," Klaus said. "Actually, you saw very little. Strange that you should have been such an acute observer." Tasso laughed. "Do you suspect me, now?" "Forget it," Hendricks said. They walked on in silence. "Are we going the whole way on foot?" Tasso said, after awhile. "I'm not used to walking." She gazed around at the plain of ash, stretching out on all sides of them, as far as they could see. "How dreary." "It's like this all the way," Klaus said. "In a way I wish you had been in your bunker when the attack came." "Somebody else would have been with you, if not me," Klaus muttered. Tasso laughed, putting her hands in her pockets. "I suppose so." They walked on, keeping their eyes on the vast plain of silent ash around them. * * * * * The sun was setting. Hendricks made his way forward slowly, waving Tasso and Klaus back. Klaus squatted down, resting his gun butt against the ground. Tasso found a concrete slab and sat down with a sigh. "It's good to rest." "Be quiet," Klaus said sharply. Hendricks pushed up to the top of the rise ahead of them. The same rise the Russian runner had come up, the day before. Hendricks dropped down, stretching himself out, peering through his glasses at what lay beyond. Nothing was visible. Only ash and occasional trees. But there, not more than fifty yards ahead, was the entrance of the forward command bunker. The bunker from which he had come. Hendricks watched silently. No motion. No sign of life. Nothing stirred. Klaus slithered up beside him. "Where is it?" "Down there." Hendricks passed him the glasses. Clouds of ash rolled across the evening sky. The world was darkening. They had a couple of hours of light left, at the most. Probably not that much. "I don't see anything," Klaus said. "That tree there. The stump. By the pile of bricks. The entrance is to the right of the bricks." "I'll have to take your word for it."
