It had an extraordinary effect. The color drained out of his face, and his eyes seemed to flash with understanding, and then fear, and then determination. He nodded.
"Don't say anything now," Hannah said quietly. "In a minute I'm going to leave, but I'll forget this book and leave it on my chair. You'll find it and look for me, but I'll be gone. My address is inside the cover. Tomorrow, if you can, bring it to my house in Jericho. And...and the acorn. Can you do that? We can talk there."
He nodded again.
"Tomorrow afternoon," he said. "I can do it then."
He had recovered his color: ruddy, or even lionlike, she thought. She smiled and went back to reading as he gathered up her plate and glass, and then she went through a pantomime of putting on her coat, looking for her purse, leaving a tip, gathering her bag, and going out, leaving her book on the chair pushed under the table.
--
The next day, she could hardly settle to anything. In the morning she fussed with her little garden, pruning this, repotting that, but her mind wasn't on it. Then it started to rain, so she went inside and made some coffee and did what she had never done in her life: tried the newspaper crossword.
"What a stupid exercise," said her daemon after five minutes. "Words belong in contexts, not pegged out like biological specimens."
She threw the paper aside and lit a fire in the little hearth, and then found that she'd forgotten her coffee.
"Why didn't you remind me?" she asked her daemon.
"Because I'd forgotten it too, of course," he said. "Settle down, for goodness' sake."
"I'm trying," she said. "I seem to have forgotten how."
"It's stopped raining. Go and finish pruning the clematis."
"Everything will be drenched."
"Do the ironing."
"There's only one blouse to do."
"Write some letters."
"Don't want to."
"Bake a cake to give that boy a slice of."
"He might come while I'm still making it, and then we'd have to make conversation for an hour and a half till it was ready. Anyway, we've got some biscuits."
"Well, I give up," he said.
At midday, she toasted a cheese sandwich in her mother's blackened old device that hung by the fire. Then she made some more coffee and drank it this time, and then she felt a little more on top of things and managed to read for an hour or so. The rain had started up again.
"He might not come at all if it's pouring like this," she said.
"Yes, he will. He'll be too curious not to."
"You think so?"
"His daemon changed four times while we were speaking to him."
"Hmm," she said, but there was something in what Jesper had observed. Frequent changes of shape in a child's daemon, and a wide variety of forms to assume, were a good indicator of intelligence and curiosity. "And you think..."
"He'll want to know what it means."
"He was frightened. He went pale."
"Only for a moment. Then his color came back, didn't you see? Sort of ruddy."
"Well, we'll know in a few minutes," she said, seeing him at the gate. "Here he comes now."
She stood up even before the door knocker rapped, and put her book down on the little side table before smoothing her skirt and touching her hair. For heaven's sake, what was there to be nervous about? Well, quite a lot, actually. She opened the door.
"You must be soaking wet," she said.
"Well, I am a bit," said the boy, shaking his waterproof coat outside before letting her take it. He looked at the neat carpet, the polished floorboards, and took his shoes off too.
"Come in and get warm," she said. "How did you get here? You didn't walk?"
"In my boat," he said.
"Your boat? Where is it?"
"She's tied up at the boatyard. They let me leave her there. I thought I better bring her up on the bank and turn her upside down, because if she gets full of water, it takes ages to bail her out. She's called La Belle Sauvage."
"Why?"
"That was the name of my uncle's pub. My dad's brother was an innkeeper too, and he had a pub at Richmond and I liked the name."
"Was there a nice sign?"
"Yes, it was a beautiful lady, and she'd done something brave, only I don't know what that was. Oh--here's your book. Sorry it's a bit wet."
They were sitting on either side of the fire, and he was steaming prodigiously.
"Thank you. Perhaps you'd better put it on the hearth."
"It was a good idea to leave it like that so I knew where to come."
"Tradecraft," she said.
"Tradecraft? What's that?"
"A way of...oh, passing messages, that kind of thing. By the way, what's your name?"
"Malcolm Polstead."
"And...the acorn?"
"How did you know to ask me?" he said, not moving.
"There's a way of...There's an instrument....Well, I found out by myself. No one else knows. What can you tell me about the acorn?"
He reached into an inside pocket. Then he held out his hand, and the acorn was resting in his palm.
She took it tentatively, thinking he might snatch it back, but he didn't move. What he did was watch closely as she unscrewed it. Then he nodded.
"I was watching," he said, "to see if you knew which way it unscrewed. It fooled me at first because I never came across anything that unscrewed clockwise. But you knew straightaway, so I reckon this must be for you."
And he brought out the tightly folded sheet of India paper just as the two halves of the acorn fell apart in her hands, showing it to be empty.
"If I'd tried to unscrew it the wrong way...," she said.
"Then I wouldn't have given you the paper."
He handed it to her, and she unfolded it, scanned it quickly, and tucked it in the pocket of her cardigan. Somehow the boy seemed to be in charge, which hadn't been her intention. Now she had to decide what to do about it.
"How did you come across this?" she said.
He told her the whole story, from the moment Asta had spotted the man under the oak tree to the story Mrs. Carpenter in the chandlery had shown him in the Oxford Times.
"My God," she said. She had gone pale. "Robert Luckhurst?"
"Yes, from Magdalen. Did you know him?"
"Slightly. I had no idea he was the one who...We're not supposed to know each other, and I'm certainly not supposed to tell you this. What happened usually was that he'd put the acorn in a dead-letter drop and I'd collect it from there, and then put it back in another place when I'd written a reply. I never knew who put it there or collected it."
"That's a good system," he said.
She wondered if she'd already said more than she should. She hadn't expected to tell him anything, but then she hadn't expected him to know so much.
"Have you told anyone else about this?" she said.
"No. I don't think it's safe."
"Well, you're right." She hesitated. She could thank him and send him away now, or..."Would you like something hot to drink? Some chocolatl?"
"Oh, yes, please," he said.
In the little kitchen she put some milk on to boil and then looked at the message again. Was there anything compromising in it? It was quite clear that the alethiometer was involved, and the identities of the alethiometer specialists in Oxford were no secret. As for Dust, it meant big trouble.
She mixed the cocoa powder with a little sugar and poured in the hot milk, making some for herself as well. The boy knew so much already that she had to trust him. There was little choice.
"You got a lot of books," he said as she came back. "Are you a scholar?"
"Yes, I am. At St. Sophia's."
"Are you an historian?"
"Sort of. A historian of ideas, I suppose. An historian." She switched on the standard lamp beside the fire, and instantly the room became warmer, the weather outside darker and colder. "Malcolm, this message..."
"Yeah? Yes?"
 
; "Have you made a copy of it?"
He blushed. "Yes. But I've hidden it," he said, "under a floorboard in my bedroom. No one knows that space is there."
"Will you do something? Will you burn your copy?"
"Yes. I promise."
His daemon and hers had established a friendship already, it seemed: Jesper was sitting on top of a glass case of ornaments and curiosities, and Asta, in the form of a goldfinch, was perching there too as he quietly explained about the Babylonian seal, the Roman coin, the harlequin.
"Is there anything you want to ask me?" she said.
"Yes. Lots. Who made the acorn?"
"Well, that I don't know. I think they're sort of standard issue."
"What's the instrument? When I asked how you knew it was me that had the acorn, you said there was an instrument. Is that the althee--almeth--"
"The alethiometer...yes."
She explained what it was and how it worked, and he followed closely.
"A-lee-thee-ometer...Is that the only one there is?"
"No. There were six originally. The others are all in other universities. Except one, anyway, which is lost."
"Why don't they make another one? Or lots of them?"
"They don't know how to anymore."
"They could take it apart and look. If they didn't know how to make a clock, and they had one that worked, they could take it apart very carefully and make a drawing of every separate part and how they joined up, and then make more parts like that and make another clock. It'd be complicated, but it wouldn't be hard."
This was all safe. If she could keep him on this subject, she'd have nothing to worry about.
"I think there's more to it than that," she said. "I think parts of it are made of an alloy that can't be made anymore. Perhaps the metal's very rare--I don't know. Anyway, nobody has."
"Oh. That's interesting. I'd like to have a look at it someday. How things fit together--I love looking at that."
"Where do you go to school, Malcolm?"
"Ulvercote Elementary. That's the old name for Wolvercote."
"Where will you go when you leave that school?"
"What school, you mean? I dunno if I will. Prob'ly if I get an apprenticeship...Maybe my dad would like me just to work at the Trout."
"What about going to a senior school?"
"I don't think they've thought of that."
"Would you like to? Do you like school?"
"Yes, I prob'ly would. Yes, I would. But it's not very likely."
His daemon was listening closely. She flew to his shoulder and whispered something, and he very slightly shook his head. Hannah pretended not to see and bent to put a log on the fire.
"What did the message mean by the 'Rusakov field'?" said Malcolm.
"Ah. Well, I don't really know. It's not necessary for me to know everything when I consult the alethiometer. It seems to know what it needs to."
" 'Cause the message said, 'When we try measuring one way, our substance evades it and seems to prefer another, but when we try a different way, we have no more success.' "
"Have you memorized the whole message?"
"I didn't set out to. I've just read it so much, it memorized itself. Anyway, what I was going to say was, that sounds a bit like the uncertainty principle."
She felt as if she was walking downstairs in the dark and had just missed a step.
"How do you know about that?"
"Well, there's lots of scholars come to the Trout, and they tell me things. Like the uncertainty principle, where you can know some things about a particle, but you can't know everything. If you know this thing, you can't know that thing, so you're always going to be uncertain. It sounds like that. And the other thing it says, about Dust. What's Dust?"
Hannah hastily tried to recall what was public knowledge and what was Oakley Street knowledge, and said, "It's a kind of elementary particle that we don't know much about. It's not easy to examine, not just because of what it says in this message, but because the Magisterium...D'you know what I mean by the Magisterium?"
"The sort of chief authority of the Church."
"That's right. Well, they strongly disapprove of any investigations into Dust. They think it's sinful. I don't know why. That's one of the mysteries that we're trying to solve."
"How can knowing something be sinful?"
"A very good question. Do you talk to anyone at school about this sort of thing?"
"Only my friend Robbie. He doesn't say very much, but I know he's interested."
"Not to the teachers?"
"I don't think they'd understand. It's just that being at the Trout, I can talk to all kinds of people."
"Very useful too," Hannah said. An idea was beginning to form in her mind, but she tried to push it away.
"So you think when he mentions Dust, he's talking about elementary particles?" said Malcolm.
"I expect so. But it's not my area, and I don't know for sure."
He stared into the fire for a while. Then he said, "If Mr. Luckhurst was the person who passed the acorn back and forth from you, then..."
"I know. How am I going to contact the--the other people? There's another way. I'll have to use that."
"Who are the other people?"
"I can't tell you because I don't know."
"How was it all set up in the first place?"
"Someone asked me to help."
He sipped his chocolatl and seemed to be considering things deeply.
"And the enemy," he said carefully, "that's the Consistorial Court, isn't it?"
"Well, you've seen enough to realize that, and you've seen how dangerous they are. Promise me you won't do anything else to link you with me or the tree by the canal. Anything dangerous at all."
"I can promise to try," he said, "but if it's secret, I won't know if I'm doing anything dangerous or not."
"Fair enough. And you won't tell anyone what you know already?"
"Yes, I can promise that."
"Well, that's a relief to me."
But all the time the idea kept nagging at her.
"Malcolm," she said, "when those two CCD men came to the Trout and arrested Mr...."
"Mr. Boatwright. But he got away."
"Yes, him. They weren't asking about this sort of thing, were they?"
"No. They asked about a man who came to the Trout a few nights before. With the ex-lord chancellor. A man with a black mustache."
"Yes, I remember you mentioned him. You do mean the ex-lord chancellor of England? Lord Nugent? Not just someone who was nicknamed the lord chancellor, as a joke?"
"Yes, it was Lord Nugent, all right. Dad showed me his picture in the paper later."
"D'you know why the CCD men were asking about him? Was it about a baby?"
Malcolm was taken aback. He'd been on his guard not to say anything about Lyra, as Sister Fenella had advised him; but then the old lady had realized that lots of people knew already, and she'd said that perhaps it didn't matter.
"Er...how d'you know about the baby?" he said.
"Is it something secret? To tell the truth, I heard someone talking about it when I was in the Trout yesterday. Somebody was saying that the nuns...I can't remember exactly, but a baby came into it somehow."
"Well," he said, "seeing as how you've heard of it already..." He told her how it had begun, from the three guests peering through the window of the Terrace Room to his glimpse of the little baby Lyra and her fierce daemon.
"Well, that is interesting," she said.
"You know the law of sanctuary?" he said. " 'Cause Sister Fenella told me about sanctuary, and I wondered if they were going to put the baby there because of that. And she said there were some colleges that could do sanctuary as well."
"I think they all could in the Middle Ages. There's only one that still maintains the right to do that."
"Which one is that?"
"Jordan. And they've used it too, quite recently. Mainly for political reasons these days. Scholars who've upset the
ir governments can claim scholastic sanctuary, like seeking asylum. There's a sort of formula: they have to claim the right to sanctuary in a Latin sentence, which they speak to the Master."
"Which one's Jordan?"
"The one in Turl Street with the very tall spire."
"Oh, I know....D'you think those men could have been asking for sanctuary--for the baby, I mean?"
"I don't know. I really don't know. But it's given me an idea. And I'm going to contradict what I said just now, because I'd like to keep in touch with you, Malcolm, after all. You like reading, don't you?"
"Yeah!" he said.
"Well, let's pretend this: I left my book behind and you brought it back to me--that's perfectly true. You saw all my books, we got talking about books and reading and so on, and I offered to lend you some. To be a sort of library. You could borrow a book or two and bring them back when you've finished and choose some more. That would be a good reason for coming here. Shall we pretend that?"
"Yes," he said at once. His daemon, a squirrel now, sat on his shoulder and clapped her paws together. "And anything I see or hear--"
"That's right. Don't go looking--don't put yourself in any danger at all. But if you do overhear something interesting, you can tell me about it. And when you come here, we'll talk about books anyway. How's that?"
"That's great! It's a brilliant idea."
"Good. Good! Well, we might as well start now. Look, here are my murder mysteries--d'you like that sort of thing?"
"I like all kinds."
"And here are my history books. Some of them might be a bit dull--I don't know. Anyway, the rest are a mixture of all sorts. Take your pick. Why not find one novel and one something else?"
He got up eagerly and scanned the shelves. She watched, sitting back, not wanting to force anything on him. When she was a young girl, an elderly lady in the village where she grew up had done the same for her, and she remembered the delight of choosing for herself, of being allowed to range anywhere on the shelves. There were two or three commercial subscription libraries in Oxford, but no free public library, and Malcolm wouldn't be the only young person whose hunger for books had to go unsatisfied.
So she felt good at seeing him so keen and happy as he moved along, picking out books and looking at them and reading the first page and putting them back before trying another. She saw herself in this curious boy.
At the same time, she felt horribly guilty. She was exploiting him; she was putting him in danger. She was making a spy out of him. That he was brave and intelligent made it no better; he was still so young that he was unconscious of the chocolatl remaining on his top lip. It wasn't something he could volunteer for, though she guessed he would have done so eagerly; she had pressured him, or tempted him. She had more power, and she had done that.
