There was silence for some seconds. Then Camhorn's companion observed, "There's one thing that doesn't quite fit in with your theory, lieutenant."
"What's that, sir?"
"Your report states that you switched off your AR field at the same time you advised Miss Trelawney to get out of her suit. You should have been equally subject to the alien's mental instructions."
"Well," Dowland said, "I can attempt to explain that, sir, though again there is no way to prove what I think. But it might be that these creatures can control only one mind at a time. The alien may not have realized that I had . . . well . . . knocked Miss Trelawney unconscious and that she was unable to obey its orders, until it came to the spot and saw us. My assumption is that it wasn't till that moment that it switched its mental attack to me."
* * *
The stout man—his name was Laillard White, and he was one of Research's ace trouble-shooters in areas more or less loosely related to psychology—appeared morosely reflective as he and Camhorn left Solar Police Authority Headquarters, and turned toward the adjoining Overgovernment Bureau.
"I gather from your expression," Camhorn remarked, "that our lieutenant was telling the truth."
White grunted. "Of course, he was—as he saw it."
"And he's sane?"
"Quite sane," White agreed absently.
Camhorn grinned. "Then what's the matter, Lolly? Don't you like the idea of time-travel?"
"Naturally not. It's an absurdity."
"You're blunt, Lolly. And rash. A number of great minds differ with you about that."
Laillard White said something rude about great minds in general. He went on, "Was the machine these Trelawneys built found intact?"
Camhorn nodded. "In perfect condition. I found an opportunity to look it over when it and the others the Freeholders had concealed on Terra were brought in."
"And these machines are designed to make it possible to move through time?"
"No question about that. They function in Riemann space, and are very soundly constructed. A most creditable piece of work, in fact. It's only regrettable that the Trelawney brothers were wasted on it. We might have put their talents to better use. Though as it turned out . . ." He shrugged.
White glanced over at him. "What are you talking about?" he asked suspiciously.
"They didn't accomplish time-travel," Camhorn said, "though in theory they should have. I know it because we have several machines based on the same principles. The earliest was built almost eighty years ago. Two are now designed to utilize the YM thrust. The Trelawney machine is considerably more advanced in a number of details than its Overgovernment counterparts, but it still doesn't make it possible to move in time."
"Why not?"
"I'd like to know," Camhorn said. "The appearance of it is that the reality we live in takes the same dim view of time-travel that you do. Time-travel remains a theoretical possibility. But in practice—when, for example, the YM thrust is applied for that purpose—the thrust is diverted."
White looked bewildered. "But if Paul Trelawney didn't move through time, what did he do?"
"What's left?" Camhorn asked. "He moved through space, of course."
"Where?"
Camhorn shrugged. "They penetrated Riemann space," he said, "after harnessing their machine to roughly nineteen thousand times the power that was available to us before the Ymir series of elements dropped into our hands. In theory, Lolly, they might have gone anywhere in the universe. If we'd had the unreasonable nerve to play around with multi-kilograms of YM—knowing what happened when fractional quantities of a gram were employed—we might have had a very similar experience."
"I'm still just a little in the dark, you know," Laillard White observed drily, "as to what the experience consisted of."
"Oh, Lieutenant Dowland's theory wasn't at all far off in that respect. It's an ironic fact that we have much to thank the Trelawneys for. There's almost no question at all now that the race of beings they encountered were responsible for the troubles that have plagued us in the use of YM. They're not the best of neighbors—neighbors in Riemann space terms, that is. If they'd known where to look for us, things might have become rather hot. They had a chance to win the first round when the Trelawneys lit that sixty-eight kilogram beacon for them. But they made a few mistakes, and lost us again. It's a draw so far. Except that we now know about as much about them as they've ever learned about us. I expect we'll take the second round handily a few years from now."
White still looked doubtful. "Was it one of their planets the Trelawneys contacted?"
"Oh, no. At least, it would have been an extremely improbable coincidence. No, the machine was searching for Terra as Terra is known to have been in the latter part of the Pleistocene period. The Trelawneys had provided something like a thousand very specific factors to direct and confine that search. Time is impenetrable, so the machine had to find that particular pattern of factors in space, and did. The aliens—again as Lieutenant Dowland theorized—then moved through Riemann space to the planet where the YM thrust was manifesting itself so violently. But once there, they still had no way of determining where in the universe the thrust had originated—even though they were, in one sense, within shouting distance of Terra, and two of them were actually on its surface for a time. It must have been an extremely frustrating experience all around for our friends."
Laillard White said, "Hm-m," and frowned.
Camhorn laughed. "Let it go, Lolly," he said. "That isn't your field, after all. Let's turn to what is. What do you make of the fact that Dowland appears to have been temporarily immune to the mental commands these creatures can put out?"
"Eh?" White said. His expression turned to one of surprise. "But that's obvious!"
"Glad to hear it," Camhorn said drily.
"Well, it is. Dowland's attitude showed clearly that he suspected the truth himself on that point. Naturally, he was somewhat reluctant to put it into words."
"Naturally. So what did he suspect?"
White shook his head. "It's so simple. The first specimen of humanity the aliens encountered alive was Paul Trelawney. High genius level, man! It would take that level to nullify our I.Q. tests in the manner he and his half-brother did. When those creatures were prowling around on the mesa, they were looking for that kind of mentality. Dowland's above average, far from stupid. As you say, you like his theories. But he's no Trelawney. Unquestionably, the aliens in each case regarded him as some kind of clever domestic animal. The only reason he's alive is that they weren't taking him seriously."
That," Camhorn said thoughtfully, "may have changed a number of things."
"It may, indeed."
"Do we have anything on hand that would block their specific psi abilities?' "
"Oh, surely. If an AR field can stop them, there's nothing to worry about in that respect. Our human telepaths wouldn't be seriously hampered by that degree of interference."
"Very good," Camhorn said. "Do you have any theory about the partial sensory interpretation of the two areas which both Dowland and Miss Trelawney reported? The matter of being able to hear the river on the other planet from time to time."
White nodded. "There are several possible explanations for that. For one thing . . ."
"Better save it for lunch, Lolly," Camhorn interrupted, glancing at his watch. "I see I have two minutes left to make the meeting. Anything else you feel should be brought up at the moment?"
"Just one thing," White said. "If the Trelawneys' machine is capable of locating a Terra-type planet anywhere in the universe . . ."
Camhorn nodded. "It is."
"Then," White said, "we've solved our exploding population problem, haven't we?"
"For the time being, we have," Camhorn agreed. "As a matter of fact, Lolly, that's precisely what the meeting I'm headed for is about."
"Then the Terran Freeholders can stop worrying about the political pressures that have threatened to turn Terra into another hygienically over
crowded slum-world."
"True enough," Camhorn said. "In another few years, if things go right, every man, woman and child can become a Freeholder—somewhere."
"So the Trelawneys got what they wanted, after all. . . ."
"They did, in a way. If the brothers knew the whole score, I think they'd be satisfied. The situation has been explained to their niece. She is."
The End of the Line
The spaceship dropped near evening towards the edge of a curving beach. A half-mile strip of grassy growth stood tall and still behind the beach; beyond the jungle smoothly marbled prows of pink and gray cliffs swept steeply upwards for nearly two thousand feet to the northernmost shelf of a wide, flat continent. The green-black waters of the planet's largest ocean stretched away in a glassy curve ahead, broken by two narrow chains of islands some thirty miles out.
The sleek machine from beyond the stars settled down slowly, a wind thundering out below it and wrinkling the shallows near the beach into sudden zigzag patterns. It fell through explosive sprays of dry sand, sank its base twenty feet deep into the rock below, and stopped. A sharp click announced the opening of a lock a third of the way up its rounded flank; and seven of the nine members of Central Government's Exploration Group 1176 came riding out of the lock a moment later, bunched forty feet above the beach on the tip of their ship's extension ramp.
Six of them dropped free of the ramp at various points of its swooping descent. They hit the hard sand in a succession of soft, bounceless thumps like so many cats and went loping off towards the water. Grevan alone, with the restraint to be looked for in a Group Commander, rode the ramp all the way down to the ground.
He stepped off it unhurriedly there: a very big man, heavy of bone and muscle, though lean where weight wasn't useful, and easy-moving as the professional gladiators and beast-fighters whose training quarters he'd shared in his time. A brooding, implacable expression went so naturally with the rest of it that ordinary human beings were likely to give him one look and step out of his way, even when they weren't aware of his technical rank of Central Government Official.
It was a pity in a way that the members of his Exploration Group weren't so easily impressed.
Grevan scowled reflectively, watching five of the six who had come out of the ship with him begin shucking off weapon belts, suits, and other items of equipment with scarcely a break in their run as they approached the water's edge. Cusat, Eliol, Freckles, Lancey, Vernet—he checked them off mentally as they vanished a few seconds later, with almost simultaneous splashes, from the planet's surface. They were of his own experimental breed or something very near it, born in one of Central Government's germination laboratories and physically, though not quite adults yet, very nearly as capable as Grevan was himself. However, nobody could tell from here what sort of alien, carnivorous life might be floating around beyond this ocean's shallows. . . .
They had too good an opinion of themselves!
Weyer, at any rate, seemed to have decided to stay on shore with his clothes on and his armament handy, in case of trouble. Somewhat reassured, Grevan turned his attention next to a metallic bumping and scraping at the ship's open lock overhead. Klim and Muscles, K.P.'s for the day, were trying to move a bulky cooking unit out of the ship so the Group could dine outdoors.
"Boss?" Klim's clear soprano floated down.
"Right here," Grevan called back. "Having trouble?"
"Looks like we're stuck," Klim announced from within the lock. "Would you come up and . . . no, wait a minute! Muscles is getting it cleared now, I think . . . Wait till I've degraved it again, you big ape! Now, push!"
The cooker popped into sight with a grinding noise, ejected with considerable violence from the ship's interior. For a moment, it hung spinning quietly in the air above the ramp, with Klim perched on top. Then Muscles came out through the lock and attached himself to the gadget's side. They floated down lopsidedly together, accompanied by tinkling sounds from the cooker's interior.
"What's it going to be tonight?" Grevan asked, reaching up to guide them in to an even landing.
"Albert II in mushroom sauce," said Klim. She was a tall, slender blonde with huge blue eyes and a deceptively wistful expression. As he grounded the cooker, she put a hand on his shoulder and stepped down. "Not a very original menu, I'll admit! But there's a nice dessert anyway. How about sampling some local vegetables to go with Albert?"
"Maybe," said Grevan cautiously. "Whose turn is it to sample?" Too often, preoccupied with other matters, he'd discovered suddenly that he'd been roped in again for that chore when the items to be sampled were suspected of being of a particularly uncooperative nature. And then the Group would drop whatever it was doing to gather around and sympathize while he adapted.
"Vernet's turn, isn't it?" said Muscles.
"Vernet's the victim," Klim nodded. "You're safe this time."
"In that case," Grevan said, relieved, "you'll find Vernet out there full fathom five somewhere. Bring her in if you can and we'll go browse in the shrubbery a bit."
"This," Klim remarked, gazing out over the shoreline towards which Muscles was heading in search of Vernet, "is still the best spot of an all-right little world! Know what the cubs were calling it when we first set down here three weeks ago?" She was Grevan's junior by a good ten years but a year or so older than the Group's other members and inclined to regard them all with motherly tolerance. "Our point of no return."
Grevan grimaced uneasily, because that phrase did describe the Group's position here, in one way or another. Never once, in the eight years since Central Government had put him in charge of what had been a flock of rebellious, suspicious, and thoroughly unhappy youngsters, who weren't even sure whether they were actually human beings or some sort of biological robots, had the question of escaping from CG controls been openly discussed among them. You never knew who might be listening, somewhere. The amazing thing to Grevan even now was that—eight weeks travel on the full fury of their great ship's drives beyond the borders of Central Government's sprawling interstellar domain—they did seem to have escaped. But that was a theory that still remained to be proved.
"Are you going to accept contact with CG tomorrow?" Klim inquired.
Grevan shrugged. "I don't know." Their only remaining connection with CG, so far as they could tell, were the vocal messages which flashed subspatially on prearranged occasions between two paired contact sets, one of which was installed on their ship. They had no way of guessing where the other one might be, but it was activated periodically by one of the CG officials who directed the Group's affairs.
"I was going to put it to a vote tonight," Grevan hedged. "They can't possibly trace us through the sets, and I'd like to hear what they have to say when they find out we've resigned."
"It might be a good idea. But you won't get a vote on it."
He looked down at her, while she stooped to haul a small portable cooker out of the big one's interior and slung it over her shoulder.
"Why not?"
"The cubs seem to think there's no way of guessing whether accepting contact at this stage is more likely to help us or hurt us. They'll leave it up to you to decide."
"Aren't you worried about it at all?" he inquired, somewhat startled. However well he felt he knew the cubs, they still managed to amaze him on occasion.
Klim shrugged. "Not too much." She clamped a chemical testing set to the portable cooker. "After all, we're not going back, whatever happens. If CG's still got some fancy way of reaching out and stopping us, wherever we are, I'd much rather be stopped out here than get another going-over in one of their psych laboratories—and come out a mindless-controlled this time. . . ."
She paused. Faint, protesting outcries were arising from a point a few hundred yards out in the water. "Sounds like Muscles caught up with Vernet. Let's get down to the beach."
* * *
Vernet raked wet brown hair out of her eyes and indignantly denied that it was her turn to sample. But the Group con
tradicted her seven to one, with Lancey withholding his vote on a plea of bad memory. She dried and dressed resignedly and came along.
The first three likely-looking growths the foraging party tested and offered her were neither here nor there. They put up no worthwhile argument against assimilation and probably would turn out to be nourishing enough. But raw or variously treated and flavored in Klim's portable cooker, they remained, Vernet reported, as flatly uninspiring as any potential mouthful could hope to be.
The fourth item to pass the chemical tests was a plump little cabbage-arrangement, sky-blue with scarlet leaf-fringes. She sniffed around it forebodingly.
"They don't advertise identity like that for nothing!" she pointed out. "Loaded for bear, I bet!" She scowled at Klim. "You picked it on purpose!"
"Ho-hum," Klim murmured languidly. "Remember who had me sampling that large fried spider-type on wherever-it-was?"
"That was different," said Vernet. "I had a hunch the thing would turn out to be perfectly delicious!"
Klim smiled at her. "I'm K.P. today. I'm having the hunches. How would you like it?"
"Quick-baked," snarled Vernet. "And my blood be on your head!"
Half a minute later, she nibbled tentatively at a crisped leaf of the cabbage, announced with surprise that it was indeed delicious and helped herself to more. On the third leaf, she uttered a wild whoop, doubled up, and began to adapt at speed. That took about twelve seconds, but they allowed a full ten minutes then to let the reaction flush her blood stream. Then Vernet was sampled in turn and staggered back to the beach with a martyred expression, while Klim and Muscles started cabbage-hunting.
Grevan retired to the ship's laboratory, where he poured the half cupful of blood he had extracted from the martyr's veins carefully into a small retort. Ontogenetic adaptation, with reaction-times that crowded zero, to anything new in the way of infections or absorbed venoms was one of the more useful talents of their specialized strain. Considerable unauthorized research and experimentation finally had revealed to them just how they did it. The invading substance was met by an instantaneous regrouping of complex enzyme chains in every body cell affected by it, which matched and nullified its specific harmful properties and left the Group member involved permanently immune to them.
