The third morning she woke already writing.

Not physically, not yet: her hands were still under the quilt when she opened her eyes, but the sentence was already there, formed in the space between sleep and waking, the way the best sentences always arrived, when she was not chasing them. She lay still for a moment holding it, afraid to move in case it came apart.

He is careful, she thought, because he is protecting something. The question is whether he is protecting it from the world, or from himself.

She got up and wrote it in the leather-bound book before she washed her face.

Below, the shop was quiet in the way that indicated it was still early, that Cassian had not yet come downstairs. She had worked out the rhythm of him over three days: he woke early but moved quietly for the first hour, the sounds of someone who was present in the space but not yet ready to fill it. She had come to think of this as his morning, distinct from the morning they shared when the tea was made and the shop opened, and she had, without discussing it, started coming downstairs after rather than during it.

She made the tea herself this morning.

She was standing at the small table near the front of the shop with her cup when she heard him on the stairs, and she had already poured his cup when he appeared at the bottom, and he stopped when he saw her standing there with both cups, and there was a brief moment of recalibration on his face before he said, evenly, "Good morning."

"Good morning," she said, and held out his cup.

He took it. He held it the way she had come to recognize: not quite the way you held a cup you were about to drink from, but slightly cupped in both hands, as though the warmth was the point. She had noticed this the first morning and had not said anything about it. She was not going to say anything about it. But she had noticed it.

"I want to understand my ability better," she said, when they had both had a moment with their cups. "What it can do. What it cannot. Where the edges are."

He was looking at her in the careful way. "What prompted this?"

"I touched a book yesterday morning," she said. "A very old one, in your collection, the one in the section labeled Distance. I did not mention it because I was not sure what I had felt. Last night I understood it: the Afterglow in that book was not from one person. It was layered. Many people over a very long time, the way sediment layers. And I could feel the difference between them: older impressions were duller, flatter, the emotional color worn down. Recent ones were sharp."

He was quiet, but the quality of it was different from his other quiet: engaged rather than withholding.

"You can feel the age of the resonance," he said.

"And the emotional intensity. And possibly the relationship between the reader and the book: whether it was important to them, whether they came to it for comfort or for information or for something else."

He put his cup down. He was beginning to do this when a conversation became more important than the tea.

"This is more than standard Future Sight," he said.

"Is it?"

"Future Sight is typically limited to contact with people," he said. "Reading objects requires a secondary skill. Not everyone with Future Sight can do it." He paused. "My grandmother had Future Sight. She could read people but not objects. You are reading both."

She looked at her hands, which was a habit she seemed to be developing, looking at her hands when she was thinking about what they could do.

"Can you tell me," she said, "about what happened to your Afterglow? More than what you told me yesterday."

He picked up his cup again, which was the reverse of before. She interpreted this as: what I am about to say requires the comfort.

"I found it when I was nineteen," he said. "I had not been looking for it. I was doing archive work with my family, cataloguing records, and I found a fragment that was connected to my own record." He paused. "In the fragment, I saw something happen to someone." Another pause. "I tried to alter the future. I could not. The event was too strongly set, or I was not skilled enough, or both. I could not remove the event from the future without removing the future entirely." He stopped.

She waited.

"So you removed it," she said.

"I removed my Afterglow from the record," he said. "Which meant the event within it could not be read by anyone, could not be altered by anyone working from the record, could not be acted upon."

"Could not be prevented by anyone but you," she said.

He looked at her. "Yes," he said. "Could not be prevented by anyone but me."

"And have you prevented it?"

"I do not know," he said. "I have spent five years trying to understand enough about how Afterglow works to know whether what I did was sufficient." He held the cup in both hands. "My Afterglow no longer exists in the record. But fragments of what was in it still exist: in objects, in places, in the memories of people who saw it before I erased it. These fragments are what I have been trying to trace."

She looked at him and thought about five years of living without a recorded future. Five years of removing yourself from the thing that told your world who you were and where you were going.

"And if you trace the fragments," she said, "you will understand whether the event is still possible."

"Or whether removing the Afterglow changed enough," he said.

"And my Future Sight can read the fragments."

"I believe so," he said. "An Afterglow that no longer exists in the formal record can still leave traces that a sufficiently sensitive reader can detect. You can read objects, which means you may be able to read the physical traces: the ring I wear contains a fragment, deliberately preserved. There are other objects in the city connected to my former record. And there are people who knew my Afterglow before it was erased, who carry an impression of it in their own memories."

She thought about the darkness she had touched when she put her hand in his, the presence-without-image of it, the sense of something that had been cleared rather than never there. She thought about the edge of an image she had caught, very faint, at the far border of the darkness.

"And you need my help to find them," she said. "The fragments."

"Yes."

"And in exchange you will help me find a way back to where I came from."

"Yes," he said. "When we understand what I need to understand. I believe the same mechanism that brought you here will be relevant to returning you. The leather-bound book."

"Agnes's book."

"It was not entirely your grandmother's book," he said, carefully. "But yes, the book she kept for you."

She looked at him with very specific attention. He looked back.

"You knew my grandmother," she said.

"I knew of her," he said. "I knew who she was." He set the cup down. "I will explain more as we proceed. I am not being evasive for its own sake. I am telling you what I know in the order that I believe will allow you to trust it."

She considered this for a long moment.

"That," she said, "is a very careful way of saying you are giving me information at the pace you think I can process it."

"Yes," he said. "Is that acceptable?"

She thought about her mother, who had communicated primarily through information withheld until the last possible moment and then released all at once in a way that had been exhausting to grow up with. She thought about Clara, who told her everything immediately and in the wrong order and trusted her to sort it out. She thought about the difference between the two and where Cassian fell on the spectrum.

"It is acceptable," she said, "if the pace is reasonable."

"I believe it is," he said.

"I believe I am the better judge of that," she said. "But we can proceed on your terms for now."

Something shifted on his face, very slightly, the calibration happening in real time. He was learning, she thought, that she would hold him to things.

"The first fragment I want you to examine," he said, "is in the ring." He held out his right hand, showing her: a simple band of dark metal on the middle finger, undecorated, old.

She looked at the ring. Then at his hand. She had touched his hand before and she knew what the contact felt like, the particular quality of the darkness, and she was aware that she was about to do it deliberately and with full understanding this time, which was different from the previous times in a way she could feel in her breathing.

"All right," she said.

She put her fingers on the ring.

The darkness came immediately, familiar now, and she moved through it the way she was learning to move through uncertain spaces: not reaching but allowing, letting the resonance find her rather than searching for it. The ring was different from his skin: more specific, more contained, a single thread of something rather than the ambient presence of the whole.

And down the thread, if she followed it, there was something.

She followed it.

The image that came back was fragmentary and layered, two images overlaid, and she sorted them: first, a room she did not recognize, old stone walls, light from windows she could not see the source of, and a young man, younger than the Cassian she knew, perhaps nineteen, sitting at a table covered in papers, bent over something she could not see. Second, overlaid on this, another image: Cassian again, but the setting was different, not a room, something outside, and he was not alone. There was another person with him. She could not see the other person's face clearly, only the edge of them, the suggestion of auburn hair, a coat she did not recognize.

She let go.

"Two images," she said, when she had her breath. "You at approximately the age you described, in an archive. Working." She paused. "And a second image. You are outside, somewhere I do not recognize. There is someone with you. I cannot see who."

He had gone very still in the way she was learning meant something had registered that he was not going to name immediately.

"The ring was made when I was nineteen," he said. "Before I removed the Afterglow." He paused. "The second image is from the Afterglow record. From what was in it."

"The person you saw something happen to," she said.

"Yes."

"I could not see their face," she said.

He said nothing.

She looked at him. He was looking at the table.

She could have said: I will keep trying, I will find a cleaner read of the fragment, I will tell you who it is. She could have said that.

Instead she said: "We should make a list. Of the other fragments, the other objects and people. So we know what we are working with."

He looked up. "Yes," he said. "That is a good idea."

She went and found paper, because the shop had paper in abundance, and she sat down across from him and uncapped a pen, and they made a list together, she writing and he speaking, and she was aware as they did it of the specific texture of working with another person toward a shared goal, the way intelligence moved between two people when it was not being guarded, and she thought: this is the part I am good at. Not the endings. This. The middle, when everything is still possible.

They sat there for a long time. The tea cooled. Neither of them noticed.

When they had finished the list, he said: "Thank you. For this."

"You keep thanking me," she said. "We have an agreement. Thanks is not required."

"It is not for the agreement," he said.

She looked up from the list. He was looking at the table again, and she could not see his full expression, but the line of his jaw was less set than usual, the careful composure slightly loosened at the edges.

She did not say anything. She capped the pen and folded the list and handed it to him, and he took it and put it in his breast pocket without looking at what he was doing, which meant he was looking at her, and she met his eyes briefly and then looked back at her cup.

"Tomorrow," she said, "we should go to the first location on the list."

"Yes," he said.

The morning settled around them. Outside, the city moved through its ordinary hours. Inside, two people who did not fully trust each other sat across a small table with cold tea and a list of things they were going to find, and the shop was very quiet, and neither of them moved to leave.

She spent the afternoon working through the list, and he spent the afternoon watching her work through the list, which she noticed and did not mention.

There was a specific quality to his attention, she had observed. He was a person who paid attention professionally, who had spent years trained to look carefully at things and note what he found, and this quality was present in the way he looked at everything. But there was a different version of it that appeared when he was watching her work, which was slightly less professional and slightly more personal, the attention of someone who was genuinely curious rather than someone who was performing curiosity for useful purposes.

She found this interesting.

She did not say so.

She read four more objects that afternoon: a compass that gave her a vision of salt water and a ship's deck; a small painting in a dark frame that gave her the feeling of a very cold winter many years ago; a brass instrument whose purpose she could not identify which gave her nothing at all; and a letter in a sealed envelope which she set aside without opening, because reading someone else's private correspondence even through Afterglow felt like a different kind of intrusion than reading objects.

Cassian noted everything she told him.

"The compass," she said, "has a strong current from the sea. Recent, I think. Within the last decade."

"It came from the Larkhaven estate," he said. "Coastal town, three hours by Silverline." He paused. "When the Silverline runs."

"And the painting?"

"Very old winter," he said. "The description matches the historical record of the winter of three hundred and twelve, which was a particularly harsh one. If you are accurately reading that, your ability extends to significant historical events preserved in object memory." He wrote this in his notes. "That is unusual even among people with strong object-reading."

She looked at her hands again.

"Is this concerning?" she said.

"No," he said. "It is significant." A pause. "Object-reading that extends to historical event-memory suggests your ability is not simply reading present Afterglow. It may be reading accumulated resonance across time. The object retains the emotional truth of everything that happened to it or near it." He paused. "You are reading the full history."

She thought about this. About the gravity of it: every object she touched was potentially a window not into one person's possible future but into the entire emotional history of everything that had touched it. She thought about walking through a city full of objects and what that would mean, and she understood, for the first time, why she felt the ambient warmth from buildings and streets as well as from people. She was not reading individual Afterglows. She was reading accumulated time.

"That must be very loud sometimes," he said, and the gentleness in it surprised her, the specific gentleness of someone who had thought about a thing from the inside out rather than the outside in.

"It is becoming less so," she said. "I am learning to filter."

"Yes," he said. "I imagine you would."

She looked at him.

He was looking at his notes, but his pen had stopped moving, and she could see from the angle of his head that he was not reading what was on the page. He was elsewhere, in the particular elsewhere of someone who has said something more revealing than they intended and is deciding whether to walk it back.

He did not walk it back.

She added it to the picture.

They worked until the lamps needed to be lit, and she helped him light them, which was a small domestic task she had adopted without discussion, and when the shop was warm and lit and closed against the evening, she went upstairs and sat at the small desk in her room and wrote in the leather-bound book.

She wrote: He said I imagine you would. He said it the way you say something you have thought about before you were asked. The way you say something you have been curious about, privately, and have been waiting for the right moment to be curious about out loud.

She wrote: I am building a picture. I have enough pieces now to see that it is a picture of a person who is more than what he shows. This is not unusual. Most people are more than what they show. What is unusual is that I cannot tell whether he knows I am building it or whether he has simply stopped noticing that he is revealing it.

She wrote: I think he has stopped noticing.

She thought about this for a while.

She wrote: That is how it works, probably. You stop noticing that you are being seen by someone who is paying attention, and then you are seen, and then the picture exists, and then you are known in the way that people know each other when they have sat in the same space for long enough that the ordinary moments add up.

She closed the book.

She looked at the ceiling.

She thought about Monday and the email and the manuscript and the ending she could not write, and she thought about all the things she had learned in one week that she had not known before, about magic and about Bellgrave and about the particular texture of a person who loved books as objects and also, when he had time, read them for causation and poetry for understanding.

She thought: the ending I could not write is the ending of a story I did not yet understand.

She was beginning to understand.

She picked up the pen and opened the book again and wrote: Day seven. Still here. Still not sure this is a problem.

She closed it and went to sleep.
