I was the youngest officer on board, so naturally I was captain.

  They put you in command right at the start, before you’re anyone. That’s the only test that means a damn: they throw you in the sea and if you can swim you don’t drown, and if you can’t you do. The drowned ones go back in the tank and they serve their own useful purposes, as push-cells or downloaders or mind-wipers or Johnny-scrub-and-scour or whatever. The ones that don’t drown go on to other commands. No one is wasted. The Age of Waste has been over a long time.

  On the third virtual day out from Kansas Four, Roacher told me that I was the sweetest captain he had ever served under. And he had served under plenty of them, for Roacher had gone up to heaven at least two hundred years before, maybe more.

  “I can see it in your eyes, the sweetness. I can see it in the angle you hold your head.”

  He didn’t mean it as a compliment.

  “We can put you off ship at Ultima Thule,” Roacher said. “Nobody will hold it against you. We’ll put you in a bottle and send you down, and the Thuleys will catch you and decant you and you’ll be able to find your way back to Kansas Four in twenty or fifty years. It might be the best thing.”

  Roacher is small and parched, with brown skin and eyes that shine with the purple luminescence of space. Some of the worlds he has seen were forgotten a thousand years ago.

  “Go bottle yourself, Roacher,” I told him.

  “Ah, Captain, Captain! Don’t take it the wrong way. Here, Captain, give us a touch of the sweetness.” He reached out a claw, trying to stroke me along the side of my face. “Give us a touch, Captain, give us just a little touch!”

  “I’ll fry your soul and have it for breakfast, Roacher. There’s sweetness for you. Go scuttle off, will you? Go jack yourself to the mast and drink hydrogen, Roacher. Go. Go.”

  “So sweet,” he said. But he went. I had the power to hurt him. He knew I could do it, because I was captain. He also knew I wouldn’t; but there was always the possibility he was wrong. The captain exists in that margin between certainty and possibility. A crewman tests the width of that margin at his own risk. Roacher knew that. He had been a captain once himself, after all.

  There were seventeen of us to heaven that voyage, staffing a ten-kilo Megaspore-class ship with full annexes and extensions and all virtualities. We carried a bulging cargo of the things regarded in those days as vital in the distant colonies: pre-read vapor chips, artificial intelligences, climate nodes, matrix jacks, mediq machines, bone banks, soil converters, transit spheres, communication bubbles, skin-and-organ synthesizers, wildlife domestication plaques, gene replacement kits, a sealed consignment of obliteration sand and other proscribed weapons, and so on. We also had fifty billion dollars in the form of liquid currency pods, central-bank-to-central-bank transmission. In addition there was a passenger load of seven thousand colonists. Eight hundred of these were on the hoof and the others were stored in matrix form for body transplant on the worlds of destination. A standard load, in other words. The crew worked on commission, also as per standard, one percent of bill-of-lading value divided in customary lays. Mine was the fiftieth lay—that is, two percent of the net profits of the voyage—and that included a bonus for serving as captain; otherwise I would have had the hundredth lay or something even longer. Roacher had the tenth lay and his jackmate Bulgar the fourteenth, although they weren’t even officers. Which demonstrates the value of seniority in the Service. But seniority is the same thing as survival, after all, and why should survival not be rewarded? On my most recent voyage I drew the nineteenth lay. I will have better than that on my next.

  3.

  You have never seen a starship. We keep only to heaven; when we are to worldward, shoreships come out to us for the downloading. The closest we ever go to planetskin is a million shiplengths. Any closer and we’d be shaken apart by that terrible strength which emanates from worlds.

  We don’t miss landcrawling, though. It’s a plague to us. If I had to step to shore now, after having spent most of my lifetime in heaven, I would die of the drop-death within an hour. That is a monstrous way to die; but why would I ever go ashore? The likelihood of that still existed for me at the time I first sailed the Sword of Orion, you understand, but I have long since given it up. That is what I mean when I say that you give up your life when you go to heaven. But of course what also goes from you is any feeling that to be ashore has anything to do with being alive. If you could ride a starship, or even see one as we see them, you would understand. I don’t blame you for being what you are.

  Let me show you the Sword of Orion. Though you will never see it as we see it.

  What would you see, if you left the ship as we sometimes do to do the starwalk in the Great Open?

  The first thing you would see was the light of the ship. A starship gives off a tremendous insistent glow of light that splits heaven like the blast of a trumpet. That great light both precedes and follows. Ahead of the ship rides a luminescent cone of brightness bellowing in the void. In its wake the ship leaves a photonic track so intense that it could be gathered up and weighed. It is the stardrive that issues this light: a ship eats space, and light is its offthrow.

  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.

  4.

  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 n
ot 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 naïve, 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 naïve 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 frustrati
on, 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.
