Inwardly he was chagrined. He and the crazies had searched for every possible surviving member of Helicon. Compared experiences and his body-count suggested that very few were unaccounted for. Was the intruder from outside? Most of the tribesmen were terrified of this region, and would never enter the mountain even if they could find their way in.
Of course Tyl and his army had forced entry here during the conquest of the mountain, so those men could penetrate Helicon again if they chose. But Neq had sealed over the invasion apertures as well as he could and none of them seemed to have been reopened, and no damage had been done.
Someone had come without fear, looked about, had a bite to eat, and departed. That person could come again.
CHAPTER NINETEEN
"Yes, she is pregnant," Dick the Surgeon said. "I think under the circumstances she should be excused from, er, circulation. Our children will be our most important asset for some time, for they will be raised in the atmosphere of civilization...."
It was Neq's decision to make, and it would set a precedent, but he was aware of his own bias. Intellectually he knew that the women had to be shared; emotionally he couldn't share Vara. "It's a matter of health," he said. "That's your department."
So Vara did not circulate. Actually the system had not been fully implemented yet; people needed time to settle in to it. There was some problem about the women's arrangements, for they required more privacy than the men's rooms provided, sexual aspects aside. Finally they were assigned rooms of their own, but were expected to make their rounds on schedule.
If the social system functioned with hesitation, at least the reconstruction didn't. The restoration of electric power was much simpler than anticipated. A few cables replaced, a few circuit-breakers closed, a few fixtures tinkered with, a few parts substituted, and there was light and heat and circulating air and sanitary facilities in operation. Helicon had been beautifully designed; they were not building or even rebuilding it. They were merely implementing a system that had been temporarily interrupted.
In a month they were ready to tackle the peripheral machinery: the subway to the hostel, the manufacturing machines. In two months the first weapons were produced: quarterstaffs cut from an endless metal pole extruded from an automatic smelter-processor. There was ore from the monstrous metallic refuse of the mountain--enough for a century's such operations.
Neq realized with a certain surprise that it was working! Helicon was coming back to life, beginning to function again. That simple, significant success had almost been obscured behind the minutiae of daily projects and crises! Actually, Helicon was an entity in itself, performing on its own fashion; the hiatus of years and the change of personnel seemed almost irrelevant to its giant personality.
The signal alarm woke Neq during the night cycle. Night was artificial here, as was day, but they maintained the same rhythm as above. The recently renovated television screen was on.
"We've netted something," Jim the Gun said tersely. "It didn't pass through any of the entrances we know, but it's inside now. I thought you'd want to be on hand."
"Yest" Neq shrugged into his special open-sleeve robe and hurried through the half-lighted halls to Jim's laboratory. He remembered the mysterious visitor. Had he come again?
"I thought it was one of the fringe beasts," Jim said.
"They keep finding new places...." Neq knew what he meant. There were strange creatures in the radiation-soaked outer tunnels of the mountain--mutation-spawned monsters who had shaped their own grotesque ecology. Helicon proper had been sealed off from such sections, but the seal was imperfect, and sometimes rodents and amphibians got through. Once a dead toothy froglike thing had popped out of a flush toilet, and Jim had had to trace the sewer pipes to discover the entry point. It had been hopeless; Helicon's water came from a vast subterranean conduit and departed the same way after passing through a waste-recycling plant. It was too complex to unravel, and dangerous to tamper with, for the water was "hot-- so hot that live steam burst periodically from vents and filled the maintenance passages. Jim had had to settle for a filter in the main drinking-water pipe. Sometimes eerie noises penetrated the walls, as of alien creatures hunting or struggling. The increasing hum of functioning machinery drowned much of this out, and that was a blessing. It was too easy for the nomads to believe in haunts--since, of course, there were haunts.
Jim had rigged an alarm system designed to spot the emergence of any such creatures, so that the holes could be located and plugged. "It's a big one this time," he said, leading Neq to a storeroom as yet unused. The back wall here seemed solid, but Jim had traced skuff-marks in the dust of the floor to a removable panel constructed to resemble stone. "Human or near-human, obviously," Jim said. "He came in from the other side--it seems to be a half-collapsed tunnel with some radiation--and pushed out the panel, then replaced it perfectly. Then on through the room and out to the hall--which is where he tripped my electric-eye system. He was gone by the time I got here, of course--but at least we know how he did it."
Neq felt the chill again. "But he's inside Helicon--right now!" Had he come for beans again--or something more?
Jim nodded. "He passed the eye half an hour ago. I can't tell from the signal whether it's a mouse or an elephant--uh, that's an extremely large animal that existed before the Blast. Elephant. I get several of these each night--"
"The Elephants?"
"Alarms. And I don't know anything until I check personally. Half the time it's one of our own personnel, on some unscheduled business. Or a couple of them. Quite a bit of out-of-turn trysting in these back rooms, you know. I have to be very cautious about checking. The girls share, but they want to get pregnant by particular men..."
Neq knew. He had never cracked down on it because he felt the same way himself. It was his baby Vara carried, whatever name it was to bear.
"So we're late starting, but we can run him down. Block off this exit and flood the halls with flower-narcotic--"
Neq didn't like it. "There are people going about," he pointed out. "We keep a limited night shift going now, and some are on the machines. A whiff of the flower, and equipment could be wrecked. The amount that gets around by accident is bad enough! No, we'll do it by hand. How could a stranger come, and not be seen?"
"He would have to know Helicon," Jim said. "Where to hide, where to step aside--"
"And how to bluff his way through when he did meet people," Neq said. "That makes him dangerous. We don't know his motive."
"It has to be a former member of Helicon," Jim said. "One of our retreads should be able to recognize him?"
"Helicon is open to the old members. Why hasn't he contacted us?"
"Maybe he's trying to."
"All he has to do is yell or bang on the wall."
"Let's go to my lab," Jim said. "If he keeps ducking out of sight, he'll have to trip other alarms."
They were in luck. The intruder tripped several alarms, ducking out of the way as others used the hall. Jim kept no eye-beams set in the main passages, since that would lead to hopeless confusion. It was coincidental, but his emplacements were ideally suited to this type of chase.
"He's going somewhere," Jim said. "See that pattern. I think he's literate--a couple of those dodges were near the dining room bulletin board. Now he knows what he wants. When we figure it out too, we'll be able to intercept him. Catch him by surprise, so he can't hurt anyone."
"Toward the sleeping quarters!" Neq exclaimed, looking at the chart of Helicon on which Jim had set his markers.
