He forced his thoughts back to the Med Ship when it was twenty miles high, and ten, and five. He'd watched the ground through the electron telescope and he had a mental picture of the city from the sky. It was as clear to him as a map. He could orient himself. He could tell where he was.
A ground car came to a stop some distance ahead. A man got out, his arms full of bundles which would be food. Calhoun broke into a run. The man tried to get inside the doorway before Calhoun could arrive. But he would not leave any of the food.
Calhoun showed his blaster.
"I'm a para," he said quietly, "and I want this car. Give me the keys and you can keep the food."
The man groaned. Then he dropped the keys on the ground. He fled into the house.
"Thanks," said Calhoun politely to the emptiness.
He took his place in the car. He thrust Murgatroyd again out of sight.
"It's not," he told the tormal with a sort of despairing humor, "that I'm ashamed of you, Murgatroyd, but I'm afraid I may become ashamed of myself. Keep low!"
He started the car and drove away.
He passed through a business district, with many smashed windows. He passed through canyons formed by office buildings. He crossed a manufacturing area, in which there were many ungainly factories but no sign of any work going on. In any epidemic many men stay home from work to avoid contagion. On Tallien Three nobody would be willing to risk employment, for fear of losing much more than his life.
There there was a wide straight highway leading away from the city but not toward the spaceport. Calhoun drove his stolen car along it. He saw the strange steel embroidery of the landing grid rising to the height of a minor mountain against the sky. He drove furiously. Beyond it. He had seen the highway system from twenty miles height, and ten, and five. From somewhere near here stolen weather rockets had gone billowing skyward with explosive war heads to shatter Esclipus Twenty.
They'd failed. Now Calhoun went past the place from which they had been launched, and did not notice. Once he could look across flat fields and see the spaceport highway. It was empty. Then there was sunset. He saw the topmost silvery beams and girders of the landing grid still glowing in sunshine which no longer reached down to the planet's solid ground.
He drove. And drove. Government Center might put a road block to the spaceport, just in case. But they'd really believe him still hiding somewhere in Government Center with no hope of—actually—accomplishing anything but his own destruction.
After sunset he was miles beyond the spaceport. When twilight was done, he'd crossed to another surface road and was headed back toward the city. But this time he would pass close to the spaceport. And two hours after sundown he turned the car's running-lights off and drove a dark and nearly noiseless vehicle through deep-fallen night. Even so, he left the ground car a mile from the tall and looming lacework of steel. He listened with straining ears for a long time.
Presently he and Murgatroyd approached the spaceport, on foot, from a rather improbable direction. The gigantic, unsubstantiated tower rose incredibly far toward the sky. As he drew near it he crouched lower and lower so he was almost crawling to keep from being silhouetted against the stars. He saw lights in the windows of the grid's control building. As he looked, a lighted window darkened from someone moving past it inside. There was an enormous stillness, broken only by faint, faint noises of the wind in the metal skeleton.
He saw no ground cars to indicate men brought here and waiting for him. He went very cautiously forward. Once he stopped and distastefully restored his blaster to lethal-charge intensity. If he had to use it, he couldn't hope to shoot accurately enough to stun an antagonist. He'd have to fight for his life—or rather, for the chance to live as a normal man, and to restore that possibility to the people in the ghastly-quiet city at the horizon and the other lesser cities elsewhere on this world.
He took infinite precautions. He saw the Med Ship standing valiantly upright on its landing fins. It was a relief to see it. The grid operator could have been ordered to lift it out to space—thrown away to nowhere, or put in orbit until it was wanted again, or....
That was still a possibility. Calhoun's expression turned wry. He'd have to do something about the grid. He must be able to take off on the ship's emergency rockets without the risk of being caught by the tremendously powerful force fields by which ships were launched and landed.
He crept close to the control building. No voices, but there was movement inside. Presently he peered in a window.
The grid operator who'd been the first man to greet him on his landing, now moved about the interior of the building. He pushed a tank on wheels. With a hose attached to it, he sprayed. Mist poured out and splashed away from the side walls. It hung in the air and settled on the desks, the chairs, and on the control board with its dials and switches. Calhoun had seen the mist before. It had been used to spray instead of burning the bodies of the two men who'd tried to murder him, and their wrecked ground car, and everywhere that the car was known to have run. It was a decontaminant spray; credited with the ability to destroy the contagion that made paras out of men.
Calhoun saw the grid operator's face. It was resolute beyond expression, but it was very, very bitter.
Calhoun went confidently to the door and knocked on it. A savage voice inside said:
"Go away! I just found out I'm a para!"
Calhoun opened the door and walked inside. Murgatroyd followed. He sneezed as the mist reached his nostrils.
"Ive been treated," said Calhoun, "so I'll be a para right along with you, after whatever the development period is. Question: Can you fix the controls so nobody else can use the grid?"
The grid operator stared at him numbly. He was deathly pale. He did not seem able to grasp what Calhoun had said.
"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!"
"Which," said Calhoun, "is just what I need. I'm Med Service, man! I've got a job to do with what they call an epidemic! I need a para who's willing to be cured! That's you! Let's get this grid fixed so it can't work and—"
