The path to Briar Glen had not been a path in any proper sense for a hundred years. It was a suggestion cut into the hillside by goat hooves and the slow insistence of running water, a thread of pale stone threaded between walls of blackthorn and elder that leaned inward like mourners at a grave. Kestrel Vane followed it on foot, his boots finding purchase where the moss allowed, his left hand occasionally bracing against the rough bark of an elder when the slope grew treacherous. The afternoon was bleeding toward dusk, and the light through the canopy had gone the color of weak tea, shifting and uncertain.
The scar on his forearm burned.
It had been burning since dawn, a slow throb that matched his pulse and made the muscles of his hand clench without his permission. He had unwrapped it once, at a stream crossing, and the sight had turned his mouth dry. The black lines had spread another quarter inch past the bandage he had bound at Greyford. They branched now, thin capillaries of something that was not infection and not rot but some third thing, something that moved beneath his skin like a living root seeking water.
He wrapped it again, tighter, and kept walking.
The smell of the glen reached him before he saw the cottage. Woodsmoke, yes, but also something greener and stranger beneath it. Sage, maybe. The particular tang of yarrow that had been steeped too long. He had not been here in three years, not since the night he had crawled out of the mud at Wren's Hollow with a spear wound in his thigh and the dead piled high enough to serve as ramparts. Sable Orren had pulled the broken shaft out with a pair of iron tongs and muttered something over the wound that smelled of honey and char. He had not stayed to thank her properly. He had not stayed anywhere properly for very long.
The cottage came into view through a screen of hawthorn, low and stone-floored, with a roof of moss and a chimney that leaked smoke from a crack near its base. A goat regarded him from a pen of stacked turf, its yellow eyes flat and unimpressed. Two chickens scratched at the dirt near the door, and a cat, orange and half-starved, watched him from a windowsill with the particular disdain reserved for armed men who arrived uninvited.
He stopped at the edge of the clearing and waited. The scar pulsed. He did not knock.
A long moment passed. A door creaked somewhere out of sight, and a voice came from the left side of the cottage, near a woodpile.
"You smell like road dust and bad decisions."
The woman who emerged from behind the cottage was shorter than he remembered, though perhaps he had been more badly hurt than memory allowed, because everything had seemed larger that night. Sable Orren had a face like a weathered apple, all creases and angles, and eyes the color of river stones. Her hair was iron-gray and bound in a knot at the nape of her neck with a strip of leather. She wore a man's coat over a wool shift, and her boots were caked with the same mud as the path, as though she had been checking traps or gathering something from the lower woods.
Kestrel inclined his head. "Ma'am."
"Don't ma'am me. I heard you a quarter mile back. You walk like a man with a wound he's trying to forget about." She set down the wicker basket on her hip, and something inside it shifted with a dry rustle. Herbs, then, or mushrooms. "I also heard you stopped at the stream and unwrapped something and then wrapped it again, and I heard you hold your breath when you did it, which means it hurt. So. Which is it. The leg, or something new?"
"New."
Her mouth flattened into a line that held no sympathy but no cruelty either, only the grim practicality of a woman who had seen enough wounds to be bored by them. She jerked her chin toward the door. "Inside. I'll brew something. You'll tell me what happened, and you'll tell me the truth, because I have not got the patience or the years left to be lied to."
Kestrel followed her through the low doorway, ducking beneath the lintel. The interior was dim and close, the air thick with the smell of dried bundles hanging from the rafters. Bundles of lavender. Bundles of something darker, the leaves almost black in the shadows. A fire burned low in a hearth of rough stone, and a kettle sat in the embers, already beginning to whisper. Sable moved to it with the economy of long habit, lifting the lid, dropping in a measure of something from a jar on the shelf above.
"Sit. Anywhere that isn't my bed."
He sat on a three-legged stool near the fire, the wood creaking under his weight. The heat touched his face, and he realized how cold he had been without noticing. The scar throbbed in time with his heart, a slow insistent rhythm that made his teeth want to set on edge.
"Coat off. Sleeve up."
He did not argue. He undid the laces of his jerkin, the stiff leather resisting his fingers, and pushed the left sleeve of his shirt up to the elbow. The bandage was a strip of linen gone gray with travel, wrapped tight and stained at the center with a discoloration that was not quite blood and not quite ink. Sable set down her iron spoon and crossed the small room, moving a lamp closer with her other hand.
"Set your arm on the table. Palm up. Don't move."
Her fingers were cool and dry, surprisingly gentle, as she unwound the bandage. The scar was a thing of branching darkness, a tree of black lines radiating outward from a central knot the size of a thumbnail, the original wound where the thing had bitten him. It was not a bite mark now. It was a mouth.
Sable's breath caught, a small involuntary sound she smothered almost at once. She did not pull her hand away. She leaned closer, the lamp held steady, and studied the branching lines with an expression Kestrel could not quite read. Not fear, exactly. Something colder.
"When," she said.
"Nine nights ago. A village called Marrowfield, east of the Greyve."
"East of the Greyve is not a place I know well, but I know the sound of it. What's left of it?"
"Ash. The Hollow Ones came through in the night. The wards had fallen. They took what they wanted and burned what they didn't." He paused, watching her face. "I killed the one that did this. Or I thought I did. It went down, and the teeth stayed in, and when I pulled them out the bleeding wouldn't stop. Someone in the village packed the wound with cobweb and a poultice. It closed, but the black came a day later."
"Cobweb and poultice." Sable straightened, and the lines of her face seemed to have deepened. She set the lamp down with a careful precision, as though it might shatter if she did not handle it as if it were glass. "That bought you a week. Maybe a little less, the way it's moving. I have heard of this, lad, but I have not seen it in twenty years, and I had hoped to go another twenty without seeing it again."
Kestrel did not ask what it was. He already knew, in the way a man knows a thing that has been whispering at the edge of his sleep for nine nights. He asked the only question that mattered.
"Can you stop it?"
Sable moved back to the hearth and stood for a long moment with her back to him, the firelight catching the silver in her hair. When she spoke, her voice had a weight to it that had not been there before.
"I can slow it. I can give you time, if time is what you need to finish what you started in that village. But I will not lie to you and say I can cut it out. It has grown past the wound into the muscle. It has put down roots. I would have to take the arm to take all of it, and even then, I would be guessing whether I had got the last of it."
The fire crackled. The cat from the windowsill had followed them inside and now sat in the doorway, its green eyes fixed on Kestrel's arm.
"How much time," he said.
"Weeks. Perhaps a month. Longer if you rest and let me dress it twice a day with what I have. Shorter if you ride hard, or fight, or spend any more time near whatever touched you in the first place." She turned, then, and fixed him with a look that had the quality of a held blade. "Where is the thing that bit you? Truly. Not where you found it. Where is it now."
"Dead. I am almost certain."
"You are almost certain." She repeated it flatly, the way one repeats a child's foolish promise. "Almost certain will kill you quicker than the wound, Kestrel Vane. Sit there. Do not touch the arm. Do not scratch it, no matter how it itches. I am going to brew something that tastes like boiled boot leather and regret, and you are going to drink it, and then you are going to tell me everything you remember about the night those wards fell."
Kestrel did not move. The scar throbbed, and in the corner of his vision the cat's eyes glowed, and somewhere outside the goat gave a short, mournful complaint at the gathering dark.
Maren's back was to him as she worked at the low table, grinding something in a stone mortar. The sound was rhythmic, a rasp and a scrape, and beneath it the fire muttered in its own slow language. The cottage smelled of dried rosemary and something sharper, an astringent bite that stung the inside of his nose.
Kestrel looked down at his arm. The scar had not changed. It never did, not in any way he could see. But he could feel it, a slow pulse out of time with his heartbeat, and the skin around it had gone the color of old tallow.
"You are grinding your teeth," Maren said, without turning.
"I am not."
"You are. I can hear it from here. Stop. You will crack a tooth and then I will have to pull it and you will be sorry."
He unclenched his jaw. The cat in the doorway had begun to wash itself with one precise paw, its ears flat in concentration. Outside, a shutter banged once and was still.
The cottage was small and close. A single room with a sleeping loft above, the ladder up to it so narrow it looked as though it had been built for a child or a careful witch. Bundles of dried herbs hung from the beams, and jars of murky liquid lined a single shelf. There was a chair, the one he sat in, and a stool by the fire, and a table scarred with knife marks and ring stains. A second door stood shut at the back, and through it he could hear the soft industrious scratch of the goat arranging itself for the night.
Maren finished grinding, tipped the powder into a clay cup, and poured hot water over it from a kettle that sat always by the hearth. Steam rose, thin and bitter. She brought it to him.
"Drink."
He drank. It tasted exactly as she had promised, of leather and regret, with an undertone of something green and medicinal that made the back of his throat close up. He finished it anyway because she was watching and because she would only ask again.
"Good. Now. The wards. Tell me."
So he told her. He told her about the night the villagers had come to him at the inn, the old woman with the missing fingers and the man who could not stop shaking. He told her about the road to the hamlet, the wet smell of it, the way the trees had leaned inward over the path as though listening. He told her about the circle of pale stones and the smell of rot and the way the air had tasted of iron when he had stepped across the threshold.
He did not tell her about the thing that had come out of the dark. He found he could not, not yet, not in this small room with its herbs and its fire. Some things lost their power when spoken aloud, and some things gained it, and he was not yet sure which the memory would be.
Maren listened without moving. When he had finished, she sat back on her stool and folded her hands in her lap.
"You crossed a working ward," she said. "A binding, of some kind. The villagers had built it to keep something out, or perhaps to keep something in. You broke it when you crossed the threshold. Whatever was caged behind it walked free because of you."
"I know."
"Do you. Because you walked in there knowing the wards were down, knowing the smell of rot was coming from inside the circle, and you walked in anyway. Why."
"Because someone had to."
"That is not an answer. That is a habit."
He looked at her then, and she held his gaze. Her eyes were the pale gray of river water in winter, and there was nothing soft in them at the moment, nothing of the girl who had pressed her hand to his arm in the road and flinched away from the cold of it. She was, in this moment, entirely the apprentice of a hedge witch who had learned to read hurts as other people read books.
"The scar you carry," she said. "I have seen its like before. Once. In a book my mistress kept locked in a chest by her bed, because she did not want me to read it and because she knew I would. It is called the Demon Kiss. It is a mark, and it is also a hunger. The flesh around it will keep spreading, and as it spreads it will change you. Your eye will go first, I think, and then your hand, and then your mind. By the end you will not be able to tell the difference between yourself and the thing that bit you. You will hunt as it hunted. You will feed as it fed."
The fire popped. The cat stopped washing and sat very still.
"How long," Kestrel said.
"I told you. Weeks. A month, if you are careful."
"And if I am not careful."
"Then less. Much less. There is a plant that will check it. Moonpetal. It grows only in one place that I know of, and that place is the Sunless Reach, which is three days' ride from here through country I would not cross alone, and which is also, by every account I have ever heard, the hunting ground of something that should not be named."
"Say its name."
"I will not. You will hear it soon enough, if you go. Everything in the Reach knows its name, and it does not like strangers using it."
Kestrel looked down at his arm. The scar throbbed, once, in time with his heart this time, and the skin around it twitched as though something underneath had turned over in its sleep.
"Then I will go," he said.
"You will not go tonight. You will sleep here, in front of this fire, and in the morning I will give you a salve and a packet of the powder I just made you drink, and you will ride south to the Sunless Reach with my blessing and my very clear opinion that you are a fool."
"Your blessing."
"Yes. And my opinion. They are not the same thing, but I am giving you both."
He almost smiled. It surprised him. He had not thought he had any smiles left in him, not after the village, not after the ward, not after the dark.
"Why," he said. "Why do this. You do not know me."
"I know what the Demon Kiss looks like. I know what it does. I know that no one deserves it, not even a stubborn sellsword who walks into obvious traps because someone has to. You will let me dress the wound again before you sleep, and you will not argue with me about it."
"I was not going to argue."
"Good. Then we understand each other."
She rose and crossed to the shelf, and took down a jar of pale green paste and a strip of clean linen. She brought them to him and sat on the stool at his feet, and unwrapped the bandage with fingers that were quick and sure and did not shake at all. The scar was worse in the firelight, the gray creeping farther up his forearm, the edges of it puckered and wrong. She looked at it for a long moment without speaking.
Then she began to work.
The paste was cold and it stung, but the sting was clean, the sting of medicine and not of rot. She spread it with a wooden spatula and then wound the linen around his arm with a competence that made him think of old soldiers and field surgeries. When she had finished, she tied the bandage off and sat back.
"Tomorrow," she said. "Now sleep. I will wake you before dawn."
She rose and crossed to the back door, and opened it, and the goat complained once more in the soft dark of the byre beyond. She spoke to it quietly, in a voice he could not quite hear, and the goat was silent. Then she came back, and banked the fire with a careful hand, and climbed the narrow ladder to the loft, and he was alone with the embers and the cat.
The cat looked at him from the doorway. Its eyes were very green.
"I do not need a staring contest," he said.
The cat did not blink.
He laid his head back against the chair and closed his eyes. The scar pulsed. Somewhere outside, very far away, a fox screamed, the sound rising and falling like a question that would never be answered. The cottage settled around him, the beams creaking, the herbs stirring in some draft he could not feel.
He did not think he would sleep. He had not slept properly since the village, not more than an hour at a time, and every time he closed his eyes he saw the pale stones and the dark behind them and the shape that had come out of the dark with a hunger older than the trees.
But sleep came, all the same. It came like a hand on his brow, cool and uninvited, and he slipped into it without a sound.
In the loft above, Maren lay awake and listened to his breathing slow and deepen. The goat dozed in the byre. The cat in the doorway purred once, softly, and then was still.
Outside, the night turned toward morning, and the road to the Sunless Reach waited, patient as a held breath.
Maren woke before the dawn, as she always did, to the smell of wet thatch and the small complaints of the goat. For a moment she lay still, listening. The loft boards above her head were cold. Below, the chair where Kestrel had slept sat empty, dragged close to the dead hearth, and the cat was winding between its legs, mewing with theatrical impatience.
She climbed down, her bare feet finding the rungs by memory. The cottage was dim and smelt of ash and cold herbs. Kestrel stood by the window, his back to her, the locket in his palm. The dawn was a thin grey line at the edge of the moor, and in that line, very small and far away, she thought she could see a shape moving.
"You're up early," she said.
"I don't sleep well." He did not turn. The locket caught what little light there was and threw it back, a small sharp point that moved as his hand moved. "There's someone out there."
She crossed to the window and stood beside him. For a moment they were very still, two figures in a grey room, breathing the same air. Then she saw it too, and her hand went to the locket at her own throat before she could stop it.
The figure was a woman. She walked the way the wind moves across open ground, without hurry, and even at that distance there was something in her carriage that made Maren want to step back from the glass. She wore dark clothes, and her hair was bound back, and she carried something long across her shoulders, a staff or a bundle, Maren could not tell which.
"The witch," Kestrel said quietly.
"Yes."
They watched her come. The moor was wide and grey, and the heather bent under her feet, and the small sound of the door latch, when Maren unbarred it, seemed to travel a long way across that emptiness.
Sable Orren stopped three paces from the threshold. She was older than Maren had expected, though how old it was hard to say. Her face was weathered to the color of old wood, and her eyes were the pale grey of rain on stone, and she looked at them both with a patience that was not quite human.
"You kept me waiting," she said.
"We slept," Kestrel said. "My apologies for the inconvenience."
The corner of her mouth moved. It might have been a smile. It might have been something else.
She looked at Maren, then, and her gaze lingered on the locket, and something in her face shifted, a recognition of a thing she had been looking for. Maren felt the small weight of it against her collarbone grow suddenly heavier, as if it had been waiting to be seen.
"May I come in?" Sable said. "The morning is not kind, and I have a long walk yet."
They stepped aside. The cat fled under the settle. The goat complained once, and Sable looked toward the byre with an expression that might have been fondness, and went to the hearth, and stood there as if waiting for a fire that was not there.
Maren knelt and rebuilt it from the embers, coaxing them with dried bark and the breath of her cheeks. The flames came up, orange and small, and threw their shadows long across the floor.
Sable watched her work.
"The locket," Sable said. "It is the one from the pale stones."
Kestrel stiffened. Maren did not look up.
"It was my mother's," Maren said. "She wore it the day they came."
"And now you wear it."
"Yes."
Sable was quiet for a long time. The fire crackled. The cat crept out from under the settle and sat at a safe distance, watching.
"I can hear it," Sable said, at last. "From here. From the road. I have been hearing it since yesterday, a small sound, like a bee in a jar. It is louder when you are near."
Maren's hands stilled on the kindling.
"What does it say?" Kestrel asked.
"Nothing. It hums. That is all. But the hum is not like other hums, and I have lived long enough to know the difference."
She unslung the long bundle from her shoulders, and leaned it against the settle, and Maren saw that it was a staff, dark wood, polished by long use, with a small cage of iron at one end in which something glowed a dull and sullen red.
"What are you?" Maren asked.
"A woman of the moor," Sable said. "And a keeper of old roads. And now, if you will have me, a guide for a little way into a place I have walked before and would rather not walk again."
Kestrel sat down across from her. The chair creaked under him.
"The passage through the Sunless Reach," he said. "The road through the hollow."
"Yes."
"You know it."
"I know the first part of it. The parts the maps do not show. The parts that shift." She looked at the fire, and her face was unreadable. "I will take you as far as the Standing Stones, and no farther. The Stones are the last place I have any right to be."
"And in exchange?" Kestrel said.
Sable looked at him, and there was a small hardness in her gaze that Maren did not like.
"A favor," Sable said. "Unnamed. For a time of my choosing."
The fire popped. A log settled. The cat stretched and resettled, one paw over its nose.
Kestrel looked at Maren. She looked back. The locket hummed against her throat, a sound so small she was not sure she had truly heard it, but Sable's eyes moved to it at once, as if she had.
"We accept," Maren said.
"Maren," Kestrel said.
"We accept," she said again, and her voice was steady, and she did not know where the steadiness came from. "If you can take us through the first part of the passage, we will owe you a favor. Unnamed. For a time of your choosing."
Sable inclined her head. The deal was made. The fire crackled, and the morning came up grey and wide over the moor, and somewhere far to the east the road to the Sunless Reach waited, patient as a held breath.
Sable rose. "Eat," she said. "Then we walk."
They ate what there was: hard bread and a little cheese and water from the jug. The cat watched them from the doorway. The goat watched from the byre. The locket hummed against Maren's throat, and once, when she touched it, she felt the small bones of her mother's fingers still resting there, cold and patient.
Kestrel ate little. He had not eaten much since the village. Sable noticed, and said nothing, and when they were done she rose and took her staff, and stood in the doorway looking out at the morning.
"There is a path," she said. "You will not see it. You will not see most of what I show you. Walk where I walk. Step where I step. Do not speak unless I speak first. Do not answer anything you hear in the dark. Do not look back."
She looked at Maren.
"Especially you," she said. "You wear a thing that has a memory, and the Reach will want it, and if you look back it will have you."
"I understand," Maren said.
"Do you?"
"Yes."
Sable studied her for a long moment. Then she nodded, once, and stepped out into the grey, and the small sound of her staff on the threshold was the first step on a road they could not come back from.
They followed.
The moor took them. The heather closed behind them as they walked, and within a few hundred paces the cottage was gone, swallowed by the grey, and there was only the path under their feet and the wide sky above and the small figure of Sable Orren moving ahead of them with a sureness that did not belong to any country Maren had ever known.
Kestrel walked at her shoulder. Maren walked behind, and the locket hummed, and the hum grew as they walked, a small steady note that rose in her chest like a bird in a room. She did not look back. She did not look back. She kept her eyes on Sable's staff, on the small dull glow in its cage, and on Kestrel's shoulders ahead of her, and on the path that was not a path at all but a long grey line across an emptiness that had no name.
The Sunless Reach waited. And the road went on, patient as a held breath.
