There was a fading memory of a young engineer – even the name escaped him now – who had once aspired to fame and wisdom. In that other life, he had known this foolish person well, but now he could never explain to him the vanity of his ambitions.
He began to wander idly along the beach, the last vague recollections of his shadow life sloughing from him with every footstep, as the details of a dream fade into the light of day.
On the other side of the world three very worried scientists were waiting in a deserted laboratory, their eyes on a multichannel communicator of unusual design. The machine had been silent for nine hours. No one had expected a message in the first eight, but the prearranged signal was now more than an hour overdue.
Alan Henson jumped to his feet with a gesture of impatience.
‘We’ve got to do something! I’m going to call him.’
The other two scientists looked at each other nervously.
‘The call may be traced!’
‘Not unless they’re actually watching us. Even if they are, I’ll say nothing unusual. Peyton will understand, if he can answer at all….’
If Richard Peyton had ever known time, that knowledge was forgotten now. Only the present was real, for both past and future lay hidden behind an impenetrable screen, as a great landscape may be concealed by a driving wall of rain.
In his enjoyment of the present Peyton was utterly content. Nothing at all was left of the restless driving spirit that had once set out, a little uncertainly, to conquer fresh fields of knowledge. He had no use for knowledge now.
Later he was never able to recollect anything of his life on the island. He had known many companions, but their names and faces had vanished beyond recall. Love, peace of mind, happiness – all were his for a brief moment of time. And yet he could remember no more than the last few moments of his life in paradise.
Strange that it should have ended as it began. Once more he was by the side of the lagoon, but this time it was night and he was not alone. The moon that seemed always to be full rode low above the ocean, and its long silver band stretched far away to the edge of the world. The stars that never changed their places glowed unblinking in the sky like brilliant jewels, more glorious than the forgotten stars of Earth.
But Peyton’s thoughts were intent on other beauty, and once again he bent toward the figure lying on the sand that was no more golden than the hair strewn carelessly across it.
Then paradise trembled and dissolved around him. He gave a great cry of anguish as everything he loved was wrenched away. Only the swiftness of the transition saved his mind. When it was over, he felt as Adam must have when the gates of Eden clanged forever shut behind him.
But the sound that had brought him back was the most commonplace in all the world. Perhaps, indeed, no other could have reached his mind in its place of hiding. It was only the shrilling of his communicator set as it lay on the door beside his couch, here in the darkened room in the city of Comarre.
The clangour died away as he reached out automatically to press the receiving switch. He must have made some answer that satisfied his unknown caller – who was Alan Henson? – for after a very short time the circuit was cleared. Still dazed, Peyton sat on the couch, holding his head in his hands and trying to reorient his life.
He had not been dreaming; he was sure of that. Rather, it was as if he had been living a second life and now he was returning to his old existence as might a man recovering from amnesia. Though he was still dazed, one clear conviction came into his mind. He must never again sleep in Comarre.
Slowly the will and character of Richard Peyton III returned from their banishment. Unsteadily he rose to his feet and made his way out of the room. Once again he found himself in the long corridor with its hundreds of identical doors. With new understanding he looked at the symbol carved upon them.
He scarcely noticed where he was going. His mind was fixed too intently on the problem before him. As he walked, his brain cleared, and slowly understanding came. For the moment it was only a theory, but soon he would put it to the test.
The human mind was a delicate, sheltered thing, having no direct contact with the world and gathering all its knowledge and experience through the body’s senses. It was possible to record and store thoughts and emotions as earlier men had once recorded sound on miles of wire.
If those thoughts were projected into another mind, when the body was unconscious and all its senses numbed, that brain would think it was experiencing reality. There was no way in which it could detect the deception, any more than one can distinguish a perfectly recorded symphony from the original performance.
All this had been known for centuries, but the builders of Comarre had used the knowledge as no one in the world had ever done before. Somewhere in the city there must be machines that could analyse every thought and desire of those who entered. Elsewhere the city’s makers must have stored every sensation and experience a human mind could know. From this raw material all possible futures could be constructed.
Now at last Peyton understood the measure of the genius that had gone into the making of Comarre. The machines had analysed his deepest thoughts and built for him a world based on his subconscious desires. Then, when the chance had come, they had taken control of his mind and injected into it all he had experienced.
No wonder that everything he had ever longed for had been his in that already half-forgotten paradise. And no wonder that through the ages so many had sought the peace only Comarre could bring!
CHAPTER FIVE
The Engineer
Peyton had become himself again by the time the sound of wheels made him look over his shoulder. The little robot that had been his guide was returning. No doubt the great machines that controlled it were wondering what had happened to its charge. Peyton waited, a thought slowly forming in his mind.
A-Five started all over again with its set speech. It seemed very incongruous now to find so simple a machine in this place where automatronics had reached their ultimate development. Then Peyton realised that perhaps the robot was deliberately uncomplicated. There was little purpose in using a complex machine where a simple one would serve as well – or better.
Peyton ignored the now familiar speech. All robots, he knew, must obey human commands unless other humans had previously given them orders to the contrary. Even the projectors of the city, he thought wryly, had obeyed the unknown and unspoken commands of his own subconscious mind.
‘Lead me to the thought projectors,’ he commanded.
As he had expected, the robot did not move. It merely replied, ‘I do not understand.’
Peyton’s spirits began to revive as he felt himself once more master of the situation.
‘Come here and do not move again until I give the order.’
The robot’s selectors and relays considered the instructions. They could find no countermanding order. Slowly the little machine rolled forward on its wheels. It had committed itself – there was no turning back now. It could not move again until Peyton ordered it to do so or something overrode his commands. Robot hypnosis was a very old trick, much beloved by mischievous small boys.
Swiftly, Peyton emptied his bag of the tools no engineer was ever without: the universal screw driver, the expanding wrench, the automatic drill, and, most important of all, the atomic cutter that could eat through the thickest metal in a matter of seconds. Then, with a skill born of long practice, he went to work on the unsuspecting machine.
Luckily the robot had been built for easy servicing, and could be opened with little difficulty. There was nothing unfamiliar about the controls, and it did not take Peyton long to find the locomotor mechanism. Now, whatever happened, the machine could not escape. It was crippled.
Next he blinded it and, one by one, tracked down its other electrical senses and put them out of commission. Soon the little machine was no more than a cylinder full of complicated junk. Feeling like a small boy who has just made a wanton attack on a defenceless g
randfather clock, Peyton sat down and waited for what he knew must happen.
It was a little inconsiderate of him to sabotage the robot so far from the main machine levels. The robot-transporter took nearly fifteen minutes to work its way up from the depths. Peyton heard the rumble of its wheels in the distance and knew that his calculations had been correct. The breakdown party was on the way.
The transporter was a simple carrying machine, with a set of arms that could grasp and hold a damaged robot. It seemed to be blind, though no doubt its special senses were quite sufficient for its purpose.
Peyton waited until it had collected the unfortunate A-Five. Then he jumped aboard, keeping well away from the mechanical limbs. He had no desire to be mistaken for another distressed robot. Fortunately the big machine took no notice of him at all.
So Peyton descended through level after level of the great building, past the living quarters, through the room in which he had first found himself, and lower yet into regions he had never before seen. As he descended, the character of the city changed around him.
Gone now were the luxury and opulence of the higher levels, replaced by a no man’s land of bleak passageways that were little more than giant cable ducts. Presently these, too, came to an end. The conveyor passed through a set of great sliding doors – and he had reached his goal.
The rows of relay panels and selector mechanisms seemed endless, but though Peyton was tempted to jump off his unwitting steed, he waited until the main control panels came into sight. Then he climbed off the conveyor and watched it disappear into the distance toward some still more remote part of the city.
He wondered how long it would take the superautomata to repair A-Five. His sabotage had been very thorough, and he rather thought the little machine was heading for the scrap heap. Then, feeling like a starving man suddenly confronted by a banquet, he began his examination of the city’s wonders.
In the next five hours he paused only once to send the routine signal back to his friends. He wished he could tell of his success, but the risk was too great. After prodigies of circuit tracing he had discovered the functions of the main units and was beginning to investigate some of the secondary equipment.
It was just as he had expected. The thought analysers and projectors lay on the floor immediately above, and could be controlled from, this central installation. How they worked he had no conception: it might well take months to uncover all their secrets. But he had identified them and thought he could probably switch them off if necessary.
A little later he discovered the thought monitor. It was a small machine, rather like an ancient manual telephone switchboard, but very much more complex. The operator’s seat was a curious structure, insulated from the ground and roofed by a network of wires and crystal bars. It was the first machine he had discovered that was obviously intended for direct human use. Probably the first engineers had built it to set up the equipment in the early days of the city.
Peyton would not have risked using the thought monitor if detailed instructions had not been printed on its control panel. After some experimenting he plugged in to one of the circuits and slowly increased the power, keeping the intensity control well below the red danger mark.
It was as well that he did so, for the sensation was a shattering one. He still retained his own personality, but superimposed on his own thoughts were ideas and images that were utterly foreign to him. He was looking at another world, through the windows of an alien mind.
It was as though his body were in two places at once, though the sensations of his second personality were much less vivid than those of the real Richard Peyton III. Now he understood the meaning of the danger line. If the thought-intensity control was turned too high, madness would certainly result.
Peyton switched off the instrument so that he could think without interruption. He understood now what the robot had meant when it said that the other inhabitants of the city were sleeping. There were other men in Comarre, lying entranced beneath the thought projectors.
His mind went back to the long corridor and its hundreds of metal doors. On his way down he had passed through many such galleries and it was clear that the greater part of the city was no more than a vast honeycomb of chambers in which thousands of men could dream away their lives.
One after another he checked the circuits on the board. The great majority were dead, but perhaps fifty were still operating. And each of them carried all the thoughts, desires, and emotions of the human mind.
Now that he was fully conscious, Peyton could understand how he had been tricked, but the knowledge brought little consolation. He could see the flaws in these synthetic worlds, could observe how all the critical faculties of the mind were numbed while an endless stream of simple but vivid emotions was poured into it.
Yes, it all seemed very simple now. But it did not alter the fact that this artificial world was utterly real to the beholder – so real that the pain of leaving it still burned in his own mind.
For nearly an hour, Peyton explored the worlds of the fifty sleeping minds. It was a fascinating though repulsive quest. In that hour he learned more of the human brain and its hidden ways than he had ever dreamed existed. When he had finished he sat very still for a long time at the controls of the machine, analysing his new-found knowledge. His wisdom had advanced by many years, and his youth seemed suddenly very far away.
For the first time he had direct knowledge of the fact that the perverse and evil desires that sometimes ruffled the surface of his own mind were shared by all human beings. The builders of Comarre had cared nothing for good or evil – and the machines had been their faithful servants.
It was satisfactory to know that his theories had been correct. Peyton understood now the narrowness of his escape. If he fell asleep again within these walls he might never awake. Chance had saved him once, but it would not do so again.
The thought projectors must be put out of action, so thoroughly that the robots could never repair them. Though they could handle normal breakdowns, the robots could not deal with the deliberate sabotage on the scale Peyton was envisaging. When he had finished, Comarre would be a menace no longer. It would never trap his mind again, or the minds of any future visitors who might come this way.
First he would have to locate the sleepers and revive them. That might be a lengthy task, but fortunately the machine level was equipped with standard monovision search apparatus. With it he could see and hear everything in the city, simply by focusing the carrier beams on the required spot. He could even project his voice if necessary, but not his image. That type of machine had not come into general use until after the building of Comarre.
It took him a little while to master the controls, and at first the beam wandered erratically all over the city. Peyton found himself looking into any number of surprising places, and once he even got a glimpse of the forest – though it was upside down. He wondered if Leo was still around, and with some difficulty he located the entrance.
Yes, there it was, just as he had left it the day before. And a few yards away the faithful Leo was lying with his head toward the city and a distinctly worried look on his face. Peyton was deeply touched. He wondered if he could get the lion into Comarre. The moral support would be valuable, for he was beginning to feel more need of companionship after the night’s experiences.
Methodically he searched the wall of the city and was greatly relieved to discover several concealed entrances at ground level. He had been wondering how he was going to leave. Even if he could work the matter-transmitter in reverse, the prospect was not an attractive one. He much preferred an old-fashioned physical movement through space.
The openings were all sealed, and for a moment he was baffled. Then he began to search for a robot. After some delay, he discovered one of the late A-Five’s twins rolling along a corridor on some mysterious errand. To his relief, it obeyed his command unquestioningly and opened the door.
Peyton drove the beam through the walls again
and brought the focus point to rest a few feet away from Leo. Then he called, softly:
‘Leo!’
The lion looked up, startled.
‘Hello, Leo – it’s me – Peyton!’
Looking puzzled, the lion walked slowly around in a circle. Then it gave up and sat down helplessly.
With a great deal of persuasion, Peyton coaxed Leo up to the entrance. The lion recognised his voice and seemed willing to follow, but it was a sorely puzzled and rather nervous animal. It hesitated for a moment at the opening, liking neither Comarre nor the silently waiting robot.
Very patiently Peyton instructed Leo to follow the robot. He repeated his remarks in different words until he was sure the lion understood. Then he spoke directly to the machine and ordered it to guide the lion to the control chamber. He watched it for a moment to see that Leo was following. Then, with a word of encouragement, he left the strangely assorted pair.
It was rather disappointing to find that he could not see into any of the sealed rooms behind the poppy symbol. They were shielded from the beam or else the focusing controls had been set so that the monovisor could not be used to pry into that volume of space.
Peyton was not discouraged. The sleepers would wake up the hard way, as he had done. Having looked into their private worlds, he felt little sympathy for them and only a sense of duty impelled him to wake them. They deserved no consideration.
A horrible thought suddenly assailed him. What had the projectors fed into his own mind in response to his desires, in that forgotten idyll from which he had been so reluctant to return? Had his own hidden thoughts been as disreputable as those of the other dreamers?
It was an uncomfortable idea, and he put it aside as he sat down once more at the central switchboard. First he would disconnect the circuits, then he would sabotage the projectors so that they could never again be used. The spell that Comarre had cast over so many minds would be broken forever.
