He had altogether too many unknowns and not enough knowns.
The first specific problem was that of getting into the pirate base. Since the searchers of the Patrol had not found it, that base must be very well hidden indeed. And hiding anything as large as a base on Aldebaran I, as he remembered it, would be quite a feat in itself. He had been in that system only once, but…
Alone in his ship, and in deep space although he was, he blushed painfully as he remembered what had happened to him during that visit. He had chased a couple of dope runners to Aldebaran II, and there he had encountered the most vividly, the most flawlessly, the most remarkably and intriguingly beautiful girl. he had ever seen. He had seen beautiful women, of course, before and in plenty. He had seen beauties amateur and professional, social butterflies, dancers, actresses, models, and posturers, both in the flesh and in Telenewscasts, but he bad never supposed that such an utterly ravishing creature as she was could exist outside of a thionite dream. As a timidly innocent damsel in distress she had been perfect, and if she had held that pose a little longer Kinnison shuddered to think of what might have happened.
But, having known too many dope–runners and too few Patrolmen, she misjudged entirely, not only the cadet's sentiments, but also his reactions. For, even as she came amorously into his arms, he had known that there was something screwy. Women like that did not play that kind of game for nothing. She must be mixed up with the two he had been chasing. He got away from her, with only a couple of scratches, just in time to capture her confederates as they were making their escape—and he had been afraid of beautiful women ever since. He'd like to see that Aldebaranian hell–cat again—just once. He'd been just a kid then, but now…
But that line of thought was getting him nowhere, fast. It was Aldebaran I that he had better be thinking of. Barren, lifeless, desolate, airless, waterless. Bare as his hand, covered with extinct volcanoes, cratered, jagged, and torn. To hide a base on that planet would take plenty of doing, and, conversely, it would be correspondingly difficult to approach. If on the surface at all, which he doubted very strongly, it would be covered. In any event, all its approaches would be thoroughly screened and equipped with lookouts on the ultra–violet and on the infra–red, as well as on the visible. His detector nullifier wouldn't help him much there. Those screens and lookouts were badvery, very bad. Question—could anything get into that base without setting off an alarm?
His speedster could not even get close, that was certain. Could he, alone? He would have to wear armor, of course, to hold his air, and it would radiate. Not necessarily—he could land out of range and walk, without power, but there were still the screens and the lookouts. If the pirates were on their toes it simply wasn't in the cards, and he had to assume that they would be alert.
What, then, could pass those barriers? Prolonged consideration of every fact of the situation gave definite answer and marked out clearly the course he must take. Something admitted by the. pirates themselves was the only thing that could get in. The vessel ahead of his was going in. Therefore he must and would enter that base within the pirate vessel itself. With that point derided there remained only the working out of a method, which proved to be almost ridiculously simple.
Once inside the base, what should he—or rather, what could he—do? For days he made and discarded plans, but finally he tossed them all out of his mind. So much depended upon the location of the base, its personnel, its arrangement, and its routine, that he could develop not even the rough draft of a working plan. He knew what he wanted to do, but he had not even the remotest idea as to how he could go about doing it. Of the openings that appeared, he would have to choose the most feasible and fit his actions to whatever situation then and there obtained.
So deciding, he shot his spy–ray toward the planet and studied it with care. It was indeed as he had remembered it, or worse. Bleakly, hotly arid, it had no soil whatever, its entire surface being composed of igneous rock, lava, and pumice. Stupendous ranges of mountains cries–crossed and intersected each other at random, each range a succession of dead volcanic peaks and blown–off craters. Mountainside and rocky plain, crater–wall and valley floor, alike and innumerably were pockmarked with sub–craters and with immensely yawning shell– holes, as though the whole planet had been throughout geologic ages the target of an incessant cosmic bombardment.
Over its surface and through and through its volume he drove his spy–ray, finding nothing. He bored into its substance with his detectors and his tracers, with results completely negative. Of course, closer up, his electromagnetics would report iron—plenty of it—but that information would also be meaningless. Practically all planets had iron cores. As far as his instruments could tell—and he had given Aldebaran I a more thorough going–over by far than any ordinary surveying ship would have given it—there was no base of any kind upon or within the planet. Yet he knew that a base was there. So what?—maybe—Helmuth's base might be inside the galaxy after all, protected from detection in the same way, probably by solid miles of iron or of iron ore. A second line upon that base had now become imperative. But they were approaching the system fast, he had better get ready.
He belted on his personal equipment, including a nullifier, then inspected his armor, checking its supplies and apparatus carefully before he hooked it ready to his hand. Glancing into the plate, he noted with approval that his "chaser" was functioning perfectly. Pursued and pursuer were now both well inside the solar system of Aldebaran, and, as slowed the pirate so slowed the speedster. Finally the leader went inert in preparation for his spiral, but Kinnison was no longer following. Before .he went inert he flashed down to within fifty thousand miles of the planet's forbidding surface. He then cut his Bergenholm, threw the speedster into an almost circular orbit, well away from the landing orbit selected by the pirate, cut off all his power, and drifted. He stayed in the speedster, observing and computing, until he had so exactly defined its path that he could find it unerringly at any future instant. Then he went into the airlock, stepped out into space, and, waiting only to be sure that the portal had snapped shut behind him, set his course toward the pirate's spiral.
Inert now, his progress was so slow as to seem imperceptible, but he had plenty of time. And it was only relatively that his speed was low. He was actually hurtling through space at the rate of well over two thousand miles an hour, and his powerful little driver was increasing that speed constantly by an acceleration of two Earth gravities.
Soon the vessel crept up, beneath him now, and Kinnison increasing his drive to five gravities, shot toward it in a long, slanting dive. This was the most ticklish minute of the trip, but the Lensman had assumed correctly that the ship's officers would be looking ahead of them and down, not backward and up. They were, and he made his approach unseen. The approach itself, the boarding of an inert spaceship at its frightful landing–spiral velocity, was elementary to any competent space–man. There was not even a flare to bother him or to reveal him to sight, as the braking jets were now doing all the work. Matching course and velocity ever more closely, he crept up—flung his magnet— pulled up, hand over hand—opened the emergency inlet lock—and there he was.
