The buoy chain drifted past the starboard observation blister in a slow, revolving constellation of corroded metal. Each marker pulsed a weary amber, out of sync with its neighbors, as though the equipment had been cannibalized and reassembled by hands more concerned with salvage than signaling. Beyond the chain, the Marchward Arm opened into a sprawl of tumbling rock and frozen dust, the kind of geography that swallowed patrol routes and spat out bones.
Heth Rowant stood with one boot hooked against the viewport's lower rail, watching the last buoy tumble away. His breath fogged the inner glass in slow, deliberate plumes. The Iron Silence's bridge smelled of recycled air and the faint mineral tang of the coolant leak that Pell Aronos had been chasing for three days. Neither smell belonged to a ship that was supposed to be running quiet.
"Buoy chain is behind us," he said. "Logged and noted."
Pell's voice came from the auxiliary console, dry as the dust on the observation port. "Logging that we logged it. Very recursive. The regime would be proud."
"Quiet," Heth said.
The word was not a reprimand. It was a warning. Beyond the viewport, a cluster of mining rigs clung to a tumbling chondrite the size of a city block, their lamp arrays winking red against the rock's pitted surface. The rigs were unlicensed, their transponders squawking pirate frequencies. Two of them had hull markings that Heth recognized from the briefings Maren Vex had pushed to his tablet six days ago: the skeletal hand holding a neutronium coin. Smugglers. Openly operating in the contested Arm, daring the patrol frigates to come close enough to be embarrassed.
He keyed the internal channel. "Yenna. Status on the Quietude."
"Translation: still pretending to be a rock," Yenna Aros replied, her voice carrying the particular boredom of a signals officer asked the same question twice in one watch. "Their emissions profile is consistent with a derelict hauler. If you squint."
"They paid for that profile," Heth said.
"They paid for a lot of things," Yenna replied. "Some of them were even legal."
Heth killed the channel and let his forehead rest against the cool glass. The viewport's chill bled through the plating of his skull. Somewhere behind him, Vessa Linn was cataloging the cargo manifests for the third time that watch, because she did not trust the auto-counter, because she had once lost a hold full of medical isotopes to a rounding error, and because she believed, with the quiet fervor of a woman who had been failed by machines, that a human eye was the only instrument worth trusting.
He pushed off the rail and crossed to the auxiliary plot. The holo-table woke reluctantly, its projection lattice flickering blue over the tactical overlay. The Marchward Arm spread across the display in a snarl of vector threads and threat gradients. Red zones marked recent patrol activity. Amber zones marked the contested fringe. The Iron Silence's intended course threaded through the amber like a needle through cloth.
Pell leaned past him and tapped two zones along the upper margin. "Mining cooperative Three-Finger has a buyer for neutronium cores," she said. "They're operating out of a stripped bulk hauler called the Curfew Bell. If we're going to be moving through their territory, it might be worth knowing what they're willing to sell."
"We're not here to shop," Heth said.
"No," Pell agreed. "But Maren Vex would want us to know what's on the menu. In case the menu changes."
The name landed in the bridge air with a particular weight. Maren Vex had sent them into the Marchward Arm with a route, a cover story, and a single instruction: do not attract attention. The instruction had not been repeated. It did not need to be. Maren Vex's instructions had a way of becoming obvious only after they had been broken.
Heth pulled up the secondary plot and overlaid the mining cooperative's last known positions. Three-Finger's rigs clustered around a tumbling carbonaceous body in the upper Arm, their lamp arrays synchronized in a slow, hunting rhythm. The Curfew Bell, according to the intercept Pell had pulled two days ago from a regime administrative channel, was operating as a floating market. Neutronium cores moved through her holds in unmarked crates. The buyers paid in cryptocurrency, in labor chits, in favors. The sellers accepted almost anything that did not fluoresce under a customs scan.
"Vessa," Heth said over his shoulder. "How's the count."
"Stable," Vessa Linn answered without looking up from her station. "Forty-one crates of graft tissue, twelve of neural scaffolding, eight of the unmarked pharmaceuticals. The auto-counter agrees with me this time. I have apologized to it."
"Apology noted," Heth said.
"I also found a discrepancy in the ballast logs," Vessa continued, her stylus tapping against the edge of her console. "Eighteen kilograms of inert mass registered against hold four, but the hold's actual mass signature is short by nineteen kilograms. Someone has been sneaking weight off the ship."
The bridge cooled by another degree.
"Nineteen kilograms," Pell said.
"Approximately," Vessa said. "Give or take the error margin of an instrument that has been lying to me for a week."
Heth turned the discrepancy over in his mind. Eighteen logged, nineteen missing. The difference was not large enough to be cargo. It was large enough to be a device.
"Scan the hold," he said.
"I have scanned the hold," Vessa replied. "Three times. The scan reads the eighteen kilograms it expects to find. The scan is wrong."
"Then we go in person," Heth said.
"Noted," Vessa said. She closed her manifest with a final tap and rose from her station. Her boots made no sound on the deck plating. She moved like a woman who had learned, in some earlier life, how to occupy space without disturbing it.
Pell watched her go and then turned back to the holo-table. "She's going to find it," she said.
"She's going to find something," Heth corrected.
Pell did not argue the distinction. She pulled up the mining cooperative's traffic logs and began marking the rigs that had transacted with the Curfew Bell in the last standard week. Twelve vessels. Four of them had hull histories that intersected with regime blacklists. One of them, a prospector called the Cold Witness, had been flagged in an Odera Quill intercept as a possible courier for a sabotage cell operating out of Lethe-9.
"Odera," Heth said, keying the cipher channel.
A pause. Then a voice, smooth and slightly nasal, arrived in his earpiece with the particular crispness of someone who had been waiting to be asked. "Captain Rowant. I was wondering when you would call."
"The Cold Witness," Heth said. "Tell me what you have."
"I have four intercepts, two of which are contradictory, and a third that is probably a plant," Odera Quill said. "The fourth is a cipher I have not yet broken. It may be nothing. It may be a grocery list. Cipher analysts do not editorialise."
"Editorialise anyway," Heth said.
"The Cold Witness has been making runs into the Marchward Arm for the better part of a year. Her listed cargo is industrial solvent. Her actual cargo, according to a regime port authority manifest that I obtained through means I will not describe, is gravitational survey equipment. The kind of equipment one uses to map large masses at distance. The kind of equipment one uses to find things buried in asteroids. Or, for that matter, things buried in station bulkheads."
Heth let that sit for a moment.
"You think they're looking for something," he said.
"I think they're looking for something specific," Odera said. "I think the regime knows what it is. I think the Cold Witness does not. And I think the cipher, when I break it, will tell us which of those three conditions has changed."
"When," Heth said.
"I do not say 'if'," Odera replied. "If is a word for people who have not yet met me."
The channel hissed softly. Heth could hear, beneath the cipher's static, the faint percussion of a stylus against a writing surface. Odera Quill, decoding regime transmissions in a closet-sized archive somewhere in the Belt, surrounded by paper that would not exist if the regime had its way.
"Keep me posted," he said.
"I will keep you posted when there is something to post," Odera said. "Until then, I suggest you watch the Curfew Bell. Neutronium cores are heavy. They bend sensor returns in interesting ways. If someone is hiding something on your ship, Captain, the Curfew Bell is the sort of place they would have bought it."
The channel closed. Heth stared at the holo-table for a long moment, watching the red and amber zones drift against each other like the colors of a bruise.
Pell broke the silence. "She's not wrong about the cores."
"No," Heth said.
"Maren is going to want to know about the discrepancy," Pell said.
"Maren is going to want to know about everything," Heth replied. "That is the problem with being the one who knows everything."
Pell made a small, noncommittal sound and turned back to her console. The holo-table hummed its low, working hum. Beyond the observation blister, another buoy chain drifted into view, this one denser, its markers pulsing a sickly green. The boundary of the mining cooperative's claimed territory. Past it, the rock was thicker, the dust was darker, and the patrol frigates came less often.
Heth watched the green markers revolve and thought about eighteen kilograms of inert mass and a cipher that might be a grocery list.
Pell touched her earpiece and tilted her head, the gesture of someone listening to a frequency only she could hear.
"Skipper," she said. "We have a contact."
Heth crossed to the holo-table in three strides. The tactical overlay bloomed outward in pale blue lines: the Iron Silence's projected course, the slow drift of the buoy chains, the dim constellations of cooperative mining claims. A new marker pulsed red at the edge of the sensor grid, far ahead and slightly above the ecliptic.
"Identification," he said.
"Unconfirmed. Profile reads as a derelict. No transponder. No life signs. Hull matches a Belt hauler configuration, possibly a Colmar-class ore carrier from the second reclamation surge. She's dark and cold and she's been adrift for a while."
"How long?"
"Months. Maybe longer. The hull's radiation profile is cold enough that she could have been there since before the Curfew."
Before the Curfew. Before the Sovereign Combine finished consolidating the Belt and started enforcing its claim with patrol frigates and kill-orbits. Heth filed the date away the way he filed most history now: a fact that mattered only insofar as it affected the present.
"Who spotted her?"
"Yenna, on the optical sweep. She was running the secondary array for occlusions behind the rockfalls and the profile popped out against a nickel-iron signature. The contrast was unusual, so she flagged it."
Yenna Aros had the eyes for that kind of work. She had been an observatory technician on Callisto before the Combine nationalized the gas giants' research installations and put her out of a job. Now she lived in a converted instrument bay on the Iron Silence and ran optical sweeps with the patience of someone who had once spent months tracking the orbital decay of a single ice moon.
"Can we hail her?"
"No response. No surprise there. But the profile is solid enough for a boarding. If there's anything worth salvaging in her holds, we should take a look before a patrol frigate does it for us."
Heth studied the contact marker. The derelict sat in the seam between two patrol routes, in a zone the cooperative claimed but did not enforce. If the Iron Silence altered course to investigate, she would lose two days on the rendezvous with Maren Vex's contact at Veyren's Hollow. If she did not investigate, the next Combine frigate to drift through the area would find the wreck and its contents both.
"Log it," he said. "Mark it for Maren. And put a tightbeam to the Curfew Bell. Odera will want to see what we find."
"She's going to want to come along," Pell said, with the careful neutrality of someone stating an observation she had no intention of defending.
"She's going to stay on the Bell where she's useful," Heth said. "Tell her to prep the cipher suite. If we find any Combine cores, she'll be the one decrypting them."
The boarding prep took an hour. Heth suited up in the aft lock with two of the deckhands he trusted most: a Belter named Rusk who had grown up in the vacuum mines of Proserpina and could read a hull stress pattern the way Odera read a cipher, and a quiet spacer called Tem who had been with the Iron Silence since before Heth took command and who never volunteered information about his past. The three of them cycled through the lock in silence, the air hissing out of the chamber with the particular smell of recycled breath and warm metal that Heth had learned to associate with the moment before a boarding.
The derelict loomed against the rock. Her name was painted on the stern in faded blue letters: the Bitter Promise. The paint had curdled in the vacuum, and what had once been a crisp corporate font now looked like a bruise. Her running lights were dead. Her comm array was a skeleton of bent metal. A single porthole near the bow had been welded from the outside, which suggested that someone had locked something in, or something had locked itself in, and the difference mattered in the Belt.
Rusk mag-locked to the hull and ran a gloved hand along the seam of the airlock.
"She was breached," he said, his voice flat over the suit radio. "See the scarring? Micro-meteorite strike, port side, midships. They patched it with a manual weld. Sloppy work. Sloppy or rushed."
"Rushed," Tem said. He pointed to a pattern of small impact craters clustered around the patch. "The weld went in before they patched the hull. They welded it under pressure. That means they had atmosphere they wanted to keep."
Heth studied the patch. Tem was right. The weld had been laid from the inside, in atmosphere, then the hull had been patched from the outside in vacuum. That was the order of operations for a crew that had been in a hurry to contain something they did not want to vent.
"Open it," Heth said.
Rusk cut the lock with a plasma torch. The metal shrieked and spat, and the airlock irised open with a groan that Heth felt through his boots as much as heard. The interior was dark. The emergency lighting had failed. The air was thin and stale, the kind of cold that came from a ventilation system that had stopped circulating years ago and a hull that had slowly bled its warmth into the rock.
They crossed the threshold into the Bitter Promise's main corridor. Heth's helmet lamp swept across peeling paint, bundled cabling, and a long smear of something dark and dried that he did not let himself identify.
"Galley," Tem said, pointing forward. "Crew quarters aft. Cargo holds below."
"Cargo holds," Heth said.
The ladder to the lower deck was rusted but intact. Heth went first, his boots ringing on the rungs, the suit servos whining faintly with each step. The cargo hold opened into a wide bay stacked with ore containers, most of them sealed, a few of them split open and emptied. The smell that rose to meet him was mineral and stale and faintly chemical, the way an old mine smelled after the lights had been out for a season.
He swept the bay with his lamp. The containers were stamped with the logo of the Callisto Mining Cooperative, which had been absorbed into the Combine's industrial portfolio three years ago. Most of the manifest codes had been scratched off, but the container nearest the bay door still bore a faded inventory tag. Heth read it twice, then read it a third time to be sure.
"Pell," he said, opening the suit channel. "Are you receiving?"
"Receiving, Skipper."
"The cargo manifest on this derelict references a neutronium shipment. Eighteen kilograms. Bound for the cooperative's refinery at Veyren's Hollow."
A pause. He could hear her breathing through the channel.
"That's the same mass that Odera flagged on the manifest Maren gave us," Pell said.
"Yes."
"And it's bound for the same refinery that the contact at the Hollow is supposed to meet us at."
"Yes."
"That's a coincidence, Skipper."
Heth did not answer. He crossed the bay to the container and ran a gloved hand along its seal. The seal was intact. The container was cold. Whatever had been in it was still in it, or had been removed and replaced with something that weighed the same.
"Open it," he said.
Rusk cut the container seal with the torch. The lid groaned upward. The smell that came out was sharp and metallic and older than the ship. Rusk aimed his lamp into the interior and swore, softly and with feeling.
The container was full of Combine targeting cores.
They were stacked in neat rows, each one the size of a small suitcase, each one stamped with the stylized eye-in-star logo of the Sovereign Combine's Strategic Targeting Directorate. Heth counted them by sight. Forty-seven. Forty-seven cores, each one containing targeting algorithms sophisticated enough to guide a frigate-class vessel through an asteroid field at relativistic speeds.
"They're not live," Tem said. He had reached into the container and lifted one of the cores, turning it over in his gloved hands. "See the plating? These are reference units. Demonstration hardware. The kind of thing the Directorate sends to a prospective client."
"Prospective client," Heth repeated.
"The Combine sells its targeting algorithms to the highest bidder," Tem said. "They've been doing it for years. Anyone with a fast ship and a grudge can buy a kill-orbit. The mining cooperatives buy them to protect their claims. The pirate clans buy them to protect their claims from the mining cooperatives. It's a whole economy."
"And someone put a shipment of demonstration cores in an unmarked ore hauler and sent it toward Veyren's Hollow."
"Yes."
"And someone scrubbed the manifest so the cores wouldn't be flagged on the cooperative's customs sweep."
"Yes."
"And Maren Vex, who is a former intelligence operative with ties to the very same Strategic Targeting Directorate, has a contact at Veyren's Hollow who is expecting to meet my ship and an eighteen-kilogram mass that turns out to be the exact same shipment we are now standing in front of."
Tem was quiet for a moment. Then he set the core carefully back in the container.
"I would not want to be the one to tell her that," he said.
Heth closed the container lid. The seal would not hold a forensic inspection, but it would hold a casual glance from a Combine customs cutter, which was the only kind of glance this shipment was likely to get.
"Pell," he said. "Log everything. Photograph the cores, photograph the seal, photograph the manifest tag. And get me Maren Vex on a tightbeam. Now."
"She's not going to like it," Pell said.
"She is going to like it even less when she finds out we found it before a patrol frigate did," Heth said. "Patch me through the moment she answers."
He straightened up in the cargo bay of the Bitter Promise and listened to the silence of the derelict settle around him. The targeting cores sat in their neat rows in the dim light. The hull creaked softly as the rock outside shifted. The suit's CO2 scrubber ticked in his ear.
Somewhere in the seam between two patrol routes, a Combine frigate was running a sensor sweep that might, at any moment, detect the heat signature of a cutting torch on a hull that had been dark and cold for years.
Heth listened for the telltale whine of an inbound frigate's drive plasma and did not hear it. Not yet.
"Rusk," he said. "Tem. Get the cores into the transfer bags. We are taking them with us."
"If the manifest is scrubbed, the cores could be anything," Rusk said. "They could be active. They could have failsafes."
"Then we will be very careful with them," Heth said. "And we will let Maren Vex be the one to decide what to do with them."
The two deckhands began to work. Heth watched the airlock and waited for the tightbeam to connect.
He did not have to wait long. Maren Vex answered on the first pulse, which meant she had been waiting by the comm.
"Captain Rowant," she said. Her voice was flat and dry, the way an old whiskey was flat and dry, with no warmth in it and no need of any. "I trust you have news."
"I have a shipment," Heth said. "And I have questions."
"Then ask them," she said. "But ask them quickly. We are approaching the point in the schedule where I no longer have the luxury of patience."
Outside the derelict, in the dark and the dust of the Belt, the Iron Silence hung in the rock and waited for an answer to a question that had not yet been fully asked.
The tightbeam to the Iron Silence opened a channel wide enough for Maren Vex to hear the rock settle around the derelict. Heth gave her the short of it. No names, no call signs. He gave her the facts in the order she would want them: manifest scrubbed, four containers live, two cores, two plasma bottles, all under armed guard. Then he gave her the variable that changed the math.
"A Combine frigate running a sensor sweep nearby. Mine class. Lanthanum profile. They are not hunting for us, but they are hunting for something."
Maren was quiet for the length of one breath. Then two. Heth counted them the way a smuggler counted coin: precisely, and without fondness.
"You have a window," she said. "I will make sure it stays open."
The channel closed. Heth stood in the airlock for another moment, listening to his own breath. The suit's CO2 scrubber ticked. The rock outside shifted and groaned.
"Tem," he said. "How are the cores."
"Transfer bags sealed," Tem said. "Cold. Quiet. No hum I can hear."
Rusk had already begun to rig a portable beacon to the suit's antenna. The beacon would scream out a loop on the Combine's distress band, the kind of noise that sounded like a freighter tearing open in a micro-meteor storm. It would not fool a dedicated patrol for long, but it would draw eyes to the derelict for a quarter hour. In a fight between a smuggler and a frigate, a quarter hour was sometimes all you could buy.
"I want the beacon armed but quiet," Heth said. "We move first. Then we broadcast."
Rusk nodded. Heth heard the soft click of the beacon sliding into standby.
He took one more breath, then palmed the airlock's outer cycle. The door ground open. The Belt came in: dust on the glass, dust in the lungs, dust in the suit joints. The cores went into the cargo cradle. Tem and Rusk cycled out behind him. The derelict's hull sighed shut behind them.
The Iron Silence lay three kilometers away, painted in shadow and grit. Heth set his pace and held it, and the small procession crossed the rock in silence.
By the time they reached the ship, Heth's throat was dry and his legs ached in the way legs ache when the suit's cooling has been working hard. The cores were a dull weight in the cargo cradle. The rock all around was quiet.
The airlock took them in. The hull closed. Heth cycled his helmet and pulled it free, and the stale air of the Iron Silence hit his face like a hand.
"Captain on deck," Pell Aronos said, from the bridge hatch.
"Belay that," Heth said. "Tell Halden Roe I need him in the cargo bay. Now."
Pell vanished. Yenna was already at the power locker, pulling the safeties on the secondary coils. The cargo bay smelled of coolant and old grease. Vessa Linn stood by the diagnostic cradle, a coilgun round cradled in both hands like a sleeping bird.
The round was not the size of a fist. It was the size of a forearm, and it hummed faintly in Vessa's grip, the way a tuning fork hums after it has been struck. Heth looked at it and understood, in the way a man understands a thing he had not known he was afraid of, that the round was not inert.
"Is that live," he said.
"It is as live as anything I have made," Vessa said. Her voice was small, but her hands were steady. "Halden balanced the propellant mass to the milligram. The sabot is magnetically pinned. The coil will not fire without a coded arm."
"How long between arm and fire," Heth said.
"Point four seconds," Vessa said. "If the round is in the chamber. If the chamber is cold. If the coil has not been cycled more than four times in the last hour."
"And if any of those is not true," Heth said.
"Then the round goes off inside the gun, and we all have a very bad minute," Vessa said.
Halden Roe came through the bay hatch at a stride that was not quite a run, his sleeves rolled to the elbow, his forearms black with grease. He took in the room with one sweep of his eyes and stopped at the cradle.
"One," he said. "You have one of mine."
"I have one of yours," Heth said. "A Combine frigate is running a sensor sweep near the derelict. If it turns toward us, I would like to be able to answer."
Halden looked at the round. Then at Vessa. Then at Heth.
"The round will not punch a frigate," Halden said. "It was built to puncture a patrol skiff's drive housing at a thousand kilometers. A mine class is another animal."
"I do not need to kill it," Heth said. "I need it to flinch."
Halden was quiet for a long moment. He reached past Vessa and took the round, and his hands moved over it the way a parent's hands move over a child's face, checking for fever.
"Vessa," he said. "Cycle the coil once, no more. Pell, bring the arming cradle online. Yenna, give me a clear lane to the forward ventral mount."
The bay moved. Vessa cycled the coil. Pell brought the cradle up. Yenna cleared the lane. Halden slotted the round into the cradle and stood over it, and his face in the bay's working light was the face of a man who had spent a long time being careful with dangerous things, and who had come out the other side of that caution into something stranger and less forgiving.
"Captain," he said, without looking up. "If you fire this, you will be signing a letter you cannot unsign."
"Then I will sign it," Heth said.
Halden nodded, once, and went back to his work.
Odera Quill was on the bridge. She had not been told to be on the bridge, but she was on the bridge, sitting at the cipher station with her headset half on and her fingers moving across the keys at a tempo that suggested she had already heard the room and chosen her seat. Pell had given her the seat. Pell had understood, by then, that Odera Quill did not wait for permission.
"The frigate is running a passive sweep," Odera said, without preamble. "I have been listening to its emissions for the last eleven minutes. It is not broadcasting on a command loop. It is receiving on one."
"Then it is under orders," Heth said.
"Then it is under orders," Odera said. "And whoever is giving those orders is not far."
Heth crossed to the sensor station. The frigate's profile was a green smudge on the secondary plot, eight thousand kilometers off the starboard bow, drifting toward the derelict at the pace of a sleeping shark.
"Can you hear the loop," Heth said.
"I can hear a fragment of it," Odera said. "It is compressed and salted. The Combine does not trust its own officers. The salt cycles every ninety seconds."
"Break it," Heth said.
"I will need time," Odera said.
"You will have less time than you want," Heth said.
"I am aware of the math, Captain," Odera said, and the dryness in her voice was a different dryness from Maren's, thinner, sharper, with no warmth in it at all.
On the bay's ventral mount, Halden finished his work. The coil hummed at quarter power, a sound like a wasp in a jar. The round waited in its cradle. Yenna stood by the firing stud with her hand in her pocket and her eyes on the captain.
The minutes passed. The frigate closed. Odera's fingers moved. Heth watched the plot and listened to the bay, and the two sounds together, the soft tick of keys and the low hum of the coil, were the only sounds in the ship.
"Got it," Odera said.
Heth turned.
"The command frequency," Odera said. "I have it. It is on a sixteen-second pulse, encrypted, salted, and routed through a dead-drop relay at Avar Mun." She looked up from her keys. "It is the kind of frequency that does not want to be found, and I have found it anyway."
"Can you broadcast it," Heth said.
"On what," Odera said.
"On every band we have," Heth said. "Open loop. Unencrypted. As loud as we can make it."
Odera stared at him. Across the room, on the ventral feed, Halden raised his head.
"That will tell the entire sector where the Combine fleet is coordinating," Odera said.
"Yes," Heth said.
"That will also tell the Combine exactly where we are," Odera said.
"Yes," Heth said.
"And you want me to do it anyway," Odera said.
"I want you to do it," Heth said. "Maren Vex will make sure the signal is heard by the people who need to hear it. The Combine will hear it too. That is the price."
Odera was quiet for a moment. Then she pulled her headset down over her ears and turned back to the keys.
"Halden," Heth said, on the internal. "Arm the coil."
"Armed," Halden said. "On your word."
On the plot, the frigate turned toward the derelict. The beacon in the derelict's hull was still in standby. The cores sat in the cargo cradle, cold and quiet. The Belt outside was the color of old iron.
"Broadcast it," Heth said.
Odera's fingers moved. The Iron Silence opened its mouth and shouted the Combine's own command frequency into the dark, on every band, unencrypted, a long bright wire stretched from the smuggler's hull to anyone in the sector with ears to hear.
The frigate heard. Heth saw the change on the plot in real time: the green smudge accelerated, the drive plasma flaring, the profile brightening as the mine class threw itself toward the source of the noise.
"Hold," Heth said.
The frigate closed. Seven thousand kilometers. Six. Five.
"Halden," Heth said. "On my mark, I want one round into its drive housing. Vessa's round. The experimental."
"Understood," Halden said.
Four thousand kilometers. The frigate's weapons were cycling up; Heth could see the change in its emissions, the faint tremor in its signature that meant a coilgun was spinning to readiness.
"Mark," Heth said.
Yenna pressed the stud. The coil sang. The round left the ventral mount at a speed that was not natural, a streak of light that was not a light, and crossed four thousand kilometers in a time Heth did not have the instruments to measure.
The round hit the frigate's drive housing. Not the hull. Not the magazine. The housing, the soft place under the engine where the plasma bled away if the magnetic bottle lost its shape. The round punched in, and the housing bloomed, and the frigate's drive plasma went wide.
The frigate did not die. A mine class was too heavy to die from a single wound. But it flinched. Heth saw the flinch on the plot: the green smudge shuddering, the drive signature fragmenting, the ship sliding sideways off its heading as the pilot fought to keep the wounded engine from spinning the hull.
"Hold," Heth said. "Do not fire again."
On the sensor station, the plot was changing. Other signatures were moving. Heth could not read them yet, but Odera could, and her face in the screen's reflected light was the face of a woman watching a door open.
"Sector command," Odera said. "They heard us. They are triangulating on the broadcast."
"Good," Heth said.
"The Combine fleet is scrambling," Odera said. "They heard themselves heard."
"Good," Heth said.
On the ventral feed, Halden was already clearing the cradle, pulling the spent coil down with the careful hands of a man who had built the thing and intended to build another. Vessa stood at his shoulder, her face unreadable, her hands at her sides. The coil was cooling. The bay smelled of ozone and burnt metal.
Pell came onto the bridge. He stood behind Heth for a moment, watching the plot, then said, quietly, "Captain. The frigate has not fired."
"No," Heth said. "It is wounded. It is trying to remember who it is."
The frigate steadied. Its drive plasma came back, ragged, uneven, but back. It began to turn, not toward the Iron Silence, but away, back toward the Belt's deeper dark, back toward whatever rendezvous the command frequency had been telling it to make.
On the plot, the other signatures were closing on that rendezvous. Sector command was moving faster than Heth had dared to hope. The Combine fleet was moving faster than Heth had dared to hope. The dark was full of trajectories, and all of them were converging on the same point.
"Captain," Odera said. "I am being hailed."
"On what band," Heth said.
"On the band you just opened," Odera said. "On an open loop. Unencrypted. By someone who knows the frequency you broadcast."
Heth looked at the plot. The signatures were still moving. The frigate was still retreating. The bay was still cooling.
"Put it through," Heth said.
The voice came through the bridge speakers, flat and dry, the way an old whiskey is flat and dry, with no warmth in it and no need of any.
"Captain Rowant," Maren Vex said. "You have just made a great many people very busy."
"I have," Heth said.
"Sector command has the fleet," Maren said. "They will move within the hour. The Combine knows we are here. They will come for us."
"I know," Heth said.
"Then you had better be somewhere else when they do," Maren said.
Heth looked at the plot. The Iron Silence sat in the dark, surrounded by a thickening pattern of trajectories. The cargo bay was cooling. The cores were quiet. The broadcast was still running, Odera's keys still moving, a long bright wire still stretched from the smuggler's hull into the listening dark.
"We will be," Heth said. "We have a shipment to deliver."
There was a long pause on the other end. Heth could hear, faintly, the sound of Maren Vex not laughing. It was the closest he had ever heard her come to it.
"Captain Rowant," she said. "I will be in touch."
The channel closed. Heth stood on the bridge of the Iron Silence, in the quiet after the broadcast, and listened to the ship cool around him. Outside, the Belt was full of movement. The Combine fleet was running. Sector command was hunting. The derelict sat in its rock, the beacon still in standby, waiting for the next smuggler to come along and decide what to do with what had been left behind.
"Helm," Heth said. "Take us out. Quietly."
The Iron Silence turned. The dust fell away. The dark came in, and the ship went into it, carrying its shipment, carrying its broadcast, carrying the quiet names of the people who had made the noise and the people who had listened.
Pell came onto the bridge one more time. He stood at his station for a long moment, watching the plot thin out behind them, then said, "Captain. What now?"
Heth did not answer for a moment. He looked at the plot. He looked at the bay feed, where Halden and Vessa were already beginning to break down the cradle for the next round. He looked at Odera, who had pulled her headset down around her neck and was sitting back in her chair with her eyes closed, listening to the echo of the broadcast in her own ears.
"Now," Heth said, "we find somewhere to sell four cores, and we try not to get killed doing it."
Pell nodded. The Iron Silence slipped into the Belt, and the dark closed over it like a hand over a candle, and the chapter of the marchward sweep ended the way all such chapters end, with a ship in the rock and a debt unpaid and a long bright wire still ringing in the ears of everyone who had heard it.
