The shuttle's landing struts bit into Phobos regolith with a sound like a hammer striking old bone, and Elias Trent's coffee slid off the tray.
He caught it before it spilled. Barely. The cup was cold anyway, the same temperature it had been since the freighter out of Ceres dumped him at the Deimos transfer station twelve hours behind schedule. Trent wrapped both hands around the ceramic anyway, because the habit of holding it kept his fingers from drumming on his thighs.
Outside, the dust settled in slow curtains across the observation port. Phobos was a wound in the sky, pocked and ancient, its surface scarred by a hundred years of human occupation. The regolith was grey-brown, fine as flour, and it coated everything, including the scarred flanks of Ashby Detachment's main hangar where floodlights threw pale columns into the black. The base clung to Stickney Crater's inner wall like a barnacle on a rusted hull, half-buried modules bristling with antennae and weapon mounts.
Trent counted three gun emplacements before he stopped counting.
The shuttle's seal broke with a hiss and recycled Phobos air rolled in: dry, metallic, faintly alkaline, tasting of old solder and something older underneath, like dust from a tomb nobody had opened in a century. He shouldered his duffel. The strap dug into his shoulder where the harness had worn the skin raw on the outbound flight. He did not adjust it.
The hangar was quieter than it should have been.
Half a dozen figures in unmarked grey coveralls worked at consoles along the far wall, none of them turning. A forklift trundled past with a crate of compressed water. Two technicians crouched over an open panel, murmuring in a dialect Trent did not recognize. Nobody looked up when he stepped off the boarding ramp.
Then a corporal in Ashby Detachment's black-and-silver subdued crossed the deck toward him. She was older than Trent by fifteen years, the lines around her mouth set deep as if the smile had been hammered out of her long ago. Her eyes flicked to his duffel, then to his throat, where the slate dog-tags Troop refused to let him wear had left a permanent tan line.
"Trent." She said the name the way a butcher says a side of beef, flat and professional.
"Corporal."
"I'm Marcano. Ines Marcano. Operations." She did not salute. "You're the cartographer."
"I was."
"Past tense." She turned and walked. He followed. The hangar floor vibrated under his boots, machinery somewhere below running its endless accounting of pressure and oxygen and the small deaths of vacuum seals. "Quarters are in Sub-level Three. Bunk assignment 7-G. You will eat at 0600, 1200, and 1800. You will not enter Hangar Bay Two without escort. You will not access the long-range comms without authorization from Commander Voss. You will not, under any circumstances, speak to the press."
"Yes, Corporal."
She stopped walking. Turned. Her eyes were the colour of dirty ice.
"I knew your brother."
Trent's hand tightened on the duffel strap. The raw spot under his shoulder throbbed once.
"So did a lot of people," he said.
"So did a lot of people," she agreed. "Most of them are dead. The rest of them remember."
She resumed walking. He followed. The corridor they entered was narrow, lined with stripped plating and exposed conduit. The lights were the colour of old butter, and they flickered in a rhythm Trent decided not to learn. Somewhere deeper in the base, a pump coughed and recovered.
Marcano did not speak again until they reached Sub-level Three.
Bunk 7-G was a coffin with a mattress. The walls were painted the same grey as every other surface Trent had seen on Phobos, the colour of waiting. A fold-down shelf held a thin pillow and a single grey blanket. Above the bunk, a small porthole showed a slice of black sky and, just at its edge, the curve of Mars, rust-red and bruised with storm.
Marcano stood in the doorway, arms folded.
"Kane arrived yesterday. He's in 7-C. Wants to see you before briefing."
"Hollis Kane."
"You know him."
"I've heard him." Trent set the duffel on the bunk. "Financed the second attempt at Meridian. Financed the third. He's why I'm here."
"He's why a lot of people are here." Marcano's voice stayed flat, but something moved behind her eyes. "He talks a lot. Listen to the words. Don't trust them."
She turned to go.
"Corporal."
She paused.
"Why do they call it Ashby Detachment."
She looked at him for three seconds longer than comfortable. Then she left.
The door stayed open a quarter inch, as if the seal could not quite decide whether to trust the air.
Trent sat on the bunk. The mattress was thin enough that he could feel the frame's metal ribs through it. He had brought nothing to unpack. The duffel held a change of clothes, a leather case with the half-finished charts of the Meridian's upper passages, and a photograph in a frame so old the cardboard had begun to soften at the edges.
He did not take the photograph out.
He could hear the base breathing around him. Pumps cycling. The faint tick of thermal expansion in the bulkheads. Someone in the next corridor laughing once, briefly, the way people laugh when they have forgotten how. In 7-C, two doors down, Hollis Kane was either sleeping or scheming, and Trent did not know which would be worse.
He stood. He had been on Phobos for eleven minutes and the silence was already heavier than the gravity.
Trent went to find a coffee that was not cold.
The galley was four decks up, reached by a ladder so steep his knuckles brushed the rung above. The room beyond was empty except for an automated dispenser built into the wall and a single figure at the far table, hunched over a cup. The figure did not look up when Trent entered, but he registered the duffel, the boots, the way Trent moved around the room as if memorizing the exits.
Veterans always knew.
Trent punched his order into the dispenser. It ground-glowered through its options and produced something the colour of engine grease. He carried it to the table opposite the figure and sat. The man across the table was broad, bald, with a scar that started under his left ear and disappeared beneath his collar. His hands were the hands of a man who had learned to be gentle with small things and had unlearned it.
"Trent," the man said.
"Yes."
"You're him, then." The man's eyes moved over Trent's face the way a surveyor reads a map. "You have his jaw."
Trent tasted bile. He swallowed it with the coffee. The coffee was worse than the cold one.
"His jaw," Trent repeated.
"Ashby. Tomas Ashby. Your uncle." The man wrapped both hands around his cup, the way Trent had wrapped his on the shuttle. The gesture was so familiar Trent's throat closed. "He broke a sergeant's nose in a bar in Luna City once, for calling him a tourist. Same jaw. Same way of sitting like he was waiting to be told to leave."
"My uncle has been dead eleven years."
"Dead is a strong word for it."
Trent set his cup down. The table was scarred with cigarette burns and the ghost of a stencil that might once have read PROPERTY OF. He did not ask what the man meant. He knew the stories. Everyone in the inner system knew the stories.
Tomas Ashby had been the greatest cartographer of his age, a soft-spoken West Indian academic who had spent forty years drawing maps that no one wanted. Then, at sixty-three, he had walked onto the surface of the planet nobody had ever returned from, and he had walked into the Meridian, and he had not walked out.
The official report said death. The unofficial reports said nothing, because nobody who went in came out to give them.
His body had never been recovered.
"Dead is a strong word," Trent said. "It is the word the Department of Cartography uses."
"The Department of Cartography can go hang." The man drank. "You here for the fourth attempt."
"Third."
"Third." The man considered this. "Kane's money. Ashby's name. Trent's feet. Same as the first. Same as the second."
"You were on the second."
"I was on the second." The man set his cup down with the careful precision of someone who had learned the hard way that sudden movements attract attention. "There are six of us left. We do not talk about it. Voss has made that policy."
"Voss."
"Commander Voss. Our commanding officer. She does not love you either." The man stood. He was shorter than Trent had expected, and heavier through the chest, the way a man gets when gravity has been patient with him. "You remind her of him. That is not a compliment."
He left. The galley was empty. The dispenser hummed its small mechanical hymn, indifferent.
Trent finished the cup. It tasted the way he felt.
In his bunk, he lay on his back and watched Mars through the porthole. The planet turned, slow as a fever, and he thought about his uncle's hands. He had been seven when Tomas Ashby had first spread a map across the kitchen table in their house outside New Havana, and the hands had been steady as carved wood, the fingertips ink-stained, the nails trimmed short because long nails tore paper. He remembered the smell of the ink, sharp and vegetal, like crushed grass.
He remembered his brother watching over his shoulder, ten years old, silent with the particular silence of a child who has decided to become someone.
Where are you, he thought. The same thought he had thought every day for eleven years.
The pump coughed. The answer of machines.
He slept.
The summons came at 0400, a knock so perfunctory it might have been the wind, except there was no wind on Phobos. Trent was already dressed. He had not managed to fall asleep, and he had been sitting on the edge of his bunk with his boots on for forty minutes, watching the slice of Mars darken as Phobos swung into Mars' shadow.
The messenger was a private whose name Trent did not catch, young, with a face that had not yet learned what it was for. He led Trent up two decks, down a corridor Trent had not seen, and into a briefing room whose door bore a placard that read COMMAND.
Inside, three people waited.
The first was Commander Voss, a tall woman in a pressed uniform with the insignia of a colonel borrowed from a war no one remembered. She sat at the head of the table with her hands folded, and she did not look up when Trent entered. Her hair was iron-grey and cropped close. The scarves of rank on her collar had been polished so often the fabric had begun to fray at the edges.
The second was Hollis Kane, and Trent understood immediately what Marcano had meant.
Kane was a small man with a small voice and a smile that took up half his face, a salesman smile that had been sanded down to a comfortable smoothness over decades of use. He wore civilian clothes on a military base, a wool coat the colour of good soil, and he sat in his chair as if it had been built for him. When Trent entered, Kane rose halfway and extended his hand as if they were meeting at a reception.
"Elias." The Dublin was thick enough to chew. "At last. I have been hearing your name for years."
"You have been reading my charts."
"I have been paying for your charts." Kane's smile did not waver. "And for the privilege of pretending you wrote them for the love of the work. Sit. There is coffee. It is not good, but it is hot."
The third person in the room was a woman Trent did not recognize. She sat at the far end of the table, apart from the others, with a tablet open before her and a stylus turning between her fingers. She had dark hair pulled back tight, and a stillness to her that reminded Trent of a tide pool: surface calm, depth unknown.
"This is Solberg," Voss said, finally. "Our science officer."
Yara Solberg looked up. Nodded once. Looked down.
"She does not talk much," Kane said, cheerfully. "I am told this is an asset."
Trent sat. The coffee was, in fact, hot. He did not drink it.
Voss opened a folder. The folder contained a single map, hand-drawn, on paper so old the corners had begun to soften. Trent recognized the hand before he recognized the lines.
It was his uncle's.
"This," Voss said, "is the most complete map of the Meridian in existence. It is also the only one. It has been in the Department of Cartography's archive for eleven years. Three weeks ago, it was declassified under a sealed order I am not at liberty to discuss. It is now in our possession. It is the reason you are here, Trent. You are here because your uncle drew this, and you are the only cartographer in your family who has agreed to come."
Kane set down his coffee.
"In fairness, Commander, the boy was the only cartographer in his family with a price."
Trent's hand tightened on the cup.
"You did not pay me," he said. "You paid my brother's debts."
"Your brother," Voss said, "is not here."
"My brother," Trent said, "is on the Meridian. If he is alive, he is on the Meridian. That is what the map says. That is what every chart I have drawn for the last eleven years says. That is why I came."
Kane raised an eyebrow. Solberg did not look up.
Voss closed the folder.
"Then we understand each other," she said. "Briefing is at 0800. You will be introduced to the rest of the unit. They have opinions about your family. I expect you to let them keep them."
She stood. Kane stood. Solberg remained seated, stylus still turning.
"Elias," Kane said, as Trent reached the door. "One more. Don't."
Trent turned.
"Don't make me regret paying for the coffee."
Trent walked back to his bunk in the dark. Mars had swung clear of the bulkhead, and the porthole was full of stars, the kind of stars you only saw out here, where the atmosphere was a memory. Somewhere in the base, a man was laughing again, and the laugh was cut short, and the silence that followed was the silence Trent had been hearing for eleven years.
In 7-C, Kane's light was still on.
Trent lay down. He did not close his eyes.
At 0600, the mess hall descended.
Petra Almasi had learned to count the ways a person could arrive at a briefing, and Kane was the rarest of them: early, unhurried, already seated when the room was half-empty, a second cup of coffee balanced on his knee like a man auditioning for a portrait of ease. He was speaking to Trent. Petra had not meant to hear. The mess hall funneled sound into corners the way a throat funnels breath, and the corner she had chosen for her eggs was three meters from the corner they had chosen for their grievance.
She kept her eyes on her tray.
"--the hell you mean, you are not eating."
"I am not hungry."
"You are always not hungry when you are in a mood. Eat."
"Hollis."
"Eat, Elias."
The fork clinked against the plate, which meant Trent had picked it up, which meant Kane had won again. Petra did not look up. She had been told, by a man with no neck and three rows of ribbons, that the first rule of a new posting was to know when a conversation was not about you. She had been told a great many things by a great many men with no necks. The advice had not yet failed her.
Kane's voice pitched lower. Petra stopped chewing.
"After," he said. "Come to the pool. I want to show you something."
"Hollis, I have to be on the floor at 0800."
"You have forty minutes. The pool is on the way."
"It is not on the way."
"Everything is on the way if you take the service corridor. Come."
Trent did not answer. Kane did not wait for an answer. Petra heard the scrape of his chair, the click of his cup set down, the unhurried tread of boots that had walked every deck of this station and would walk them again. She counted his footfalls out of habit. Twelve to the door. The door sighed shut behind him.
She let out the breath she had been holding and looked across the table at Solberg, who was drawing a small face on her tablet with one finger.
"You heard that," Petra said.
"I heard everything," Solberg said, without looking up. "I always hear everything. It is a problem."
"What do you think he wants to show him?"
"Something old," Solberg said. "Kane only gets that voice when something old is involved. The voice gets rrrr. Listen."
Petra listened. Kane had gone. The mess hall was filling with the dull percussion of trays and the higher sound of the coffee urn cycling through its second boil. Somewhere near the porthole a man was laughing again, and the laugh was cut short, and the silence that followed was the silence she had been hearing for three days.
Solberg turned the tablet toward her. The face she had drawn was a skull.
"Do not," Petra said.
"It is not for him," Solberg said. "It is for me. I draw what I feel."
"And you feel like a skull."
"I feel like the morning before the morning we do not come back from. Is that a skull?"
"Solberg."
"It is a joke. Bad joke. Eat your eggs."
Petra ate her eggs.
At 0714, she went to the motor pool.
The motor pool occupied Bay Four of the secondary deck, a cavern of low yellow light and cold iron that smelled, as it always did, of hydraulic fluid and the ghost of something older: rocket propellant, perhaps, or the resin of the cedar crates the first deployment had shipped in, fifteen years gone. The shuttles sat on their cradles like roosting birds, bellies split for maintenance, pylons dark. The floor was black with old grease and the tread marks of boots that had come and gone.
Trent was already there.
He was standing at the far end, by the number three shuttle, where a canvas tarp had been pulled back to expose a section of hull that bore a patch of new welding. Kane was beside him. Kane had a mug in one hand and something small and bright in the other. Petra hung back by the door, under the nozzle of a foam dispenser, and pretended to check the seal on her cuff.
Kane did not look around.
"Fifteen years," he was saying, in the low rrr of his Dublin. "Fifteen years, give or take the leap correction. I keep it in the locker because I am sentimental, which is a thing people do not believe about me, and which is true, and which I will deny if asked."
"What is it," Trent said.
"A picture."
"Of what."
"Of us."
Petra heard the catch in Trent's breath. It was a small sound, the sound of a man who has been bracing against something and finds it has already arrived.
"Show me," Trent said.
Kane thumbed the holopicture awake.
Petra did not move. The holopicture threw its light across the side of the number three shuttle and painted, in pale blue, a group of seven people standing on what looked like the observation deck of a smaller vessel. They were dressed in the loose jackets of an early expedition, and the jackets were too new, and the smiles were too new, and the stars behind them were the same stars that poured through the porthole of Trent's bunk every night.
Kane was in the picture. Younger by fifteen years and a stone, but recognizably himself, his grin wide, his arm around the shoulders of a woman whose face was turned half away.
"That is Ines," Kane said. "Before she was a commander. Before any of us were what we became. Look at her. Look at the eyes on her."
Trent did not look at Ines. He was looking at the man on the far left.
"Who is that," Trent said.
"That," Kane said, "is your uncle."
Tomas Ashby stood at the edge of the picture the way he had apparently stood at the edge of every picture of his life: half in, half out, his shoulders turned toward the frame as if listening for a sound from the corridor. He was older than Trent by thirty years and shorter by a hand, and the look on his face was the look Petra had learned to recognize from three days of observation: the look of a man who knew exactly what he was about to lose and had decided to lose it cleanly.
"He drew that," Trent said.
"He drew it on the boat out. He drew it on the boat back. He drew it on every chart you have ever held. That is the hand."
"Hollis."
"That is the hand, Elias."
"Hollis, I know the hand."
"Then look at the hand. Look at the face. Look at the man you have been chasing for eleven years. He is right there. He is in the picture."
Trent did not speak. The holopicture hummed. Kane swirled the coffee in his mug and watched Trent the way a card player watches a man decide whether to call.
"He is alive," Kane said. "You know he is alive. That is why you came. That is the only reason you came. You did not come for the money, and you did not come for the flag, and you did not come because I asked politely."
Trent did not answer.
"I am showing you the picture," Kane said, "because I want you to remember, when we get to the briefing, what it looked like before. So that when they tell you it has changed, and they will tell you it has changed, you do not let them change you."
"Hollis," Trent said, "stop."
"I will stop," Kane said. "I have stopped. Look at the picture."
Trent looked at the picture.
After a moment, he said, "Who is the woman."
Kane glanced up. "What woman."
"Behind Ines. Half-hidden. I have seen her face before."
Kane squinted. The holopicture shifted. The half-hidden woman resolved into a woman of about fifty, dark hair cropped close, eyes on the camera, mouth unsmiling.
"That," Kane said slowly, "is a woman I do not recognize."
"She has been on the news," Trent said. "She is the Sovereignty liaison. She was at the commission hearings last year. I forget her name."
"Petra," Kane said. "Petra Almasi."
The sound of her own name, spoken three meters away, in the voice of a man who had not noticed her, did something to Petra's spine. She stood very still. The foam dispenser clicked softly behind her. Neither man turned.
"She is not in this picture," Kane said. "This picture is fifteen years old. She would have been a child."
"Then she is someone who looks like her."
"Or," Kane said, and stopped. He looked at the picture. He looked at the door. He looked at the picture again.
"Or," Trent said, "she is the one they have sent to finish it."
"Hush," Kane said. "Not here."
He thumbed the picture off. The blue light died. The motor pool returned to its yellow. Trent looked older in the yellow light than he had in the blue, and Kane looked older than both of them, and the shuttles sat on their cradles like roosting birds that had been told something they did not want to know.
At 0752, they walked to the briefing.
The briefing room was on the command deck, a long, low chamber with a curved screen along the forward bulkhead and a smell of recycled air and the particular staleness of a room where many decisions had been made and few had been kind. The chairs were molded plastic. The carpet was industrial. The flag of the Sovereignty hung over the screen, and beside it the flag of the Expeditionary Corps, and beside that a third flag Petra did not recognize, which meant it was new.
Voss was already at the podium. She wore the same uniform as the night before, but her hair had been re-pinned, and the pins were silver, which on Voss meant either ceremony or trouble.
Solberg was in the third row, tablet open. Petra took the seat beside her. Kane and Trent filed in behind, and the room filled with the sound of boots and the smell of fresh coffee and the faint ozone of the projector warming up.
At 0800 exactly, the screen lit.
Voss did not greet them.
"Ashby Detachment," she said. "What I am about to tell you does not leave this room. If it leaves this room, I will find out. If I find out, the finding out will be the worst part of your day. Sit up."
They sat up.
"Eleven days ago," Voss said, "a long-range picket in Sector 12 detected an anomalous emissions profile consistent with the telemetry recovered from the Meridian catastrophe in the year 4."
The room did not breathe.
"I will repeat myself once," Voss said. "Anomalous emissions. Consistent. Sector 12. Eleven days ago. The profile has been confirmed by three independent signals shops, including one at Sovereignty Intelligence. We are not chasing a ghost. We are chasing a signal."
Petra's pen stopped on the page. Solberg's stylus stopped on the tablet. Across the row, Kane's mug stopped halfway to his mouth.
"The species colloquially known as the Hollow," Voss said, "have reappeared."
She let the sentence stand. She did not elaborate. She did not need to. The word Hollow had been carved into the public memory of the Meridian like a name on a cenotaph, and the name meant nothing and everything and the silence that followed it was the silence of eleven thousand people who had not come back.
Voss waited.
"At 0400 yesterday," she said, "the Sovereignty Council authorized what is being termed Phase Two operations in the Meridian sector. Ashby Detachment is being reactivated for this purpose. We will deploy under joint oversight with Sovereignty Intelligence. The detachment commander remains myself. The intelligence liaison is being assigned this morning. Her name is Petra Almasi. She is in this room. She is not to be touched."
The room did not turn. They had been warned about turning. But Petra felt the weight of twenty gazes settle on her like a hand on the back of her neck, and she felt her own face do nothing at all, which was the only face she had practiced for eleven years.
Solberg, beside her, had gone very still. The stylus was no longer moving. The skull she had drawn at breakfast was still on the tablet, half-finished, and Petra could see it now over the rim of her own notebook.
Voss moved on.
"The mission profile," Voss said, "is reconnaissance in force. We enter the Meridian through the route charted by the original expedition. We proceed to the last known coordinates of the signal source. We establish a perimeter. We do not engage. We observe, we record, we withdraw. Repeat. We do not engage."
The screen changed. A star chart unspooled across it, blue lines on black, and at the end of the longest line a small red dot pulsed like a heart.
"This," Voss said, "is where we are going."
Petra looked at the red dot. She looked at the chart. The chart was in the hand she had seen on the holopicture twenty minutes ago, the hand that had drawn the only complete map of the Meridian, the hand of the man Trent had been chasing for eleven years.
She did not know, yet, that the chart had been drawn by Tomas Ashby.
She would know by nightfall.
Kane's mug came down on the chair arm with a small, precise sound, like a gavel. He did not look at her. He looked at the screen. Trent, beside him, did not look at the screen. He was looking at his own hands, open on his knees, as if checking whether they were still the hands he had woken up with.
Voss clicked to the timetable.
"Movement order is in twelve hours. All personnel report to the motor pool at 2000. All personnel are dismissed."
The room began to stand. Petra did not stand. She sat with her pen in her hand and her notebook open and the red dot still pulsing on the screen, and she thought, with the calm that had carried her through eleven years of rooms like this one, that the chart on the wall was the chart her mother had refused to sign, and that in twelve hours she would be on her way to the place where the signature had been owed.
Solberg reached across and closed the tablet over the skull.
"Do not," Petra said.
"I am hiding it," Solberg said. "For later."
She tucked the tablet under her arm and stood, and the lights in the briefing room began, one by one, to come up.
