The call came at eleven, between a condition report on a christening bonnet and the second coffee Ilse allowed herself before noon.
"I'm calling about my aunt's lace." The voice on the line was a man's, careful, the kind of careful that came from reading a solicitor's letter twice before dialing. "Marthe Vandamme. She passed in March. There's no one left in the family who wants the collection, and the notary said your museum takes donations."
Ilse wrote the name on the pad beside her keyboard, block letters, the way she wrote everything that mattered. Vandamme. Bruges families with lace in their attics were not rare; half the city had a grandmother who had bobbins somewhere, wrapped carefully in tissue paper gone the color of weak tea. Most of what came through that particular door turned out to be ordinary nineteenth-century commercial work, competent and unremarkable, the textile equivalent of a family photograph nobody could name.
"We'd be glad to look at it," she said. "Do you know roughly how many pieces?"
Bram De Wilde had run De Kantwerf's conservation department for thirty-one years. In that time he had seen every variety of anomaly a lace panel could offer. Mismatched repairs. Later restorations grafted onto older grounds. Workshop shortcuts taken under wartime thread shortages. Apprentice hands correcting themselves mid-panel in ways that left a visible seam in the pattern's logic.
On the wall of his own small office he kept a framed fragment of ruined nineteenth-century point de Gaze he called his favorite failure. He had once spent four months trying to date the piece. Then a single stray synthetic fiber, invisible to the naked eye, revealed that it was a 1960s forgery good enough to have fooled two previous experts. He liked to say the fragment kept him honest. Ilse had always privately thought it kept him cautious in a way that occasionally shaded into something less useful than caution.
He looked at the Vandamme panel for perhaps ninety seconds, under his own loupe, before he straightened and handed it back.
"Personal variation," he said. "Some makers counted their own way and never corrected it, especially in a family workshop with no guild inspector checking their output against a master pattern." He returned the loupe to its drawer while he spoke. "I've seen counts run high before. Rarely this consistent, I'll grant you, but consistency isn't evidence of anything beyond a maker with a strong habit."
"Sixteen repeats, Bram. Not one deviation, in the ones that follow the baseline at all."
The woman who taught her the code called herself Zuster Agnes. Margriet understood within the first ten minutes that she was no more a nun than the pillow between them was a Bible. She was perhaps sixty, thick through the wrists in the way of a lifetime spent at bobbin work. She conducted the entire lesson with her eyes on her own hands, never once on Margriet's face.
"Van Acker says you're fast," Zuster Agnes said. "Fast is not what I need from you. Fast is how mistakes happen. I need exact, and I need it to look, to any eye but mine, exactly like fast."
They sat in the back room of a house on a street Margriet would afterward be unable to picture clearly. That deliberate blankness she understood only later was itself a kind of protection: the less she could describe, the less she could betray. A single lamp lit the pillow between them; the shutters were closed against a daylight that would have shown nothing incriminating at all. Which was, Zuster Agnes said without looking up, exactly the point. Suspicion did not need evidence; it needed only a habit of looking. A shuttered window taught a habit of looking faster than an open one did. The room smelled of cold ash and, faintly, of the linseed oil someone had once used on the floorboards. A second chair sat empty by the door, unexplained, the kind of small detail Margriet learned, over the following months, never to ask about.
"You'll want to know who else uses this room," Zuster Agnes said, not looking up, as though she had read the question in the set of Margriet's shoulders. "You will not be told. I was not told, when I began. Whatever you can picture of this place beyond this table and this lamp, forget it before you leave tonight. A memory you don't have cannot be taken from you."
They arranged a video call for the following evening, seven her time. Thomas Ashworth appeared on her screen from what looked like a university office buried under paper. Actual paper, stacked in towers that leaned at angles a conservator's instinct found faintly alarming. One stack sat close enough to the desk lamp's cord that she found herself, absurdly, wanting to reach through the screen and move it somewhere safer. Younger than she had pictured from his prose, perhaps forty. The rumpled, slightly windburned look belonged to a man who spent more time in archive reading rooms than outdoors. His wardrobe had not entirely adjusted to either.
"Sorry about the state of this," he said, by way of hello, gesturing at the room behind him without turning to look at it. Its condition was, as far as he was concerned, a permanent, faintly embarrassing weather system he had long since stopped trying to control. "Right. Show me. Please. I've barely slept."
One at a time, in sequence, she held the sixteen printed repeats up to the camera. The picot counts and the three breaks in the baseline came out as she had documented them for herself two days before. His face held her attention more than the camera, tracked in the small window in the corner of her own screen. That habit had come from these calls. Talking to a lens instead of an expression still felt strange.
Through the crate he worked with the unhurried thoroughness of someone with nowhere else to be. Each folded parcel he lifted, unwrapping enough to confirm it was lace and nothing else, refolding, setting it aside. His breath fogged faintly in the cold morning air with each exhale, a small ordinary detail Margriet found herself fixed on. She could not look away from it. The shape of his breathing might somehow tell her, before his hands did, whether this morning would go well or badly.
Margriet counted his hands the way she counted stitches. One parcel. Two. Three.
She could not hear anything from this distance, only see the shape of it. The soldier lifted the panel fully clear of its paper. Against the grey morning light he held it the way a man holds something he has decided, unexpectedly, to actually look at rather than merely process. He turned it. Something passed between him and Van Hecke, words Margriet could not catch. Van Hecke, unbothered, answered and gestured at the panel with the easy pride of a man who sold beautiful things and liked being told they were beautiful. His free hand moved through the air the way it always moved when he spoke about his own stall's finer pieces. That habit Margriet had seen a hundred times at the Markt. Until this morning she had never once watched it with her heart in her throat.
The notice went up on the guild hall door on a Tuesday. It was one more sheet of German administrative paper among the dozens that had accumulated there over a year of occupation, curling at the corners, half of them already illegible from rain. Margriet almost walked past it, the way she had trained herself to walk past most such notices. Reading them too closely only ever confirmed things she already suspected and could do nothing about. Over that year the door itself had become a kind of ledger of the occupation's slow accumulating demands: requisition orders for copper and wool, curfew amendments, a notice from the previous autumn about bicycle tires that had never been fully rescinded. Half the city still obeyed that tire notice out of habit rather than enforcement.
A neighbor stopped her at the corner instead. "Your Hilde's on the list," the woman said, not unkindly, the way people delivered bad news in a city that had grown practiced at it. Her hand rested briefly on Margriet's sleeve, a small human gesture that Margriet would remember afterward more clearly than most of what followed it. "The labor registration. Girls born in her year, for the textile mills they've requisitioned in the Ruhr. You'll want to see it yourself."
Thomas called on a Wednesday evening with the energy of a man who had found something he did not yet fully trust himself to believe. Before he let himself believe it, he wanted a second pair of trained eyes on the evidence. Ilse had been expecting the call since his text that afternoon: three words and nothing else, you need to see this. She had read the message four times over the course of the day without managing to guess what it might mean.
"German counter-intelligence records," he said, without preamble. He shared his screen before Ilse had fully settled into her chair. The tower of paper behind him looked, if anything, slightly taller than the last time she had seen it. "Bruges garrison, early nineteen-sixteen through early nineteen-eighteen." He scrolled past a requisition form without looking at her. "Most of it is routine administrative correspondence. Requisition orders. Curfew enforcement logs. Deeply boring stuff that nonetheless takes forever to get through." He grimaced. "You cannot skim archival German shorthand. You have to actually read it. But a name keeps recurring across eleven months of these files. It attaches specifically to investigations into textile exports."
Margriet did not trust her hands to move again until she heard the workroom door close fully behind him. Even then she sat a long moment with her fingers folded in her lap. She felt the particular ache of stillness held too long, the muscles in her forearms tight from a tension that had nothing to do with thread.
Coleta caught her eye from two pillows down, and said nothing aloud. She only held Margriet's gaze a moment with an expression that carried its own plain warning, one careful worker to another, and returned to her own sixty-four pairs without another word. It was, Margriet understood, the closest either of them would ever come to acknowledging aloud what had happened. The closest either of them could safely come. Every other pillow in the room held a woman who might, however innocently, repeat whatever she overheard.
Sister Godelieve found her at the door as she gathered her things at the end of the morning session. Low enough that no one else in the room could hear it, she said only, "He asks that question of someone new every few weeks." A second line followed. "He has not yet asked it of the same maker twice."
Something else had come clear across these weeks of laying key against thread. The fuller list had taught her to read what her first caliper pass had smoothed flat: the fine tension of the ground inside every repeat, not only the three that broke the picot count outright. What she had once logged as thirteen inert baseline repeats she understood now as thirteen positions in their own right, each nineteen-count ground holding a density her earliest measurements had averaged into sameness. The border did not carry three markers against a blank field. It carried a value in all sixteen, and she had simply lacked, at the start, the key to read the other thirteen as anything but repetition.
She read it to him now, position by position, repeat one through sixteen. A number, resolved through the picot-addition system Cauwels and Thomas's fragment had both independently confirmed. Then a unit designation. A blank, where the substituted flower from repeat three still matched nothing on either list. Another number. A blank. A blank. An urgency marker. Four more blanks, running consecutively. An element she had logged from the start as ordinary border decoration. Then three numbers in sequence, near the end. A last repeat of plain ground.
"Read me just the numbers," Thomas said. "In order, ignoring the blanks and the unit markers for now."
The handoff was supposed to take four minutes. Margriet had done it this way twice before, since Van Acker moved her off the direct checkpoint route. A folded panel passed hand to hand in the covered passage behind the fish market, where the morning crowd gave enough cover that two people exchanging a parcel drew no more notice than any other transaction among the stalls.
The passage itself smelled, every morning without fail, of brine and scaled fish and the cold stone that never fully dried. Against her own will, Margriet had come to associate that smell with the particular flavor of this specific fear, distinct from the fear of the checkpoint or of Voss's careful questions. This fear lived now permanently in her nose as much as in her chest.
The boy she handed it to this time called himself Willem, though she suspected, the way she suspected most names in this work now, that it was not the one his mother had given him. He was younger than her, perhaps seventeen, with the particular nervous energy of someone new enough to the work that his hands had not yet learned Zuster Agnes's stillness. Margriet recognized in him, too, the same quiet determination she remembered from her own first weeks.
He had a way of glancing twice at anything unfamiliar, a habit she recognized because she had broken herself of it only through months of deliberate practice. Watching him approach through the passage this particular morning, she found herself wishing there were some way to hand him her own stillness along with the parcel. She knew, as clearly as she knew anything in this work, that stillness could not be given, only earned, slowly, the same hard way she had earned it herself.
"Same as before," she said, low, passing the wrapped panel into his coat as they crossed paths in the passage's narrow shadow. "Van Hecke's stall, before eight."
