However, the ship would be a refuge, if it were still there, and Hoerwitz wanted to get there before any possible guard. He therefore set out at the highest speed he could manage, climbing across the asteroid.
It was like chimney work in Earthly rock-climbing, simpler in one way because there was no significant weight. The manager was not really good at it, but presumably he was better than the others.
Earth was overhead and slightly to the west—about as far as it ever got that way, seen from near the airlock. That meant that time was growing short. When the planet started eastward again the asteroid was within a hundred degrees or so of perigee—an arc which it would cover in little over three-quarters of an hour, at this end of its grossly eccentric orbit.
Travel grew more complicated, and rather more dangerous, as the planet sank behind him. Roche’s limit for a body of this density was at around twelve thousand miles from Earth’s center, and the tidal bulge—invisible, imponderable, a mere mathematical quirk of earth’s potential field—was not only swinging around but growing stronger. With Earth, now spanning more than thirty degrees of sky, on the horizon behind him he was safe, but as it sank he knew he was traveling to meet the bulge, and it was coming to meet him. He had to get to the ship before the field had been working on that area too long.
The last thousand feet should have been the hardest, with his weight turning definitely negative; physically, it turned out to be the easiest, though the reason shocked him. He discovered, by the simple expedient of running into it, that the thieves had strung a cable between their ship and the airlock.
With its aid, they would travel much faster than he could. There might be a guard there already. Mac, terrified almost out of his senses, pulled himself along the cable with reckless haste until he reached a point where he could see the base of the ship a few hundred feet away.
No spacesuits were in sight, but the bottom of the globe was in black shadow. There was no way to be sure—except by waiting. That would eventually make one thing certain. The old man almost hurled himself along the cable toward the ship, expecting every second to be his last, but trying to convince himself that no one was there.
He was lucky. No one was.
The ship was already off the “ground” by a foot or so; the tide was rising at this part of the asteroid and weight had turned negative. Hoerwitz crammed himself into the space between the spherical hull and the ground and heaved upward for all he was worth.
At a guess, his thrust amounted to some fifty pounds. This gave him something over a minute before the vessel was too high for further pushing. In this time it had acquired a speed of perhaps two inches a second relative to the asteroid; but this was still increasing, very slowly, under tidal thrust.
The hull was of course covered with handholds. Hoerwitz seized two of these and rode upward with the vessel. It was quite true that a man drifting in space was an almost hopeless proposition as far as search-and-rescue was concerned; but a ship was a very different matter. If he and it got far enough away before any of the others arrived, he was safe.
Altitude increased with agonizing slowness. Earth’s bulk gradually came into view all around the planetoid’s jagged outline. At first, the small body showed almost against the center of the greater one; then, as the ship in its larger, slower orbit began to fall behind, the asteroid appeared to drift toward one side of the blue-and-white streaked disk. Hoerwitz watched with interest and appreciation—it was a beautiful sight—but didn’t neglect the point where the cable came around the rocks.
He was perhaps five hundred feet up when a space-suited figure appeared, pulling itself along with little appearance of haste. It was not yet close enough for the ship’s former site to be above the “horizon.” Mac waited with interest to see what the reaction to the discovery would be.
It was impressive, even under circumstances which prevented good observation. The thief was surprised enough to lose grip on the cable.
He was probably traveling above escape velocity, or what would have been escape velocity, even if the tide had been out. As it was, any speed would have been too great. For a moment, Hoerwitz thought the fellow was doomed.
Maybe it was Robinson, though; at least, he reacted promptly and sensibly. He drew a gun and began firing away from the asteroid. Each shot produced only a tiny velocity change in his drifting body, but those few inches a second were enough. He collided with one of the structures at the base of a radiator, kicked himself off and downward as he hit it, touched the surface, and clutched frantically at some handhold Hoerwitz couldn’t see. Then he began looking around and promptly discovered the ship.
The manager was quite sure the fellow wouldn’t try a jump. He wished, once again, that his radio receiver was working—the man might be saying something interesting, though he must be out of radio reach of the others. It would be nice to know whether the thief could see Hoerwitz’s clinging figure on the ship’s hull. It was possible, since the lower side of the sphere was illuminated by Earthlight, but far from certain, since the man’s line of sight extended quite close to the sun. He wasn’t shooting. But it was more than likely that his gun was empty anyway.
It was disappointing in a way, but Hoerwitz was able to make up for himself a story of what the fellow was thinking, and this was probably more fun than the real facts. Eventually the figure worked its way back to the cable and started along it toward the airlock. The old man watched it out of sight. Then feeling almost secure, he resumed his favorite state of relaxation after fastening himself to a couple of holds with the snap-rings on his suit, and relaxed.
There was nothing more to do. The drifting vessel would be spotted in the next hour or so, if it hadn’t been already, and someone would be along. In a way, it was a disappointing ending.
He spent some of the time wondering what Shakespeare would have done to avoid the anticlimax. He might have learned, if he had stayed awake, but he slept through the interesting part.
Smith, upon hearing that the ship was drifting away, had made the best possible time to the radiator site. Knowing that there was no other hope, he jumped; and not being a lightning calculator able to make all the necessary allowances for the local quirks in the potential field, he naturally went slightly off course.
He used all but one of his bullets in attempted corrections and wound up drifting at a velocity very well matched with that of the ship, but about fifty yards away from it. He could see Hoerwitz plainly.
Up to that time he had had no intention either of harming the old man fatally or blowing up the station; but the realization that the manager had had a part in the loss of his ship changed his attitude drastically. When the police ship arrived, he was still trying to decide whether to fire his last bullet at Hoerwitz, or in the opposite direction. Hoerwitz himself, of course, was asleep.
