“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.”
