She had spent two weeks waiting for memory to arrive on its own schedule, and had begun, gradually, to resent the waiting as much as she resented anything in this borrowed life. Memory had come to her at a bronze bell, in a museum basement, in a dream she hadn't chosen. It had never once come because she asked.
So she asked.
It was Tang Mei, unknowingly, who gave her the method. "My grandmother swears smell brings memory back faster than anything," she'd said one evening, apropos of nothing, describing a great aunt who could not remember her own address but could recite, in perfect detail, a wedding banquet forty years gone the moment someone burned the right incense near her. "Something about how scent skips the part of your brain that argues with itself." She'd said it lightly, more interested in the noodles between them than in the observation itself, entirely unaware she'd just handed Su Wan the closest thing to a method she'd found in two weeks of waiting for the past to arrive uninvited.
Su Wan had filed the comment away without comment, and had spent the following days testing it with the discipline she brought to everything she considered worth doing properly. She returned to the museum on a public afternoon this time, moving through galleries she'd already catalogued, touching nothing, simply standing near objects long enough to notice what her body did before her mind caught up to it. A lacquer screen produced nothing. A rack of ceremonial swords produced only distaste, sharp and immediate, though she could not say whether it belonged to her or to the body she wore. A recording of reconstructed court music, played through museum headphones, made her hands go still in a way she chose not to examine too closely in public.
None of it broke through the way the bell had. She began to suspect the bell had been an exception rather than a method, until she remembered the report's appendix, the sketches, the annotated hand she'd recognized. Not everything from that excavation had gone to the museum's public galleries. Some of it, cataloged and quietly overlooked, sat in the same basement as the mirror, waiting, she suspected, for someone patient enough to ask the right object the right question.
Lu Zhou got her back into the archive without asking why, which she had come to understand as its own kind of trust, the sort that didn't require an explanation to be extended. He unlocked the same drawer with the same unhurried care, and she noticed, not for the first time, how easily the gesture came to him, a familiarity with these shelves that no ordinary graduate assistant should have accumulated in two years of borrowed access. She set the observation aside, the way she had learned to set aside every uncomfortable fact about him that didn't yet have anywhere useful to go.
Among the drawers he'd already shown her sat a small ceramic tray of personal effects, recovered, according to the card, from the same foundation layer as everything else. A hairpin. A broken comb. A bronze seal, its handle carved into the shape of a crane with its wings folded, its face worn nearly smooth.
She lifted the seal because it was the only object on the tray that made her hand hesitate before touching it, an old, wordless caution she'd learned to treat as information rather than superstition.
The memory arrived before her fingers had fully closed around it.
Fifteen seconds. She would count them precisely, afterward, lying awake trying to stretch them into something longer through sheer force of attention, and failing. A room she didn't recognize, lit by lamplight rather than lanterns, someone's hand closing over hers around this same seal, pressing it into her palm with an urgency that had nothing to do with ceremony. A voice, low, fast, the words arriving without the face that spoke them, the way every memory of this kind arrived, cut loose from its speaker as though someone had gone back afterward and carefully removed the one detail that would have made the memory useful.
If I die, burn the western archive first.
The seal slipped from her fingers and struck the tray with a small, flat sound, and the memory was gone as completely as it had come, leaving her with fifteen seconds she could not extend and a sentence she could not place.
"Su Wan." Lu Zhou's voice, careful, closer than she'd registered him moving. "What did you just hear?"
She told him. There seemed, finally, no version of continuing this that didn't require it. She watched him receive the sentence the way she imagined he received a difficult passage of classical text, turning it over for grammar before allowing himself to feel its meaning, and found something steadying in the delay, a mind that refused to react before it had understood.
He didn't ask her to repeat it, which told her he'd believed her immediately, and didn't offer a theory, which told her he understood there wasn't yet one worth offering. "The western archive," he said instead, slowly, testing the phrase the way he tested everything. "There's a western wing listed in some of the oldest palace surveys. Nobody's ever located it precisely. Most historians assumed it was destroyed in the same fire that ended the reign."
"Assumed," she repeated. "Not confirmed."
"Not confirmed," he agreed, and something in the way he said it told her he had already begun, somewhere behind his careful stillness, to want to go looking. It was, she thought, the first time she had watched curiosity move visibly across his face rather than stay carefully filed behind it, and she found she did not entirely trust how much she liked seeing it.
She did not tell him that the voice in the memory had not sounded afraid of the fire. It had sounded afraid of what would be found if the fire didn't happen quickly enough. That distinction seemed, walking home through a city that had no idea what she was carrying, too fragile to survive being spoken aloud before she understood it herself.
There was, underneath the discovery, a smaller and more uncomfortable one she chose not to share with him either. She had been so certain, gripping the seal, that the memory would resolve into something conclusive, a face, a name, an answer rather than another question. Fifteen seconds had given her exactly the opposite of certainty, and she recognized, with the particular discomfort of someone catching her own reasoning mid mistake, that she had spent two weeks assuming each new fragment would clarify the last one. None of them had. Each had only proven that the thing she was looking for was larger, and older, and better hidden than the one before it.
Fifteen seconds had given her a location no one could confirm and a warning she couldn't fully interpret. It had also given her, for the first time since waking in a stranger's hospital bed, proof that memory could be summoned rather than simply endured. That felt, walking home in the last grey light of the afternoon, less like triumph than like a door she had only just realized she could open from both sides.
