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 mito 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.»
