The skipper listened in silence.
Jensen said thinly, "Then the story about the landing was true."
"Yes. The authorities isolated her, and then shipped her off on the Star Queen. Your well-informed friends, Jensen, didn't know what their government was going to do!" Nordenfeld paused, and said more coldly still, "They didn't handle it right. They should have killed her, painlessly but at once. Her body should have been immersed, with everything that had touched it, in full-strength nitric acid. The same acid should have saturated the place where the ship landed and every place she walked. Every room she entered, and every hall she passed through, should have been doused with nitric and then burned. It would still not have been all one could wish. The air she breathed couldn't be recaptured and heated white-hot. But the chances for Altaira's population to go on living would be improved. Instead, they isolated her and they shipped her off with us—and thought they were accomplishing something by destroying the lift-ship that had her in an airtight compartment until she walked into the Star Queen's lock!"
The skipper said heavily, "Do you think she's brought chlorophage on board?"
"I've no idea," said Nordenfeld. "If she did, it's too late to do anything but drive the Star Queen into the nearest sun.... No. Before that, one should give warning that she was aground on Altaira. No ship should land there. No ship should take off. Altaira should be blocked off from the rest of the galaxy like Kamerun was. And to the same end result."
Jensen said unsteadily; "There'll be trouble if this is known on the ship. There'll be some unwilling to sacrifice themselves."
"Sacrifice?" said Nordenfeld. "They're dead! But before they lie down, they can keep everybody they care about from dying too! Would you want to land and have your wife and family die of it?"
The skipper said in the same heavy voice, "What are the probabilities? You say there was an effort to keep her from contagion. What are the odds?"
"Bad," said Nordenfeld. "The man tried, for the child's sake. But I doubt he managed to make a completely aseptic transfer from the room she lived in to the spaceport on Altaira. The authorities on Altaira should have known it. They should have killed her and destroyed everything she'd touched. And still the odds would have been bad!"
Jensen said, "But you can't do that, Nordenfeld! Not now!"
