Birek looked them over. "The man who refuses will have no neck to save," he said.

There was no disagreement.

MacVickers turned to the leaden cylinder. It was fixed to the duct by a plastic-lined, lead-sheathed collar. There was an arrangement whereby a plug could be driven into the open mouth of the filled cylinder without spilling a grain of the stuff.

MacVickers reached up and loosed the apparatus that held the cylinder upright. It fell over with a shattering crash. A palely glowing powder puffed out, settling over the adjacent metal.

MacVickers had one second of terror. An eerie bluish light grew, throwing faces into strong relief. Pendleton, praying silently. Loris, smiling. The blue-sheathed Earthman with closed eyes, his face a mask of peace. The others, facing a death they understood and welcomed. All of them, thinking of three little worlds that could go on living their own lives.

Birek grinned at him. "I'm glad you ran away," he whispered.

MacVickers grinned back.
