3. The Hartsfield Protocol

The knock came again, three precise raps that spoke of a man accustomed to being answered. Margot stood frozen in the narrow hallway of her apartment, one hand still resting on the latch, the other gripping the strap of her shoulder bag. Inside the bag were the documents from the mill—the ledgers, the transfer agreement, Sister Marguerite's journal. Inside her apartment was a boy who did not legally exist.

"Ms. Vasseur." Voss's voice was muffled by the oak door but unmistakable. "I saw your light from the street. I apologize for the late hour, but a matter has arisen that requires your immediate attention."

Margot turned to Tobias. He had pressed himself against the wall of the corridor, his grey eyes wide and watchful. She put a finger to her lips and pointed toward the bedroom at the far end of the hall. He understood instantly, moving with that strange, fluid economy she had noticed in the stairwell—no wasted motion, no sound.

She waited until the bedroom door clicked shut. Then she smoothed her hair, arranged her face into an expression of mild irritation, and opened the door.

Dr. Elias Voss stood on her doorstep in a charcoal overcoat that probably cost more than her monthly retainer. Behind him, the Spiegel Canal glittered with the reflected lights of the old merchants' houses, and a thin rain had begun to fall, misting his silver hair with droplets that caught the light like seed pearls. He was alone.

"Dr. Voss," Margot said. "It's nearly eleven o'clock."

"I am painfully aware of the hour, and I do apologize." He smiled, but the smile did not reach his eyes. "May I come in? What I have to say is better said in private."

Every instinct Margot possessed screamed at her to refuse. But refusal would be suspicious, and suspicion was a luxury she could no longer afford. She stepped aside. "Briefly. I was about to retire."

Voss entered her apartment with the easy confidence of a man who had been in many beautiful rooms and was impressed by none of them. His gaze swept over her bookshelves, her worktable strewn with pigment samples, the framed Caravaggio study she had bought at auction and spent three years restoring. He did not sit.

"I wanted to speak with you about the triptych," he said. "The Annunciation panel in particular. You mentioned yesterday that you had discovered a small flaw in the upper corner. A crack in the gesso, I believe you said."

"I did." Margot kept her voice steady. "It's a common issue with panels of that age. The wood expands and contracts with humidity, and the gesso eventually fractures along the grain lines. I've documented it for the conservation report."

"Yes, I saw the photographs. Very thorough." He paused, and Margot felt the weight of the pause like a stone dropped into still water. "You didn't happen to find anything else during your examination, did you? Anything tucked behind the frame, perhaps? A piece of paper, or some other artifact? Conservators sometimes do, I understand. Hidden messages, old repairs, even the occasional love letter."

There it was. Margot felt her pulse quicken, but she had spent twenty years learning to keep her hands steady while working on canvases worth more than buildings. She knew how to control her face.

"Nothing of the sort," she said. "Why do you ask?"

Voss studied her for a long moment. "The Annunciation panel was acquired from a private collection in the Verviers region three years ago. Before that, it was housed in a small chapel attached to a now-defunct religious institution—an orphanage, I'm told, run by an order called the Compassionate Veil. A rather obscure group. They disbanded in the late 1980s after some unpleasantness. Financial irregularities, I believe."

"I'm not familiar with them," Margot said.

"No, I don't suppose you would be. But the reason I ask about the panel is this: one of the sisters who served at that orphanage was something of an amateur artist. She assisted with the chapel's restoration work in the 1970s. There is some concern among the institute's legal team that she may have left behind certain... personal effects. Letters, journals. Items that might be misinterpreted if they fell into the wrong hands."

Margot thought of Sister Marguerite Delacroix's journal, currently resting in her shoulder bag three meters from where Voss stood. "I haven't found any letters," she said. "If I do, I'll be sure to notify you."

"Excellent." Voss smiled again, and this time the smile seemed almost genuine. "I knew I could count on your professionalism. On an entirely different note—have you seen anything unusual around the institute in the past few days? Any unauthorized persons, any security concerns?"

"You asked me that last week, Dr. Voss. The answer hasn't changed."

"Last week I was asking about a hypothetical. This week I'm asking because one of our custodial staff reported seeing a figure matching the description of a missing patient in the alley behind the loading dock." He watched her face with the patient attention of a man who had spent decades reading micro-expressions. "A boy, approximately sixteen years of age, pale hair, grey eyes. He was wearing a medical gown. You wouldn't have seen anyone like that, would you?"

Margot felt the lie form in her throat like a pearl around a grain of sand. "No," she said. "I haven't seen any boy."

Voss nodded slowly. "I thought not. But I had to ask. The boy is unwell, Ms. Vasseur. He suffers from a rare genetic condition that requires constant monitoring. Without his medication, he may become confused, even dangerous. If you should encounter him, I urge you to contact security immediately. For his safety as much as yours."

"Dangerous," Margot repeated.

"He was being treated in our secure wing. He absconded during a fire drill. We believe he may have been... influenced by outside parties who wish to damage Chromogen's reputation. There are activists, you understand, who object to genetic research on ideological grounds. They would not hesitate to exploit a vulnerable patient for their own purposes."

Margot thought of Tobias huddled in the foreman's office at the Martell Mill, his thin hands trembling as he read the names of the dead donors. She thought of the ledgers, the medical records, the word "Deceased" written beside so many names. And she thought of the note that Sister Marguerite had hidden behind the Annunciation panel thirty years ago, waiting for someone with courage.

"Thank you for the warning," she said. "I'll keep my eyes open."

"I'm sure you will." Voss moved toward the door, then paused with his hand on the latch. "One more thing. The institute will be conducting a routine security audit next week. All personnel, including contractors, will be required to submit their personal devices for inspection. Standard procedure—we do it every few years. You'll receive the formal notice tomorrow."

Personal devices. Her laptop, with its search history of shell corporations and tax filings. Her phone, with the cached search for Lucien Bouchard and the Bouchard v. Order of the Compassionate Veil lawsuit.

"Of course," Margot said. "I have nothing to hide."

Voss met her eyes. "No," he said. "I'm sure you don't."

Then he was gone, his footsteps fading down the staircase, and Margot was alone in her hallway, trembling.

She waited five full minutes before she let Tobias out of the bedroom. He emerged like a ghost, his bare feet silent on the floorboards, and stood before her with a question in his grey eyes.

"He knows," Margot said. "He doesn't know for certain, but he suspects. And he's going to search my devices next week."

"Then we have a week," Tobias said. "Maybe less."

Margot went to her worktable and began to empty her bag. The documents from the mill spread across the surface like a dark tide: ledgers with cracked leather spines, medical charts yellowed with age, the transfer agreement, Sister Marguerite's journal. She opened the journal to the last entry and read it again. I have placed the evidence where only a restorer will find it.

"There's something I don't understand," Margot said. "Sister Marguerite knew about the experiments. She documented them. She hid evidence. But she didn't go to the police. She didn't go to the press. She hid a note in a painting and waited thirty years. Why?"

Tobias sat down at the table across from her. "Maybe she tried. Maybe no one believed her."

Margot thought about this. It was 1989 when the orphanage closed. The Bouchard lawsuit had been dismissed the year before, rejected by a court that ruled the victims had waited too long to come forward. The Order of the Compassionate Veil had been allowed to quietly dissolve, its assets sold, its records sealed. Who would have believed a single nun, a nurse who had participated in the system she was trying to expose?

She pulled the transfer agreement toward her and examined the list of signatories again. HelixGene Therapeutics. Dr. Elias Voss—the elder Voss, presumably, though the signature was identical in its precise, almost architectural quality to the younger Voss who had just stood in her hallway. And a third name she had not noticed before: Albrecht Morgenstern, Chairman of the Board.

Morgenstern. The name was familiar in the way that the names of very rich men are familiar—glimpsed in financial pages, attached to charitable foundations, whispered in the same breath as phrases like "old money" and "influence." Margot searched her memory and found a fragment: Morgenstern had made his fortune in pharmaceuticals in the 1960s, then diversified into biotechnology in the 1980s. His family trust was one of the largest charitable donors in the northern cantons. He had funded hospitals, universities, art museums.

He had also, according to this document, funded HelixGene Therapeutics with 1.2 million Lundenburg crowns, paid to the Order of the Compassionate Veil for assets that included the biological material extracted from orphaned children.

"He's still alive," Margot said. "Morgenstern. He's ninety-two, and he lives in a penthouse on the Platz des Grands Hommes. I read a profile of him last year in the Lundenburg Gazette. He's a philanthropist. A pillar of the community."

"He bought us," Tobias said quietly. "He bought the children."

Margot looked at the boy across the table. In the soft light of her apartment, he looked younger than she had first thought—not sixteen, but perhaps fourteen, or even thirteen. His skin had the translucent quality of someone who had rarely seen sunlight, and his hands, resting on the table, were fine-boned and still.

"How old are you?" she asked.

"I don't know. I don't have a birthday. They woke me up two years ago, I think. Maybe three. Time was hard to track in the sublevel." He paused. "I wasn't born. I was decanted."

The word hung in the air between them. Decanted, like wine from a bottle. Decanted, like a thing rather than a person.

"Tobias," Margot said, and then she stopped because she did not know what to say. She had spent her career restoring damaged objects, but the damage here was not something that could be fixed with solvent and a sable brush. The damage here was structural, systemic, built into the very architecture of the city she called home.

"We need to get into the sublevel," she said. "The documents prove what happened at Saint-Éloi, but they don't prove Chromogen is still doing it. For that, we need current records. Laboratory logs. The Hartsfield Protocol itself."

"How? Voss is already suspicious. He'll be watching you."

"Not if I give him a reason to stop watching." Margot's mind was racing now, assembling possibilities like fragments of a shattered fresco. "He thinks I'm hiding something. What if I give him something to find? Something innocuous. An affair, perhaps. Or a minor theft. Something embarrassing but not criminal. He'll think he's found my secret, and he'll stop digging."

"You would do that?"

"I would do whatever it takes." The ferocity in her own voice surprised her. "I've spent twenty years cleaning up the messes of wealthy people who didn't want their art damaged. I've preserved their legacies, burnished their reputations, and asked no questions. I'm done with that. I'm done being their invisible hand."

Tobias looked at her for a long moment. Then, very slowly, he smiled. It was the first smile she had seen from him, and it transformed his face—the vacancy in his eyes receded, replaced by something that looked almost like hope.

"Then we need allies," he said. "People who can help us. People who know things we don't."

Margot thought of her friend at the Valerius Museum, the curator with the country house in the Verviers Hills. Celestine Moreau was fifty-seven years old, sharp-tongued, and possessed of a moral compass that pointed true north even when it was inconvenient. She had been fired from two museums for refusing to authenticate forgeries that wealthy donors wanted to donate for tax write-offs. She knew everyone, and she owed no one.

"Tomorrow morning," Margot said, "we're going to visit a friend."

They left the apartment before dawn, slipping out through the service entrance while the city still slept. Margot had packed a small bag for Tobias—clothes that had belonged to a former lover, now long departed, whose build was similar—and they took a tram to the Valerius Museum, where Celestine Moreau kept an office on the third floor, behind the Egyptian collection.

The museum was not yet open to the public. Margot used her contractor's pass to enter through the conservation wing and led Tobias through a maze of storage rooms and research libraries until they reached Celestine's door. She knocked three times, then twice, the old signal from years past.

The door opened. Celestine Moreau was a tall woman with iron-grey hair pulled back in a severe bun, and her eyes, behind her tortoiseshell spectacles, missed nothing. She looked at Margot, then at Tobias, and stepped aside without a word.

Inside the office, surrounded by sarcophagus fragments and stacks of catalogues, Margot told her everything. The note. The mill. The ledgers. The transfer agreement. Sister Marguerite. The Bouchard lawsuit. Chromogen. The Hartsfield Protocol. Tobias.

When she finished, Celestine was silent for a long time. Then she removed her spectacles, polished them on the hem of her cardigan, and said: "I knew about Saint-Éloi. Not the experiments—no one knew about those—but the lawsuit. I was working at the Musée Régional de Haute-Vienne in 1988 when the case was dismissed. There was a journalist then, a woman named Nadia Marchand, who tried to keep the story alive. She wrote a series of articles for a provincial paper, but no one picked them up. The Order had friends in high places. The Church intervened. She was threatened, and eventually she dropped the story."

"Is she still alive?" Margot asked.

"Last I heard, she was living in retirement on the coast. I can try to reach her." Celestine put her spectacles back on and fixed Margot with a level stare. "But you need to understand what you're doing, Margot. You're not just investigating a company. You're investigating a network—old money, old power, old secrets. The Morgenstern family alone has more influence than you can possibly imagine. If you pursue this, you will lose your career. You may lose your freedom. Are you prepared for that?"

Margot looked at Tobias, who was standing by the window, watching the morning light creep over the museum's rooftop garden. "I've already lost something more important than my career," she said. "I've lost the illusion that I was living an honest life. Everything I own, everything I've built—it was all purchased with the proceeds of this system. My apartment, my reputation, my expertise. I was their decorator, Celestine. I made them look beautiful while they were doing unspeakable things underground."

Celestine nodded slowly. "Then let's get to work."

She opened her laptop and began typing. Within an hour, she had found a phone number for Nadia Marchand in a coastal town called Port-aux-Mouettes. Within two hours, she had spoken with the retired journalist and arranged a meeting. Within three hours, she had pulled archived court records from the Bouchard case that had not been digitized—records that had been sealed by judicial order and should have been impossible to access.

"How did you get those?" Margot asked.

Celestine smiled thinly. "I have a colleague in the court archives who owes me a favor. A large favor. I cashed it in."

The documents were dense and technical, but one name appeared repeatedly: Sister Marguerite Delacroix. According to the court filings, she had been the plaintiffs' primary source of information. She had provided them with medical records, internal correspondence, and a sworn affidavit detailing the procedures conducted at Saint-Éloi. She had agreed to testify. And then, three months before the trial was scheduled to begin, she had vanished.

"Vanished?" Margot said.

"No body was ever found. The official report said she had left the order voluntarily and relocated to an undisclosed location. The case collapsed without her testimony. The judge cited the statute of limitations and dismissed."

"She didn't vanish," Tobias said quietly. "She was silenced. Like the note said. Ask before they silence you too."

Margot thought of the last entry in Sister Marguerite's journal. I have done what I can. Forgive me for the rest. She had known. She had known what was coming, and she had hidden the evidence anyway, hoping that one day, decades later, someone would find it and finish what she had started.

"We need the Hartsfield Protocol," Margot said. "The current version. The files from the sublevel. Without those, all we have is a thirty-year-old case that was already dismissed once."

"Then we need to get into Chromogen," Celestine said. "And I may know how."

She explained. The Valerius Museum was hosting a fundraising gala in two weeks, an event that would attract Lundenburg's wealthiest and most influential citizens. Among the attendees would be Albrecht Morgenstern himself, along with several members of the Chromogen board. The museum's security protocols for such events were rigorous but predictable. With proper planning, it might be possible to use the gala as cover for an infiltration.

"It's dangerous," Celestine said. "If you're caught, you won't just be fired. You'll be arrested. And given who we're dealing with, you might not make it to trial."

"Then I won't get caught," Margot said.

She looked at Tobias, who had been silent for most of the conversation. His grey eyes met hers, and she saw something in them that had not been there before—not hope, exactly, but a kind of steady resolve, a willingness to fight.

"I want to come," he said. "I know the sublevel. I know the security patrols, the keycode sequences, the places where the cameras have blind spots. You can't do this without me."

"He's right," Celestine said. "You can't."

Margot nodded. "Then we plan. We have two weeks. We need maps, access codes, and a way to neutralize the security systems long enough to get in and out. And we need to distract Voss while we do it."

She thought of the false secret she had imagined planting—the affair, the minor theft—and dismissed it. That was amateur thinking, and she could not afford to be an amateur. She needed something bigger, something that would pull Voss's attention away from the institute entirely.

"Celestine," she said, "do you still have contacts at the Gazette?"

"Several. Why?"

"Because I think it's time someone wrote a follow-up to Nadia Marchand's story about Saint-Éloi. Not the whole truth—just enough to make Chromogen nervous. An anonymous tip about the orphanage, the lawsuit, the sealed records. Enough to get the press sniffing around. Voss will be too busy managing the public relations crisis to watch me."

Celestine's eyes glinted behind her spectacles. "That," she said, "is a very good idea. I'll make the call this afternoon."

Outside the museum, the sun had fully risen, and the city of Lundenburg was waking to its daily rhythms—the trams rattling along their tracks, the canal boats ferrying commuters, the cafes opening their doors to the morning trade. Margot stood at the window and watched it all, and for the first time in days, she felt something like clarity.

The city was beautiful. It had always been beautiful. But its beauty was built on foundations she was only beginning to understand, and the price of that beauty was measured in stolen children and silenced witnesses and the quiet complicity of everyone who had chosen not to look.

She would look now. She would look, and she would not stop looking, and whatever she found, she would drag into the light.

"Tobias," she said, "let's go home. We have planning to do."

They left the museum together, the conservator and the created boy, walking through the brightening streets of a city that did not yet know it was about to be dismantled.
