“He said he’d do it. I was a little surprised myself, but apparently he means it. We’ve already made arrangements for his admission to the hospital. His lawyer is drawing up the statement of liability.”
Kramer only half heard. He nodded wearily. “All right. I’m glad. I suppose we can go ahead, then.”
“You don’t sound very glad.”
“I wonder why he decided to go ahead with it.”
“He was very certain about it.” Gross sounded pleased. “He called me quite early. I was still in bed. You know, this calls for a celebration.”
“Sure,” Kramer said. “It sure does.”
Toward the middle of August the project neared completion. They stood outside in the hot autumn heat, looking up at the sleek metal sides of the ship.
Gross thumped the metal with his hand. “Well, it won’t be long. We can begin the test any time.”
“Tell us more about this,” an officer in gold braid said. “It’s such an unusual concept.”
“Is there really a human brain inside the ship?” a dignitary asked, a small man in a rumpled suit. “And the brain is actually alive?”
“Gentlemen, this ship is guided by a living brain instead of the usual Johnson relay-control system. But the brain is not conscious. It will function by reflex only. The practical difference between it and the Johnson system is this: a human brain is far more intricate than any man-made structure, and its ability to adapt itself to a situation, to respond to danger, is far beyond anything that could be artificially built.”
Gross paused, cocking his ear. The turbines of the ship were beginning to rumble, shaking the ground under them with a deep vibration. Kramer was standing a short distance away from the others, his arms folded, watching silently. At the sound of the turbines he walked quickly around the ship to the other side. A few workmen were clearing away the last of the waste, the scraps of wiring and scaffolding. They glanced up at him and went on hurriedly with their work. Kramer mounted the ramp and entered the control cabin of the ship. Winter was sitting at the controls with a Pilot from Space-transport.
“How’s it look?” Kramer asked.
“All right.” Winter got up. “He tells me that it would be best to take off manually. The robot controls—” Winter hesitated. “I mean, the built-in controls, can take over later on in space.”
“That’s right,” the Pilot said. “It’s customary with the Johnson system, and so in this case we should—”
“Can you tell anything yet?” Kramer asked.
“No,” the Pilot said slowly. “I don’t think so. I’ve been going over everything. It seems to be in good order. There’s only one thing I wanted to ask you about.” He put his hand on the control board. “There are some changes here I don’t understand.”
“Changes?”
“Alterations from the original design. I wonder what the purpose is.”
Kramer took a set of the plans from his coat. “Let me look.” He turned the pages over. The Pilot watched carefully over his shoulder.
“The changes aren’t indicated on your copy,” the Pilot said. “I wonder—” He stopped. Commander Gross had entered the control cabin.
“Gross, who authorized alterations?” Kramer said. “Some of the wiring has been changed.”
“Why, your old friend.” Gross signaled to the field tower through the window.
“My old friend?”
“The Professor. He took quite an active interest.” Gross turned to the Pilot. “Let’s get going. We have to take this out past gravity for the test they tell me. Well, perhaps it’s for the best. Are you ready?”
“Sure.” The Pilot sat down and moved some of the controls around. “Anytime.”
“Go ahead, then,” Gross said.
“The Professor—” Kramer began, but at that moment there was a tremendous roar and the ship leaped under him. He grasped one of the wall holds and hung on as best he could. The cabin was filling with a steady throbbing, the raging of the jet turbines underneath them.
The ship leaped. Kramer closed his eyes and held his breath. They were moving out into space, gaining speed each moment.
“Well, what do you think?” Winter said nervously. “Is it time yet?”
“A little longer,” Kramer said. He was sitting on the floor of the cabin, down by the control wiring. He had removed the metal covering-plate, exposing the complicated maze of relay wiring. He was studying it, comparing it to the wiring diagrams.
“What’s the matter?” Gross said.
“These changes. I can’t figure out what they’re for. The only pattern I can make out is that for some reason—”
“Let me look,” the Pilot said. He squatted down beside Kramer. “You were saying?”
“See this lead here? Originally it was switch controlled. It closed and opened automatically, according to temperature change. Now it’s wired so that the central control system operates it. The same with the others. A lot of this was still mechanical, worked by pressure, temperature, stress. Now it’s under the central master.”
“The brain?” Gross said. “You mean it’s been altered so that the brain manipulates it?”
Kramer nodded. “Maybe Professor Thomas felt that no mechanical relays could be trusted. Maybe he thought that things would be happening too fast. But some of these could close in a split second. The brake rockets could go on as quickly as—”
“Hey,” Winter said from the control seat. “We’re getting near the moon stations. What’ll I do?”
They looked out the port. The corroded surface of the moon gleamed up at them, a corrupt and sickening sight. They were moving swift toward it.
“I’ll take it,” the Pilot said. He eased Winter out of the way and strapped himself in place. The ship began to move away from the moon as he manipulated the controls. Down below them they could see the observation stations dotting the surface, and the tiny squares that were the openings of the underground factories and hangars. A red blinker winked up at them and the Pilot’s fingers moved on the board in answer.
“We’re past the moon,” the Pilot said, after a time. The moon had fallen behind them; the ship was heading into outer space. “Well, we can go ahead with it.”
Kramer did not answer.
“Mr. Kramer, we can go ahead any time.”
Kramer started. “Sorry. I was thinking. All right, thanks.” He frowned, deep in thought.
“What is it?” Gross asked.
“The wiring changes. Did you understand the reason for them when you gave the okay to the workmen?”
Gross flushed. “You know I know nothing about technical material. I’m in Security.”
“Then you should have consulted me.”
“What does it matter?” Gross grinned wryly. “We’re going to have to start putting our faith in the old man sooner or later.”
The Pilot stepped back from the board. His face was pale and set. “Well, it’s done,” he said. “That’s it.”
“What’s done?” Kramer said.
“We’re on automatic. The brain. I turned the board over to it—to him, I mean. The Old Man.” The Pilot lit a cigarette and puffed nervously. “Let’s keep our fingers crossed.”
The ship was coasting evenly, in the hands of its invisible pilot. Far down inside the ship, carefully armored and protected, a soft human brain lay in a tank of liquid, a thousand minute electric charges playing over its surface. As the charges rose they were picked up and amplified, fed into relay systems, advanced, carried on through the entire ship—
Gross wiped his forehead nervously. “So he is running it, now. I hope he knows what he’s doing.”
Kramer nodded enigmatically. “I think he does.”
“What do you mean?”
“Nothing.” Kramer walked to the port. “I see we’re still moving in a straight line.” He picked up the microphone. “We can instruct the brain orally, through this.” He blew against the microphone experimentally.
“Go on,” Win
ter said.
“Bring the ship around half-right,” Kramer said. “Decrease speed.”
They waited. Time passed. Gross looked at Kramer. “No change. Nothing.”
“Wait.”
Slowly, the ship was beginning to turn. The turbines missed, reducing their steady beat. The ship was taking up its new course, adjusting itself. Nearby some space debris rushed past, incinerating in the blasts of the turbine jets.
“So far so good,” Gross said.
They began to breathe more easily. The invisible pilot had taken control smoothly, calmly. The ship was in good hands. Kramer spoke a few more words into the microphone, and they swung again. Now they were moving back the way they had come, toward the moon.
“Let’s see what he does when we enter the moon’s pull,” Kramer said. “He was a good mathematician, the old man. He could handle any kind of problem.”
The ship veered, turning away from the moon. The great eaten-away globe fell behind them.
Gross breathed a sigh of relief. “That’s that.”
“One more thing.” Kramer picked up the microphone. “Return to the moon and land the ship at the first space field,” he said into it.
“Good Lord,” Winter murmured. “Why are you—”
“Be quiet.” Kramer stood, listening. The turbines gasped and roared as the ship swung full around, gaining speed. They were moving back, back toward the moon again. The ship dipped down, heading toward the great globe below.
“We’re going a little fast,” the Pilot said. “I don’t see how he can put down at this velocity.”
The port filled up, as the globe swelled rapidly. The Pilot hurried toward the board, reaching for the controls. All at once the ship jerked. The nose lifted and the ship shot out into space, away from the moon, turning at an oblique angle. The men were thrown to the floor by the sudden change in course. They got to their feet again, speechless, staring at each other.
The Pilot gazed down at the board. “It wasn’t me! I didn’t touch a thing. I didn’t even get to it.”
The ship was gaining speed each moment. Kramer hesitated. “Maybe you better switch it back to manual.”
The Pilot closed the switch. He took hold of the steering controls and moved them experimentally. “Nothing.” He turned around. “Nothing. It doesn’t respond.”
No one spoke.
“You can see what has happened,” Kramer said calmly. “The old man won’t let go of it, now that he has it. I was afraid of this when I saw the wiring changes. Everything in this ship is centrally controlled, even the cooling system, the hatches, the garbage release. We’re helpless.”
“Nonsense.” Gross strode to the board. He took hold of the wheel and turned it. The ship continued on its course, moving away from the moon, leaving it behind.
“Release!” Kramer said into the microphone. “Let go of the controls! We’ll take it back. Release.”
“No good,” the Pilot said. “Nothing.” He spun the useless wheel. “It’s dead, completely dead.”
“And we’re still heading out,” Winter said, grinning foolishly. “We’ll be going through the first-line defense belt in a few minutes. If they don’t shoot us down—”
“We better radio back.” The Pilot clicked the radio to send. “I’ll contact the main bases, one of the observation stations.”
“Better get the defense belt, at the speed we’re going. We’ll be into it in a minute.”
“And after that,” Kramer said, “we’ll be in outer space. He’s moving us toward outspace velocity. Is this ship equipped with baths?”
“Baths?” Gross said.
“The sleep tanks. For space-drive. We may need them if we go much faster.”
“But good God, where are we going?” Gross said. “Where—where’s he taking us?”
The Pilot obtained contact. “This is Dwight, on ship,” he said. “We’re entering the defense zone at high velocity. Don’t fire on us.”
“Turn back,” the impersonal voice came through the speaker. “You’re not allowed in the defense zone.”
“We can’t. We’ve lost control.”
“Lost control?”
“This is an experimental ship.”
Gross took the radio. “This is Commander Gross, Security. We’re being carried into outer space. There’s nothing we can do. Is there any way that we can be removed from this ship?”
A hesitation. “We have some fast pursuit ships that could pick you up if you wanted to jump. The chances are good they’d find you. Do you have space flares?”
“We do,” the Pilot said. “Let’s try it.”
“Abandon ship?” Kramer said. “If we leave now we’ll never see it again.”
“What else can we do? We’re gaining speed all the time. Do you propose that we stay here?”
“No.” Kramer shook his head. “Damn it, there ought to be a better solution.”
“Could you contact him?” Winter asked. “The Old Man? Try to reason with him?”
“It’s worth a chance,” Gross said. “Try it.”
“All right.” Kramer took the microphone. He paused a moment. “Listen! Can you hear me? This is Phil Kramer. Can you hear me, Professor. Can you hear me? I want you to release the controls.”
There was silence.
“This is Kramer, Professor. Can you hear me? Do you remember who I am? Do you understand who this is?”
Above the control panel the wall speaker made a sound, a sputtering static. They looked up.
“Can you hear me, Professor. This is Philip Kramer. I want you to give the ship back to us. If you can hear me, release the controls! Let go, Professor. Let go!”
Static. A rushing sound, like the wind. They gazed at each other. There was silence for a moment.
“It’s a waste of time,” Gross said.
“No—listen!”
The sputter came again. Then, mixed with the sputter, almost lost in it, a voice came, toneless, without inflection, a mechanical, lifeless voice from the metal speaker in the wall, above their heads.
“… Is it you, Philip? I can’t make you out. Darkness…. Who’s there? With you….”
“It’s me, Kramer.” His fingers tightened against the microphone handle. “You must release the controls, Professor. We have to get back to Terra. You must.”
Silence. Then the faint, faltering voice came again, a little stronger than before. “Kramer. Everything so strange. I was right, though. Consciousness result of thinking. Necessary result. Cognito ergo sum. Retain conceptual ability. Can you hear me?”
“Yes, Professor—”
“I altered the wiring. Control. I was fairly certain…. I wonder if I can do it. Try….”
Suddenly the air-conditioning snapped into operation. It snapped abruptly off again. Down the corridor a door slammed. Something thudded. The men stood listening. Sounds came from all sides of them, switches shutting, opening. The lights blinked off; they were in darkness. The lights came back on, and at the same time the heating coils dimmed and faded.
“Good God!” Winter said.
Water poured down on them, the emergency fire-fighting system. There was a screaming rush of air. One of the escape hatches had slid back, and the air was roaring frantically out into space.
The hatch banged closed. The ship subsided into silence. The heating coils glowed into life. As suddenly as it had begun the weird exhibition ceased.
“I can do—everything,” the dry, toneless voice came from the wall speaker. “It is all controlled. Kramer, I wish to talk to you. I’ve been—been thinking. I haven’t seen you in many years. A lot to discuss. You’ve changed, boy. We have much to discuss. Your wife--“
The Pilot grabbed Kramer’s arm. “There’s a ship standing off our bow. Look.”
They ran to the port. A slender pale craft was moving along with them, keeping pace with them. It was signal-blinking.
“A Terran pursuit ship,” the Pilot said. “Let’s jump. They’ll pick us up. Suits—”
/>
He ran to a supply cupboard and turned the handle. The door opened and he pulled the suits out onto the floor.
“Hurry,” Gross said. A panic seized them. They dressed frantically, pulling the heavy garments over them. Winter staggered to the escape hatch and stood by it, waiting for the others. They joined him, one by one.
“Let’s go!” Gross said. “Open the hatch.”
Winter tugged at the hatch. “Help me.”
They grabbed hold, tugging together. Nothing happened. The hatch refused to budge.
“Get a crowbar,” the Pilot said.
“Hasn’t anyone got a blaster?” Gross looked frantically around. “Damn it, blast it open!”
“Pull,” Kramer grated. “Pull together.”
“Are you at the hatch?” the toneless voice came, drifting and eddying through the corridors of the ship. They looked up, staring around them. “I sense something nearby, outside. A ship? You are leaving, all of you? Kramer, you are leaving, too? Very unfortunate. I had hoped we could talk. Perhaps at some other time you might be induced to remain.”
“Open the hatch!” Kramer said, staring up at the impersonal walls of the ship. “For God’s sake, open it!”
There was silence, an endless pause. Then, very slowly, the hatch slid back. The air screamed out, rushing past them into space.
One by one they leaped, one after the other, propelled away by the repulsive material of the suits. A few minutes later they were being hauled aboard the pursuit ship. As the last one of them was lifted through the port, their own ship pointed itself suddenly upward and shot off at tremendous speed. It disappeared.
Kramer removed his helmet, gasping. Two sailors held onto him and began to wrap him in blankets. Gross sipped a mug of coffee, shivering.
“It’s gone,” Kramer murmured.
“I’ll have an alarm sent out,” Gross said.
“What’s happened to your ship?” a sailor asked curiously. “It sure took off in a hurry. Who’s on it?”
“We’ll have to have it destroyed,” Gross went on, his face grim. “It’s got to be destroyed. There’s no telling what it—what he has in mind.” Gross sat down weakly on a metal bench. “What a close call for us. We were so damn trusting.”
