He wondered how soon the next seed-cloud would come.
"What are we going to do, Matt? Is there any way...." McLaren wasn't thinking about himself. He was looking at the valley like Lucifer yearning at Paradise, and he was thinking of Viki. Not just Viki alone, but Viki as a symbol of thirty-eight hundred wanderers on the face of Venus.
"I don't know," said Harker. "The pass is out, and the caves are out ... hey! Remember when we were fighting off those critters by the river and you nearly started a cave-in throwing rocks? There was a fault there, right over the edge of the lake. An earthquake split. If we could get at it from the top and shake it down...."
It was a minute before McLaren caught on. His eyes widened. "A slide would dam up the lake...."
"If the level rose enough, the Swimmers could get out." Harker gazed with sultry eyes at the bobbing flower heads below.
"But if the valley's flooded, Matt, and those critters take over, where does that leave our people?"
"There wouldn't be too much of a slide, I don't think. The rock's solid on both sides of the fault. And anyway, the weight of the water backed up there would push through anything, even a concrete dam, in a couple of weeks." Harker studied the valley floor intently. "See the way that slopes there? Even if the slide didn't wash out, a little digging would drain the flood off down the pass. We'd just be making a new river."
"Maybe." McLaren nodded. "I guess so. But that still leaves the Swimmers. I don't think they'd be any nicer than these babies about giving up their land." His tone said he would rather fight Button's people any day.
Harker's mouth twisted in a slow grin. "The Swimmers are water creatures, Rory. Amphibious. Also, they've lived underground, in total darkness, for God knows how long. You know what happens to angleworms when you get 'em out in the light. You know what happens to fungus that grows in the dark." He ran his fingers over his skin, almost with reverence. "Noticed anything about yourself, Rory? Or have you been too busy."
McLaren stared. He rubbed his own skin, and winced, and rubbed again, watching his fingers leave streaks of livid white that faded instantly. "Sunburn," he said wonderingly. "My God. Sunburn!"
