The Vast Meridian: The Signal

The pulse came in at 0347, ship time, while Marshal Rourke was running a coolant diagnostic on the PRAETOR's number two heat exchanger. He knew the precise time because the diagnostic counter in his visor flickered, reset, and began counting again from zero, the rhythm of the pulse beating against the PRAETOR's instruments like a slow heart.

He straightened up from the open maintenance panel, his knees aching from the crouched position. The PRAETOR's sensor bay occupied the forward port of the engineering deck, a cramped alcove of glassine readouts and humming relays wedged between the reactor shielding and the crew quarters. Through the viewport, the Hollow stretched in every direction, a field of absolute black dusted with the faint, cold pinpricks of distant suns. The PRAETOR moved through it at a quarter standard cruise, her keel tilted slightly upward as if climbing toward something unseen. Rourke had served aboard her long enough to feel her motion in the soles of his boots, a constant low vibration that thrummed through the deck plates and into the bones of his feet.

The pulse came again. Three seconds of carrier signal, three seconds of silence, then three seconds again. Not random scatter. Not the thermal chatter of a distant gas giant. Something structured. Something deliberate.

Rourke pulled his datapad from the magnetic clip at his belt and brought up the long-range feed. The waveform scrolled across the screen in pale green, its peaks too regular, its troughs too even. He had spent eleven years reading sensor traces in the deep survey corps before Marshal Thane Rourke pulled him back to the gun crews and gave him a uniform with silver piping. He knew what background radiation looked like, and he knew what it did not look like.

This was not background.

He tapped the comm stud on his collar. "Holt. Maren. Sensor bay."

A brief pause, then her voice came back crisp and uninflected. "I see it."

"On your way or already coming?"

"Already coming. Three minutes."

Rourke keyed the bay door open to wait for her. The corridor beyond was empty, lit by the PRAETOR's standard amber, and the air carried the familiar mineral tang of recycled atmosphere mixed with the sharper note of coolant vapor. Somewhere aft, a hydraulic line ticked in its housing. The PRAETOR was a compact gun-ship, one of fourteen that the Compact had committed to the Hollow expedition, and she was old enough that her joints spoke when the pressure changed. Rourke had learned most of those voices by heart.

The pulse cycled through again. Three, three, three. He watched the trace on his datapad and felt the hair rise along the back of his neck, a primitive response his training had never quite drilled out of him. In the survey corps, a repeating signal from a sector marked empty on every chart was either a beacon or a warning. He had learned the difference the hard way, halfway through his seventh tour, when a science vessel ahead of his own had followed a rhythmic chirp into a debris cloud and stopped transmitting.

Holt arrived in two minutes and forty seconds. She came through the bay door in her blacks, hair pulled back tight against her skull, already holding her own datapad as if she had been awake and working before he called. Her eyes went straight to the viewport, then to the sensor stack, then to him.

"Source bearing," she said. "Zero three seven mark two one five. Range, estimated one-point-four million kilometers. The angle places it on our projected track, eighteen hours out at current velocity."

Rourke nodded slowly. "Rhythmic."

"Three-second intervals. Consistent amplitude. Consistent frequency. Consistent phase." She was reading off her pad, her voice the same tone she used for reactor checks and ammunition tallies. "This is not natural. This is not a station beacon. I have queried the registry twice."

"What did the registry return?"

"Nothing."

He looked at her. She looked back at him, her expression unreadable.

"Nothing means it is unregistered," she said. "Or it means the registry has been edited. Either possibility is a problem."

Rourke leaned against the sensor housing. The metal was cool against his shoulder blades. The PRAETOR hummed around them, her decks vibrating with the slow churn of the drive. From somewhere deep in the ship, he heard the distant thud of a magazine door cycling shut, the sound Kael Voss would be making as he walked the gun crews through their morning rotation. Voss had a way of moving through the PRAETOR that left a trail of mechanical noise, a habit from his years flying deep-space survey birds where every sound meant something.

"Get it on the Warden's screen," Rourke said.

Holt's mouth tightened almost imperceptibly. She did not enjoy bringing things to the Warden. None of the senior staff did. The Warden occupied a chamber at the heart of the Meridian, the station that orbited at the center of the Hollow, and it received reports through a relay that no engineer on the PRAETOR had ever been able to fully map. When the Warden answered, it answered in its own time.

"I have already pushed the packet," Holt said. "I pushed it when the third cycle came through."

"Anything back?"

"No."

The pulse came again. Three, three, three. Rourke watched the trace scroll across his datapad, the green peaks marching in their patient rows. He thought of Juno's nursery back on the Meridian's inner ring, where she would be sleeping in a rack wired with soft sensors, her chest rising and falling with the same patient rhythm. She had been three weeks old when the expedition departed, small enough that Rourke could cradle her in one arm, though he had not held her often. Juno lived with her mother in the family quarters, and Rourke visited when his rotation allowed. He had visited four times since the PRAETOR made orbit around the Hollow's anchor point.

He wondered if the relay to Juno's nursery would carry this pulse. He wondered if it would reach her.

"There," Holt said quietly.

The Warden's reply arrived as a single line of text on both their datapads. No header. No signature block. No timestamp.

ANOMALY. NO ACTION. MAINTAIN COURSE.

The characters were blocky and gray, the color the relay always used for the Warden's responses. Holt read hers first, then looked at Rourke. Her jaw was set.

"That is the same response it gave the Harrier six days ago," she said. "Anomaly, no action. The Harrier pushed closer. The signal stopped. The Harrier pushed farther. The signal stopped again. They came about and went silent on the relay for nineteen hours."

"I remember."

"The Warden sent the same packet. Anomaly. No action."

"And the Harrier kept its course."

"Yes."

Rourke set his datapad down on the sensor housing. The pulse came through again, measured and patient, and he let it fill the bay for a long moment before he spoke.

"Pull the forward optical feed," he said. "Anything visible at the source bearing?"

Holt worked her pad for a few seconds, then turned it so he could see. The optical array on the PRAETOR's bow was not designed for fine imaging at this range, but it caught light. The screen showed a smear of pale pixels against the absolute dark, a faint smear that might have been a star cluster or a dust cloud or something else entirely.

"I cannot resolve it," Holt said. "Too far. The optics top out at four hundred thousand kilometers for anything smaller than a small moon."

"Thermal?"

"No signature consistent with a hull. No signature consistent with a drive plume. Whatever is out there is either cold or it is running dark."

Rourke looked at the smear on the screen. He thought about the Harrier going silent on the relay for nineteen hours. He thought about Juno's nursery and the soft sensors and the rhythm of a sleeping child. He thought about Kael Voss moving through the PRAETOR's magazine decks, checking every bolt and feed by hand, a habit he had brought with him from his years flying the deep survey birds where a missed fault could leave a crew floating in the black.

"Log it," Rourke said. "Full packet. Source, bearing, range, waveform, the Warden's response. Timestamp everything to the second."

Holt was already typing. Her fingers moved across the pad with the quick, certain rhythm of someone who had been trained to make records that would survive any inquiry.

"Logged," she said after a moment.

"Send a copy to the Harrier's skipper. Personal channel. Mark it for the Warden's eyes only if the relay rejects it."

"The relay will reject it."

"Send it anyway."

Holt looked at him for a beat, her expression still flat, but something behind her eyes shifted. She understood what he was doing. He was building a paper trail outside the Warden's relay. He was making sure that if the PRAETOR went the way of the Harrier, someone would know the signal had been there.

"Acknowledged," she said.

The pulse came again. Three, three, three. Rourke straightened up from the sensor housing and rolled the stiffness out of his shoulders. The PRAETOR hummed around them, her decks vibrating with the slow churn of the drive, her joints ticking in their housings, her corridors waiting for the next order.

He keyed his collar again. "Voss. Gun deck. Marshal Rourke."

A pause. Then Kael Voss's voice, rough and unhurried, came back over the channel. "Voss here. I am elbow-deep in the port recoil housing. Whatever it is can wait until I finish this seal, or it cannot."

Rourke allowed himself the ghost of a smile. "It can wait. But I want a full gun check within the hour. Both turrets. Live feed on the forward optical when you are done."

A longer pause. Voss was reading between the lines, the way he always did. He had spent enough years flying the deep survey birds to know what a gun check meant when there was nothing on the scope.

"Understood," Voss said. "Forward optical. Full gun check. One hour."

The channel clicked closed. Holt finished her entry and looked up at Rourke.

"The Warden will notice the gun check," she said.

"Yes."

"The Warden does not like changes to the rotation."

"No."

Holt held his gaze for a moment, then nodded once, sharply, and turned back to her pad.

The pulse came through again. Rourke watched the trace on his datapad, the green peaks marching in their patient rows, and listened to the PRAETOR breathe around him. He thought of the smear of pale pixels on the optical feed. He thought of Juno's chest rising and falling in the nursery. He thought of Marshal Thane Rourke, who had sent him back to the gun crews and given him a uniform with silver piping, and who was somewhere on the Meridian's inner ring at this moment, likely asleep, likely dreaming of nothing.

The pulse came through once more. Three seconds on. Three seconds off. Three seconds on. A rhythm older than the PRAETOR. A rhythm older than the expedition. A rhythm that someone, or something, was sending out into the black with the patience of a thing that had been waiting for a very long time.

The engineering bay occupied the PRAETOR's ventral hull, two decks down from the CIC and one up from the magazine. Kael Voss found it half-lit when he came through the hatch, the overheads dimmed to amber standby, the long workbench running down the spine of the compartment cluttered with the detritus of three previous calibrations no one had finished. A bank of diagnostics blinked green along the far bulkhead. The air tasted of cold metal and old solder, with the faint sweetness of coolant vapor leaking somewhere behind the conduit rack. The deck hummed beneath his boots. Everything on the PRAETOR hummed beneath his boots.

He set his kit on the bench, unclasped the forward sensor interface panel, and pulled the raw feed. His wrist-comm synced to the suite in under a second. The optical array, the thermal grid, the lidar cluster, all of it spooled up in tidy columns on his cuff. He ran the prescribed handshake, confirmed the gimbal tolerances, and began the slow arithmetic of recalibration: pitch axis, yaw axis, parallax offset, drift compensation. Routine work. Work he could do half-asleep, which was the only kind of work his body wanted at 0347.

He had been a survey pilot for nine years before the Compact pulled him back and gave him a gunner's berth. He had charted eleven systems, named two of them after things he would never speak of, and learned that the black was older and emptier than any chart could hold. He had also learned that the things in the black did not always stay where you left them. Some of them followed you home. Some of them sent you signals you were not supposed to notice. The survey corps had a word for that. They called it contact fatigue. He had his own word for it, but he kept it where he kept the rest of his past.

The recalibration took twenty-two minutes. He signed the log on his wrist, forwarded it to Holt's console with the routing tag Holt preferred, and was reaching for his kit to close up the panel when the feed hiccupped.

Not a dropout. A pulse. A faint, regular pressure in the raw data that the diagnostic routines had been filtering out as noise. He frowned, tapped his cuff to pull the unfiltered stream, and held his wrist up to the dim amber light.

Numbers. Not quite numbers. A string of figures marching across the raw buffer in a pattern that did not look like noise, because noise did not repeat. Noise did not have cadence. This had cadence. Three pulses short. Three pulses long. Three pulses short. Then a gap. Then it began again.

He turned away from the bench and leaned against the conduit rack, watching. The string resolved on his cuff into something that looked, against all reason, like a heading. Degrees. Minutes. Seconds of arc. A coordinate expressed the way a navigator expressed one, stripped of clutter, the bare bones of a position in space. The first set pointed back toward the Meridian's inner ring, toward the inhabited decks, toward the nurseries and the mess halls and the Warden. A meaningless fix. A ping off the ship's own structure.

The second set was different.

He stared at it. He ran the conversion twice, by hand, the old survey corps way, because his hands knew the math before his head did and he did not want the cuff's software to round anything off. Fourteen degrees off the PRAETOR's declared heading. Fourteen degrees off the course Holt had entered into the nav console an hour ago. Fourteen degrees toward a point in the Hollow that the PRAETOR's charts did not mark, because there was nothing there to mark.

He let his hand drop to his side. The engineering bay breathed around him, the coolant leak ticking somewhere behind the rack, the diagnostics blinking their patient green. The feed on his cuff kept scrolling, the second coordinate string repeating itself with the regularity of a heartbeat, three on, three off, three on. He watched it for the length of a full minute without moving. He watched it for a second minute. The string did not change. The fourteen-degree offset did not waver. Whatever was sending it was not drifting. Whatever was sending it knew exactly where the PRAETOR was, and it knew exactly where the PRAETOR was not going.

He thought of Sera.

He thought of her the way he always did when something on a scope did not add up, which was to say he thought of her as a fixed point, a weight on one side of a balance. On the other side was whatever was making the pattern, whatever was out there in the black at fourteen degrees off the plotted course, broadcasting a position to a ship that had not asked to be addressed. He had promised himself, a long time ago, in a station corridor that smelled of recycled air and old metal, that he would not let the survey corps follow him into his new life. He had broken that promise twice already. He was about to break it a third time.

He pulled the raw buffer off his cuff and saved it to the local engineering drive, encrypted, tagged with a personal routing code that did not belong to anyone on Holt's crew list. Then he cleared the wrist display, shut the interface, latched the panel, and stood for a moment with his hands flat on the workbench, breathing the coolant-sweet air in through his nose and out through his mouth, the way the survey corps had taught him to breathe when the scope showed you something you did not want to see.

Fourteen degrees. Not a drift. Not a reflection. A deliberate vector, aimed at a coordinate the PRAETOR was not flying toward. Which meant either the PRAETOR's declared heading was wrong, or someone, or something, was inviting the PRAETOR to change it.

He picked up his kit and walked toward the hatch. He needed to get to the CIC. He needed to put the buffer on Holt's screen before Holt noticed the gun check had finished and started asking why his wrist-comm had not synced clean. He needed to do it without telling Holt what he thought the pattern was, because Holt would not believe him, and if Holt did believe him, Holt would have to tell Rourke, and Rourke would have to decide what to do with a fourteen-degree invitation from something that should not exist.

The hatch hissed open. The corridor beyond was dark, the standby lamps running their dim blue night cycle, the deck plates cool under his boots. He stepped out and let the hatch seal behind him, and the engineering bay settled back into its quiet hum, the diagnostics blinking green, the coolant ticking behind the rack, the raw buffer sitting in its encrypted slot, waiting to be read by someone who would have to decide whether the PRAETOR answered the call or kept its course.

He walked. The corridor stretched ahead of him, lit in thin blue strips, and he counted his steps the way he always counted his steps on a dark ship at night, because counting was a way of staying in the present tense, and the present tense was the only place he was willing to live.

The deck plating thrummed beneath Rourke's boots, a low and constant note that traveled up through the soles of his feet and into the bones of his shins. He kept one hand flat against the bulkhead, fingers trailing the seam line, and he had counted seven hundred and twelve rivets between the engineering bay and the auxiliary spine. He had not decided to count them. The counting had decided itself, the way it always did on a dark ship at night, when the only way to stay inside a single tense of the verb was to make every step a small and measured thing.

The temperature dropped as he crossed from B deck to C. The auxiliary spine ran cool even at station-keeping. Condensate beaded on the seams of the overhead and fell in thin silver threads to the deck plates, where it pooled in the treads of the mats and gave the air the taste of cold metal and ozone. Somewhere above him, in the dark, a transformer hummed louder than it should have. Rourke marked the sound and kept moving. He had eleven minutes. Twelve, if Holt had stopped for her second cup of tea. Holt never stopped for her second cup of tea. Holt had not stopped for a cup of anything in the seven years he had known her, and he had known her long enough to know that her second cup was a myth she told Rourke about so he would think she drank tea.

At the junction outside the maintenance hatch, he slowed.

The maintenance hatch was a slung thing, set into the spine on the cargo hold side. It was the kind of access nobody used after twenty-one hundred unless they were running cargo they did not want logged in the night ledger. The deck lamp above it had been broken for a week. The replacement filament was a mil-spec part that had not yet come down from the quartermaster's stores, and the patch job on the housing had left the bulb exposed to the humid air of the spine. The light it gave off was the color of old bone.

Someone was standing under that light.

Rourke's hand went to his belt before his eyes finished focusing. The figure had its back half-turned. Kit in the left hand. Portable buffer in the right. The shoulders were wrong for Holt. The shoulders were wrong for anybody on the Warden detail. The shoulders were the shoulders of Kael Voss.

"Skipper."

Kael's voice was low, respectful, slightly hoarse around the edges. Rourke heard the hoarseness and understood it, the way he always understood the small injuries in the voices of the men who had walked dark corridors on his ship for years. Kael was hoarse because he had been arguing with himself for some time, and arguing with yourself used up the throat.

"I was bringing the buffer up to the CIC." Kael nodded toward the dark ahead, toward the CIC and the gun station and the empty chair where Holt would be sitting when she finished her sweep of the gun check logs. "Holt's sweep just ended. I heard her seal the chair. She'll be on the main screen in two minutes."

"Then walk," Rourke said. "Don't talk. Move."

"I can't."

Kael said it the way he said most things, in a single short sentence with no ornamentation on it. His eyes were on the cargo hold hatch.

"I can't move until Holt is out of the corridor," Kael said, "because Holt is not coming from the CIC. Holt is over there."

He tilted his head toward the cargo hold hatch. The hatch was sealed. The night log said it had been sealed at twenty-one hundred, sealed by the off-going bosun, sealed with the standard magnet pattern. The access port in the hatch was dark. The catwalk behind it was dark. The cargo hold was dark all the way down to the bilge, and the dark was the kind of dark that swallowed footsteps whole.

But in the dark, at the far edge of the port, a figure was moving.

The figure moved with the particular economy of someone who had been trained to cross a ship without leaving a trace of her passage. Rourke had known only three people in his career who could move like that. One of them was dead. One of them was in the brig on a station three systems over. The third one dropped from the catwalk to the deck and stood under the broken bulb and was breathing hard enough that Rourke could hear the wet catch at the back of her throat.

Maren Holt.

She looked at Rourke. She looked at Kael. She did not speak. She crossed the deck in four strides, came up to the two men under the broken bulb, and opened her hand.

In her palm, small and silver, was a data chip.

"Six weeks," she said. Her voice was clipped, each word bitten off at the edges the way she always bit her words when she was running on procedure rather than sleep. "Six weeks of sensor drift. Logged by my own hand. On my personal device. Off the ship's network."

She held the chip out, and she held it out to Kael, not to Rourke, and Kael took it before Rourke could make the decision about whether to let him take it.

"Unofficial observation log. Don't read it on a ship terminal."

She said it without inflection, without emphasis, without the rise at the end that would have made it a request. She said it as a fact, the way she said every fact, the way she had reported the loss of her first command, the way she had written her own fitness report at the end of the watch, the way she would have read her own eulogy if the service had been willing to bury a Holt without a list of her accomplishments.

Then she was gone.

She did not run. Running made noise. Holt had never made noise in her life unless the noise was required. She dropped below the catwalk rail, caught the first rung, slid down it, and was swallowed by the dark of the hold. The deck plating did not vibrate under her weight. The night log, when it was queried in the morning, would show that Maren Holt had been in her quarters from twenty-one hundred until oh-five-thirty. The night log would show this because Maren Holt had written the night log herself, and Maren Holt was very, very good at writing the night log.

Rourke looked at Kael.

Kael was holding the chip between his thumb and forefinger, and the buffer was humming in his other hand, and his knuckles were the color of candle wax.

"Skipper," Kael said, "I need to get this off the ship."

"No."

"Skipper, if this is what I think it is, this cannot stay on the Meridian. If Holt logged six weeks of drift on her own device, that means the ship's logs do not show it. The only way the ship's logs do not show six weeks of drift is if somebody on this ship is scrubbing the logs. The only way the scrubber would not have caught Holt's own device is if Holt knew about the scrubber. The only way Holt would have known about the scrubber is if she trusted somebody on this ship enough to spend six weeks collecting evidence on a chip she could fit inside a thimble."

"Kael."

"Skipper, this is not a survey report. This is someone on this ship changing what the ship sees, and Holt is the only one who noticed, and the Warden has been on board for nine days without a logged boarding. I have done the math, Skipper. I have done the math twice. The numbers do not work unless somebody on this ship is deciding what the ship remembers."

Somewhere above them, a patrol drone disengaged from its cradle with the

Somewhere above them, a patrol drone disengaged from its cradle with the soft click of magnetic locks releasing. Its navigation light pulsed once, twice, then it slid down the corridor on its guide rail, indifferent to the two men standing below with a chip that should not exist and a buffer that should not be needed.

Rourke watched the drone pass. He watched it the way he had been trained to watch things in small rooms when the air had grown heavy and the next words spoken would be the ones that could not be taken back.

"Kael," he said.

"Skipper."

"Put the chip down."

"Skipper."

"Kael. Put it down."

Kael set the chip on the workbench beside the buffer. His hand came away slowly, as if he were setting down something that might detonate. He did not step back from it. He left his palm hovering a centimeter above the surface, the heat of the chip warming the air between his skin and the polymer.

Rourke picked up the chip. It was smaller than he had expected. Cool to the touch. The kind of object a person could lose in a ventilation duct and never find again. He turned it once in his fingers, watching the data light pulse in its slow, patient rhythm.

He set it back down.

"You are asking me," Rourke said, "to confine my chief navigator on the basis of a chip you found in a place she should not have been, using a buffer that somebody may or may not have given you."

"I am asking you, Skipper," Kael said, "to read what is on the chip before you decide what to do with it."

"I have read what is on the chip."

"Then you know."

"I know that somebody has been scrubbing this ship's memory for at least six weeks. I know that the scrub pattern is precise and methodical. I know that the chief navigator logged herself in her quarters for the relevant hours, and that her log entries are clean." Rourke let the silence stretch one beat. "I also know that Maren Holt has served this Compact for nine years, has pulled this crew out of three incidents I would not have wished on my worst enemy, and has never once given me reason to doubt her loyalty."

"Until now," Kael said.

"Until you found a chip."

"Until I found a chip and a buffer that should not exist in the same room."

Rourke looked at the buffer. It was a survey corps model, gray-polymer cased, with a recessed screen and a single data port. He had not seen one in nearly a decade. He had not expected to see one again.

"Where did you get this, Kael?"

"It was in my sea chest."

"In your sea chest."

"Yes, Skipper."

"Since when?"

"Since before I came aboard."

"Before you came aboard."

"Yes, Skipper."

Rourke waited. The patrol drone had reached the end of the corridor and turned. Its navigation light pulsed against the far bulkhead, a slow heartbeat in the small room.

"Explain that," Rourke said.

Kael's jaw worked once. The movement was small, almost invisible, but Rourke had known Kael Voss for long enough to see the muscles bunch beneath the stubble.

"When I left the survey corps," Kael said, "I did not leave cleanly. There were things I had collected. Records of things I had seen. Things I was told did not exist and that I had not seen, and that the corps did not wish for anyone to have seen." He paused. "I kept them. I kept them because I am the kind of fool who keeps things. I kept the buffer because the buffer was the only way to read what I had kept. I have not used either in nine years. I have not thought about either in nine years. I have not wanted to think about either in nine years."

He looked at Rourke.

"Until tonight."

Rourke said nothing. The chip pulsed on the workbench. The buffer hummed. Somewhere in the hull, the Meridian breathed the long, slow breath of a ship that had been sailing for longer than any of them had been alive.

"Kael," Rourke said. "I want you to listen to me very carefully."

"I am listening, Skipper."

"If I confine Holt, and you are wrong, I have destroyed the chain of command on this ship on the eve of an engagement I do not yet fully understand. I have also made an enemy of the woman who keeps the Meridian in one piece, and I have done it on the basis of a chip, a buffer, and your word."

"Yes, Skipper."

"If I do not confine Holt, and you are right, I have allowed a compromised officer to remain at her post during a period in which the ship's logs cannot be trusted. I have also allowed her to continue whatever she has been doing for six weeks, and I have done it for the sake of procedure."

"Yes, Skipper."

"So I am going to do the third thing."

Kael's eyes narrowed. "What is the third thing, Skipper?"

"The third thing," Rourke said, "is that I am going to confine neither of us. I am going to ask Holt to come down here. I am going to put the chip on this workbench between us. I am going to ask her, in front of you, what is on it. And I am going to watch her face while she answers."

Kael considered this. The consideration took longer than Rourke had expected.

"And if she lies," Kael said.

"Then I will know she is lying."

"And if she does not lie."

"Then I will know what is on the chip. And I will know who to trust."

Rourke reached for the comm panel on the bulkhead. He keyed it once, twice, then held the transmit key down.

"Holt."

A pause. The channel hummed.

"Marshal." Maren Holt's voice came back clean, crisp, with no surprise in it. "I read you."

"Navigator, I need you in auxiliary three. Now."

"Acknowledged. En route."

The channel closed. Rourke let his hand fall from the panel.

He looked at Kael.

"If you are wrong about her, Kael, this conversation is going to end very badly for both of us."

"Yes, Skipper."

"If you are right about her, this conversation is going to end very badly for all of us."

"Yes, Skipper."

"Then we wait."

Rourke turned the chair at the workbench and sat. He did not pick up the chip. He did not pick up the buffer. He folded his hands on the workbench and watched the door, and he waited for the sound of Holt's boots in the corridor, and he thought about a ship that remembered what it was told to remember, and a navigator who had been writing her own log for six weeks, and a warden who had come aboard without a logged boarding, and a nursery at the bow where a child was listening to a signal that no one aboard had yet explained.

The patrol drone completed its circuit and began another. Its navigation light pulsed against the bulkhead, a slow and patient rhythm, like the heartbeat of something that had been waiting a very long time for this exact moment.

The boots in the corridor were coming closer.
