On the second morning the whole garden was glazed with frost.

It had not been a hard freeze, only the first skin of one, a silver rind laid across every blade and leaf and gravel path. Aveline stood just inside the oak gate with her breath smoking in front of her and her three pairs of gloves tucked into her apron pocket, and she thought that in all her years of fieldwork she had never seen a place that looked so much like it was holding its breath.

"Eight days," said a voice from above her.

She did not jump. She was proud of that. She tipped her head back and found Joren Vael sitting on top of the garden wall, one boot braced against the stones and the other dangling, a heavy mug steaming in his hand. He had shaved. The shadow along his jaw was gone, and without it his face looked younger and a good deal more dangerous, all hard bone and sharp lines. He was watching her the way a hawk watches a field.

"I thought you said you'd keep me in your sight," said Aveline. "I didn't realize that meant from the roof."

"It's a wall."

"It's a height advantage."

"It's the only seat that gives a clear view of the whole garden." He took a swallow from the mug. "Rule one. You are not to enter alone, and I am the escort. I'm escorting."

"From twelve feet away."

"I'm very good at it."

She thought he was, in fact, nearly smiling. It was only a flicker at the corner of his mouth, gone as soon as it came, but she saw it and was annoyed at how much attention she paid it. She turned her back on him and set down her field bag beside the bed.

"Then you won't mind being useful," she said, over her shoulder. "I need a lamp, a spade with a narrow blade, and a bucket of clean water. And someone to hold things."

"I am not a stand."

"No. A stand would be quieter."

There was a silence from the wall. She busied herself with the buckles on her bag and tried not to listen to it. Then, after what felt like a long and highly offended minute, she heard the scrape of boots on stone, the thud of a man dropping lightly to the ground, and the sound of him walking off toward the tool shed with a stride that said, plainly, that he was doing this under protest.

She allowed herself one small, private, entirely unprofessional grin.

* * *

By the time the sun had burned the frost from the paths, she had a system.

She worked from the outside in. First she walked the circumference of the bed, measuring, sketching, noting the angle of the lean in each stem. She took the temperature of the air, the temperature of the soil at three depths, the dampness of the topsoil in four places. She wrote every figure in her notebook in her cramped, upright hand, and when the pages were full she began to write on the back of her left hand, a habit that infuriated her and that she could not break. Joren stood by the bucket and the lamp and the spade and said nothing, and when she asked for the trowel, it was in her palm before she had finished the word.

"You're quick," she remarked.

"I've been doing this a long time."

"With the plant?"

"With the tools." A pause. "It's the same thing."

It was the longest answer he had given her all morning, and she held on to it carefully, like a coin found in a coat.

She spent an hour on the soil. It was extraordinary soil, dark, loose, rich as fruitcake, so clearly cared for that she kept finding herself touching it with a kind of respect. There was nothing wrong with it. No acidity, no salt, no sign of fungus, no trace of the pale threads that marked root rot. She tested it three ways and got the same answer each time, and she sat back on her heels and frowned at the plant.

"It isn't the ground," she said.

"No."

"You knew that."

"I've dug up this bed every autumn for twelve years." He was crouched on the other side of it now, forearms across his knees, the lamp swinging at his boot. "If it were the ground, I would have found it."

"Then why let me look?"

"The Circle insisted."

"That isn't a reason either."

He glanced at her. In the daylight, his eyes were more green than gray, shot through with something paler, and she noticed that when he was tired, which was nearly always, the lids sat heavy over them, giving him a drowsy, brooding air that was a lie. He was the most alert person she had ever met.

"It's a reason," he said. "It's just not the one you want."

She let it go. She had learned to pick her battles in the first hour. She wiped her hands on her apron, reached for the narrow spade, and said, "I'm going to expose the crown."

"Rule two."

"Rule two says I may not touch the plant with bare hands. A spade is not a bare hand." She set the blade against the soil, lifting an eyebrow. "I'm following your law exactly."

A long breath left him. He did not argue. He set the lamp down on the gravel, carefully, as though it were something that might shatter, and said, "Slowly."

She worked slowly. She dug in a half circle, taking out the earth a thumb's depth at a time and laying it on a sheet of canvas. The soil came away easily. It smelled of rain and iron and something sweet and green underneath. The deeper she went, the more silent the garden became, until she realized that the only sounds were the rasp of her spade and the soft drag of Joren's breath, and that he had come around to her side of the bed without her noticing. He was kneeling a foot away, shoulder almost touching hers, holding the lamp low so that its light fell into the hollow she was making.

"There," she said, almost to herself.

At the base of the trunk, where the soil fell away, she saw the crown. It was thick, knotted, ropy with age, dark as an old river root. But it was not one. As she cleared the last of the earth, she saw how the trunk divided just below the surface into two great roots, each as stout as her forearm, springing from a single point and curving away from each other into the dark. One was glossy, plump, firmly rooted, laced with fine white feeders. The other was thinner, paler, nearly threadbare, its fibers dry and brittle as old string.

"Oh," said Aveline.

"What?"

"It has two taproots." She did not look up. She was already sketching, her pencil flying. "I've never seen it. It isn't in any herbal. A single trunk with a split crown, two primary roots of equal origin, one thriving and one starved. It could be a graft, but there's no scar. It could be a congenital malformation, but the symmetry is too exact. It's almost," she hesitated, searching for the word, "deliberate. Like two plants sharing one body."

"It has always been like that."

The words came too fast.

She stopped drawing. She did not turn her head, but she let her eyes move to the edge of the page and held perfectly still, listening. Beside her, Joren was breathing very evenly. It was the careful evenness of a man who has recently remembered to do it.

"Always?" she said.

"As long as I've known it."

"Then you've seen this before."

"I've seen the roots. I didn't know there was a word for them."

It was not quite a lie. She was good at telling the difference. Over the past two days she had learned the particular silences of Joren Vael the way one learns the grammar of an unfamiliar tongue, and this one, she thought, was what he did when he was telling the truth carefully, by leaving out the largest part of it.

She put down her pencil. "May I ask my question for the day?"

"You may ask."

"Is there anything in this garden that would be dangerous for me to know?"

He looked at her then, directly, and it was the clearest look she had ever had from him. Whatever he was about to say, she saw him weigh it, saw him consider and discard three or four answers, saw something raw and tired pass behind his face. When he spoke, it was very low.

"Yes."

She waited. He said nothing more.

"That's all?" said Aveline.

"You said you would rather I refuse than lie." His mouth twisted. "I'm refusing."

It was so unexpected that she felt it in her chest, a small disorienting warmth, the strange sensation of being handed something fragile by a man with very large hands. She turned her face toward the plant before he could see it.

"Thank you," she said.

"Don't."

"All right."

They went on working in silence for some time. It was not an uncomfortable silence. It had a texture, a tension, the way a violin string has tension before it is plucked. She was acutely aware of the warmth of his shoulder four inches from hers. She was aware of the slow dry rasp of his breath. She was aware, with the stubborn clarity of someone who had been careless with her heart once and sworn never to be again, that she was enjoying herself more than she had in months.

*Data,* she told herself. *Symptoms. Nothing else.*

* * *

At noon she proposed the experiment.

She had spent an hour framing it. She did not want to do it. She wanted, very badly, to pretend that the red bud on the first morning had been a trick of light, a thermal flush, an error in observation, and to go on quietly testing soil. But she was a scientist, and a scientist who ignored the one anomaly in the data was no better than the man who had stolen her name. So she wiped her hands, squared her shoulders, and said, "I'd like to repeat the trial from yesterday."

"No."

"Under controlled conditions."

"Rooke."

"If I can't reproduce it, I can't be sure it wasn't coincidence, and if I can't be sure it wasn't coincidence, then I have nothing to put in my report except a guess." She turned to face him. He had risen and was standing a pace away, the lamp hanging from his fist, his face gone still. "And if it is coincidence, Mr. Vael, you can send me home with a clear conscience. I'll go without argument. I'll write the Circle a perfectly polite letter explaining that the plant is beyond saving. Isn't that what you want?"

It was a deliberate move, and she watched it land. She had offered him the thing he had been angling for since the gate: a way out of his own wall. She saw the thought cross his face, saw him actually want it, and saw him know that he wanted it for the wrong reasons. The conflict was so plain she nearly looked away.

"One trial," he said at last. His voice was hoarse. "Four conditions. Then you stop."

"Four."

"Name them."

"Gloved fingers. A glass rod. A bare finger." She hesitated. "And you."

"Me."

"A second subject. If only I can provoke the reaction, it's something about me. If anyone can, it's something about the plant."

He said nothing for a long moment. In the quiet, the garden seemed to listen, and a thin wind came down from the ridge and rattled the dead leaves on the pear trees. Then he set the lamp on the bench with great care and said, so low she barely caught it, "Begin."

She began.

She did it by the book. She drew on her gloves, pale kid leather, supple, thin, and chose a bud from the lowest branch, a different one from yesterday's. She touched it with the pad of one gloved finger, held for the count of thirty, and waited.

Nothing.

She noted the time in her notebook. She took the glass rod from her bag, a slim thing of the type used for testing reactions, and touched it to the bud's tip. Thirty seconds. Nothing.

She heard Joren let out a breath behind her. It might have been relief. She did not turn around.

"Bare finger," she said, and stripped off the right glove.

"Sterilize first."

"I've washed in spirits."

"Again."

She turned and looked at him. He had folded his arms so tightly across his chest that the wool strained over his shoulders. His face was pale beneath the weather. He did not look like a man guarding a prize anymore. He looked like a man standing at the foot of the gallows, waiting for the trap.

"Mr. Vael," she said gently. "What is it you think will happen?"

"Nothing." He swallowed. "Do it."

She wiped her hand with a spirit-soaked cloth that stung her chapped skin, laid it dry on the bud, and held.

For a heartbeat, nothing.

Then the red came.

It came faster this time, and deeper. It rose under her finger like a flush under skin, a warm bright current racing up the stem, spilling into the neighboring buds, climbing into the leaves. All along the lowest branch the hard green knots darkened and swelled, and the brown leaves lifted and unfurled, and the whole limb shivered like a sleeper turning toward the light. Warmth pulsed into her fingers. It was not heat exactly. It was more like being greeted, the soft insistent press of something small and alive against her hand, saying, plainly: *You. There you are.*

She gasped. She could not help it.

And behind her, she heard a sound she would never forget, a low, ragged, wounded breath, as if something inside Joren Vael had split open and he had not been quick enough to catch it.

She pulled her hand back. The color held a moment, a shimmer of crimson across a dozen buds, and then drained away slowly, from the tips inward, as though the plant were reluctant to let go. The leaves sagged. The limb went quiet. She stood trembling in the cold with her finger tingling and her heart slamming against her ribs.

"Reproducible," she whispered. She had to clear her throat to say it again. "That's reproducible. Joren, that's..."

She had said his name. She heard it, a beat too late, and saw by the flicker in his face that he had heard it too. She did not take it back.

"Your turn," she said.

"No."

"The fourth condition."

"You've proved your point."

"I've proved that it responds to me. I haven't proved it doesn't respond to everyone." She stepped aside, offering the bud. "One touch. That's all. It's the only way to exclude a general effect."

He stared at the plant. He did not move. A muscle jumped in his jaw. It occurred to her, as the silence stretched, that this was not reluctance. He knew. Whatever the result was going to be, he had known it before she asked. He was only waiting to watch her find out.

"Joren," she said.

"Fine." The word cracked in half. He unfolded his arms, pulled off his own glove, and held out his bare hand. It was an awful hand to look at, scarred and square and cracked from work. It was shaking, hard. He laid one finger on the bud and held it there as though he were laying it on a coal.

The bud did nothing.

It sat green and hard and small under his fingertip. The branch did not stir. Not a leaf quivered. Nothing flushed, nothing warmed, nothing bent to meet him. It was as if the plant had not noticed him at all.

Joren closed his eyes.

She had seen grief before. She had sat through her grandmother's long dying and her mentor's funeral and the quiet hollowing-out of her own career. She knew its faces, the numb one, the angry one, the one that smiles. She had never seen anything like this. It was as if a man had touched a door he had been told for years was locked, to prove to himself that it still was, and had felt, God help him, the faintest wish that it would open.

He took his hand away. His face was ashen.

"Stop," he said. "The experiment is ended."

"Joren."

"I said stop."

"You were afraid it would respond to you."

"No." He opened his eyes. They were terrible. "I was afraid it wouldn't."

She stared at him. The words fell into the garden like stones into a well, and she waited to hear them land. She did not understand. She understood only that she had been standing at the edge of something very large and very old, and that it had just shifted under her feet.

"I don't understand," said Aveline.

"No." He turned away. "That's rather the point."

"Then explain it to me."

"I can't."

"Can't, or won't?"

"Both." He started toward the wall. "Rooke, we are done for the day."

"You're shaking."

"Leave it."

"You're shaking," she said again, and crossed the gravel in four strides, and caught his wrist.

She did it without thinking. It was the reflex of a physician, a woman trained to take a pulse before she took a history. Her fingers closed around the broad bones of his wrist, over the long old scar, and beneath her thumb she felt the heavy hammering of his blood.

They both went still.

His skin was warm. That was the first thing she knew, and the thing she kept returning to long afterward. His skin was warm, and rough, and alive, and his pulse was racing under her thumb like something trying to get out. She felt the tremor in his tendons, the fine, fierce shake of a man holding himself very tightly together. She heard her own breath stop. She smelled wool and cold air and, faintly, crushed petals, and she knew, with a sudden dizzying certainty, that she had stopped being a physician about three seconds ago.

Joren did not pull away.

He turned his head slowly and looked down at her hand on his wrist, at the ink-stained fingers curled around the old scar, and then up, into her face. He was very close. She could see the dark fan of his lashes, the faint white line of the scar through his brow, the way his pupils had swallowed the green. His mouth was slightly parted. She had no idea what her own face was doing, and was suddenly, horribly sure that it was doing something.

"Rooke," he said. It was barely a voice.

"I'm taking your pulse," said Aveline, with tremendous dignity.

"Yes."

"It's very fast."

"I'm aware."

"You should sit."

"I should." He did not move. "Let go."

"I will."

She did not. For one more breath, one long suspended breath, neither of them moved, and the garden stood around them in the cold white light, silent as a held note. Somewhere in the pear trees, a wren was scolding. Somewhere in the village, a door banged. She felt her heart pounding in her throat and in her ears and in the tips of her fingers, and she knew, as clearly as she had ever known the answer to a problem, that she was in trouble.

She let go.

He stepped back. She thought for an instant that he might say something, anything, that would crack the stillness open. He only flexed his fingers once, slowly, as if testing what had been done to them, and looked at the ground.

She cleared her throat. She needed something to do, and the only thing she could think of was the rule she had made two days ago, the one she had insisted on with such confidence.

"My question," she said. Her voice sounded strange. "For today. I've, I've already used the other one. But I have a second, if you'll allow."

"One a day."

"It's a small one."

He gave a short, tired breath that was almost a laugh. "Go on."

She thought of a hundred things to ask. Why does it answer to me. What are you afraid of. Who did you bury. Who did you lose. She chose none of them. She said, "What did it look like, last spring? When it should have bloomed?"

He lifted his head.

For a moment he seemed not to understand. She saw it reach him by degrees, the plainness of the question, the way it asked for nothing but a memory. The tension in his shoulders eased by perhaps a hair.

"Gray," he said.

"Gray?"

"Every leaf. Every stem. I stood out here for an hour, the morning it should have opened, and it was the color of ash." His voice was low and slow, and he was no longer looking at her but past her, at the thing in the center of the bed. "I thought: if I look away it will be dead when I look back. So I didn't. I stood here until the sun was well up. Nothing changed. Nothing opened." A pause. "That was when I stopped asking it for anything."

It was the most he had ever said to her at one time. She heard the weight of it. She did not make a note. She did not write on her palm. She only nodded, very gently, and said, "Thank you."

"It wasn't a lie."

"I know. I could tell."

He glanced at her sharply, wary, and she met his eyes and did not look away, and she saw something in his face quietly give. It was only a small thing. It was the faintest loosening in the line of his mouth. But it was the first time since the gate that he had looked at her as if she were not a threat.

"Go home, Rooke," he said, not unkindly. "You've done enough for one day."

* * *

She did not go home. She went to the little room above the baker's, where the Circle had lodged her, and sat on the edge of the narrow bed and stared at the wall for an hour. Then, because she could not sit still, she lit the lamp and spread her notebook across the quilt and began to copy out her findings.

It helped. It always did. There was a clean, cold comfort in turning a day into columns.

*Soil: normal. No pathogen in samples taken. Temperature: normal for season.*

*Reaction to touch, subject A (Rooke), bare skin: positive, reproducible. Gloved: negative. Instrument: negative.*

*Subject B (Vael), bare skin: negative.*

She frowned at that last line and drew a small box around it. Then, slowly, she added underneath: *Subject B anticipated negative result. Subject B appeared distressed by it.* She did not know what to make of that. She underlined it twice.

At the bottom of the page she drew the roots. She drew them as she had seen them in the pale morning light, the thick glossy one and the pale starved one, springing from a single crown. She worked on it for a long time, shading the grain of the bark, the white feeding threads, the dry and brittle fibers of the lesser root. When she was done she sat back and looked at it.

*Not a disease,* she thought.

She had not expected the thought. It arrived whole and quiet and certain, the way her best ideas always did. The plant was not sick. Sickness had patterns, spread and progression, vectors and symptoms. This had the look of something else. It looked like a body that had been *given less than it needed*. One root fed, one root starved. A plant that was not dying of disease but of neglect, of a long, patient, deliberate withholding.

Or of waiting.

*It's waiting for something,* she wrote, and frowned at her own handwriting, because it was not a scientific sentence, and she did not write unscientific sentences. She crossed it out. She wrote it again underneath.

Outside her window the rain had begun, a soft steady drizzle that pattered on the slates. She was reaching to snuff the lamp when someone knocked at the door.

It was Pip.

He stood on the narrow landing with water dripping off his straw-colored hair and a bundle held tight against his chest, eyes enormous, looking as though he had run the whole way. He shoved the bundle at her without a word.

"The warden said to bring it," he whispered. "He said, you left this at the garden, and it'd be spoiled."

She took it. It was her canvas field bag, and tied about it, tight and careful, was a square of oilcloth, knotted twice. Inside, the notebook she had left on the garden bench was dry. Every page. He had wrapped it against the rain.

"He said you'd be wanting it tonight," Pip added. "He said not to tell you he said so."

"Pip."

"I'm not telling." The boy was already backing toward the stairs. "I never said nothing. Nobody asked me." He hesitated at the top step. Then, in a rush, with all the mortal gravity of eleven years old, he said, "He doesn't do things like that. For people. I thought you ought to know."

He fled.

Aveline stood in the doorway with the notebook in her hands and rain whispering on the roof. She looked at the oilcloth and the neat double knot and thought about a man with scarred hands who had stood in a garden in the dusk and decided, against every instinct he had, to keep a stranger's pages dry.

She sat for a long time without moving. She did not write anything down.

* * *

In the morning she was at the gate at first light, two hours before she was due, because she could not sleep and could not think of a better place to be.

The frost was thicker. Every twig of the pear trees was sheathed in white. The air was so cold that it hurt to breathe, and the sky over the ridge was the pale gold of new honey. The lodge door stood shut. No smoke rose from its chimney. The warden, it seemed, was elsewhere.

She went in alone, which was against the rules. She did not touch anything. She only walked to the bed and stood looking down at the plant, the dark old trunk and the bent stems, the pale heap of fallen petals that no one had yet raked away.

She had not meant to look at the lowest branch. She did anyway.

On it, where she had touched the buds the day before, there were three. Small and tight and dark, no bigger than the end of her thumb. They had been green yesterday. Now each one wore a thin rim of crimson along the seam of its sheath, a hair's width of red, like a line drawn with a fine pen.

One of them had opened a little. Only a very little. A hint of velvet showed in the gap between the sheaths, deep and dark as a coal in ash.

Aveline stood perfectly still.

She did not touch it. She did not breathe on it. She only looked, with her heart beating slowly and heavily in her chest, and a small cold voice at the back of her mind reminded her that she was a rational woman and that this was a rational problem and that there was nothing in the least frightening about a flower.

*It's waiting,* she thought.

And then, because there was no one to hear her and the garden was so very quiet, she said it aloud, softly, to the dark old plant and the bright new buds and the pale morning sky:

"For what?"

The wind moved through the pear trees. The petals on the ground lifted, all together, in a single small shimmer of red, and settled again.

The bud did not answer. But it did not close.
