By the fifth night the room had begun to feel like something the two of them shared, and Shuohan resented it.

He could not say exactly when it had happened. The red wedding robe still lay folded against the wall, where it had become, without discussion, his. The blue quilt had gone back to the bed on the second night and returned to the floor on the third, and neither of them had mentioned it. A small brass kettle had appeared on the hearth. A second cushion had been dragged closer to the table. On the wall above the lacquered chest hung the cord of wooden peaches, four beads gone white and ninety-six still red, and every dawn, when the candles folded themselves out and another bead paled, he caught himself looking up at it with something that was not quite satisfaction.

It was a habit, he told himself. A man grew used to anything. Even a prison acquired a shape.

The weather had been turning since noon. He had felt it first in Hanxue, a restless, ticking chill along the steel, and then in the air itself, which had gone thin and metallic and smelled of iron. By sunset the sky over the boundary road was the color of a bruise. Gu Chiyan, bringing in the supper tray, had paused on the threshold with his head tilted and said, "Wind tonight. It will come down off the north ridge. I would keep the shutters latched," and then, with his usual bright smile, "But of course you will. You are both so very careful."

He had gone away humming. Shuohan had not liked the humming.

Now the first hours of the night were gone, and the candles stood in their brass holders burning straight and gold, and the wind had arrived. It did not howl. It pressed. It leaned against the walls of the lodge with a long, patient weight, like a great animal settling its shoulder against a door, and every so often it found some small seam in the stone and slid through it with a thin, high whistle that raised the hair on his arms.

The blades lay bare on a low wooden stand beside the table, as the fourth clause required, Hanxue and Taoying side by side with their points turned slightly toward one another. Neither of them hummed tonight. They were quiet, the way a cat is quiet when it is listening.

Yunzhao sat cross-legged on the bed with a book open on his knee. He had been on the same page for an hour. Shuohan knew because he had not once heard it turn.

"It is only wind," Yunzhao said, without looking up.

"I did not speak."

"You are listening so hard the room has gone tense. I can feel it in my teeth." He turned a page at last, with great ceremony, as if to prove a point. "Chiyan said to latch the shutters. We latched the shutters. The lodge has stood for three hundred years. Be easy."

"I am easy."

"You are sitting like a man waiting to be shot."

Shuohan looked at his own hands. He was, he realized, sitting exactly as he would have sat at the head of a line in a duel, straight-spined, thumb on the cord of his sleeve. He made himself unclench.

Two more nights, he thought, to the seventh. Chiyan had said that was the one on which the bond was hardest to hold. He did not know why the thought had come to him now, or why it came with a small cold prickle of dread. It was not the seventh night. It was only the fifth. It was only wind.

The flames shivered.

* * *

It was the smallest thing. A flicker, no more. Both flames bowed together, a hair's breadth to the left, and straightened again, and for a moment he thought he had imagined it.

Then the wind changed.

He felt it before he heard it. A thin knife of cold slid across the back of his neck from somewhere to his right, from the door, from the floor, from a seam in the world that had not been there a moment before, and every nerve in his body went white. The flames leaned. They did not bow this time. They bent, both of them, slowly and steadily, like grass under a hand, until the golden tips streamed sideways and the light in the room went wild.

He was on his feet without having decided to rise.

So was Yunzhao. The book hit the floor. They both lunged for the table at the same instant, from opposite sides of the room, with the same single thought driving them, and the room was small and the table was smaller and they met in the middle with a collision that rattled the brass.

A shoulder in his chest. A hip against his thigh. A hand, somewhere, closing hard on his wrist. A sharp bright breath of laughter that was not a laugh at all.

"Move," said Yunzhao.

"You move."

"The left one, look at the left one..."

He looked. The candle on the left, the one on Yunzhao's side of the table, had shrunk to a bead of blue no bigger than a lentil. It clung to the wick, shuddering, and as he watched the wind came again and flattened it almost to nothing.

The second clause. They shall not be snuffed, shielded, or relit by any other. He could not shout for Chiyan. He could not call a servant. If they wanted the flame, they would have to keep it with their own hands, and now, not in a moment.

He did not think. He raised his right arm and spread the wide red sleeve of his under-robe across the front of the candle like a wall, and at the very same moment Yunzhao, with a muttered curse, did the same from the other side. Silk met silk. White and red overlapped. Their forearms crossed in the air above the flame, and the two sleeves joined into a single curtain, and beneath it, in the small bright cave they made, the blue thread of the candle stopped shuddering, and held.

Neither of them moved.

It was very quiet under the sleeve. The wind roared on outside the curtain, and in here there was only the faint whisper of the flame and the sound of two people breathing hard. Shuohan became aware of several things in succession, each one a little sharper than the last.

That he was standing very close. That the table pressed into his thigh and Yunzhao's chest was an inch from his own, so close that every breath the man drew lifted the white silk against Shuohan's sleeve. That there was warmth coming off him in a steady wave, like a banked fire. That a strand of dark hair had come loose across Yunzhao's cheek, and that it moved a little each time he exhaled.

That Yunzhao's hand, where it crossed his under the curtain, was trembling, and that his own was not.

"Do not," said Yunzhao, very low.

"I have said nothing."

"You were about to tell me we are touching."

"We are not touching. The sleeves are touching."

"The sleeves have a great deal of me in them."

"It is necessity," said Shuohan. His own voice sounded odd to him, rough and a little low. "The terms allow necessity."

"I know the terms. I helped write them." The whisper had an edge of unsteady laughter in it. "Is this the kind of necessity you meant?"

"It is."

"Good. I would hate to be accused of a violation."

The flame brightened a little under their joined sleeves. It stood up, thin and gold, and swayed in a quieter rhythm. Beside it the other candle, the one on Shuohan's side, gave a dip, and a thread of smoke curled from the wick.

"The other," he said.

Yunzhao's eyes went to it, and widened. "I cannot reach. If I let go of this one..."

"Hold it."

"Shuohan..."

"I have it."

He stretched his left hand across the front of his own candle and cupped it, palm curved and fingers spread, and the cold of his skin met the heat of the flame and the frost on his hand began to melt, hissing faintly. It hurt. He did not care. The two of them stood in the middle of the room, leaning over the table with their arms bent around two flames like a pair of men carrying a bowl of water over a rough floor, and in the unsteady glow their faces were very near.

And the swords woke.

They did it together, without a sound. Hanxue first, a long pale shimmer of frost rushing along the steel until the blade glittered like a river under moonlight. Taoying a breath after, a soft rose-colored flush, then a spill of petals that rose into the air in a slow spiral and turned silver in the flame. The two lights met above the stand and wound about one another, ice and blossom, white and rose, and fell across the faces of the two men in a shifting, trembling glow.

He saw Yunzhao's eyes then, quite clearly, a bright, startled, uncomplicated brown. There was frost in the lashes. There was no smile.

They stared at one another over the candle.

It lasted perhaps three heartbeats. In that time Shuohan thought nothing at all. He had a vague, helpless awareness of the swords singing at his back, and of the pulse in his wrist, and of the odd fact that he could smell the other man, cedar smoke and peach and warm cloth, in the middle of a gale. Then the draft came again, a hard, sideways slap, and the flames lurched, and the spell broke like a dropped plate.

"The window," Shuohan said.

"The door," said Yunzhao, at the same moment.

They looked at each other.

"Both," said Shuohan.

* * *

Afterward he could not have said who gave the orders. There were none, really. There was a long, strange minute in which two men who had spent five days being scrupulously careful with each other moved around a small room like parts of the same machine.

He let go of the flame and Yunzhao took it, and the left candle did not so much as flinch. He crossed to the window in three strides, snatched the heavy Hanjian cloak from its peg and shook it out, a great spreading sheet of blue wool lined with fleece. The lattice shutter had come loose at one corner, its latch lifted a finger's width, and the wind was feeding through the gap in a long cold stream. He jammed the cloak into the frame, folded it twice, pushed a fold hard into the corner, and pinned the whole mass in place with the iron poker from the hearth, wedged across the lattice like a bar.

"Left side," Yunzhao called, softly, from behind him. "You have missed a hand's breadth."

He did not argue. He tucked in the left edge. The whistle stopped.

He turned in time to see Yunzhao do something he had not expected. The man had left the candle in the care of a ring of his own cupped fingers, one-handed, and with the other hand he had dragged the quilt off the bed and was on his knees at the base of the door, stuffing it into the gap between the boards and the floor. He worked with a quick, practiced economy, twisting the cloth into a roll, pushing it into the crack with the flat of his hand, and he was muttering under his breath the whole time, a low cheerful stream of insults directed at the quilt, the door, the wind, and the architect of the lodge.

"A hundred nights," he was saying, "a hundred, in a house built by a man who hated doors..."

"The upper edge."

"I know, I know." He stuffed the cushion in above the quilt. "There. Is it holding?"

Shuohan stood and listened. The wind outside went on, huge and patient and entirely without effect. In the room, nothing moved. The air hung heavy and still. And on the table, in the new quiet, the two flames drew themselves up to their full height, straight and golden, as calm as two monks at prayer.

"It is holding," he said.

Yunzhao let out a long breath. He sat back on his heels, one hand pressed flat against his ribs, hair in his eyes, sleeves rucked up to the elbow, and looked at the candles. Then he looked at the cloak jammed in the window, and the quilt rolled along the floor, and the iron poker slanting across the lattice like a drunken sentry, and he began to laugh.

It started low, a dry little hiccup in his chest, and grew. He put the back of his wrist against his mouth and it did not help. He laughed until his shoulders shook and his eyes ran and he had to lean against the door, and the sound was so bright and foolish and unguarded that for a moment Shuohan simply stood in the middle of the floor and listened to it, as to a bird singing in the wrong season.

"I am sorry," Yunzhao gasped. "I am so sorry. It is only that you looked so... You put a poker through the window. You said 'left side' like a general. I have never in my life been given an order by a man holding a fire iron."

"It was effective."

"It was magnificent." He wiped his eyes. "We have kept the flame alive with a quilt and a cushion and your coat. If Qingyun could see us. If Hanjian could. The Ice Swordsman and the Draft."

He waited for the sting of it. He had been waiting for it all week, the bright quick jab of that tongue, and Shuohan had developed a good many defenses. He found, standing there with frost still melting on his palm and the swords fading slowly from white to quiet, that he did not need any of them. He was not mocked. It was not a laugh at him. It was only a laugh, the kind a man gives when he has been very frightened and finds himself, to his own surprise, safe.

"It was a good quilt," he said.

Yunzhao stared at him. Then he laughed again, harder, and slid down the door until he was sitting on the floor with his knees drawn up, helpless, and Shuohan, who had not intended any joke at all, felt a strange crooked sensation tug at one corner of his mouth.

He turned away before it could finish.

He went to the table and stood looking at the candles, because it was easier than looking at the man on the floor. The flames were calm now. The frost had retreated from the planks. Hanxue and Taoying lay quiet on their stand, their edges still faintly lit, and between them, on the polished wood, lay a few pale petals and a delicate skin of melting rime, as though a spring and a winter had met there and called a truce.

He had looked at that smile for too long.

He understood it suddenly, and with a cold start. It was not the laughter he had been listening to. It was the face. The open, crumpled, wet-eyed delight of it, the way it altered every line of the man's features and made him look ten years younger and not at all like a person who had ever learned to hide. He had watched it for the length of a full minute, with his hand slack on the table and his thoughts entirely gone. He had not been guarding anything. He had not been counting the steps to a door.

He had simply looked.

His ears began, absurdly, to burn.

"Ling Shuohan?" said Yunzhao, behind him, still faintly breathless. "Are you all right? You have gone quiet."

"I am thinking."

"About what?"

"The wind."

It was a very poor lie. He heard it die in the air. But Yunzhao, to his surprise, did not press. There was a pause, and then a quiet, amused "Ah," and the sound of cloth shifting, and when Shuohan risked a glance back over his shoulder he found the man still sitting on the floor with his head tipped against the door, studying him with an odd soft attention, the way one studies a bird that has landed on a sill.

"Thank you," said Yunzhao. "For the cloak."

"It was necessity."

"Of course." The smile that touched his mouth was small and tired and, as far as Shuohan could tell, entirely genuine. "Necessity. I am going to start saying that about everything."

* * *

He did not go back to the cushion at once.

There was a stiffness in the air, and a languor in his limbs, and he wanted something to do with his hands. He crossed to the hearth and put another handful of coal on the fire. He straightened the poker. He picked up the book Yunzhao had dropped, found the place by the ribbon, and set it on the bed without looking at the title. All the while he felt the other man's eyes following him around the room, light and unhurried.

Behind him, Yunzhao said, in a voice that was almost idle, "It is odd."

"What?"

"The draft." There was a rustle as he got to his feet. "Chiyan warned us of the wind. We latched everything. I checked the lattice myself this afternoon, and the shutter was tight as a drum. It does not seem likely that a latch which held for three days would lift itself in a single gust."

Shuohan turned.

Yunzhao was not looking at him. He had come to the door, and gone down on one knee again beside the quilt, and he was running his fingers slowly along the frame. His face had lost all its laughter. It was intent and narrow, and the lamplight cut deep shadows beneath his cheekbones.

"Come here," he said. "Bring the candle. No. Not that one. The lamp."

He brought the little oil lamp from the mantel. Yunzhao took it without a word and held it close to the wood, at the latch side of the frame, where the door met the plaster.

The boards there were old, dark, and smooth with a century of hands. But along the edge, in a line about the length of a man's forearm, the grain was torn. Pale splinters stood up from the wood like fur. Beneath them lay a long, narrow groove, bright and raw and fresh, with the sticky gleam of sap still faintly in it. The plaster beside it had crumbled in a small white drift.

Shuohan crouched. He put out one finger and touched the groove, and it was sharp, and it came away dusted with new sawdust.

"Pried," he said.

"From the outside." Yunzhao's voice was very soft. "With a thin blade. Someone slid it into the seam and worked the frame away from the wall, a finger's width, no more. Enough to let in a draft. Not enough to be seen from the inside unless you were looking for it." He turned his head. In the light of the lamp his eyes were black. "A man who wanted the wind to do his work for him."

Neither of them spoke.

Outside, the gale dropped, quite suddenly, as if a hand had been laid over its mouth, and the lodge fell into a silence so complete that Shuohan could hear the candles burning on the table behind him. Two small steady whispers. Two tiny, patient hearts.

The fifth night. The last of the wind was running out across the dark hills, and with it, he thought, went the last of the idea that they had been safe.

Someone had stood beneath their window on the night of the rite. Someone had come back, with a knife, to open a door.

"The seventh night," he said, and was surprised by how calm it sounded. "Chiyan said the bond is hardest to hold."

"Yes."

"He did not say it would be made harder."

Yunzhao set the lamp down on the floor between them. In its small yellow light the new groove shone like a wound.

"No," he said. "He did not."
