Norman told her what he had done to revive Keren. "But here's what we do," he said, lowering Keren to a sofa. "Sade will see the empty cage and know there's something wrong when he comes in to land. He will probably attack the house. We've got to get back in the cage. Keren can vaccinate you," he nodded to Dorothy, allaying her hesitation. "When they land, I'll jump out and take care of as many as I can. Keren can get the rest from the tower."
"There's a glass cutter in the store room," Keren said, nodding her approval of the plan. Her cheeks were white as paper but she got up and walked unsteadily from the room.
"The liquid brought her back from the grave," Norman whispered to Dorothy, watching Keren walk up the hall.
Keren returned immediately, and gave Norman the glass-cutter, which was an instrument shaped like a small riveting hammer. "One promise," she asked. "Sade's mine. I'll be in the tower. You've got to save him for me."

At the glass cage again, it was short work to cut a narrow door at the base of the smooth wall. With an eye on the horizon, Norman quickly covered the cutter with gravel, then motioned Dorothy into the invisible enclosure that had been their prison and so nearly their mausoleum. "We'll play dead," he explained, stretching out on the gravel with the two rifles hidden under him. Dorothy lay down beside him. "When they leave the ship and come over here, I'll jump out. You stay inside in case they get a chance to shoot back."
Suddenly the air hummed with the flow of rockets. "Here they are!" But the sound told Norman that his job was doubled in danger. There were two ships now, the other, his own. They'd repaired it.
Rockets idling, they hovered over the field and slowly settled. Sade's group was now split in two parties—he couldn't surprise them both....
