Stevens watched the last of them vanish, then felt a hand take his. "They--they didn't hurt you?" Silently he drew her through the door and their bare feet felt the loam of the clearing. The night wind fanned their faces. He turned to her. "I made them run," he laughed, and she smiled. Markett was used to the bursts of childlike glee, and she loved her husband. He had insisted upon some sort of ceremony which apparently was tied up with Roald. And beside the usual broad grin was a kind of shrewd, calculating glint. "_They_ can't fight. They've forgotten how. But now they know it." "Then," she whispered, "we're safe." "Safe," he repeated broodingly. "From men, yes. But they have their machines.
