“Clear.”
“If I am wrong, you may take a lie-detector test and prove it. Then you may punch me in the nose, and I will apologize handsomely.”
I shook my head. He stood up, bowed, and left me sitting there cold sober.
Four films had been taken from the Laskins’ cameras. In the time left to me I ran through them several times without seeing anything out of the way. If the ship had run through a gas cloud, the impact could have killed the Laskins. At perihelion they were moving at better than half the speed of light. But there would have been friction, and I saw no sign of heating in the films. If something alive had attacked them, the beast was invisible to radar and to an enormous range of light frequencies. If the attitude jets had fired accidentally—I was clutching at straws—the light showed on none of the films.
There would be savage magnetic forces near BVS-1, but that couldn’t have done any damage. No such force could penetrate a General Products hull. Neither could heat, except in special bands of radiated light, bands visible to at least one of the puppeteers’ alien customers. I hold adverse opinions on the General Products hull, but they all concern the dull anonymity of the design. Or maybe I resent the fact that General Products holds a near monopoly on spacecraft hulls and isn’t owned by human beings. But if I’d had to trust my life to, say, the Sinclair yacht I’d seen in the drugstore, I’d have chosen jail.
Jail was one of my three choices. But I’d be there for life. Ausfaller would see to that.
Or I could run for it in the Skydiver But no world within reach would have me. If I could find an undiscovered Earthlike world within a week of We Made It…
Fat chance. I preferred BVS-1.
I thought that flashing circle of light was getting bigger, but it flashed so seldom, I couldn’t be sure. BVS-1 wouldn’t show even in my telescope. I gave that up and settled for just waiting.
Waiting, I remembered a long-ago summer spent on Jinx. There were days when, unable to go outside because a dearth of clouds had spread the land with raw blue-white sunlight, we amused ourselves by filling party balloons with tap water and dropping them on the sidewalk from three stories up. They made lovely splash patterns, which dried out too fast. So we put a little ink in each balloon before filling it. Then the patterns stayed.
Sonya Laskin had been in her chair when the chairs had collapsed. Blood samples showed that it was Peter who had struck them from behind, like a water balloon dropped from a great height.
What could get through a General Products hull?
Ten hours to fall.
I unfastened the safety net and went for an inspection tour. The access tunnel was three feet wide, just right to push through in free-fall. Below me was the length of the fusion tube; to the left, the laser cannon; to the right, a set of curved side tubes leading to inspection points for the gyros, the batteries and generator, the air plant, the hyperspace shunt motors. All was in order—except me. I was clumsy. My jumps were always too short or too long. There was no room to turn at the stern end, so I had to back fifty feet to a side tube.
Six hours to go, and still I couldn’t find the neutron star. Probably I would see it only for an instant, passing at better than half the speed of light. Already my speed must enormous.
Were the stars turning blue?
Two hours to go—and I was sure they were turning blue. Was my speed that high? Then the stars behind should be red. Machinery blocked the view behind me, so I used the gyros. The ship turned with peculiar sluggishness. And the stars behind were blue, not red. All around me were blue-white stars.
Imagine light falling into a savagely steep gravitational well. It won’t accelerate. Light can’t move faster than light. But it can gain in energy, in frequency. The light was falling on me harder and harder as I dropped.
I told the dictaphone about it. That dictaphone was probably the best-protected item on the ship. I had already decided to earn my money by using it, just as if I expected to collect. Privately I wondered just how intense the light would get.
Skydiver had drifted back to vertical, with its axis through the neutron star, but now it faced outward. I’d thought I had the ship stopped horizontally. More clumsiness. I used the gyros. Again the ship moved mushily, until it was halfway through the swing. Then it seemed to fall automatically into place. It was as if the Skydiver preferred to have its axis through the neutron star.
I didn’t like that.
I tried the maneuver again, and again the Skydiver fought back. But this time there was something else. Something was pulling at me.
So I unfastened my safety net—and fell headfirst into the nose.
The pull was light, about a tenth of a gee. It felt more like sinking through honey than falling. I climbed back into my chair, tied myself in with the net, now hanging facedown, and turned on the dictaphone. I told my story in such nit-picking detail that my hypothetical listeners could not but doubt my hypothetical sanity. “I think this is what happened to the Laskins,” I finished. “If the pull increases, I’ll call back.”
Think? I never doubted it. This strange, gentle pull was inexplicable. Something inexplicable had killed Peter and Sonya Laskin. QED.
Around the point where the neutron star must be, the stars were like smeared dots of oil paint, smeared radially. They glared with an angry, painful light. I hung facedown in the net and tried to think.
It was an hour before I was sure. The pull was increasing. And I still had an hour to fall.
Something was pulling on me but not on the ship.
No, that was nonsense. What could reach out to me through a General Products hull? It must be the other way around. Something was pushing on the ship, pushing it off course.
If it got worse, I could use the drive to compensate. Meanwhile, the ship was being pushed away from BVS-1, which was fine by me.
But if I was wrong, if the ship was not somehow being pushed away from BVS-1, the rocket motor would send the Skydiver crashing into eleven miles of neutronium.
And why wasn’t the rocket already firing? If the ship was being pushed off course, the autopilot should be fighting back. The accelerometer was in good order. It had looked fine when I had made my inspection tour down the access tube.
Could something be pushing on the ship and on the accelerometer but not on me? It came down to the same impossibility: something that could reach through a General Products hull.
To hell with theory, said I to myself, said I. I’m getting out of here. To the dictaphone I said, “The pull has increased dangerously. I’m going to try to alter my orbit.”
Of course, once I turned the ship outward and used the rocket, I’d be adding my own acceleration to the X-force. It would be a strain, but I could stand it for a while. If I came within a mile of BVS-1, I’d end like Sonya Laskin.
She must have waited facedown in a net like mine, waited without a drive unit, waited while the pressure rose and the net cut into her flesh, waited until the net snapped and dropped her into the nose, to lie crushed and broken until the X-force tore the very chairs loose and dropped them on her.
I hit the gyros.
The gyros weren’t strong enough to turn me. I tried it three times. Each time the ship rotated about fifty degrees and hung there, motionless, while the whine of the gyros went up and up. Released, the ship immediately swung back to position. I was nose down to the neutron star, and I was going to stay that way.
Half an hour to fall, and the X-force was over a gee. My sinuses were in agony. My eyes were ripe and ready to fall out. I don’t know if I could have stood a cigarette, but I didn’t get the chance. My pack of Fortunados had fallen out of my pocket when I had dropped into the nose. There it was, four feet beyond my fingers, proof that the X-force acted on other objects besides me. Fascinating.
I couldn’t take any more. If it dropped me shrieking into the neutron star, I had to use the drive. And I did. I ran the thrust up until I was approximately in free-fall. The blood which had pooled in my extremiti
es went back where it belonged. The gee dial registered one point two gee. I cursed it for a lying robot.
The soft pack was bobbing around in the nose, and it occurred to me that a little extra nudge on the throttle would bring it to me. I tried it. The pack drifted toward me, and I reached, and like a sentient thing it speeded up to avoid my clutching hand. I snatched at it again as it went past my ear, and again it was moving too fast. That pack was going at a hell of a clip, considering that here I was practically in free-fall. It dropped through the door to the relaxation room, still picking up speed, blurred, and vanished as it entered the access tube. Seconds later I heard a solid thump.
But that was crazy. Already the X-force was pulling blood into my face. I pulled my lighter out, held it at arm’s length, and let go. It fell gently into the nose. But the pack of Fortunados had hit like I’d dropped it from a building.
Well.
I nudged the throttle again. The mutter of fusing hydrogen reminded me that if I tried to keep this up all the way, I might well put the General Products hull to its toughest test yet: smashing it into a neutron star at half lightspeed. I could see it now: a transparent hull containing only a few cubic inches of dwarf-star matter wedged into the tip of the nose.
At one point four gee, according to that lying gee dial, the lighter came loose and drifted toward me. I let it go. It was clearly falling when it reached the doorway. I pulled the throttle back. The loss of power jerked me violently forward, but I kept my face turned. The lighter slowed and hesitated at the entrance to the access tube. Decided to go through. I cocked my ears for the sound, then jumped as the whole ship rang like a gong.
And the accelerometer was right at the ship’s center of mass. Otherwise the ship’s mass would have thrown the needle off. The puppeteers were fiends for ten-decimal-point accuracy.
I favored the dictaphone with a few fast comments, then got to work reprogramming the autopilot. Luckily what I wanted was simple. The X-force was but an X-force to me, but now I knew how it behaved. I might actually live through this.
The stars were fiercely blue, warped to streaked lines near that special point. I thought I could see it now, very small and dim and red, but it might have been imagination. In twenty minutes I’d be rounding the neutron star. The drive grumbled behind me. In effective free-fall, I unfastened the safety net and pushed myself out of the chair.
A gentle push aft—and ghostly hands grasped my legs. Ten pounds of weight hung by my fingers from the back of the chair. The pressure should drop fast. I’d programmed the autopilot to reduce the thrust from two gees to zero during the next two minutes. All I had to do was be at the center of mass, in the access tube, when the thrust went to zero.
Something gripped the ship through a General Products hull. A psychokinetic life-form stranded on a sun twelve miles in diameter? But how could anything alive stand such gravity?
Something might be stranded in orbit. There is life in space: outsiders and sailseeds and maybe others we haven’t found yet. For all I knew or cared, BVS-1 itself might be alive. It didn’t matter. I knew what the X-force was trying to do. It was trying to pull the ship apart.
There was no pull on my fingers. I pushed aft and landed on the back wall, on bent legs. I knelt over the door, looking aft/down. When free-fall came, I pulled myself through and was in the relaxation room looking down/forward into the nose.
Gravity was changing faster than I liked. The X-force was growing as zero hour approached, while the compensating rocket thrust dropped. The X-force tended to pull the ship apart; it was two gees forward at the nose, two gees backward at the tail, and diminished to zero at the center of mass. Or so I hoped. The pack and lighter had behaved as if the force pulling them had increased for every inch they had moved sternward.
The back wall was fifteen feet away. I had to jump it with gravity changing in midair. I hit on my hands, bounced away. I’d jumped too late. The region of free-fall was moving through the ship like a wave as the thrust dropped. It had left me behind. Now the back wall was up to me, and so was the access tube.
Under something less than half a gee, I jumped for the access tube. For one long moment I stared into the three-foot tunnel, stopped in midair and already beginning to fall back, as I realized that there was nothing to hang on to. Then I stuck my hands in the tube and spread them against the sides. It was all I needed. I levered myself up and started to crawl.
The dictaphone was fifty feet below, utterly unreachable. If I had anything more to say to General Products, I’d have to say it in person. Maybe I’d get the chance. Because I knew what force was trying to tear the ship apart.
It was the tide.
The motor was off, and I was at the ship’s midpoint. My spread-eagled position was getting uncomfortable. It was four minutes to perihelion.
Something creaked in the cabin below me. I couldn’t see what it was, but I could clearly see a red point glaring among blue radial lines, like a lantern at the bottom of a well. To the sides, between the fusion tube and the tanks and other equipment, the blue stars glared at me with a light that was almost violet. I was afraid to look too long. I actually thought they might blind me.
There must have been hundreds of gravities in the cabin. I could even feel the pressure change. The air was thin at this height, one hundred fifty feet above the control room.
And now, almost suddenly, the red dot was more than a dot. My time was up. A red disk leapt up at me; the ship swung around me; I gasped and shut my eyes tight. Giants’ hands gripped my arms and legs and head, gently but with great firmness, and tried to pull me in two. In that moment it came to me that Peter Laskin had died like this. He’d made the same guesses I had, and he’d tried to hide in the access tube. But he’d slipped…as I was slipping…From the control room came a multiple shriek of tearing metal. I tried to dig my feet into the hard tube walls. Somehow they held.
When I got my eyes open, the red dot was shrinking into nothing.
The puppeteer president insisted that I be put in a hospital for observation. I didn’t fight the idea. My face and hands were flaming red, with blisters rising, and I ached as though I’d been beaten. Rest and tender loving care; that was what I wanted.
I was floating between a pair of sleeping plates, hideously uncomfortable, when the nurse came to announce a visitor. I knew who it was from her peculiar expression.
“What can get through a General Products bull?” I asked it.
“I hoped you would tell me.” The president rested on its single back leg, holding a stick that gave off green incense-smelling smoke.
“And so I will. Gravity.”
“Do not play with me, Beowulf Shaeffer. This matter is vital.”
“I’m not playing. Does your world have a moon?”
“That information is classified.” The puppeteers are cowards. Nobody knows where they come from, and nobody is likely to find out.
“Do you know what happens when a moon gets too close to its primary?”
“It falls apart.”
“Why?”
“I do not know.”
“Tides.”
“What is a tide?”
Oho, said I to myself, said I. “I’m going to try to tell you. The Earth’s moon is almost two thousand miles in diameter and does not rotate with respect to Earth. I want you to pick two rocks on the moon, one at the point nearest the Earth, one at the point farthest away.”
“Very well.”
“Now, isn’t it obvious that if those rocks were left to themselves, they’d fall away from each other? They’re in two different orbits, mind you, concentric orbits, one almost two thousand miles outside the other. Yet those rocks are forced to move at the same orbital speed.”
“The one outside is moving faster.”
“Good point. So there is a force trying to pull the moon apart. Gravity holds it together. Bring the moon close enough to Earth, and those two rocks would simply float away.”
“I see. Then this ‘tide’
tried to pull your ship apart. It was powerful enough in the lifesystem of the Institute ship to pull the acceleration chairs out of their mounts.”
“And to crush a human being. Picture it. The ship’s nose was just seven miles from the center of BVS-1. The tail was three hundred feet farther out. Left to themselves, they’d have gone in completely different orbits. My head and feet tried to do the same thing when I got close enough.”
“I see. Are you molting?”
“What?”
“I notice you are losing your outer integument in spots.”
“Oh, that. I got a bad sunburn from exposure to starlight. It’s not important.”
Two heads stared at each other for an eyeblink. A shrug? The puppeteer said, “We have deposited the residue of your pay with the Bank of We Made It. One Sigmund Ausfaller, human, has frozen the account until your taxes are computed.”
“Figures.”
“If you will talk to reporters now, explaining what happened to the Institute ship, we will pay you ten thousand stars. We will pay cash so that you may use it immediately. It is urgent. There have been rumors.”
“Bring ’em in.” As an afterthought I added, “I can also tell them that your world is moonless. That should be good for a footnote somewhere.”
“I do not understand.” But two long necks had drawn back, and the puppeteer was watching me like a pair of pythons.
“You’d know what a tide was if you had a moon. You couldn’t avoid it.”
“Would you be interested in—”
“A million stars? I’d be fascinated. I’ll even sign a contract if it states what we’re hiding. How do you like being blackmailed for a change?”

GHOST: TWO
I tried to script the story myself, of course. There was a computer program that would do it as an interview. I made lots of notes…too many notes, because any time I tried to write text for myself, I blocked.
