The Invincible

videoscreen. “I’ve already given the all-clear signal,” he said calmly. “It’s only raining. Look here, Rohan, what a beautiful sight!”

Indeed, a spray of innumerable sparks covered the videoscreen, which showed the upper part of the nocturnal sky. Raindrops were falling from a great height, spattering against the invisible protective shield of the energy field that surrounded the Invincible like an overturned bowl. Upon impact the drops of water instantaneously changed into microscopic fiery explosions, bathing the whole landscape with glittering light that resembled a hundredfold intensified display of the Northern Lights.

“The automats should have been better programed,” said Rohan softly. He felt wide awake now. “I have to tell Terner to eliminate the instructions for annihilation. Otherwise every handful of sand that comes drifting against the energy dome will jerk us out of our sleep.”

“Let’s assume this was nothing but a fire drill,” replied the astrogator, who seemed to be in an unexpectedly good mood. “It’s four o’clock in the morning now. You can go back to sleep, Rohan.”

“To be frank with you, I don’t feel in the least bit like it. How about you?”

“I’m not sleepy at all. All I ever need is four hours of rest. After sixteen years of space travel not much has remained from the sleeping pattern I used to have back on Earth. Rohan, I’ve been trying to figure out the maximum security for our search troops. It’s too cumbersome for them to drag energo-robots along everywhere they go in order to set up protective screens. What do you think about that?”

“Why not send along a personal emitter for each member of the group? No, that wouldn’t do the trick either. You can’t touch anything if you’re surrounded by the protective bubble — you know what that’s like. And if you shorten the field radius too much, you risk nasty burns. I’ve been through that before.”

“I’ve even considered not sending any men out at all, but using remote-controlled robots instead,” confessed Horpach. “Of course that would only work for a few hours, or one day at best. But I believe we are going to stay here for a while.”

“What are your plans?”

“Each research team will have a base of operations, protected by an energy field. But there must be a certain freedom of mobility, otherwise we won’t obtain any useful results because of all the protective measures. But only under one condition: any man who works outside the protective screen must have a shielded companion immediately behind who will observe him. You must never lose sight of anyone under any circumstance; that is absolute law for our stay on Regis III.”

“Which group will I be assigned to?”

“Would you like to work at the Condor? Or would you rather explore the desert or the ‘city’? It’s up to you.”

“I’ll take the ‘city,’ astrogator. I still think that’s where we will find the solution to this mystery.”

“Possibly. Tomorrow — no, today, the sun’s coming up already — you will take the same group of men who accompanied you yesterday. I’ll send along a few Arctanes. Several hand laser weapons wouldn’t be a bad idea either. I have the impression that it is effective from a short range.”

“What do you mean by ‘it’?”

“If only I knew. Well, don’t forget to take along a field kitchen. You’ll want to be completely independent so you can carry on without having to count on supplies from the spaceship.”

The red disk of the sun hardly supplied any heat as it rolled across the firmament, the shadows of the grotesque structures grew longer and fused. The wind whirled the wander dunes between the metal pyramids from place to place. Standing on the roof of a heavy caterpillar truck, Rohan peered through his field glasses and observed Gralew and Chen, who were busy outside the protective screen investigating something at the foot of one of the black honey-combs. His portable searchlight hung from a strap around his neck. The strap cut uncomfortably into his skin. Without ever letting the two men out of his sight, he tried to adjust the strap, pulling it away from his neck. The plasma burner in Chen’s hand was sparkling like a tiny diamond. From inside the truck came a radio signal, calling at regular intervals. Rohan did not turn his head. He heard the driver answer the call.

“Navigator! Orders from the astrogator! We’re to return at once!” yelled Jarg excitedly and stuck his head out of the turret hatch.

“Did you say return? Why?”

“I don’t know. They’ve been sending the return signal constantly — EV four times already.”

“EV? Damn it, my neck feels stiff! All right, let’s get a move on. Give me that microphone and get out the blinker signals.”

Ten minutes later all the men who had been working in the outer zone were back inside the vehicles. Rohan urged his small column to hurry as fast as it could over the hilly terrain. Blank, functioning now as wireless operator, suddenly held out the earphones to him. Rohan climbed down into the steel belly of the vehicle, where it smelled of hot plastic. Over the humming of the ventilators, whose air blasts ruffled up his hair, he listened in to the exchange of radio messages between Gallagher’s group in the western desert and the Invincible.

A thunderstorm seemed to be brewing. Ever since that morning the barometers had indicated low air pressure, but not until this moment did flat, dark blue clouds creep up on the horizon. High above was the clear sky. The atmospheric disturbance kept increasing, until the static noise grew so strong in the earphones that communication could take place only by Morse Code signals.

Rohan intercepted a group of coded messages. He had come in on the middle of the transmission, however, and did not grasp what it was all about. He only understood that Gallagher’s group was also returning at top speed and that a red alert had been called on the Invincible. Even the physicians had been ordered to man their stations.

“Alert for the physicians,” Rohan said to Ballmin and Gralew, who looked at him expectantly. “An accident, but surely nothing serious. Maybe there was a landslide somewhere and someone was buried under it for a while.”

He mentioned this because he had been told that Gallagher’s men were supposed to scout a certain area and make geological excavations there. But in his heart he did not really believe that it was a matter of an ordinary accident.

They were less than four miles from the spaceship, but the other group evidently had been called back much earlier, for when they sighted the steep dark silhouette of the Invincible they came across fresh tracks made by the caterpillar drive vehicles. The impressions in the sand could have been no more than thirty minutes old, otherwise they would have been wiped out by the strong wind.

They approached the perimeter of the energy dome and called the command center to open a pathway for them. They had to wait surprisingly long for an answer. Finally the blue light signals appeared and they were let into the protected area. The group from the Condor had already arrived. Then they and not Gallagher’s people had been admitted inside before them. Several trucks were parked next to the ramp and near the drive entrance; men ran about aimlessly, sinking into the sand up to their knees. Automats blinked with their searchlights.

Dusk was falling. Rohan did not know what to make of this chaotic scene. Suddenly a bright ray of light flared up high, transforming the rocket into a giant lighthouse. Far back in the desert, the searchlights had pinpointed a column of lights that danced crazily back and forth as if an entire military convoy were approaching. Once again the blue lights flared up, marking the entrance to the energy field to let in Gallagher’s party. Hardly had the vehicles come to a stop when the patrol jumped to the ground. A second searchlight rolled down the ramp, and a small procession passed through the narrow lane between the parked tracks, bearing a man on a stretcher.

As they went by Rohan, he pushed past the men in front of him, then stopped in his tracks. For a moment he really believed an accident had taken place, for the man on the litter had been tightly strapped down. He kept struggling against his bonds, and they creaked under the strain. At the same time, a terrible whine rose from his open mouth.

The group continued to follow the path marked by the cone of the kleig light. The procession drew farther and farther away, but he could still hear clearly the nonhuman howling, unlike anything he had ever heard before, as he stood there alone in the dark. The white spot with the figures grew smaller, slid up the ramp and disappeared in the darkly gaping hole of the loading hatch. Rohan called out to some of the men, asking them what had happened, but they did not know any more than he did, since they belonged to the Condor troop.

Quite some time passed before he regained his composure and could find his bearings again. The column of
