"I've got to do some work on the para condition," Calhoun told him. "I need to be undisturbed in the ship, and I need a patient further along toward being a para than I am. It'll save time. If you'll help, we may be able to beat the thing. If not, I've still got to disable the grid."

The grid operator said in a savage, unhuman voice:

"I'm a para. I'm trying to spray everything I've touched. Then I'm going to go off somewhere and kill myself—"

Calhoun drew his blaster. He adjusted it again to non-lethal intensity.

"Good man!" he said approvingly. "I'll have a similar job to do if I'm not a better medical man than Lett! Will you help me?"

Murgatroyd sneezed again. He said plaintively:

"Chee!"

The grid's operator looked down at him, obviously in a state of shock. No ordinary sight or sound could have gotten through to his consciousness. But Murgatroyd was a small, furry animal with long whiskers and a hirsute tail and a habit of imitating the actions of humans. He sneezed yet again and looked up. There was a handkerchief in Calhoun's pocket. Murgatroyd dragged it out and held it to his face. He sneezed once more and said, "Chee!" and returned the handkerchief to its place. He regarded the grid operator disapprovingly. The operator was shocked out of his despair. He said shakenly:

"What the devil—" Then he stared at Calhoun. "Help you? How can I help anybody? I'm a para!"
