Chapter 2: Father's Equations

Wednesday 28 August. The house on Ellery Street.

Ba, there were green tea sachets in the cupboard above the kettle and only the ones he liked in the box, and Lyra had been putting the wrong ones in for two years and he had never once said so, and she understood on Sunday morning that this was how he said so.

The rain came in off the porch and went along the window frames the way it did, and Lyra sat at the end of the kitchen table with charcoal in her hand and a stack of Ms. Rivera's first-year portfolios in front of her, and she was supposed to be marking them.

She had marked four. She had spent most of the last hour on the same page.

The problem was that the kitchen was doing the thing.

It was doing the thing everywhere, always — that was the part nobody warned you about, if nobody warned you, which nobody did, because there was no warning, there was just a girl who at some point between being five and being six had noticed that her father was a person and not a shape — but kitchens were where she lost herself. Every surface had a line running off it. The fridge had a grey one to the back door and a warm, complicated one to the toaster, because he had owned the toaster for eleven years and it had never once surprised him. The window had a long pale one going out to the fence. Her father's teacup, the blue one with the chip in the handle that he refused to replace, had a gold line into his chest that Lyra could pick up from the far side of the room, and that was the line.

The line to her father was the line.

It was silver-grey, which she had read somewhere meant old and structural — load-bearing, like a beam, which was a stupid word for it but the only one that had ever felt right — and it was wide, and it was steady, and it had a texture like the grain in a plank. Under the kitchen table it was doing the thing it did when he worked, which was to run hot and bright at the exact point where he was thinking, so that she could tell from across the room which of his problems he had hold of.

Right now it was bright at two points at once, and one of them was where his hand was, and the other one was further in, and Lyra had learned over two years to read the distance between those two points as a rough measure of how hard a problem was.

This one was hard. It had been hard since Thursday.

She put the charcoal down and dragged the portfolios towards her and did the honest thing, which was to grade a portfolio by Marco Senn, who was fourteen and had drawn a dog.

---

"You're doing the thing where you hold the pencil and don't move it."

"I do not do a thing."

"You do a thing with your mouth." Wei Chen pushed his glasses up. "It goes a bit flat at the corner."

She put the pencil down deliberately. "You have a headache."

"I have a Wednesday."

"You have a headache and you're doing the thing where the headache is a legitimate reason to work."

He laughed. It was a good laugh, and it cost him something, and he covered it by reaching for the teapot and finding it empty, and Lyra was on her feet before she had decided to be, filling the kettle at the sink with the specific bad temper of a person who has been given a job.

"Do you want the big pot or the small pot?" she said.

"The small one. It steeps longer."

"You always say that and then you drink it too fast and say it's bitter."

"That's because I like it bitter."

"It's not bitter, it's strong." She set the small pot down. "Ba, you were discharged eight hours ago."

"I was discharged eight hours ago," her father agreed, "and I would like to be permitted one morning of not being discussed."

The line between them buzzed along its whole length — not loudly, not the way it had in the hospital, where she had been able to hear the gaps in it over a nurse talking. But it was there, and she heard it, and so did he, because he flinched, minutely, in the middle of pouring, and Lyra filed that away with a kind of cold anger she had been getting better at.

She put the small pot on the hob. She sat back down. She pulled the portfolios towards her again, and she said, instead of the thing she had been saying for two days, "Can I ask you a real question?"

"You can ask me a real question."

"Not a doctor question. You can put the doctor down for a minute."

Wei Chen took off his glasses, which he only ever did when he was about to be careful, and cleaned them on the hem of his shirt, which never worked.

"Ask."

"Are you afraid of it?"

He put the glasses back on. "Yes."

"Okay." She had not expected it to be that easy and she had to sit with it a second. "Okay. That's — okay. I'm afraid of it too, so."

"Yes," her father said, "I imagine you are."

"Not of seeing." Lyra turned the charcoal over in her fingers. "Of the seeing being me. I get to be sixteen and frightened and have a bad week, and then there's this thing that I can't put down, and it doesn't get tired, and it doesn't go to bed, and it's not — it isn't a skill, Ba. Skills have off switches. This doesn't have an off switch, and it's in my head, and you can hear it, and I can hear you hearing it, and neither of us has said anything about that."

The kettle did the thing it did before it boiled, the small climbing hiss, and neither of them moved.

"That's the fairest description of it I've ever heard," Wei Chen said. "Including mine."

"What's yours?"

"Mine is that I've been married to a woman who could do it, and I spent eleven years being polite about it, and then she disappeared, and now our daughter can do it, and I have spent a year and a half pretending I did not know." He turned his cup a quarter turn on the table. "I have been polite about it, Lyra. I want you to know that I know what that was."

She looked at him. He had not said your mother could do it in five years. He had said your mother was sensitive, and your mother had a rich inner life, and once, at a barbecue in the year before, your mother saw things, in a voice she had recognised and had then wished she could unhear.

"You knew."

"I knew."

"When?"

"Before you were born. Before you were four. I have watched you draw since you could hold a crayon, Lyra, and I have watched you stop drawing at about the age of nine, and I worked out what that meant, and I decided that not saying it would be a kindness, and then you were fifteen and it stopped being a kindness and became a lie, and I got very good at it." He said this without any self-pity at all, which made it much worse. "I did not think it was going to cost me my life."

The kettle clicked off. Neither of them got up.

"Did Mum know you knew?" Lyra said.

"Your mother knew everything I knew. Your mother is the reason I knew anything at all."

---

She did get up, eventually, and pour the water, and steep it too long, and he drank it too fast, and neither of them commented, and it was the best thing that had happened in the kitchen in a fortnight.

Then he turned back to the laptop, and the bright point in the line between them moved, and Lyra, who had spent two years learning to pretend she was not doing exactly this, gave up and looked at the screen.

"Ba, that's not converging."

"It is converging. It is converging slowly, which is a different complaint."

"It's not slow, it's wrong." She pulled the chair round to his side of the table, which she was not supposed to do, and which he had stopped objecting to in about March. "You're treating it as a function of the two variables separately and then adding them. It's not that. When they interact, the whole curve changes shape. It's — okay, look. Look at this."

She drew it for him on the back of a portfolio sheet, in charcoal, fast, without looking at her hand.

Two dots. Four lines. She added four more that made it wrong on purpose, so that he would see it.

"You're not looking for a function," she said. "You're looking for a web. You've got two things and you're forcing them into a line, and they don't want a line, they're a — they're a network. Everything's connected to everything else and the amount of connection isn't the same on both sides. It goes up and down. Some pairs are strong and some pairs are almost nothing, and if you average them you get a number that doesn't mean anything."

Wei Chen had gone very still.

"Where did you learn graph theory?"

"I've been in your study for two years, Ba, you leave things open."

"Thirty-one seconds," he said.

"What?"

"Show me again. From the top. And don't let me interrupt you this time, because I want to hear where you were going before I start criticising your notation." He was already reaching for a clean sheet. "Go on. Slowly."

She went again. Slowly.

He interrupted her four minutes in, and she had been right about the web, and he was right about the notation, and they ended up at half past nine in the morning with tea going cold and two pages covered in a hybrid of his graph paper and her charcoal, arguing — properly, hard, on the evidence — about whether the interaction term should be weighted by duration or by intensity.

And it was the best two hours Lyra had had since the hospital, and she understood, sitting on the end of his table with charcoal dust on the side of her hand, that this was the thing she was actually frightened of losing. Not the sight. Her father, at the end of a kitchen table, being interested.

"I would like you to do more of this with me," he said.

"It's not rigorous."

"It is extremely rigorous. It is rigorous in a way I cannot currently check, which is a different and more interesting problem, and I intend to check it." He was writing. He did not look up. "Will you come in on Sunday afternoons? Bring the charcoal. Bring the bad notation. I will bring the coffee and we will be wrong together for two hours."

He still would not say it. She noted that. She let it go. It was a Wednesday, in a kitchen, and he had promised her Sunday.

---

The studio door was at the end of the hall, and it had been shut for five years, and there was no lock on it, and they had never once discussed this.

Lyra went down the corridor at four in the afternoon with the rain still going and stood in front of it and put her hand flat on the wood, which was cool, and which was exactly the temperature of the rest of the house, and which was not, she thought, the temperature of a door and nothing else.

You are being dramatic, she told herself. You are sixteen and you have had no sleep and you have just spent the best morning of your life being argued with by your father, and you want to go and look at your dead mother's things.

She opened it.

The air came out at her like something held. Dust, cold paper, and under it, faintly, linseed oil and the ghost of turpentine, and something else that she had no name for and had smelled perhaps six times in her life, and which was simply her mother in this room.

The easel stood where it had stood. There was a half-finished canvas on it — a hillside, mostly done, the bottom corner still bare primed board — and the bare corner had a clean edge on it, not a torn one, which meant she had put the brush down in the middle of a decision and had never come back.

The desk had a journal on it. Leather, soft, the corners gone white. A circle with radiating lines stamped into the front, blind, no colour.

Lyra did not open the journal.

Not because she had decided not to. She got as far as putting two fingers on the cover, and the room answered.

It was not a sound. It was closer to the way the kitchen felt in the mornings — pressure, warmth, a leaning — except that the leaning had a direction, and it went from the desk to the walls to the ceiling and back down again, and it was silver-blue, and it moved the way water moves in a pipe that is not quite full.

Memory, she thought. Nobody's, specifically. The room's.

She took her hand off the journal and the leaning stayed exactly as it was, patient, and did not follow her, and did not leave.

In the tray on the desk, under four dead brushes, there was a chain with a small silver pendant on it: a circle with lines running out from the centre in a spiral, the same design as the journal's cover, in metal that had gone dull. It was not jade. It was heavier than it looked.

Lyra did not pick it up either.

Instead she stood in the middle of her mother's studio and let herself look, properly, for the first time in five years, and she took in what was actually in the room: a working room, cluttered, warm, used, a chair with a cushion worn flat on one side, a stack of library books with the spines cracked and a receipt from a shop in Chinatown serving as a bookmark, a chipped mug.

Nobody dies in a room like that. That was the thought that arrived, unwanted, and the worst thought she had had all day.

Somebody left in a hurry and was never coming back.

The floorboard in front of the easel creaked.

"Lyra?"

He was in the doorway. He had a towel round his shoulders and his reading glasses in his hand and an expression on his face she could not read in one go.

"Ba, I — "

"How long have you had that door open?"

"Since Tuesday. Since I was five."

The colour went out of his face. He put his hand up onto the frame.

"Then it has been open for five years," he said, "and I have been closing it."

---

He did not shout. Lyra had been braced for shouting and got something much worse: a man standing in a doorway trying to get his breathing under control, and failing, and being visibly ashamed of failing.

"I asked you not to go in there."

"I know."

"Not because I didn't want you to. Do you understand that? I did not close that door to keep something from you. I closed it because I could not — " He stopped. He took his glasses off and pressed the heels of his hands into his eyes, which was a thing he had never once done in front of her. "I could not stand in it."

"But it's just her stuff, Ba."

"Yes," he said. "That is exactly what it is, and that is exactly why I cannot stand in it, and I have not stood in it since the eleventh of September five years ago, and you have just told me you have known about the room for eight years, which means I have been lying to you since you were five, and I need a moment, and I am not going to pretend that I have one."

He went and sat on the bottom stair, which is not a comfortable place to sit, and which he chose.

Lyra stood in the doorway of her mother's studio and looked at the back of her father's head and understood that she had, without any particular wish to do it, taken something from him. Not the room. The not knowing. He had spent five years closing a door so that he would not have to stand in it, and she had, without meaning to, taken away the only reason the door had stayed shut.

"I'm sorry," she said.

"Don't be. Not for that." He did not turn round. "Lyra, I want to be very clear about one thing, because I think you have made an inference and I think the inference is reasonable and I think it is wrong. I did not keep you out of that room to keep you from seeing threads. If I could have stopped you seeing threads I would have done it, and I would have felt like a hero, and I would have been a fool, and I would have lost you into the bargain."

"Then why?"

"Because the people who see what you see end up alone, Lyra. Your mother told me that when we met. She said: the sight is not the problem. The problem is that it puts a pane of glass between you and every other human being on the planet, and you get to watch all of them through it, and nobody gets to watch you." He turned the glasses over in his hands. "And I thought: not her. Not our daughter. Not while I have anything to say about it."

"And yet."

"And yet." He stood up. "And yet she walked into that room on the eleventh of September, five years ago, and told me she had found something, and I told her she was tired, and she went back to the studio and shut the door, and the next morning she was not in it, and the next morning she was not in the house."

The rain had got louder.

"Ba, that's not—"

"I know that is not what happened. I have a whole file on what happened. Police reports, a search that went for eleven months, a lawyer who took our money for two years." He came back up the last two stairs and stopped in front of her. "What I have never been able to explain, Lyra, and what I have never once said out loud in this house, is that I was relieved. That when the police finally stopped coming, and when the neighbours stopped asking, and when we moved from the house on Ellery Street and I put the studio behind me, I was relieved. And I have never forgiven myself for it, and I am telling you tonight because you have been in that room twice now and you are not going to stop, and you deserve to know what you are walking into before you walk into it."

She stood very still. The silver-blue leaning in the room behind her shifted, faintly, the way water shifts.

"What am I walking into?"

"That room, for a start." He almost smiled. "And there is a great deal more than that room, if you want the whole of it. Come out of there. Sit down. I am going to tell you the parts I can bear to say out loud, and then we are going to have an argument about the rest, and then — perhaps, if I can find a way to do it that is not a coward's way — I am going to tell you about the letter that came six days ago."

---

He did tell her about the letter that evening, and it took him an hour and forty minutes, and he got most of it right.

It had come to the university address, because the university address was on file, and it was cream paper with a seal he did not recognise, and it was addressed to Miss Lyra Chen and it said that her abilities — her rare and remarkable perspective, it said — were a gift deserving nurture, and that an institution existed which had been teaching the disciplined use of that gift since 1798, and that it would be visiting her town, and would be glad to speak with her and with her father, and that no obligation of any kind was implied by the receipt of this letter.

"They gave you my name," Lyra said.

"They gave your name, your school, and the date of the last time you were taken off campus for something that looked like a seizure." He said it evenly. "That last detail is the one I would like you to sit with for a moment, because I have been sitting with it for three weeks, and I have not been able to put it down."

Lyra looked at the letter. It was very well made. That was what she kept coming back to. It was the best paper she had ever handled, and the seal was a single line, a thread, passing through an eye, and it had been embossed rather than printed, and somebody had thought about the weight of it in somebody else's hand.

"What did you do with it?"

"I put it in the drawer under the phone bill I did not pay." He was quiet for a second. "I am not proud of that. I want to be accurate: I am not proud of it, and I did it anyway, and the reason I did it is that I could not work out what I wanted to happen, and a man who cannot work out what he wants will do almost anything to postpone finding out."

"Are you going to answer them?"

"I have already answered them. This morning, before you were awake. I telephoned the number on the letter and spoke to a young woman called Eleanor Weaver, who was extremely gracious, and who told me that there would be an informal gathering on Saturday at a bookshop in town, that families were welcome, and that no one would be approached without me present." He turned his cup. "I said we would come. I said it before I had decided to. I would like it on the record that I have been an absolute coward about this for three weeks and that I have now stopped."

Lyra looked at him for a long moment.

"You're not sending me by myself."

"No."

"You're coming."

"I am coming." He almost smiled again. "Lyra, I cannot do the thing you do, and I will never be able to do it, and I have spent two years pretending to believe you about it and I am extremely tired of pretending. But I can sit in a room and be extremely unwelcome and extremely unhelpful, and I can be the person in the corner who is not from their world, and there is a version of this where that is the single most useful thing in the room, and I intend to find out whether there is."

The rain had stopped. Through the window the street smelled wet and green and completely ordinary.

"Ba," Lyra said. "They know my name. They know the date of the thing at school."

"Yes."

"Should we be scared?"

Wei Chen considered this with the seriousness he brought to everything, and Lyra loved him for it, and was frightened alongside him, and the two things sat down next to each other and stayed there.

"I think," he said, "that we should be careful, and not frightened, and that the difference between those two things is going to be the entire subject of the next six months of my life." He got up, and put the letter in his pocket, and stopped in the doorway. "And Lyra. One more thing, and then we are having dinner and I am not discussing it."

"Okay."

"The woman on the telephone. She knew your mother's name."

The kitchen went very cold in a way that had nothing to do with the window.

"She asked about her," Lyra said.

"She asked about her by name, Lyra. Not 'the mother.' Not 'her.' A name." He looked at her for a long moment. "Your mother went to that place. I know that now. I have known it for four years and I have not said it in this house, and I am saying it tonight, and that is the last of it. I am not sure any more what I am protecting. Come and eat."
