They climbed back down the ladder slowly, into the warm cellar. Klaus bolted the lid behind them. Tasso waited for them, her face expressionless. "Any luck?" she asked. Neither of them answered. "Well?" Klaus said at last. "What do you think, Major? Was it your officer, or was it one of _them_?" "I don't know." "Then we're just where we were before." Hendricks stared down at the floor, his jaw set. "We'll have to go. To be sure." "Anyhow, we have food here for only a few weeks. We'd have to go up after that, in any case." "Apparently so." "What's wrong?" Tasso demanded. "Did you get across to your bunker? What's the matter?" "It may have been one of my men," Hendricks said slowly. "Or it may have been one of _them_. But we'll never know standing here." He examined his watch. "Let's turn in and get some sleep. We want to be up early tomorrow." "Early?" "Our best chance to get through the claws should be early in the morning," Hendricks said. * * * * * The morning was crisp and clear. Major Hendricks studied the countryside through his fieldglasses. "See anything?" Klaus said. "No." "Can you make out our bunkers?" "Which way?" "Here." Klaus took the glasses and adjusted them. "I know where to look." He looked a long time, silently. Tasso came to the top of the tunnel and stepped up onto the ground. "Anything?" "No." Klaus passed the glasses back to Hendricks. "They're out of sight. Come on. Let's not stay here." The three of them made their way down the side of the ridge, sliding in the soft ash. Across a flat rock a lizard scuttled. They stopped instantly, rigid. "What was it?" Klaus muttered. "A lizard." The lizard ran on, hurrying through the ash. It was exactly the same color as the ash. "Perfect adaptation," Klaus said. "Proves we were right. Lysenko, I mean." They reached the bottom of the ridge and stopped, standing close together, looking around them. "Let's go." Hendricks started off. "It's a good long trip, on foot." Klaus fell in beside him. Tasso walked behind, her pistol held alertly. "Major, I've been meaning to ask you something," Klaus said. "How did you run across the David? The one that was tagging you." "I met it along the way. In some ruins." "What did it say?" "Not much. It said it was alone. By itself." "You couldn't tell it was a machine? It talked like a living person? You never suspected?" "It didn't say much. I noticed nothing unusual. "It's strange, machines so much like people that you can be fooled. Almost alive. I wonder where it'll end." "They're doing what you Yanks designed them to do," Tasso said. "You designed them to hunt out life and destroy. Human life. Wherever they find it." * * * * * Hendricks was watching Klaus intently. "Why did you ask me? What's on your mind?" "Nothing," Klaus answered. "Klaus thinks you're the Second Variety," Tasso said calmly, from behind them. "Now he's got his eye on you."
