Needle in a Timestack

by Robert Silverberg

  Within the light you would see a needle ten kilometers long.

  That is the ship. One end tapers to a sharp point and the other has the Eye, and it is several days’ journey by foot from end to end through all the compartments that lie between. It is a world self-contained. The needle is a flattened one. You could walk about easily on the outer surface of the ship, the skin of the top deck, what we call Skin Deck. Or just as easily on Belly Deck, the one on the bottom side. We call one the top deck and the other the bottom, but when you are outside the ship these distinctions have no meaning. Between Skin and Belly lie Crew Deck, Passenger Deck, Cargo Deck, Drive Deck. Ordinarily no one goes from one deck to another. We stay where we belong. The engines are in the Eye. So are the captain’s quarters.

  That needle is the ship, but it is not the whole ship. What you will not be able to see are the annexes and extensions and virtualities. These accompany the ship, enfolding it in a webwork of intricate outstructures. But they are of a subordinate level of reality and therefore they defy vision. A ship tunnels into the void, spreading far and wide to find room for all that it must carry. In these outlying zones are kept our supplies and provisions, our stores of fuel, and all cargo traveling at second-class rates. If the ship transports prisoners, they will ride in an annex. If the ship expects to encounter severe probability turbulence during the course of the voyage, it will arm itself with stabilizers, and those will be carried in the virtualities, ready to be brought into being if needed. These are the mysteries of our profession. Take them on faith, or ignore them, as you will: they are not meant for you to know.

  A ship takes forty years to build. There are two hundred seventy-one of them in service now. New ones are constantly under construction. They are the only link binding the Mother Worlds and the eight hundred ninety-eight Colonies and the colonies of the Colonies. Four ships have been lost since the beginning of the Service. No one knows why. The loss of a starship is the worst disaster I can imagine. The last such event occurred sixty virtual years ago.

  A starship never returns to the world from which it was launched. The galaxy is too large for that. It makes its voyage and it continues onward through heaven in an endless open circuit. That is the service of the Service. There would be no point in returning, since thousands of worldward years sweep by behind us as we make our voyages. We live outside of time. We must, for there is no other way. That is our burden and our privilege. That is the service of the Service.

  On the fifth virtual day of the voyage I suddenly felt a tic, a nibble, a subtle indication that something had gone wrong. It was a very trifling thing, barely perceptible, like the scatter of eroded pebbles that tells you that the palaces and towers of a great ruined city lie buried beneath the mound on which you climb. Unless you are looking for such signals you will not see them. But I was primed for discovery that day. I was eager for it. A strange kind of joy came over me when I picked up that fleeting signal of wrongness.

  I keyed the intelligence on duty and said, “What was that tremor on Passenger Deck?”

  The intelligence arrived instantly in my mind, a sharp gray-green presence with a halo of tingling music.

  “I am aware of no tremor, sir.”

  “There was a distinct tremor. There was a data-spurt just now.”

  “Indeed, sir? A data-spurt, sir?” The intelligence sounded aghast, but in a condescending way. It was humoring me. “What action shall I take, sir?”

  I was being invited to retreat.

  The intelligence on duty was a 49 Henry Henry. The Henry series affects a sort of slippery innocence that I find disingenuous. Still, they are very capable intelligences. I wondered if I had misread the signal. Perhaps I was too eager for an event, any event, that would confirm my relationship with the ship.

  There is never a sense of motion or activity aboard a starship: we float in silence on a tide of darkness, cloaked in our own dazzling light. Nothing moves, nothing seems to live in all the universe. Since we had left Kansas Four I had felt that great silence judging me. Was I really captain of this vessel? Good: then let me feel the weight of duty upon my shoulders.

  We were past Ultima Thule by this time, and there could be no turning back. Borne on our cloak of light, we would roar through heaven for week after virtual week until we came to worldward at the first of our destinations, which was Cul-de-Sac in the Vainglory Archipelago, out by the Spook Clusters. Here in free space I must begin to master the ship, or it would master me.

  “Sir?” the intelligence said.

  “Run a data uptake,” I ordered. “All Passenger Deck input for the past half hour. There was movement. There was a spurt.”

  I knew I might be wrong. Still, to err on the side of caution may be naive, but it isn’t a sin. And I knew that at this stage in the voyage nothing I could say or do would make me seem other than naive to the crew of the Sword of Orion. What did I have to lose by ordering a recheck, then? I was hungry for surprises. Any irregularity that 49 Henry Henry turned up would be to my advantage; the absence of one would make nothing worse for me.

  “Begging your pardon, sir,” 49 Henry Henry reported after a moment, “but there was no tremor, sir.”

  “Maybe I overstated it, then. Calling it a tremor. Maybe it was just an anomaly. What do you say, 49 Henry Henry?” I wondered if I was humiliating myself, negotiating like this with an intelligence. “There was something. I’m sure of that. An unmistakable irregular burst in the data-flow. An anomaly, yes. What do you say, 49 Henry Henry?”

  “Yes, sir.”

  “Yes what?”

  “The record does show an irregularity, sir. Your observation was quite acute, sir.”

  “Go on.”

  “No cause for alarm, sir. A minor metabolic movement, nothing more. Like turning over in your sleep.” You bastard, what do you know about sleep? “Extremely unusual, sir, that you should be able to observe anything so small. I commend you, sir. The passengers are all well, sir.”

  “Very good,” I said. “Enter this exchange in the log, 49 Henry Henry.”

  “Already entered, sir,” the intelligence said. “Permission to decouple, sir?”

  “Yes, you can decouple,” I told it.

  The shimmer of music that signaled its presence grew tinny and was gone. I could imagine it smirking as it went about its ghostly flitting rounds deep in the neural conduits of the ship. Scornful software, glowing with contempt for its putative master. The poor captain, it was thinking. The poor hopeless silly boy of a captain. A passenger sneezes and he’s ready to seal all bulkheads.

  Well, let it smirk, I thought. I have acted appropriately and the record will show it.

  I knew that all this was part of my testing.

  You may think that to be captain of such a ship as the Sword of Orion in your first voyage to heaven is an awesome responsibility and an inconceivable burden. So it is, but not for the reason you think.

  In truth the captain’s duties are the least significant of anyone’s aboard the ship. The others have well-defined tasks that are essential to the smooth running of the voyage, although the ship could, if the need arose, generate virtual replacements for any and every crew member and function adequately on its own. The captain’s task, though, is fundamentally abstract. His role is to witness the voyage, to embody it in his own consciousness, to give it coherence, continuity, by reducing it to a pattern of decisions and responses. In that sense the captain is simply so much software: he is the coding through which the voyage is expressed as a series of linear functions. If he fails to perform that duty adequately, others will quietly see to it that the voyage proceeds as it should. What is destroyed, in the course of a voyage that is inadequately captained, is the captain himself, not the voyage. My pre-flight training made that absolutely clear. The voyage can survive the most feeble of captains. As I have said, four starships have been lost since the Service
began, and no one knows why. But there is no reason to think that any of those catastrophes were caused by failings of the captain. How could they have been? The captain is only the vehicle through which others act. It is not the captain who makes the voyage, but the voyage which makes the captain.

  5.

  Restless, troubled, I wandered the eye of the ship. Despite 49 Henry Henry’s suave mockery I was still convinced there was trouble on board, or about to be.

  Just as I reached Outerscreen Level I felt something strange touch me a second time. It was different this time, and deeply disturbing.

  The Eye, as it makes the complete descent from Skin Deck to Belly Deck, is lined with screens that provide displays, actual or virtual, of all aspects of the ship both internal and external. I came up to the great black bevel-edged screen that provided our simulated view of the external realspace environment and was staring at the dwindling wheel of the Ultima Thule relay point when the new anomaly occurred. The other had been the merest of subliminal signals, a nip, a tickle. This was more like an attempted intrusion. Invisible fingers seemed to brush lightly over my brain, probing, seeking entrance. The fingers withdrew; a moment later there was a sudden stabbing pain in my left temple.

  I stiffened. “Who’s there?”

  “Help me,” a silent voice said.

  I had heard wild tales of passenger matrixes breaking free of their storage circuits and drifting through the ship like ghosts, looking for an unguarded body that they might infiltrate. The sources were unreliable, old scoundrels like Roacher or Bulgar. I dismissed such stories as fables, the way I dismissed what I had heard of the vast tentacular krakens that were said to swim the seas of space, or the beckoning mermaids with shining breasts who danced along the force-lines at spinaround points. But I had felt this. The probing fingers, the sudden sharp pain. And the sense of someone frightened, frightened but strong, stronger than I, hovering close at hand.

  “Where are you?”

  There was no reply. Whatever it was, if it had been anything at all, had slipped back into hiding after that one furtive thrust.

  But was it really gone?

  “You’re still here somewhere,” I said. “I know that you are.”

  Silence. Stillness.

  “You asked for help. Why did you disappear so fast?”

  No response. I felt anger rising.

  “Whoever you are. Whatever. Speak up.”

  Nothing. Silence. Had I imagined it? The probing, the voiceless voice?

  No. No. I was certain that there was something invisible and unreal hovering about me. And I found it infuriating, not to be able to regain contact with it. To be toyed with this way, to be mocked like this.

  This is my ship, I thought. I want no ghosts aboard my ship.

  “You can be detected,” I said. “You can be contained. You can be eradicated.”

  As I stood there blustering in my frustration, it seemed to me that I felt that touch against my mind again, a lighter one this time, wistful, regretful. Perhaps I invented it. Perhaps I have supplied it retroactively.

  But it lasted only a part of an instant, if it happened at all, and then I was unquestionably alone again. The solitude was real and total and unmistakable. I stood gripping the rail of the screen, leaning forward into the brilliant blackness and swaying dizzily as if I were being pulled forward through the wall of the ship into space.

  “Captain?”

  The voice of 49 Henry Henry, tumbling out of the air behind me.

  “Did you feel something that time?” I asked.

  The intelligence ignored my question. “Captain, there’s trouble on Passenger Deck. Hands-on alarm: will you come?”

  “Set up a transit track for me,” I said. “I’m on my way.”

  Lights began to glow in mid-air, yellow, blue, green. The interior of the ship is a vast opaque maze and moving about within it is difficult without an intelligence to guide you. 49 Henry Henry constructed an efficient route for me down the curve of the Eye and into the main body of the ship, and thence around the rim of the leeward wall to the elevator down to Passenger Deck. I rode an air-cushion tracker keyed to the lights. The journey took no more than fifteen minutes. Unaided I might have needed a week.

  Passenger Deck is an echoing nest of coffins, hundreds of them, sometimes even thousands, arranged in rows three abreast. Here our live cargo sleeps until we arrive and decant the stored sleepers into wakefulness. Machinery sighs and murmurs all around them, coddling them in their suspension. Beyond, far off in the dim distance, is the place for passengers of a different sort—a spiderwebbing of sensory cables that holds our thousands of disembodied matrixes. Those are the colonists who have left their bodies behind when going into space. It is a dark and forbidding place, dimly lit by swirling velvet comets that circle overhead emitting sparks of red and green.

  The trouble was in the suspension area. Five crewmen were there already, the oldest hands on board: Katkat, Dismas, Rio de Rio, Gavotte, Roacher. Seeing them all together, I knew this must be some major event. We move on distant orbits within the immensity of the ship: to see as many as three members of the crew in the same virtual month is extraordinary. Now here were five. I felt an oppressive sense of community among them. Each of these five had sailed the seas of heaven more years than I had been alive. For at least a dozen voyages now they had been together as a team. I was the stranger in their midst, unknown, untried, lightly regarded, insignificant. Already Roacher had indicted me for my sweetness, by which he meant, I knew, a basic incapacity to act decisively. I thought he was wrong. But perhaps he knew me better than I knew myself.

  They stepped back, opening a path between them. Gavotte, a great hulking thick-shouldered man with a surprisingly delicate and precise way of conducting himself, gestured with open hands: Here, Captain, see? See?

  What I saw were coils of greenish smoke coming up from a passenger housing, and the glass door of the housing half open, cracked from top to bottom, frosted by temperature differentials. I could hear a sullen dripping sound. Blue fluid fell in thick steady gouts from a shattered support line. Within the housing itself was the pale naked figure of a man, eyes wide open, mouth agape as if in a silent scream. His left arm was raised, his fist was clenched. He looked like an anguished statue.

  They had body-salvage equipment standing by. The hapless passenger would be disassembled and all usable parts stored as soon as I gave the word.

  “Is he irretrievable?” I asked.

  “Take a look,” Katkat said, pointing to the housing readout. All the curves pointed down. “We have nineteen percent degradation already, and rising. Do we disassemble?”

  “Go ahead,” I said. “Approved.”

  The lasers glinted and flailed. Body parts came into view, shining, moist. The coiling metallic arms of the body-salvage equipment rose and fell, lifting organs that were not yet beyond repair and putting them into storage. As the machine labored the men worked around it, shutting down the broken housing, tying off the disrupted feeders and refrigerator cables.

  I asked Dismas what had happened. He was the mind-wiper for this sector, responsible for maintenance on the suspended passengers. His face was open and easy, but the deceptive cheeriness about his mouth and cheeks was mysteriously negated by his bleak, shadowy eyes. He told me that he had been working much farther down the deck, performing routine service on the Strappado-bound people, when he felt a sudden small disturbance, a quick tickle of wrongness.

  “So did I,” I said. “How long ago was that?”

  “Half an hour, maybe. I didn’t make a special note of it. I thought it was something in my gut, Captain. You felt it too, you say?”

  I nodded. “Just a tickle. It’s in the record.” I heard the distant music of 49 Henry Henry. Perhaps the intelligence was trying to apologize for doubting me. “What happened next?” I asked.

  “W
ent back to work. Five, ten minutes, maybe. Felt another jolt, a stronger one.” He touched his forehead, right at the temple, showing me where. “Detectors went off, broken glass. Came running, found this Cul-de-Sac passenger here undergoing convulsions. Rising from his bindings, thrashing around. Pulled himself loose from everything, went smack against the housing window. Broke it. It’s a very fast death.”

  “Matrix intrusion,” Roacher said.

  The skin of my scalp tightened. I turned to him.

  “Tell me about that.”

  He shrugged. “Once in a long while someone in the storage circuits gets to feeling footloose, and finds a way out and goes roaming the ship. Looking for a body to jack into, that’s what they’re doing. Jack into me, jack into Katkat, even jack into you, Captain. Anybody handy, just so they can feel flesh around them again. Jacked into this one here and something went wrong.”

  The probing fingers, yes. The silent voice. Help me.

  “I never heard of anyone jacking into a passenger in suspension,” Dismas said.

  “No reason why not,” said Roacher.

  “What’s the good? Still stuck in a housing, you are. Frozen down, that’s no better than staying matrix.”

  “Five to two it was matrix intrusion,” Roacher said, glaring.

  “Done,” Dismas said. Gavotte laughed and came in on the bet. So too did sinuous little Katkat, taking the other side. Rio de Rio, who had not spoken a word to anyone in his last six voyages, snorted and gestured obscenely at both factions.

  I felt like an idle spectator. To regain some illusion of command I said, “If there’s a matrix loose, it’ll show up on ship inventory. Dismas, check with the intelligence on duty and report to me. Katkat, Gavotte, finish cleaning up this mess and seal everything off. Then I want your reports in the log and a copy to me. I’ll be in my quarters. There’ll be further instructions later. The missing matrix, if that’s what we have on our hands, will be identified, located, and recaptured.”
