Murgatroyd came timidly to the door of his cubbyhole. He blinked imploringly at Calhoun. At a repeated command he came unhappily to his master. Calhoun petted him. Then he opened the chest in which a container held living scavengers which writhed and swam and seemed to seethe. He took out that container. He took off the lid.

Murgatroyd backed away. His expression was ludicrous. There was no question but that his nose was grievously offended. Calhoun turned to the grid operator. He extended the sample of scavengers. The grid man clenched his teeth and took it. Then his face worked. He thrust it back into Calhoun's hand.

"It's—horrible!" he said thickly. "Horrible!" Then his jaw dropped. "I'm not a para! Not ... a para—" Then he said fiercely. "We've got to get this thing started! We've got to start curing paras—"

"Who," said Calhoun, "will be ashamed of what they remember. We can't get co-operation form them! And we can't get co-operation from the government! The men who were the government are paras and they've given their authority to Dr. Lett. You don't think he'll abdicate, do you? Especially when it's realized that he was the man who developed the strain of scavengers that secrete this modified butyl mercaptan that turns men into paras!"

Calhoun grinned almost hysterically.

"Maybe it was an accident. Maybe he found himself the first para and was completely astonished. But he couldn't be alone in what he knew was—degradation. He wanted others with him in that ghastly state. He got them. Then he didn't want anybody not to be like himself.... We can't get help from him!"

Exultantly, he flipped switches to show on vision screens what went on in the world outside the ship. He turned on all the receivers that could pick up sounds and broadcasts. Voices came in:

"There's fighting everywhere! Normals won't accept paras among them! Paras won't leave normals alone.... They touch them; breathe on them—and laugh! There's fighting—" The notion that the para state was contagious was still cherished by paras. It was to be preferred to the notion that they were possessed by devils. But there were some who gloried in the more dramatic opinion. There were screamings on the air, suddenly, and a man's voice panting: "Send police here fast! The paras have gone wild. They're—"

Calhoun seated himself at the control desk. He threw switches there. He momentarily touched a button. There was a slight shock and the beginning of a roar outside. It cut off. Calhoun looked at the vision plates showing outside. There was swirling smoke and steam. There were men running in headlong flight, leaving their ground cars behind them.
