Chapter XII

"But listen, Kim!" Clarrissa protested. "What makes you all so sure that it's Overlords? There's nothing on my map there to prove--Why, it might be _anything_!"

"It might not, too," Kinnison stated. "Barring the contingency of the existence of a life form unknown to any one of the four of us and which operates exactly as the Overlords do operate, that hypothesis is the only one both necessary and sufficient to explain all the facts which you have plotted upon your chart. Think a minute--you know how they work. They tune in on some one mind, the stronger and more vital the better. The fact that the Lyranians have such powerful minds is undoubtedly one big reason why the Overlords are here. In that connection, it's a mystery to me how Helen has lived so long--all the persons who disappeared had high-powered minds, didn't they?"

She thought for a space. "Now that you mention it, I believe that they did; as far as I know, anyway."

"Thought so. That clinches it, if it needed any clinching. But to go on, they tune in and blank out the victim's mind completely, filling it with an overwhelming urge to rush directly to the cavern. How else can you explain the number of these disappearances; and above all, the fact that the great majority of those lines of yours point directly to that one spot? For your information, I will add that the ones that do not so point are probably observational errors--the person was seen before she disappeared, instead of afterward."

"But that's so ... so _evident_," she began. "Would they do anything--"

"It wasn't evident to you at first, was it?" he countered. "And, evident or not, they always have worked that way; and, as far as anyone has been able to find out, they never have worked any other way. Quite probably, therefore, they can't. The Eich undoubtedly told them to lay off, just as they did before; but apparently they can't do that, either--permanently. This torturing and life eating of theirs seems to be a racial vice--like a drug habit, only worse. They can quit it for a while, but after about so long they simply have to go on another bender. Convinced?"

"Wel-l-l, I suppose so," she admitted doubtfully, and Kinnison turned to the group at large.

"There is no doubt, I take it, as to what course of action we are to pursue in the matter of this cavern of Overlords?" he asked, superfluously.

There was none. The decision was unanimous and instant that it must be wiped out. The two great ships, the incomparable _Dauntless_ and the camouflaged warship which had served Kinnison-Cartiff so well, lifted themselves into the stratosphere and headed north. The Lensmen did not want to advertise their presence and there was no great hurry, therefore both vessels had their thought-screens out and both rode upon baffled jets.

Practically all of the crewmen of the _Dauntless_ had seen Overlords in the substance; so far as is known they were the only human beings who had ever seen an Overlord and had lived to tell of it. Twenty-two of their former fellows had seen Overlords and had died. Kinnison, Worsel and Van Buskirk had slain Overlords in unscreened hand-to-hand combat in the fantastically incredible environment of a hyperspatial tube--that uncanny medium in which man and monster could and did occupy the same space at the same time without being able to touch each other; in which the air or pseudoair is thick and viscous; in which the only substance common to both sets of dimensions and thus available for combat purposes is a synthetic material so treated and so saturated as to be of enormous mass and inertia.

* * * * *

It is easier to imagine, then, than to describe the emotion which seethed through the crew as the news flew around that the business next in order was the extirpation of a flock of Overlords.

"How about a couple or three nice duodec torpedoes, Kim, steered right down into the middle of that cavern and touched off--_powie!_--slick, don't you think?" Henderson insinuated.

"Aw, let's not, Kim!" protested Van Buskirk, who, as one of the three Overlord slayers, had been called into the control room. "This ain't going to be in a tube, Kim; it's in a cavern on a planet--made to order for ax work. Let me and the boys put on our screens and bash their ugly damn skulls in for 'em. How about it, huh?"

"Not duodec, Hen--not yet, anyway," Kinnison decided. "As for ax work, Bus--maybe, maybe not. Depends. We want to catch some of them alive, so as to get some information--but you and your boys will be good for that, too, so you might as well go and start getting them ready." He turned his thought to his snakish comrade in arms.

"What do you think, Worsel, is this hide-out of theirs heavily fortified, or just hidden?"

"Hidden, I would say from what I know of them--well-hidden," the Velantian replied promptly. "Unless they have changed markedly; and, like you, I do not believe that a race so old can change that much. I could tune them in, as I have done before, but it might very well do more harm than good."

"Certain to, I'm afraid." Kinnison knew as well as did Worsel that a Velantian was the tastiest dish which could be served up to any Overlord. Both knew also, however, the very real mental ability of the foe; knew that the Overlords would be sure to suspect that any Velantian so temptingly present upon Lyrane II must be there specifically for the detriment of the Delgonian race; knew that they would almost certainly refuse the proffered bait. And not only would they refuse to lead Worsel to their cavern, but in all probability they would cancel even their ordinary activities, thus making it impossible to find them at all, until they had learned definitely that the hook-bearing titbit and its accomplices had left the Lyranian solar system entirely. "No, what we need right now is a good, strong-willed Lyranian."

"Shall we go back and grab one? It would take only a few minutes," Henderson suggested, straightening up at his board.

"Uh-uh," Kinnison demurred. "That might smell a bit on the cheesy side, too, don't you think, fellows?" And Worsel and Tregonsee agreed that such a move would be ill-advised.

"Might I offer a barely tenable suggestion?" Nadreck asked diffidently.

"I'll say you can--come in."

"Judging by the rate at which Lyranians have been vanishing of late, it would seem that we would not have to wait too long before another one comes hither under her own power. Since the despised ones will have captured her themselves, and themselves will have forced her to come to them, no suspicion will be or can be aroused."

"That's a thought, Nadreck--that _is_ a thought!" Kinnison applauded. "Shoot us up, will you, Hen? 'Way up, and hover over the center of the spread of intersections of those lines. Put observers on every plate you've got here--you, too, Captain Craig, please, all over the ship. Have half of them search the air all around as far as they can reach for an airplane in flight; have the rest comb the terrain below, both on the surface and underground, with spy-rays, for any sign of a natural or artificial cave."

"What kind of information do you think they may have, Kinnison?" asked Tregonsee the Rigellian.

"I don't know." Kinnison pondered for minutes. "Somebody--around here somewhere--has got some kind of a tie-up with some Boskonian entity or group that is fairly well up the ladder; I'm pretty sure of that. Bleeko sent ships here--one speedster, certainly, and there's no reason to suppose that it was an isolated case--"

"There is nothing to show, either, that it was not an isolated case," Tregonsee commented quietly, "and the speedster landed, not up here near the pole, but in the populated zone. Why? To secure some of the women?" The Rigellian was not arguing against Kinnison; he was, as they all knew, helping to subject every facet of the matter to scrutiny.

"Possibly--but this is a transfer point," Kinnison pointed out. "Illona was to start out from here, remember. And those two ships--coming to meet her, or perhaps each other, or--"

"Or perhaps called there by the speedster's crew, for aid," Tregonsee supplied the complete thought.

"One but quite possibly not both," Nadreck suggested. "We agreed, I think, that the probability of a Boskonian connection is sufficiently large to warrant the taking of these Overlords alive in order to read their minds?"

* * * * *

They were; hence the discussion then turned naturally to the question of how this none-too-easy feat was to be accomplished. The two Patrol ships had climbed and were cruising in great, slow circles; the spy-ray men and the other observers were hard at work. Before they had found anything upon the ground, however:

"Plane, ho!" came the report, and both vessels, with spy-ray blocks out now as well as thought-screens, plunged silently into a flatly slanting dive. Directly over the slow Lyranian craft, high above it, they turned as one to match its course and slowed down to match its pace.

"Come to life, Kim--don't let them have her!" Clarrissa exclaimed. Being _en rapport_ with them all, she knew that both unhuman Worsel and monster Nadreck were perfectly willing to let the helpless Lyranian become a sacrifice; she knew that neither Kinnison nor Tregonsee had as yet given that angle of the affair a single thought. "Surely, Kim, you don't have to let them kill her, do you? Isn't showing you the gate or whatever it is, enough? Can't you rig up something to do something with when she gets almost inside?"

"Why ... uh ... I s'pose so." Kinnison wrenched his attention away from a plate. "Oh, sure, Chris. Hen! Drop us down a bit, and have the boys get ready to spear that crate with a couple of tractors when I give the word."

The plane held its course, directly toward a range of low, barren, precipitous hills. As it approached them it dropped, as though to attempt a landing upon a steep and rocky hillside.

"She can't land there," Kinnison breathed, "and Overlords would want her alive, not dead--suppose I've been wrong all the time? Get ready, fellows!" he snapped. "Take her at the very last possible instant--before--she--crashes--_now!_" As he yelled the command the powerful beams leaped out, seizing the disaster-bound vehicle in a gently unbreakable grip. Had they not done so, however, the Lyranian would not have crashed; for in that last split second a section of the rugged hillside fell inward. In the very mouth of that dread opening the little plane hung for an instant; then:

<hr class="chap">

"Grab the woman, quick!" Kinnison ordered, for the Lyranian was going to jump.

And, such was the awful measure of the Overlords' compulsion, she did jump; without a parachute, without knowing or caring what, if anything, was to break her fall. But before she struck ground a tractor beam had seized her, and passive plane and wildly struggling pilot were both borne rapidly aloft.

"Why, Kim, it's _Helen_!" Clarrissa shrieked in surprise, then voice and manner became transformed. "The poor, poor thing," she crooned. "Bring her in at No. 6 Lock. I'll meet her there--you fellows keep clear. In the state she's in a shock--especially such a shock as seeing such a monstrous lot of males--would knock her off the beam, sure."

* * * * *

Helen of Lyrane ceased struggling in the instant of being drawn through the thought-screen surrounding the _Dauntless_. She had not been unconscious at any time. She had known exactly what she had been doing; she had wanted intensely--such was the insidiously devastating power of the Delgonian mind--to do just that and nothing else. The falseness of values, the indefensibility of motivation, simply could not register in her thoroughly suffused, completely blanketed mind. When the screen cut off the Overlords' control, however, thus restoring her own, the shock of realization of what she had done--what she had been forced to do--struck her like a physical blow. Worse than a physical blow, for ordinary physical violence she could understand.

This mischance, however, she could not even begin to understand. It was utterly incomprehensible. She knew what had happened; she knew that her mind had been taken over by some monstrously alien, incredibly powerful mentality, for some purpose so obscure as to be entirely beyond her ken. To her narrow philosophy of existence, to her one-planet insularity of viewpoint and outlook, the very existence, anywhere, of such a mind with such a purpose was in simple fact impossible. For it actually to exist upon her own planet, Lyrane II, was sheerly, starkly unthinkable.

She did not recognize the _Dauntless_, of course. To her all spaceships were alike. They were all invading warships, full of enemies. All things and all beings originating elsewhere than upon Lyrane II were, perforce, enemies. Those outrageous males, the Tellurian Lensman and his cohorts, had pretended not to be inimical, as had the peculiar, white-swathed Tellurian near-person who had been worming itself into her confidence in order to study the disappearances; but she did not trust even them.

She now knew the manner of, if not the reason for, the vanishment of her fellow Lyranians. The tractors of the spaceship had saved her from whatever fate it was that impended. She did not, however, feel any thrill of gratitude. One enemy or another, what difference did it make? Therefore, as she went through the blocking screen and recovered control of her mind, she set herself to fight; to fight with every iota of her mighty mind and with every fiber of her lithe, hard-schooled, tigress' body. The air-lock doors opened and closed--she faced, not an armed and armored male all set to slay, but the white-clad person whom she already knew better than she ever would know any other non-Lyranian.

"Oh, Helen!" the girl half sobbed, throwing both arms around the still-braced Chief Person. "I'm _so_ glad that we got to you in time! And there will be no more disappearances, dear--the boys will see to that!"

Helen did not know, really, what disinterested friendship meant. Since the nurse had put her into a wide-open two-way, however, she knew beyond all possibility of doubt that these Tellurians wished her and all her kind well, not ill; and the shock of that knowledge, superimposed upon the other shocks which she had so recently undergone, was more than she could bear. For the first and only time in her hard, busy, purposeful life, Helen of Lyrane fainted; fainted dead away in the circle of the Earthgirl's arms.

The nurse knew that this was nothing serious; in fact, she was professionally quite in favor of it. Hence, instead of resuscitating the Lyranian, she swung the pliant body into a carry--as has been previously intimated, Clarrissa MacDougall was no more a weakling physically than she was mentally--and without waiting for orderlies and stretcher she bore it easily away to her own quarters. And there, instead of administering restoratives, she took out her ubiquitous hypodermic and made sure that her patient would rest quietly for many hours to come.
