Dead Orbit: The Hologram in The Wall

The corridor on Meridian's outer hull smelled of recycled oxygen and rust, the kind of sharp metallic tang that settled into the back of the throat and stayed. Varn moved through it with the particular economy of a man who had spent more years in cramped cargo bays than in anything else, his boots finding each rung of the ladder without looking down. Harlan followed two steps behind, his knees protesting in a way that had nothing to do with age and everything to do with three years of standing in rented rooms, watching numbers on a screen, waiting for an orbit to die.

"You certain this is the right deck?" Varn called back, not stopping. His voice carried the flat neutrality of a man describing weather, dry and unadorned.

"Deck seven, port section, sensor bay C." Harlan's reply was measured, each word placed with the care of a man setting out instruments on a tray. "Tanaka's personnel file lists her as the last active analyst on this array. If she went anywhere to isolate a signal, this is where she would have gone. The far-field sensors here pick up carrier waves from a distance of roughly four months. No one in her division would want to sit closer to the hull than that."

Varn said nothing. The silence he carried with him was not empty. It was the silence of a man who had stopped expecting the world to fill gaps on its own. He reached the end of the corridor where the ladder gave way to a flat-grating catwalk, and he paused, pressing his palm flat against the nearest bulkhead. The metal was cold. Colder than the other sections. He knocked twice, a sharp tap-tap, and listened.

The second knock produced a different resonance. Dull. Dead. The sound of a hollow cavity.

Varn crouched and ran his thumb along the seam where the panel met the frame. His fingers found a hairline gap, just wide enough to catch a thumbnail. He worked it with the flat of his boot heel, then with a salvaged tool from his belt, and the panel shifted inward on concealed hinges, revealing the interior of a space no larger than a strongbox. Inside, nestled in a cradle of foam that had yellowed with age, sat a micro-projector no bigger than a cigarette lighter. Its single lens was dark, but a thin filament of indicator light pulsed along its base, steady as a slow heartbeat.

"It's still running," Varn said. Not a question.

Harlan leaned over his shoulder. The old man's face, all angular planes and creasing skin, shifted into something between curiosity and a precise, academic satisfaction. "The power tap must be tied directly into the array's sensor feed. Self-sustaining. Clever." He reached into his coat and produced a small lens device, held it up to the projector's aperture, and tilted it. "There. A secondary emitter in the panel face. She built her own projection rig from the sensor housing. Tanaka would."

Varn did not respond to this. He was already pressing the projector's activation stud. The device shuddered, emitted a thin whine of cooling electronics, and then the bulkhead panel lit from within.

The hologram bloomed into the corridor in a cone of pale blue light, sharp-edged and cold, the kind of illumination that made the rust on the grating beneath their boots look worse than it was. The figure it resolved was small, compact, dressed in the grey work uniform of the Accord's signal division with the rank insignia removed. Tanaka's face appeared in three-quarter view, her eyes slightly out of focus as though she were looking past the viewer, into a distance that had nothing to do with the corridor on Meridian.

The loop was six minutes long. Varn knew this because he had checked the file metadata before coming up the ladder. Six minutes of recorded time, playing endlessly into the cold air of an empty deck.

Tanaka's voice entered the space. Quiet. Precise. Each consonant placed with the careful, slightly clipped accuracy of a woman translating from a language she had internalized but never fully owned.

"Log seven. Recording for personal retention. No uplink. No copy." A pause. Her eyes found the lens, or the point where the lens had been when she set this up. "The encrypted traffic on carrier twelve-seven-nine has shifted its rotation pattern. Fourth cycle. I have been tracking it for nine days. The originating node moves between the Thessaly-9 relay corridor and the Kellor approach lane every forty-one hours. I have isolated three key exchanges."

The hologram tilted slightly, a micro-adjustment in the recording rig. Tanaka's hands appeared at the edges of the frame, holding a stylus against a tablet that was not present in this projection. She made notes on it. The sound of the stylus was captured in the audio, thin and scratchy, like a fingernail on dry bone.

"The content is not what I expected," she continued. "Not a weapons transfer. Not a routine military resupply. The cipher structure is a black transport protocol, which means the vessel in question is unregistered, unlicensed, and not on any Accord manifest. Docking off-station. No transponder signal. No hull identifier. What it is carrying." She stopped. The stylus did not move. When she spoke again, the word came out flat, stripped of inflection, the way a surgeon names a diagnosis. "Antimatter warheads. Four. Destination column: Thessaly-9 civilian colony. Population two hundred and twelve thousand."

The hologram held this silence for three full seconds. Tanaka's jaw worked once, a small, almost invisible tension in the muscle.

"I have flagged this to my division chief. No response in six hours. I am escalating." Her eyes dropped to the tablet. "If this recording is found and I am not in this room, the key rotations for the full intercept are in the lower register. Page one through nine. The ninth page is the one that matters. It is the vessel's approach vector and the window in which it will be unshielded during docking. Four minutes. That is all you have."

The loop ended. The image dissolved into a soft blue smear, then nothing. The projector's filament faded to a thin amber thread, then darkness. The corridor was just a corridor again, the rust and the recycled air and the quiet tick of expanding metal in the cold.

Varn stood very still. His hands were at his sides, open, fingers slightly curled, as though he were holding something that was no longer there. The dog-tag ring at his ankle caught the faint light from the projector's dying filament. Four tags. Four names. They had not made the last tether mission, and they had not made this one, and the ring did not care that the context had changed. It only clinked, softly, against the sole of his boot when he shifted his weight.

"Thessaly-9," Harlan said. The word came out smooth, posh, carefully enunciated, the way he would have read a line of verse in a lecture hall at the Veshar Institute before the years had worn the music out of his voice. "I have the orbital data. The colony sits in the Lagrange window I designed. The approach vector Tanaka describes, the one on that ninth page, it intersects with a gravitational shear zone I mapped in 2041. A vessel of that mass, unshielded for four minutes, in that window. It would not merely be vulnerable. It would be shredded. Unless."

He stopped. Looked at Varn. The look was patient, the particular patience of a man who had spent forty years explaining orbital mechanics to people who did not want to listen.

"Unless the transport is not docking. Unless it is firing into the shear zone from that position. The warheads would not need to reach the colony. The antimatter annihilation would propagate along the gravitational shear. The colony would simply." He let the word go. Did not say it. Did not need to.

Varn exhaled. It was not a sigh. It was the sound of air leaving a lungs that had been holding too much stillness. "The ninth page."

"Where is it?"

"Doesn't matter." His voice was rough, scraped down to its baseline. "She's not in this room. The file says no active analyst. The loop's been running. I checked the metadata from the station terminal. Nineteen days." He looked at Harlan. "Nineteen days of her sitting in this corridor, probably, waiting for someone to find this. Or waiting for the division chief to answer, and he didn't, and she walked away from the recording and walked into something else."

Harlan was already pulling a data cable from his coat, the kind that plugged into a sensor array's local terminal. He set it on the grating beside them, coiled and ready, his movements slow but deliberate, the way a man handles a scalpel when his hands are still steady. "Then we find the ninth page. Or we find her. Those are the two branches, and they will not converge if we do not move."

Varn picked up the cable. Ran it to the projector's data port. The terminal on the bulkhead flickered, a small panel of green characters that bled into the dark corridor like light through water. He typed. Two characters, a command sequence, the kind that would pull the raw intercept data if Tanaka had stored it locally. The screen stuttered, spat an error, then settled into a directory listing.

Nine files. Pages one through eight were short, technical, cipher rotations and carrier wave logs. The ninth file was larger. The metadata tag read: APPROACH VECTOR DOCKING WINDOW PRIORITY BLACK DO NOT UPLINK.

Varn stared at it. The green text pulsed against the dark, steady, indifferent.

"Harlan." Varn's voice was barely above a whisper, and in the quiet of the empty deck it carried further than it should have. "She wrote do not uplink on the one page that could save two hundred and twelve thousand people."

Harlan was quiet for a moment. Then, very smoothly, in a voice that held the faint, almost ghostly trace of the old lecturer who still stood in front of blackboards and said you are not listening, you are not listening, you are not listening. "That is not a warning, Elias. That is a confession. She knew. She knew the content would be suppressed, so she sealed it behind a restriction tag and built a projector that would loop until someone came. She was not hiding it. She was leaving it. For whoever found this corridor and had the patience to stand in the dark for six minutes, nineteen days, until the loop ended and they looked at the panel and thought to knock."

The green light pulsed. The corridor held its silence. Somewhere deep in Meridian's structure, a pipe groaned, a long, low sound like the station settling into a new angle, and the grating under their boots vibrated once, faintly, and then was still.

Varn plugged in the cable. Page nine loaded onto the terminal, the approach vector unfolding in a cascade of coordinates and timing data. He read it once. Twice. The numbers meant nothing to him in the abstract. They meant something to Harlan, who had designed the very gravitational architecture they described.

"The shear zone narrows in six hours," Harlan said, and his voice had changed. The smoothness was still there, the clipped vowels, the Received precision. But beneath it, something had tightened. A wire pulled taut. "If that transport is on this vector, the window closes at 0340 station time. We have less than two hours to verify the intercept and get someone who can act on it to a position where they can see the hull. If it is there."

Varn pulled the cable. Stood. The dog-tags at his ankle caught the green light, four small shapes swinging with his movement, and he did not look at them. He never looked at them. Not anymore. Not unless someone else saw.

"Where's Voss?" he asked.

"Her clinic is on deck three. The lift shaft is two decks down from here." Harlan was already coiling the cable back into his coat, tucking it away with the careful efficiency of a man who did not leave instruments where others could drop them. "You will need a medic who can think in a room that is on fire. You have her."

Varn moved toward the corridor's far end, where the ladder descended into the deeper structure of the station. His boots struck the grating in a steady, flat rhythm, and the sound of them faded into the tick and groan of the hull, the deep mechanical breathing of a station that had been built to outlast the people inside it. The projector sat in its cradle of yellowed foam, its filament dead, the blue light gone. The loop would not start again. Nineteen days of silence in this corridor, and now a single recording, played once, into an audience of two, and the green text of a file that no one else would ever see unless the two of them chose to carry it out of the dark.

Behind him, Harlan stood at the panel, his fingers resting on the screen, not typing, not scrolling. Just resting. His reflection in the glass was old and angular and very still, and the green light painted his face in a cold, surgical blue. He did not move for a long time. The station creaked around them, settling, the slow groan of metal adjusting to a temperature shift no one on the bridge had noticed.

Then Harlan straightened, straightened his coat, and began the walk back toward the ladder. His footsteps were slower than Varn's, measured, each one placed with the same care he would have used to set a figure in a proof. The gap between them grew. The green text on the terminal glowed alone in the dark corridor, page nine, the approach vector, the four-minute window, the do-not-uplink tag still stamped across it in the cold, flat font of a woman who had trusted the dark to keep a secret for nineteen days and then, when the secret was no longer hers alone, had set it on a loop and walked away into whatever had taken her out of this room.

The projector sat in its cradle. The filament was cold. The loop was over.

And on deck three, two decks down and a half-hour walk away, a field suture kit sat in a drawer in a medic's desk, four years unopened, the thread inside still sharp, the needles still bright, waiting for hands that had not needed them since a boy in a field hospital in Ashward had stopped breathing and a woman had sewn the silence shut with his own kit because no one else's would do and she would not let anyone else's do.

The comms array hummed at a frequency just below hearing, a subsonic thrum Varn felt in his molars rather than his ears. He stood at the main console on deck two, fingers hovering over the trace command, the cursor blinking at him like a slow, patient eye. The intercept had looped eleven times in the dark. He had watched it all. Now he needed to follow the thread back to whatever hand had cast it.

He pressed the sequence. The console flickered. Three receiver ports, the ones pointed toward the outer relay lattice, showed no return signal. Dark. Not sleeping, not cycling. Dead, the way a limb goes dead when you twist the blood flow the wrong way.

"What the..." He muttered it flat, without feeling. His thumb found the override and pushed. The ports stayed black. The diagnostic panel scrolled past: RECEIVER 7, 8, 9, STATUS: OFFLINE, REASON: SCHEDULED MAINTENANCE.

Scheduled maintenance. The words sat in the panel's crisp white font and made no sense to him. Three receivers, out simultaneously, on a station that ran on that relay lattice like a car runs on its engine. You did not pull three. Not on a Tuesday. Not while the whole array was supposed to be tracking.

He called Tanaka.

The connection chirped once, then went to static, then to her voice coming through thin and clean, as if she were speaking from the other side of a window. "I see your trace attempt. I see the three dead ports. Sit down, Varn."

He did not sit down. "You already know about this?"

"I decoded the maintenance flag twenty minutes before you walked onto this deck. I have been watching your approach vector on the corridor cams." A pause, small and deliberate. "The question is not whether I know. The question is whether you want to see the authorization log before I print it for you."

"Print it."

The console purred. A new page slid into the buffer, white text on black, the station's maintenance ledger in its usual drab typeface. Varn read the header, then the body, then the signature block at the bottom.

The signature was clean. Small. The kind of handwriting a man used when he did not want to be remembered for what he had signed.

H. Dray.

Varn set his jaw. The hum of the array dropped into a lower register, or maybe his blood was doing it. The recycled air smelled of ozone and warm polymer, the same smell it had every hour of every shift, and suddenly it tasted like nothing, like the inside of a sealed tube.

"Who authorized the work order?" he asked. Not to Tanaka. To the room. To the station itself, as if the walls might answer.

"My name is on the technical review column," Tanaka said. "Yuki Tanaka, signal-intelligence, black-budget division. Standard cross-signature. I did not authorize it. I verified the technical parameters. The authorization came from orbital operations, and the name at the top of that chain is the one you just read."

Silence. The cursor blinked.

"He knew," Varn said. The words came out low, scraped, the way they do when a man is trying not to let the sound carry. "He knew I was going to trace it. He shut the three receivers that would have given me the origin. Twenty-four hours before the loop even started."

"Yes."

"And the maintenance flag. Scheduled maintenance. That is not a maintenance flag. That is a lock."

"It is a lock dressed in a maintenance flag. I can tell you that with a fair degree of confidence." A small, dry sound from her end. Not quite a laugh. "It is also the kind of thing a man who spent forty years designing relay architectures would know how to do without anyone noticing until they needed the receivers and found them missing."

Varn pulled off his headset and set it on the console, face-down. The metal was warm against his palm, still holding the heat of the last hour.

The third monitor in Voss's workstation blinked amber, then settled back to blue, and in that half-second of color shift a shape registered at the far end of the airlock corridor: shoulders hunched inside a grey maintenance suit, boots striking the grated floor in a rhythm that was two beats too slow for a station engineer. Voss pressed her thumb to the intercom key. The metal bit a cold ridge into her pad, and the smell of the antiseptic wipes she'd been using on the sensor housing drifted up from the tray beside her console, sharp and mint-thick.

"Kellor security, this is medic Voss, station deck three. I have a figure in a maintenance suit at airlock four, moving east toward the sensor array housing. No badge visible on the feed. You are reading?"

Static. A thin, breathy hiss that was not the silence she expected.

She repeated the call. Nothing.

The figure on the feed had not stopped. It moved with a lurch, as though the suit's joints were stiff, and the white of its face was blank, no visor, no expression, just the flat oval of a human behind a darkened filter. Voss leaned forward. Her chair groaned against the deck plating. The antiseptic smell faded, replaced by the warm polymer-and-ozone baseline of the corridor beyond the glass.

"Dray," she said into the dead channel. "You still with me, or did that jammer get your ears too?"

No answer. The light at the far end of the corridor pulsed once, amber, then blue.

The figure raised its right hand and pressed it flat against the floor. The grate beneath it flared orange for a fraction of a second. A sound reached Voss through the glass, muffled but unmistakable: a wet, sizzling crack, like oil meeting a soldering iron. The figure's palm slanted away from the grate, and where it had been, the metal bloomed dark, then blackened into a scorch pattern the size of a coin.

It dropped something.

A small object, no larger than a thumb, tumbled from the figure's left hand and skidded across the grate. It bounced once, twice, and came to rest against the base of the corridor's support strut. A thin wisp of grey smoke rose from it, curling upward in the still air, then dissolving. The figure turned. Its movement was not running. It was a slow, deliberate pivot, and it walked back the way it had come, toward the airlock, toward the dark, its boots striking the grate in that same off-rhythm.

Voss was already on her feet. The chair scraped back across the deck with a shriek that set her teeth on edge. She grabbed the signal-jammer protocol sheet pinned to her workstation's lower panel, folded it into a tight square, and shoved it into the pocket of her coat. The antiseptic wipes clinked in their tray as she turned to run.

She made it three steps before the corridor lights died.

Not a flicker. A clean, total absence, as though the power had been amputated from the junction box. The darkness was so complete that the amber glow of the far monitor was the only point of color, a smudge of rust-colored light in the void. Voss pressed her back against the workstation's metal frame. It was cold where her shoulder blade touched it, the cold of unheated bulkheading, and she could feel the vibration of the figure's retreat through the deck plates below her, a faint, rhythmic thud that faded toward the airlock.

She held still. Counted. The thud stopped.

Then, from the dark ahead of her, a sound: the soft hiss of a service tunnel hatch sliding open. Metal on metal, deliberate, slow, the way you'd open a vault you did not intend to be heard. The figure was gone. Not running. Not falling. Simply no longer in the corridor. The tunnel hatch sealed behind it with a pneumatic sigh, and the lights came back in stages, blue-white, overbearing, and Voss stood in the corridor's full illumination with her hand still pressed flat against the workstation frame, her shoulder sore from the cold of it.

The figure's track ended at the grate. There it was: the scorched palm print, a black rosette of fused polymer and charred metal, still warm enough that a thread of smoke rose from its center. Voss crouched. The smell hit her first, a sharp, acrid bite of burnt insulation that made her eyes water. She reached into her coat pocket, pulled out the folded protocol sheet, and used its edge to scrape the smudge of soot from the grate's surface into a small, neat pile. Beneath the scorch, the grate's alloy was warped, twisted outward in a shallow dome. The heat had been intense and localized. Military-grade.

She straightened and looked at the object at the base of the strut.

The signal jammer. Or what remained of it. A dark disc, no wider than a thumbnail, pitted with half-molten channels where the jammer's discharge had cooked the housing from the inside out. But the face plate was intact. Voss picked it up with two fingers, turning it under the blue light. An insignia was etched into the metal's center, shallow but deliberate: a stylized arch, seven segments, a circle bisected by a horizontal line. Below it, in a font she did not recognize, the words ARCHON CORPS.

"Voss." Varn's voice came from the corridor's far end, low, scraped, the way she had heard it when a man was trying to hold a sound inside his throat. "Voss, where is the jack."

She did not turn. "Airlock four. South corridor. He's gone, Elias. Tunnel access, I think. The hatch is sealed."

Varn appeared in her peripheral vision, his freighter's flight jacket still zippered to the collar, the dog-tag ring at his ankle catching the blue light in a small, rhythmic glint as he walked. He stopped beside the strut. Did not crouch. Simply looked down at the disc in her hand, and his jaw worked once, a tight, lateral pull.

"Archon Corps," he said. Not a question. A flat recitation, the way you'd say a word you were trying to remember the meaning of.

"I don't know it either." Voss set the disc on the grate beside the scorched print. "I checked the Accord's registered military units, the station's local defense roster, the orbital command chain. Nothing. The insignia does not match any division I can account for. It is not in the field-suture kit, for what it is worth." The last part was a joke, or the shape of one. Voss was not in the shape of jokes today.

Varn knelt. His knee struck the grate with a dull thud. He reached for the disc, then stopped, his hand hovering a centimeter above it. "You want to log this? Form seventeen, security incident, unregistered personnel, unregistered equipment."

"I want to log it," Voss said. "I also want to know who authorized a service tunnel access that does not appear on the station's schematic. Because the hatch you heard opening is not in any maintenance plan I have reviewed in two years on this deck."

A silence settled between them, the kind that has weight, the kind that presses against the eardrums. The antiseptic smell had fully faded. In its place, the corridor smelled of char and cold metal and the faint, sweet decay of the burnt polymer under Voss's fingernails.

"Tanaka." Voss said the name into the dead air, a call into a channel that was not dead anymore but still quiet. "Yuki, are you picking up the jammer signature on the array housing?"

The pause was four seconds. Five. Then Tanaka's voice, low, precise, the soft consonants of it rounded at the edges in a way that made the words sound almost like a question even when they were not. "I am. The discharge pattern is consistent with a targeted RF disruption, not a broad-band sweep. Someone dropped a very specific tool on a very specific frequency. The sensor array's calibration is now out of tolerance by eleven percent. I can repair it, but I cannot repair it while the jammer hardware is in the station's dead zone. Which is this corridor. Which is where you are standing."

"Then get your eyes on that disc." Voss held it up. "Archon Corps. Seven-segment arch, bisected circle. Does that ring anything in the black-budget ledger?"

Another pause. Longer. When Tanaka spoke, the clipped rhythm of it had tightened, the careful vowels compressed. "I will check the cipher archive. Give me four minutes."

Voss set the disc on the grate and stepped back. Varn was still kneeling, his hand now flat on the metal, fingertips resting on the edge of the scorched print. The soot was cooling under his touch, and the thread of smoke had thinned to nothing. He was not looking at it. He was looking at the tunnel hatch, at the dark seam where it met the corridor wall, and his jaw had gone still, the tight lateral pull smoothed into a flat, controlled line. The dog tags at his ankle clinked softly as he shifted his weight.

"Harlan." Voss turned. The elderly man stood at the corridor's opposite end, his coat buttoned to the throat, his thin fingers wrapped around the handle of a canvas satchel that had seen better decades. His face was the face of a man who had been listening for a very long time and had only now, at the edge of hearing, caught the last syllable. "The tunnel access," he said. His voice was smooth, the vowels clipped and rounded in that Received cadence, the slow draw of a man who had spent forty years speaking into lecture halls and now spoke into corridors that did not care for precision. "The service tunnel at airlock four was sealed in the original Dray-Kellor architecture. I sealed it. The relay stabilization model requires a clean, uninterrupted service path at that junction. You do not open it unless you are replacing the bulkhead, and I have not replaced that bulkhead in eleven years."

Voss felt the cold of the workstation frame seep back into her shoulder. "Then someone who knows the original schematics opened it. Someone who knows where the junction is, because it is not on the current maintenance maps."

"Correct." Dray said the word with the quiet finality of a man closing a book. He set his satchel on the deck. The canvas was soft against the metal, a small, dry sound. "And the jammer. The discharge pattern Tanaka described. Targeted, narrow-band, eleven percent off-tolerance. That is not a field kit. That is a laboratory instrument, and there are fewer than forty of them in the Accord's registered facilities."

"Fourty," Voss repeated.

"And none of them carry the Archon Corps mark." Dray did not say it as a question. He said it the way you'd set a chess piece on the board: precisely, and with the full knowledge that the player across from you had not yet seen the move.

The corridor lights hummed. The blue-white wash made the scorched print on the grate look obscene, a black smear of something that had once been a hand, a living hand, pressed flat and fused to the metal. Voss looked at it for a long moment. The antiseptic smell was gone. In its place, the faint, sweet decay of burnt polymer, and beneath that, the deeper, more neutral smell of the station itself: recycled air, warm polymer, the mineral tang of the hull.

"Tanaka." Voss keyed the intercom. "You have your four minutes."

"I have my three minutes." A pause. The careful, clipped vowels, the quiet precision of a woman who had learned to translate meaning from static at a very young age. "The cipher archive does not contain the Archon Corps designation. However, the seven-segment arch is a structural echo. It matches the original relay placement diagram from the Veshar Institute, circa the Dray-Kellor stabilization model, revision nine. The bisected circle is not a military symbol. It is an orbital notation. It denotes a station that was designed to be in two orbits simultaneously. A dual-node relay."

The hum of the lights continued. Voss stood very still. The disc sat on the grate, pitted and dark, its etched insignia catching the blue light in small, sharp fragments.

"You are saying," Dray said, and his voice had dropped, the smooth cadence gone quiet, gone slow, the way a man speaks when he is watching a thing he built begin to crack, "that the Archon Corps are not a military unit at all. They are a station."

"A station that was never built. Or one that was built and then erased from the register." Tanaka's voice, still quiet, still careful. "The dual-node relay was a theoretical in revision nine. It was dropped in revision ten. The reason for the drop is not in the public record. It is in the black-budget file, and I do not have clearance to open it."

Varn had stood. The dog tags at his ankle struck the deck once, a small, bright sound in the quiet corridor. He did not look at anyone. He looked at the disc, at the scorch, at the dark seam of the sealed tunnel hatch, and his face did the thing it did when he was deciding whether a silence was a wall or a door.

"Then we open the file," he said. One sentence. Flat. The rough scrape of it, the measured pace, a man who had lost a crew on a tether that was supposed to hold and had not held, who carried four names on a ring of small metal tags and did not take them off even when he slept. "We open the file, and we find out what the Archon Corps are, because whatever walked down that corridor and dropped a jammer on my sensor array is not a maintenance technician, and it is not a ghost, and it is not a mistake."

The disc sat on the grate. The scorch beneath it had cooled to a dull, matte black, the thread of smoke long gone, the sweet polymer smell fading into the station's neutral hum. Above them, the corridor lights held their steady blue, and the dark seam of the tunnel hatch was closed, and the figure was somewhere in the walls, in the sealed and unmarked architecture of a station that had been designed, in a revision that no longer existed, to be two places at once.

Tanaka's voice came again, very quiet, very precise, the careful vowels of a woman who listened for meaning in the spaces between signals. "I can open the file. I will need authorization from orbital operations, and the name at the top of that chain is the one you read an hour ago. I do not have it. But I have the cipher key. I have the key to revision nine."

The blue light hummed. The corridor held its breath. And in the dark seam of the sealed tunnel, far below the grate, in the architecture that had been erased from every map except the one that was a theoretical in a dead institute, something that was not a maintenance technician and was not a ghost pressed a palm flat against the cold wall and waited, patient, for the lights to go out again.
