The elevator groaned, its cables singing a thin metallic note that vibrated through the soles of Mara Vance's boots. Forty-three. The numbers above the door flickered once, twice, then held steady in pale green. She stepped forward as the doors parted, and the smell hit her first: wet char, copper, and something older underneath, the ghost of paper and ink long since burned.
She pulled a white cotton mask from her coat pocket and pressed it over her nose and mouth. The fabric was thin, almost decorative, but it caught the worst of the fine particulate that drifted through the corridor like a suggestion of snow in July.
The hallway stretched ahead of her, lit by emergency strips along the floor that cast everything in a dim, underwater glow. One of the overhead panels had survived intact, and it threw a pale rectangle of yellow-white light across the carpet where the ash lay thickest. The carpet itself had been blue, once. Now it was a mottled gray-black, the pile matted in waves from whatever water or suppressant had been used to kill the blaze.
Mara reached into her satchel and pulled out a slim tablet, its screen already scarred with old cracks. She thumbed it awake and held it against her forearm while she walked, letting the device scan as she moved. The building's administrative skeleton was already loaded: floor forty-three, residential and administrative hybrid, six units, two stairwells, one freight elevator, one bank of standard-issue comm stations.
One of those comm stations had been the source of the call.
The unit at the end of the hall, 43-C, according to the registry printout, was supposed to have been unoccupied for eleven months. Its tenant, a man named Edric Tolle, had been listed as deceased following the fire that swept the thirty-ninth through forty-fifth floors of the Helix Complex fourteen months ago. The death certificate had been signed by a Dr. Yael Quinn, filed through the Civic Registry's verification queue, and stamped with the Bureau's seal of approval. Clean. Routine. Case closed.
Except that Edric Tolle's body had never been recovered from the wreckage. And three days ago, someone had made a call from 43-C.
Mara stopped outside the door. The standard-issue lock had been overridden; the manual release had been triggered from inside, leaving the door ajar by a finger's width. She could see the edge of the seal, blackened but intact, and the faintest flicker of light from beyond.
She pushed the door open with the back of her wrist and stepped inside.
The unit was small, efficient, built for a single occupant or perhaps a couple without children. A narrow galley kitchen lined the left wall, its surfaces buried under a fine layer of soot. A folding table and two chairs sat beneath a window that had cracked under heat stress, the glass now a spiderweb of fractures held together by nothing but adhesive tape applied in a hurry. Beyond the table, a sleeping alcove separated by a curtain of brushed steel links. A sleeping platform, stripped of linens. A standing lamp, its bulb dark.
The light source was the comm station, mounted on the wall beside the entry. Its indicator glowed a steady amber, cycling through its handshake protocol with the patience of something that had been waiting a long time.
Mara approached it, keeping her mask pressed tight, and studied the unit without touching it. The model was older than what the current building code required. A pre-refurbishment Civic Standard, manufactured sometime in the last decade but retired from active service at least five years ago. The casing showed scratches around the input ports, wear marks that suggested frequent use. A thin curl of paper tape had been stuck beneath the screen at some point, then removed, leaving a faint adhesive residue.
She crouched, bringing her eyes level with the device's lower housing. There, half-hidden in the seam where the casing met the wall mount: a smudge of something darker than soot. Not paint. Not rust. She leaned closer, careful not to breathe too deeply. The smell beneath the mask turned faintly sweet and wrong, the kind of sweetness that came from accelerants or, worse, from the early stages of organic breakdown.
Mara straightened and reached into her satchel again, this time producing a small evidence kit. She unsealed a swab packet, broke it open, and ran the sterile tip along the seam where the dark residue clung. The swab came away stained a deep burgundy that was almost black in the low light. She sealed it in a labeled tube and slipped it back into her kit.
"Talk to me," she murmured, half to the unit and half to herself. "What did you see?"
The comm station offered nothing. Its amber light blinked, steady as a heartbeat.
She turned her attention to the rest of the room. The folding table was bare except for a single object: a ceramic mug, half full of liquid that had long since evaporated, leaving a ring of mineral residue on the surface. The chair nearest the mug had been pulled back at an angle, suggesting someone had been sitting there. The other chair was tucked neatly under the table, unused.
Mara crossed to the sleeping alcove and parted the steel curtain with one finger. The platform beneath was bare. The walls were bare. A single drawer in the low cabinet beside the platform was pulled open an inch, empty.
She crouched again, this time to examine the floor near the curtain. The ash here was disturbed. Someone had knelt. She could trace the pattern of weight displacement in the way the fine gray powder had been pressed aside, revealing the darker carpet beneath. A second set of marks, smaller, pointed toward the wall opposite the comm station, as though whoever had knelt there had turned to face something else in the room.
Mara rose and followed the direction of those marks.
The wall was paneled in a synthetic wood veneer that had buckled and warped from the heat. One of the panels, near the floor, had been pried loose at its lower edge, the adhesive seal broken in a clean horizontal line. She knelt and pulled the panel free with both hands, the broken seal releasing with a sound like tearing cloth.
Behind the panel, a shallow recess had been cut into the wall's framing. The space was empty except for a folded slip of paper, cream-colored, untouched by the soot that coated every other surface.
Mara lifted the slip carefully, holding it by one corner. The paper was heavy, the kind used for official correspondence. A single line had been typed across its center, the letters precise and uniform:
HELIX FLOOR 43 DOES NOT EXIST.
She stared at the words for a long moment, the mask rising and falling with her breath. Then she folded the paper once, slipped it into a clear evidence sleeve, and tucked it into her satchel.
A sound reached her from the corridor outside: the faint whir of the freight elevator descending past forty-three and continuing downward.
She rose, smoothed her coat, and stepped back into the hallway. The elevator's indicator was already past forty by the time she reached the lobby doors, descending fast. Whoever had been up here with her, or before her, was leaving the building.
Mara pressed two fingers to the comm unit at her ear, activating the building's internal channel.
"Registry field unit, forty-three clear," she said, her voice low and even. "I need the freight log for the last six hours, and I need a maintenance roster for this floor going back eighteen months."
A pause. Then a voice, clipped and bored, responded from the other end.
"Logged. Anything else, Vance?"
"Pull the original incident report on the Helix fire. I want the full chain of custody on every artifact recovered from forty-three."
"Long list. You want the summary or the raw?"
"Raw." She paused. "And Hsu. If Dorian's name shows up anywhere in the recovered documentation, flag it."
The line went silent for three full seconds.
"You sure about that?"
"I'm sure." Mara turned back toward 43-C, her eyes on the amber light of the comm station. "And send someone to cover the freight bay. I want eyes on whoever just left this floor."
"Copy. Logistics says ten minutes."
"Make it five."
She severed the connection and stood alone in the dim corridor, the ash settling around her boots in slow gray spirals. Somewhere above her, a pipe ticked with trapped heat. Somewhere below, the elevator groaned on its way to the lobby.
Mara Vance pulled her tablet back up and began photographing the scene, working methodically from the doorway inward, her mind already sorting the details into questions. The falsified certificate. The missing body. The call from a dead man's unit. The paper tucked behind a false panel. The smudge on the comm casing.
And the message itself. Helix floor 43 does not exist.
She had seen the floor plans for the Helix Complex when she first took the assignment. Forty-three existed in every blueprint, every schematic, every fire safety certification filed with the city. It was there in the original architectural drawings from forty years ago, when the Helix had been the crown jewel of the Civic expansion.
Forty-three existed.
And yet someone had gone to the trouble of hiding a typed note in a dead man's wall, in a unit that should have been empty, in a building that should have been cleaned and cleared after the fire.
Mara finished her documentation and sealed the room behind her with a strip of tamper-evident tape across the door frame. She would need a full forensic team to comb the unit properly, but first she needed answers to questions that no lab could provide.
She rode the standard elevator down to the lobby, stepping out into the restored marble and brass of the Helix's main entrance. The concierge station was unmanned, the desk covered in a fine layer of dust that suggested the building's lower floors had been cleared and locked since the fire. She crossed to the building's administrative kiosk and pressed her palm against the biometric panel.
"Field authorization, Mara Vance, Ministry of Historical Records. I need access to the original Helix building permits and the post-incident modification filings."
The kiosk hummed, its screen flickering to life.
"Access granted. Partial. Certain filings are sealed under Civic Preservation Order 714. Do you wish to request an unbreakable review?"
"I do."
"Request logged. Estimated response time: seventy-two hours."
Mara's jaw tightened. Seventy-two hours was enough time for whoever had arranged this to vanish entirely.
"Work faster," she said, knowing the machine would not understand and not caring.
She turned and walked out into the morning light, the Helix's brass doors closing behind her with a hiss of pneumatic seals. The street beyond was quiet, the early hour keeping the foot traffic sparse. She crossed to a small café on the corner, its windows steamed from the espresso machine inside, and ordered a black coffee she did not intend to drink.
She found a table near the back, away from the door, and spread her notes across the surface. The evidence sleeve with the typed slip sat at the center, the words facing up.
HELIX FLOOR 43 DOES NOT EXIST.
She picked up her comm unit and dialed a number she had not called in nearly two years.
It rang four times before a gravelly voice answered.
"Vance." The name came out flat, neither welcome nor rejection. "You found something."
"I found a message," Mara said. "And I need to know why a dead man's comm station made a call three days ago."
Silence on the other end. Then a long, slow exhale.
"Come down to the bindery," the voice said. "And bring that message. Don't tell anyone else you're coming."
The line went dead.
Mara pocketed the comm, left a handful of coins on the table, and stepped back into the street. The morning was gray and cold, the kind of cold that settled into the bones. Somewhere across the city, the Helix Complex stood empty and waiting, forty-three floors of ash and silence and a single amber light that would not stop blinking.
The lower district smelled of ink and binding glue, the sharp chemical tang mixing with the wet stone smell of the streets after rain. Mara found the bindery tucked between a cobbler's shop and a tea merchant whose windows were fogged from constant boiling. The sign above the door read FENN AND DAUGHTER in faded gilt, though Mara knew the daughter was long gone, moved to the northern provinces after a falling-out no one in the district would discuss.
The door protested when she pushed it open, hinges shrieking on dry metal. Inside, the shop was narrow and deep, shelves climbing to the ceiling on both walls, each one bowed under the weight of bound volumes, loose folios, and the occasional spine-less folder that someone had forgotten to file. Light came from a single window near the back and from the bare bulb hanging over the workbench, where a man in his late seventies sat hunched over a sheet of leather, stitching a spine with a curved needle.
He did not look up when she entered.
"Lock the door," he said.
She did. The bolt was heavy, old iron, and it slid home with a satisfying clunk. Somewhere above them, pipes groaned, and a radiator in the corner ticked and pinged as it warmed.
Mara crossed the shop, stepping over a crate of archival tape that had been left in the middle of the floor, and set the evidence sleeve on the workbench beside his leather. The typed slip faced up. HELIX FLOOR 43 DOES NOT EXIST.
Fenn set down his needle. He studied the words for a long time, his gnarled fingers resting on either side of the slip as if it were a sleeping animal that might wake.
"Where did you get this?" he asked. His voice was low, rough, a voice that had spent too many years breathing smoke.
"A comm station on the forty-third floor of the Helix Complex," Mara said. "A station that belonged to a man named Cassian Vord, who died in the registry fire twelve years ago."
Fenn's eyes flicked to hers, then back to the slip.
"You went to the Helix," he said. It was not a question.
"I had to see the floor. The archive sent me a denial, but the floor is listed in the original construction permits. Someone built it. Someone used it."
"Someone sealed it," Fenn corrected. "There's a difference."
Mara waited. The radiator ticked. Somewhere outside, a cart rattled over cobblestones, the wheels uneven, the rhythm irregular.
"Sit down," Fenn said, gesturing to a stool near the window. "This is going to take a while."
She sat. Fenn lifted the slip carefully, holding it by the edges as if it might disintegrate, and carried it to a desk lamp that he switched on. The bulb was stronger than the one over the bench, and the words on the slip seemed to darken under it, the ink absorbing the light rather than reflecting it.
"I investigated the fire at the Hall of Registry," he said, his back still to her. "I was the fire marshal on the scene. I pulled bodies out. I signed the report that said the blaze was electrical, origin in the basement stacks, spread through the document storage, total loss of the eastern wing."
He set the slip down and turned to face her.
"The report was a lie."
Mara felt the words settle into the shop like a change in pressure.
"The fire started on the forty-third floor," Fenn said. "Of the Helix Complex. Not the registry. The Helix. The registry was hit because the ventilation shafts connect the two buildings, and whoever set the blaze wanted to bury the origin."
"Why?" Mara asked.
"Because the forty-third floor was being used as an off-books archive. Documents that couldn't be in the official record. Census corrections. Property transfers that reversed earlier transfers. A few hundred death certificates that were filed but never delivered to the families." He paused, his jaw working. "And a registry of every agent the Ministry of Historical Records had ever embedded in another department."
Mara's mouth went dry. "Embedded agents."
"The Ministry has been placing people in other bureaus for decades," Fenn said. "Archivists who were really spies. Quiet people who cataloged and copied and reported back. The program was called the Ledger. The floor was the Ledger's vault."
"And someone burned it," Mara said.
"Someone burned the evidence. But not before a sympathetic clerk in the ventilation office managed to seal the shaft before the fire reached the registry proper. That's why the registry lost records but not all of them. The clerk saved what he could. He died in the fire doing it."
Fenn crossed to the window and looked out at the street. The tea merchant across the way was sweeping his stoop, the bristles scraping against the stone.
"The clerk's name was Tomas Elric. He was a friend of mine."
Mara looked down at her hands. The calluses on her fingers from years of handling old documents seemed suddenly relevant.
"What does this have to do with the message I found?" she asked.
"I don't know yet," Fenn said. "But the phrase on that slip is a warning. A phrase the Ledger used when an operative had been compromised and needed to disappear. I heard it once, in a debriefing room, from a man who was dying of smoke inhalation. He said it to me before he stopped breathing."
"What did it mean?"
"It meant that the person the floor belonged to was gone, and anyone who went looking for them would be next."
The bulb over the workbench flickered, then steadied. The radiator gave a metallic clang as a bubble moved through the pipe. Mara became aware of the smell of the shop more acutely: the glue, the leather, the dust, and beneath it all, the faint chemical trace of the preservative Fenn used on the spines of the books he restored.
"If the floor was sealed," Mara said slowly, "and the people on it were killed or scattered, who sent that message to my terminal?"
Fenn turned from the window.
"That's the question, isn't it?"
He walked back to the workbench and picked up the slip again, this time tilting it toward the lamp. He studied the paper, not the words. The grain. The weight. The way it held the light.
"This is not original stock," he said. "It's a replica. A very good replica. Someone made this paper recently, using a recipe that hasn't been in use since the war. The watermark is wrong, but only by a hair. Whoever did this knew what they were doing."
He set the slip down and looked at her.
"You need to be careful," he said. "If the Ledger is still active, and someone is sending warnings from a dead floor, then there are people who will notice you've started asking questions. People with resources. People with patience."
"I know," Mara said.
Fenn held her gaze for a moment, then nodded. He crossed to a cabinet behind the workbench, opened a drawer, and took out a small key on a leather cord.
"There's a room in the back," he said. "Private collection. Things I've been holding for a long time, waiting for someone to come asking the right questions."
He handed her the key.
"Inside, on the second shelf, there's a blue folder. Don't open it here. Take it somewhere safe, somewhere with no windows and no comm reception. Read it. Then decide what you want to do."
Mara took the key. It was warm from the drawer, and the leather cord was soft from years of handling.
"Why me?" she asked. "You could have taken this to the Bureau. To the press. To anyone."
Fenn was quiet for a moment. He picked up his needle and turned back to the leather, the gesture deliberate, a dismissal that was also an answer.
"Because you came alone," he said. "And because you didn't bring the Bureau with you when you walked through that door."
Mara stood. The stool scraped against the floorboards, a sound like a sigh.
"Thank you," she said.
"Don't thank me yet," Fenn said, his needle moving through the leather with a practiced rhythm. "The folder is heavy. And it doesn't get lighter the more you know."
She crossed to the back of the shop, past the crate of tape, past a rack of presses and clamps, to a door that was painted the same color as the wall and easy to miss if you weren't looking for it. The key fit the lock without resistance. She turned it and stepped through.
The room beyond was small and dry, the air still and cool, the smell of preservation fluid stronger here. Shelves lined three walls, each one labeled in Fenn's cramped hand. She found the blue folder on the second shelf, where he had said it would be, and took it down.
It was thin. Lighter than she had expected. The cover was unmarked except for a date in the corner: twelve years ago, the year of the fire.
She tucked it under her arm and went back out through the shop. Fenn did not look up from his stitching as she passed. At the door, she stopped.
"The clerk who sealed the shaft," she said. "Tomas Elric. Did he have family?"
"A daughter," Fenn said. "She was seven when he died. The Ministry placed her with a family in the outer provinces. Closed adoption. New name. The kind of arrangement that makes a person disappear."
Mara felt the floor tilt slightly, the way it did when a tall building caught a gust.
"Where?" she asked, though she already knew.
Fenn's needle paused. For the first time since she had entered the shop, he turned and looked at her fully. His eyes were red-rimmed, the lids heavy, the gaze steady and unforgiving.
"The kind of arrangement," he said, "that doesn't leave a trail."
Mara nodded. She unlocked the door, stepped out into the street, and pulled the door shut behind her. The lock engaged with a click. She stood for a moment on the cobblestones, the blue folder under her arm, the key still warm in her hand.
Across the way, the tea merchant was wringing out his broom into a bucket, the water steaming faintly in the cold air. A woman passed on the opposite sidewalk, her coat pulled high, her breath a white plume. Somewhere a church bell rang the half hour, the sound flat and unhurried.
Mara turned and began walking toward the transit station three blocks east. She did not look back. She did not open the folder. She held it against her side and matched her pace to the rhythm of the city, her thoughts loud in the quiet of her own skull.
She had grown up in the outer provinces, an orphan of a registry fire, raised by a family that had never told her where she came from. She had spent her career in the archives, handling other people's histories, preserving other people's pasts. She had been good at it. She had been careful.
Now she carried a folder that might explain why she had been placed where she was, why she had been given the name she carried, why she had been drawn to the work she did. The questions multiplied with every step, and she forced herself not to open the folder on the street, not to risk the wind or a passerby's glance, not to let the answer escape before she was ready to receive it.
The transit station entrance loomed ahead, a concrete arch set into the pavement, the stairs descending into the blue-white light of the underground. She paused at the top, the folder under her arm, the key in her pocket, the city spreading around her in all directions like a held breath.
She went down.
The transit tunnel smelled of damp concrete and ozone, the air cool against Mara's face as she descended. Her footsteps echoed in the stairwell, a steady rhythm that slowed when she reached the platform and fell into the muted shuffle of the morning crowd. She kept the folder flat against her ribs, her elbow pinned, and stood near a pillar where the surveillance cameras had a blind spot. Old habit. The kind of habit that kept people alive in a city where everyone was accounted for and the unaccounted were sought.
The train arrived with a hiss of pneumatic doors and a wash of recycled air that carried the faint, chemical sweetness of the third rail. Mara stepped inside, found a seat by the rear door, and let the folder rest on her lap beneath her coat. The other passengers kept to themselves, faces lowered to tablets and printed papers, the soft tap of fingers on glass the only sound above the train's rhythmic sway. She watched the stations tick past, the names glowing amber behind scratched plexiglass: Civic Center, Memorial Park, Arches and Foundations, Seventeenth Sublevel.
Seventeenth Sublevel. She exited with a handful of civil servants and archivists, most of them clutching coffee in thermoses that steamed faintly in the cool underground air. The lighting here was the pale institutional white she had known for years, the floors polished to a dull shine that reflected her shoes as she walked. She climbed the stairs to street level, crossed the plaza where the fountain ran only on holidays, and turned onto the narrow service road that led to the Ministry's east wing.
Her badge worked the security gate without incident. The guard, a thin young man with a shaved head, glanced at her face, then her badge, then her face again. "Long walk, Ms. Vance?"
"Something like that," she said, and kept moving.
The archive floor was quiet at this hour, the desks spaced wide apart under a ceiling of acoustic tile and recessed lighting that gave everything the same bleached, uniform look. Mara's cubicle sat in the third row, near the window that looked out on the courtyard where a single ash tree stood in a bed of gravel. She had brought the tree with her, in a manner of speaking. She had been on the committee that approved its planting, had argued for a species that could survive the city's poor air, had won the vote by pointing out that ash trees were, in their quiet way, tenacious. The joke had not landed. She had planted it anyway, metaphorically.
She reached her cubicle and stopped.
The carpet tile in front of her chair was slightly displaced, a corner folded under as though a foot had rested there. The air carried a trace of something unfamiliar, a cologne or a soap she did not recognize, faintly sweet, faintly herbal. Mara stood very still and listened. The archive floor was not silent. It had its own hum, the soft whir of climate control, the distant tap of keyboards, the occasional creak of a chair. But there was, beneath all of it, the particular hush that followed the departure of someone who had meant to leave no trace.
She sat down slowly, her hand still on the folder, her eyes on the floor. Then she looked at the door.
The envelope was pale gray, unsealed, and slid precisely under the gap until only a centimeter of its edge showed. It was the kind of envelope the Ministry used for interdepartmental transfers, the stock slightly heavier than commercial paper, the seal on the back already broken. She pulled it free with two fingers and set it on her desk without opening it.
She looked at the folder she had carried from Aldis Fenn's shop. She looked at the envelope. She chose the envelope because it was already there, because someone had placed it in her space, because she had spent her life sorting the order in which things should be examined and this, she understood instinctively, came first.
Inside was a single photograph.
The image was roughly five by seven inches, the emulsion slightly buckled from heat, the edges feathered with char that had been carefully trimmed away. It showed a child, perhaps six or seven years old, seated on a stone step in front of a door painted the deep municipal green that had been standard in the outer provinces a generation ago. The child had dark hair cut short and uneven, as though done at home with kitchen scissors, and was looking slightly off camera, the way people do when they have been asked to hold still and are failing to do so. The light fell across the child's face from the left, illuminating one cheek and leaving the other in soft shadow.
Mara did not recognize the child.
She studied the photograph for a long time, turning it in her hands, tilting it toward the desk lamp to see if any detail emerged. The door behind the child had a number painted on its frame in white, but the numerals had been partially obscured by a fold in the print. She could make out the first digit clearly: a four. The second was less certain, a curve that might have been a three or an eight. The third was lost entirely in the crease. The stone step was cracked along one edge, a fissure running from the child's foot toward the gutter. There was no other context. No adults. No street. No sign of what city or province this might be.
She set the photograph down and reached for the slip of paper that had been folded beneath it.
The paper was a registry extract, the format instantly familiar to anyone who had worked in the Ministry's records division. It carried the header of the Bureau of Verification, a sub-department she knew only by reputation, and a code in the upper right corner that should have referenced a living person in the active database. Mara read the code aloud under her breath, the numbers and letters falling into the cadence of a recitation she had performed ten thousand times. Then she entered the code into her terminal.
The system returned an error.
She tried again, slowly, checking each character. The same error. The code did not exist in any active database. It did not exist in the archive's redundant backup, nor in the cold storage she had access to as a senior investigator. It did not exist, as far as she could determine, in any system that should have known about it. The code referred to no one. The code had never referred to anyone. The code was a fiction, carefully constructed, designed to fail in precisely this way.
Mara sat back in her chair and let her hands rest on the desk, the photograph to her left, the extract to her right, the folder from Aldis Fenn still under her coat. She looked at the ash tree through the window. The branches were bare, the bark pale gray, the leaves long gone. In a few weeks it would bud again. In a few months it would be full. She had watched it cycle through seven seasons now.
A child she did not recognize. A code that did not exist. An envelope slipped under her door while she was gone.
The archive floor hummed around her. Somewhere a phone rang twice and stopped. Somewhere a drawer opened and closed. Mara reached into her coat and pulled out the folder from Aldis Fenn and set it beside the other items, three pieces of a puzzle she had not known she was assembling.
She did not open the folder yet.
She picked up the photograph and looked at the child again, at the off-camera gaze, at the cracked step, at the partially obscured numerals. She looked at the way the light fell. She looked at the small, uneven haircut and tried to imagine who had cut it, and when, and why. She did not feel a surge of recognition. She did not feel a click. She felt only the steady, quiet pressure of something she did not yet understand pressing itself against the edges of her life.
She turned the photograph over. On the back, in a hand she did not recognize, was written a single word in ink that had faded to brown.
"Vance."
Mara set the photograph down very slowly, as though it had become heavier in the last second. She stared at the back of it, at the word, at the faded brown of the ink. She thought of her name. She thought of the registry fire that had taken her parents. She thought of the family that had taken her in, that had never told her where she came from, that had given her a name she had carried without questioning.
She picked up her desk phone and dialed a number from memory, a number she had not called in seven years.
The line rang four times. A voice answered, smooth and unhurried, a voice she had not heard in longer than she cared to remember.
"Mara," Dorian Hsu said. "I wondered when you would call."
She looked at the photograph. She looked at the word on the back. She looked at the ash tree through the window, its branches still and pale against the gray of the courtyard wall.
"We need to talk," she said.
"I know," Dorian said. "Come to the old place. Come alone. And Mara?" A pause, the line so quiet she could hear the faint static of the connection. "Bring the photograph."
The line went dead. Mara set the receiver down and looked at the three items on her desk, arranged in a neat row under the lamp's pale circle of light: the photograph of a child she did not recognize, the registry code that did not exist, and the folder from a man who had once walked through the ruins of her childhood.
The archive floor continued its soft, industrious hum. The ash tree stood in its bed of gravel, bare and patient, waiting for a season that had not yet arrived.
Mara reached for her coat.
