The water hit Maren Voss at mid-thigh, black and sharp with cold, tasting of iron and old stone. She sucked air through her teeth and pressed her shoulder against the curved wall of the aqueduct. Above her, a handspan of air remained between the waterline and the arched ceiling. The tunnel stretched ahead into a darkness that swallowed the feeble light from the grate behind them.
"Hold," she whispered.
The word passed down the line like a stone dropped into still water. Behind her, the Nightmarrows, fourteen of what remained of Sergeant Hulsten's loyal guard, ceased their shuffling. Their breathing filled the tunnel, ragged and too loud. Maren counted heartbeats. Seven. Eight. The scrape of steel on stone where one of them shifted his weight.
"Maren." Talia Brenner's voice, barely louder than the lap of water against Maren's hip. Warm even at a whisper, with the soft rise of a Welsh lilt. "Movement ahead. Thirty yards, maybe forty."
Maren did not turn. Her hand rose, fingers spread, then closed into a fist. Hold position. She strained her ears past the water, past the breathing, past the small anxious sounds men make when they know death waits at the end of a long throat of stone.
She heard it. The clink of a buckle. The low murmur of a voice giving an order she could not quite catch. Rendyll's forward scouts, the ones Talia had spotted an hour before on the ridge. They had come down into the aqueduct to make their stand.
"How many?" Maren asked, her voice so low it barely stirred the air.
"Four I counted. Could be more in the dark." Talia's bow creaked as she adjusted her grip. "They're blocking the junction. We go through, we go through them."
Maren closed her eyes for half a breath. Four. Maybe more. Fourteen of hers, armed with swords and short spears, soaked to the bone and cold already numbing their fingers. Four of the enemy, dry-shod on the raised walkway that ran along the aqueduct's eastern wall, where the original builders had left a ledge for maintenance. A killing ground, if the scouts were smart enough to use it.
She opened her eyes. "Hulsten."
The old sergeant moved up beside her, his bulk cutting the already thin air. He smelled of wet wool and the leather of a belt worn for thirty years. Water pooled in the creases of his scarred face. He did not speak. He waited. His eyes, pale and steady in the gloom, found hers.
"They hold the walkway," Maren said. "We cross thirty yards of open water. No cover."
Hulsten considered. His jaw worked once, twice. "Aye."
"The walkway is stone. A foot and a half wide. They stand above us. We stand below."
"Aye." The word came out harder. "What are ye asking me, lass?"
Maren let the silence answer. She watched his face, the way the muscle along his scar tightened, the way his hand drifted to the sword at his side but did not close. He understood. She saw it in the way his shoulders dropped half an inch, the way his breath left him in a single slow push through his nose.
"Push through," Hulsten said. "Straight at them. No stopping, no parley. Drive them back or die trying."
"We lose men."
"We lose more if we wait. Talia's lass spotted them on the ridge. They'll have runners. By dawn, Rendyll will have a hundred soldiers in this tunnel, and we'll be rats in a pipe." He met her gaze. "I'd rather be a rat that bites."
Maren nodded once. She turned to the line behind her, her hand finding the shoulder of the nearest soldier, a boy named Cael who had not yet seen twenty winters and whose teeth chattered so loud she could feel it through his jerkin.
"Listen," she said, pitching her voice to carry just far enough. "Thirty yards ahead, the enemy holds the walkway. We go through them. Single file along the wall, then fan out when we reach the junction. Talia takes the first with an arrow. The rest of you, keep your heads down until you're under them, then bring them down into the water. Steel does not rust so fast that we cannot open a throat with it."
Silence answered. Then a ripple of motion, hands checking belts, swords drawn with soft hisses.
"Hulsten takes the front," Maren continued. "I take the rear. Anyone who falls, we leave. Anyone who panics, I will put them down myself. Do you understand?"
"Aye, Captain," came the murmur, not quite in unison, not quite a whisper.
Maren had not been a captain. She had been a conscript, then a deserter, then a refugee, then a woman with nothing left to lose. The title had found her the way a stray dog finds a beggar. She did not correct them. There was no time for the truth, and the truth would not keep them alive.
They moved.
The water resisted every step. Maren felt it climb her thighs, her hips, the cold settling into the bones of her pelvis like fingers of ice. The sound of fourteen bodies pushing through the flooded tunnel filled the space, a sloshing, splashing, obscene noise that would carry. She had ordered silence, but silence was a dream in moving water. The only mercy was that the enemy would have to guess their numbers.
Talia slipped past her, moving with an ease Maren envied. The scout's slight frame cut the water like a blade, barely a ripple, the longbow held high above her head. She had notched an arrow already. Maren could see the fletching tremble with Talia's controlled breathing.
"Ready?" Talia asked, her mouth close to Maren's ear.
"Ready."
Talia surged ahead, vanishing into the dark. Maren watched the line stretch out behind her, the bobbing helmets, the pale faces. Hulsten's bulk at the front, his broad back a wall of sodden wool. The boy Cael third in line, his jaw clenched against the chattering. A man named Dren, a farmer turned soldier, who had killed three men at Greenmoor and wept after each one. Behind him, the others, fourteen names she had learned and would try to forget.
The enemy voices grew louder. A laugh, low and private. The clatter of dice on stone. They were playing. They were bored. Maren's teeth showed in the dark, a grimace that was not quite a smile.
Then Talia's bow sang.
The arrow's flight was a whisper she could not hear, only imagine, a thin shadow through the black. A strangled grunt, wet and final. One of the dice clattered off the walkway and splashed into the water.
Hulsten roared. The sound filled the aqueduct, a beast's bellow, and he surged forward with his sword high. The Nightmarrows followed, screaming, the fear in their voices transmuted into something louder and more useful.
Maren could not see the fight. She could only hear it. The ring of steel on steel. A splash. A scream cut short. Another splash. Hulsten's voice, barking orders that no one could obey in the chaos. Then a cry that was not a battle cry, but the high, keening wail of a man who had just understood he was about to die.
"Panic," Talia's voice came from somewhere ahead, clipped and flat. "He ran back into the line."
Maren pushed forward. The cold had climbed to her chest. Her legs burned with the effort of moving through the water, each step a small war against the weight. She reached the knot of struggling bodies just as a soldier broke from the melee, scrambling backward along the wall, his eyes wide and white in the dark.
"No, no, no," he was saying, the words tumbling out in a panicked stream. "They've got more, they've got more, there are dozens, I saw, I saw them all, I cannot, I cannot, I cannot, I cannot, no, no, no, no, no, no, no..."
He slammed into Maren, his hands grasping at her shoulders, his face a mask of animal terror. She smelled the sickness on his breath, the sour tang of a man whose body had already surrendered. His name was Pyr. She remembered him from the night before, when he had shared his rations with a younger boy and told a poor joke about a goat.
"Pyr," she said, gripping his wrists. "Pyr, look at me. Look at me."
He would not look. His eyes rolled, searching for an exit that did not exist. His hands clawed at her, desperate, pleading. Behind him, the fight still raged, steel singing, men grunting, water churning red.
"Pyr."
He screamed and shoved her. She stumbled, caught herself on the wall. When she turned back, he was thrashing in the water, making no progress, his sword forgotten, his body bent on retreat.
The tunnel was too narrow for fear.
Maren watched him flounder. She gave him three heartbeats. Four. Five. He made no move to fight, only to flee, and his flight was a danger that would spread like fire through dry brush. One panicking man became two, became five, became a rout, and a rout in this tunnel meant death for every one of them, crushed against the walls, drowned in three feet of black water.
She drew her short sword. The blade was cold, heavier than it had any right to be. Pyr had his back to her, still scrabbling at the wall, still sobbing. He did not hear her approach. He did not feel the press of steel until it was through him, sliding between the ribs at the back, finding the soft architecture of the lung. He made a sound, small and surprised, like a child woken from a dream. His legs stopped kicking. His hands loosened. He turned, just enough, and Maren saw the moment he understood. His mouth formed a word. She did not catch it. He sagged, and the water took his weight, and he floated for a moment before the current caught him and pressed him against the wall of the aqueduct.
Maren stood over him, the sword dripping. Her arm trembled. She did not know if it was the cold or what she had just done, and she decided not to find out.
"Forward," she said, her voice cutting through the noise. "Forward, all of you. Now."
The line surged past her. She let them go, every one, keeping her place at the rear as she had promised. Bodies splashed through the water, grunting, cursing. The last of them, a one-eyed veteran named Tosk, paused beside her, his gaze dropping to Pyr's body.
"Panic," Tosk said. Not a question.
"Panic," Maren confirmed.
Tosk nodded once, as if she had confirmed the weather. He moved on.
Maren turned back to Pyr. The current had already begun its work, pressing the corpse into a narrow gap where the aqueduct wall met a supporting buttress. The body would not pass. It was too broad across the shoulders, and the water would not compress what the gods had shaped. In minutes, Pyr would be wedged there, his face turned toward the dark they had come from, his open eyes seeing nothing, a message written in blood and cold for anyone who came after.
She touched his shoulder. Just once. A small pressure, a goodbye, an apology.
"Forgive me," she whispered.
She did not know if he heard. She did not know if the dead could. She turned and waded after her soldiers, the water closing over the space where she had stood, and the tunnel ahead of her filled with the sounds of men trying to kill each other in the dark.
The cistern district of Greenmoor opened before them like a cathedral of stone and rust.
Maren tasted iron as she climbed from the aqueduct's throat onto the broad brick walkway that ringed the first of the great settling tanks. The taste had nothing to do with the blade in her grip. It came from the cold, from the mineral breath of the water, from the city itself, which seemed to bleed in every season but this one. Her teeth ached with it. Her gums ached. She had been told once, by a field surgeon in the southern camps, that the taste meant the air was too thin, that the body was being cheated of something it needed. She had never learned what.
She filed the question away and moved.
The walkway curved away from her into a gloom that the pitch-soaked torches set into iron brackets did little to relieve. She could hear the water before she could see it, the low perpetual churn of the cistern's surface somewhere below the walkway's edge, a sound like a man trying to clear his throat and failing. When she did see it, she saw only a shifting darkness, the faintest suggestion of movement, and the dull sheen where the moonlight fell through a perforated grate set high in the vaulted ceiling above. The grate cast no real light. It cast a memory of light, the suggestion that somewhere a moon still lived.
She counted bodies in the gloom. Talia, crouched against the far curve of the walkway, her bow already half-drawn, her eyes on the grating. Three of the rear guard, pressed flat against the brick, breathing through their teeth. The rest of the line strung out behind her, eight of them in all, plus herself, plus the two scouts who had gone ahead and not yet returned.
"Maren."
Talia's voice was barely a breath. Maren crossed to her in four quick strides, keeping low, her boots finding the dry bricks between the puddles of condensation. The water-keepers, whoever they were, had laid reed mats in those puddles. The small civility of it, somewhere in the back of Maren's mind, insisted on being noticed.
"The grate," Talia murmured. "Count."
Maren looked up. She counted. Six shadows moved against the far lattice, black on black, their outlines broken by the iron bars. They were not moving quickly. They were moving with the patient deliberation of men who had been told to watch and had been told well.
"How long?" Maren breathed.
"Since we surfaced. They're not patrols. They're sentries. Static posts. They've been posted since before we came through."
"Posted by whom?"
Talia's mouth thinned. "The same hands that posted the men in the aqueduct, I should think. The same payroll. The same iron in the same purse."
Maren considered the long curve of the walkway, the open expanse of the settling tank below, the narrow iron stair that descended to the maintenance deck where the sluice gates were cranked by hand. If the sentries above the grate saw them, the grate would be reported, and the report would find its way upward through whatever chain of hands ruled Greenmoor's garrison tonight. They could not allow the report.
"And the scouts?"
"Kell said he smelled lamp oil. Grease. A forge, somewhere below. The water-keepers keep a smithy in the lower tier, for the pump fittings."
"A smithy at this hour."
"With a fire in it."
Maren nodded slowly. A smithy meant men working, men whose hands were occupied, men whose attention would be fixed on hot iron and on the ringing of their own anvils. They would be loud. They would not hear footfalls on stone.
"How many in the smithy?"
"Kell did not say. But the chimney is drawing. The smoke is heavy. They have been working a while."
"Working what?"
Talia turned her face toward Maren. The torchlight caught the edge of her jaw, the line of her scar, the white of one eye.
"Fittings," Talia said. "For the great gate at the river end. The one that holds the city water back when the river rises."
Maren understood. The great gate was the heart of the cistern's function. If the gate failed in a flood, half of Greenmoor's lower wards drowned in a night. If the gate failed by design, half of Greenmoor's lower wards drowned on purpose. The smithy was not a smithy. It was a workshop. The water-keepers were not water-keepers. They were men paid to know which bolts to tighten and which to leave loose, and on whose signal the loosening should occur.
"Kell," Maren said quietly. "And the other."
"Went down to look."
"Alone?"
"Kell does not like company. You know this."
"I know this."
Maren considered the line behind her. Eight men, plus herself, plus two who had gone ahead. Of the eight, she trusted four absolutely. The other four she trusted only because they had nowhere else to go.
"Form on me," she said, low enough that only the nearest could hear. "Single file. Talia, you take the point. Three paces to my front. The rest of you, breathing space. No one speaks. No one runs. We go down to the maintenance deck, we find Kell, we find whoever has him, and we put them down before they put word up the chain. Questions."
No one asked.
Talia rose in a single fluid motion and moved to the point. Maren watched her settle into the rhythm she had been born to, each step a thought, each pause a sentence. The line behind Maren shuffled into its order without sound. Good men. Mostly good men. One of them, the youngest, was breathing too quickly. Maren reached back without turning and laid her hand briefly on his shoulder. He slowed. She felt his gratitude in the way the muscle relaxed.
She took her hand back and gave the signal.
They moved.
The stair down to the maintenance deck was narrower than the walkway and twice as steep. It descended in a tight spiral along the inside of the cistern's outer wall, the iron of its railings cold even through her glove. The sound of the water grew louder as they descended, then louder still, until it was no longer a sound but a presence, a thing one could lean against. The air thickened with it, grew heavier, took on a smell like wet iron and old stone and the faintest thread of lamp oil. Maren tasted the oil at the back of her throat. So Kell had been right about something, at least.
Talia, three paces ahead, raised one hand. Fist closed. The line stopped.
From somewhere below and to their left, beneath the spiral of the stair, came a sound that Maren had not heard in a long time and had hoped never to hear again. It was the sound of a man being persuaded, professionally and at length, to give up what he knew. It was not loud. It was patient. It went on between one breath and the next, methodical as a clock.
Talia's hand opened. Two fingers extended, pointing down and left. Maren leaned past the inner curve of the rail and looked.
Below them, on a small stone platform lit by a single shielded lamp, two men knelt with their hands bound behind them. A third man stood over them. He was not large, but he was patient, and in his right hand he held a short iron pry, the kind used for drawing nails. He was speaking. The kneeling men were listening. The kneeling men were trying very hard not to scream.
Between the kneeling men and the interrogator, his back against the stone wall, his face turned toward the stair, sat Kell. Kell's hands were unbound. Kell's face was not marked. Kell was looking up at Maren with the expression of a man who had been waiting for some time and was grateful, in a tired way, that the wait had ended.
Maren held up one finger to Talia. Wait.
She mouthed a question.
Talia mouthed an answer. Four. Four more, beyond the lamp. Working.
Maren nodded. She unslung the short sword from across her back and held it at her side. She pointed to herself, then to Talia, then down. Talia nodded. She drew the long knife from her belt, the one with the hooked tip, and held it low against her thigh.
Maren turned to the line behind her. She held up four fingers. She made a spreading gesture. She pointed to two of the older soldiers, then to two of the younger ones, and mimed a half-circle. They understood. They would come at the smithy from the gallery on the far side of the maintenance deck, where the forge stood, and they would do so when they heard the first sound from below. Not before.
Two of them peeled off without a word. The rest held their places.
Maren began to descend. Talia, three paces ahead of her, began to descend as well. The spiral of the stair put the interrogator's lamp into view, then out of it, then into it again. Each time, the scene below was unchanged. The kneeling men still knelt. The interrogator still spoke. Kell still sat. The patience of the scene was obscene.
At the bottom of the stair, the platform widened into a short corridor that ran toward the forge. The corridor was unlit except for the spill from the lamp on the platform. The air here was warmer, and heavier, and it smelled of hot iron and of the resinous smoke from a smith's fire. Somewhere ahead, the ring of an anvil answered the ring of a hammer, slow and methodical, the rhythm of men who had been told to keep working and had obeyed.
Talia slipped past Maren without a sound. She went low along the wall, the long knife held out in front of her, the hooked edge toward the platform. Maren went high along the opposite side, the short sword held back over her shoulder, ready for a downward cut. They converged on the platform from opposite sides. The interrogator, still speaking, still patient, still holding his iron pry in his right hand, did not see them until Talia was already inside the reach of his arm.
Talia did not waste the reach. She took his wrist first, turning it inward, taking the pry from him in the same motion that brought the long knife up under his jaw. The pry clattered once against the stone and went still. The interrogator made a small sound, more surprise than pain, and then no sound at all. Talia lowered him to the ground with the care of a woman laying a child in a bed, which was, Maren thought, exactly the wrong thing to think at such a moment.
Kell had not moved. His eyes were on Maren now. He was holding something in his lap, beneath a fold of his coat. Maren did not ask what it was. She crossed the platform in three strides and crouched beside him.
"Report," she said, very low.
"Four at the forge," Kell said. "Working the great gate. They have loosened the lower bracket. They mean to let it go on a signal. The signal is a green flare from the roof of the garrison. The flare is timed for dawn."
"Dawn."
"Less than three hours."
Maren nodded. She looked at the two kneeling men, whose faces she now recognized. One of them was young, no older than the youngest of her own line. The other was older, his beard grey, his eyes fixed on some middle distance that Maren could not see.
"Who are they?"
"Smiths," Kell said. "Conscripted. The older one tried to refuse. The younger one tried to run. They have been here since last night. They have not eaten. The interrogator was beginning to ask them who had told them what to do."
Maren looked at Kell. Kell looked back. Neither of them said the name that was in both their mouths.
"Can they walk?"
"Barely."
"Can they work?"
"The older one can. The younger one, I am not sure."
Maren stood. She pointed to one of the soldiers behind her, the oldest, the one called Greff, who had been a farrier before the war had made him something else. She pointed to the older of the kneeling smiths. Greff understood. He went to the man and began to cut his bonds.
Maren turned to Kell. "What did you bring down?"
Kell lifted the fold of fabric. Beneath it was a sheaf of papers, written in a hand she did not recognize, on paper she did recognize. The watermark in the corner was the seal of the garrison's quartermaster.
"What are they?"
"Instructions," Kell said. "For the gate. For the timing. For the green flare. And for what comes after the gate is opened."
"What comes after?"
Kell looked at her for a long moment. The light from the forge, somewhere ahead, flickered on the edge of his face.
"A second order," he said. "For the cistern's overflow channels. To be opened at the same moment the gate fails. The channels run beneath the lower wards. If both are opened at once, the lower wards will not simply flood. They will be scoured."
Maren looked at him for a long time. She heard the anvil ahead. She heard the water behind her. She heard the breathing of the men in the corridor, and the small, tired sounds of Greff cutting the bonds of a man who had tried to do the right thing and been punished for it.
"The green flare," Maren said. "Where is it kept?"
"The garrison roof."
"The garrison roof is outside the cistern."
"Yes."
Maren nodded. She looked at Talia, who was wiping her long knife on the hem of the interrogator's coat.
"Talia," Maren said. "How good is your eye at night?"
"Good enough," Talia said, without looking up.
"Good enough for what?"
Talia looked up. She looked at Maren for a long moment. Then she smiled, and the smile was not a kind one.
"Good enough for a roof," she said.
Maren nodded once. She turned to Kell.
"Get these men out," she said. "Get them to the lower gallery. Get them behind the line. When the four at the forge hear us come, they will try to run. Do not let them run. They know too much. They know the timing. They know the channels. They cannot be allowed to reach the chain."
Kell stood. He gathered the papers into the fold of his coat and held them against his chest. He bowed once, briefly, to Maren, and then to the older smith, and then he and Greff and the smith disappeared into the corridor, the smith leaning on Greff's shoulder, his feet barely finding the ground.
Maren turned to the rest of her line. Four of them, plus herself, plus Talia. Five of them against four at the forge.
She did not like the arithmetic. She did not like any of the arithmetic that night. But she had learned, in the long arithmetic of the war, that the numbers one liked and the numbers one survived were rarely the same numbers, and that the only arithmetic that mattered was the one written in the bodies of the men who had tried to write a different sum and had been corrected.
She signalled. They went.
The aqueduct swallowed them.
Maren moved first, her boots finding the slick stones with the instinct of a woman who had walked too many dark corridors in the dark of too many bad nights. The water ran at her right, black and quick, its surface catching the single pale bar of moonlight that fell through the gap in the roof far ahead. The air was wet, tasted of iron and old moss, smelled faintly of the forge they were approaching and, beneath that, the sharper tang of hot metal being worked by someone who did not want to be heard working it.
Talia came second, her long knife held low and angled across her body, her eyes already adjusting to the dark. Behind Talia came the other three, spread in a thin line, their shoulders brushing the curved wall, their breath held or released in careful, slow measures. No one spoke. The only sounds were the water, the drip of condensation from the roof, and the distant, muffled clang of the smith who did not yet know they were coming.
Maren counted her steps. She had learned, in the long arithmetic of the war, that the last twenty paces before contact were the longest. Her hand rested on the hilt of her sword, and the hilt was cold, and her fingers were cold, and the cold was a familiar thing, an old companion, the temperature of the grave she had been promised by every man who had ever tried to take her life and had failed.
She rounded the last bend and saw the forge.
Four men. Two at the anvil, one feeding the fire, one watching the approach to the upper galleries. The watcher was young, slighter than the others, and he was the first to see her, and the first to die, because Talia's long knife took him in the throat before the sound of her boot on the wet stone had faded.
Maren did not see the kill. She heard the wet sound of it, and then she was among the others, her sword out, the bright line of it catching the forge-light as it came down across the nearer smith's sword-arm just above the elbow. The man screamed, a high, thin sound that bounced off the curved walls and came back to her as a chorus, and his sword clattered into the water and was gone.
The second smith came at her with a hammer. She parried it on the flat, felt the shock of it travel up her arm and into her shoulder, and stepped inside his guard and drove the pommel of her sword into his temple. He dropped like a cut rope and did not move again.
The man at the fire turned to run. One of her line, a wiry man with a soldier's quick hands, caught him by the collar and threw him against the wall, and the man struck his head and sat down heavily in the shallow water and began to weep.
It was over in twenty heartbeats.
Maren stood in the forge-light, her sword dripping, her breath coming in slow, controlled draws. She looked at the bodies in the water and at the man slumped against the wall and at the smith with the ruined arm, who was on his knees now, clutching the joint, his face gone the grey of old ash.
"Hold him," she said, and one of her line moved to the kneeling man and pulled his hands behind his back and bound them with a strip of cloth torn from his own coat.
She turned to the man by the wall. He was older than the others, his beard greying, his eyes wide and wet, and when he looked at her she saw something in them that was not fear. It was recognition.
"Maren Voss," he said, and his voice cracked on the name. "I was at Thornfield. I saw what you did at Thornfield."
Maren looked at him. She did not lower her sword.
"What is your name," she said.
"Brenner," the man said. "Edric Brenner. I am her father."
The forge-light wavered. The water at Maren's feet ran on, indifferent. Somewhere above them, in the city that did not yet know what had happened in its guts, a bell rang twice for the half-hour, and the sound came down through the gap in the roof and lay on the stone like a fallen leaf.
"Bring him," Maren said, and her voice was steady, and she did not look at Talia.
They brought him.
Talia had not spoken since the kill at the throat. She walked behind her father now, her long knife still in her hand, her face a mask of the careful blankness she had learned to wear when something inside her was breaking and she did not intend to let anyone see the cracks. She did not look at him. She did not need to look at him. She knew the shape of his shoulders, the way he favored his left leg, the particular rhythm of his breath when he was afraid.
Maren led them up out of the aqueduct and through the lower gallery and into the small stone room that Kell had used for the interrogation. She had Greff bring a lamp. She had the smith with the ruined arm set on a bench against the wall and bound, and the weeping man set beside him, and she had Edric Brenner set in the single chair in the middle of the floor, under the lamp, where the light would find every line of his face.
She stood across from him. She did not sit. There was no other chair.
"Tell me," she said. "Tell me what you were forging."
Edric looked up at her. He looked, she thought, like a man who had been running for a long time and had only just now realized that the ground beneath his feet was solid and that he could not, in fact, keep running.
"The chain," he said. "The chain for the western gate. Lord Rendyll commissioned it three months ago. We were told it was for a monument. We were told it was for a public work. We were not told what it was truly for until a fortnight past, when the man with the black coat came and gave us the timing and the channels."
"The channels," Maren said.
"The aqueducts," Edric said. "The old aqueducts beneath the walls. They run from the forge-pool to the foundations of the western tower. The chain was to be drawn through them, link by link, over the course of a night. We were to be the smiths. We were to be paid in silver and given our freedom when the work was done. We were told the silver was honest. We were told the freedom would last."
He looked at Talia, and for the first time something moved in his face that was not fear.
"She does not know," he said. "I did not tell her. I did not want her to know what I had become."
Maren did not look at Talia. She kept her eyes on Edric.
"The channels," she said again. "You knew the timing. You knew the route. You knew the night."
"Yes," Edric said.
"You knew," Maren said, "that if the chain went through, the western gate would fall, and the queen would be cut off from the loyal regiments beyond the river, and the city would be given to Rendyll in a single night."
"Yes," Edric said, and his voice broke on the word.
Maren looked at the lamp. The flame moved in some imperceptible draft, and the shadows on the wall shifted, and the room seemed to breathe.
"Sergeant Hulsten," she said, without turning. "Enter."
The sergeant entered. He moved to the side of the room and stood with his back to the wall and his hands clasped in front of him. He did not look at Edric. He looked at Maren, and his face was the careful, weathered blank of a man who had seen this moment before and did not enjoy it and had long ago stopped pretending to.
"By the laws of war," Maren said, "this man is a traitor. He has knowingly worked on a device intended to betray a royal city to a sworn enemy of the crown. The penalty is death, carried out before the dawn, in the presence of witnesses."
She paused. The lamp flame steadied.
"Under the old laws," she said, "and under the new laws of the Iron Queen, which have not yet been written, and which will be written in part by what I do in this room in the next sixty seconds, the man who commits treason forfeits his life and the protection of his name. His children forfeit their standing. His wife, if he has one, is stripped of her dower. His house is razed."
She looked at Edric.
"You knew this," she said.
"I knew it," Edric said.
Maren looked at Talia.
"You knew this about him," she said. "You have always known what kind of man your father was. You have known it, and you have loved him anyway, and you have hated him anyway, and you have done both of these things in equal measure, and you have never once, in all the years I have known you, let either one of them make you soft."
Talia did not speak. Her jaw was set. Her eyes were wet, but she did not blink.
"I am going to ask you a question," Maren said, "and I want you to answer it as the soldier you are, not as the daughter."
Talia nodded once.
"What would you have me do," Maren said.
The room waited. The lamp waited. The water beneath the stones, a faint and distant sound, waited.
"Let him live," Talia said, and her voice was steady, and the steadiness of it cost her everything she had. "Let him live, and put him to work. He is the only smith in this city who knows the channels. He is the only smith who can undo what he has done. If you kill him, you lose the channels. If you lose the channels, you lose the chance to turn Rendyll's device into our own."
She paused.
"And I will not pretend," she said, "that this is mercy. It is not mercy. It is arithmetic. It is the same arithmetic you have been doing all night."
Maren looked at her for a long moment. Then she turned to Sergeant Hulsten.
"Bind him," she said. "Bind him to the bench beside the other. Take them both to the lower gallery. Post a guard. Do not let them speak to each other. Do not let them speak to anyone."
She turned back to Talia.
"You will lead the smith down into the channels yourself," she said. "You will show him where the chain is to be laid. You will watch him undo every link. You will not speak to him while he works. You will not look at him. When the work is done, you will bring him back up, and you will deliver him to me, and I will decide then what is to be done with him."
Talia nodded. She did not trust her voice to speak.
"One more thing," Maren said.
She waited until Talia met her eyes.
"When this is over," she said, "you and I are going to have a conversation about fathers. We are going to have it in the lower gallery, where no one can hear us, and you are going to tell me everything, and I am going to listen, and I am not going to offer you any comfort, because comfort is a thing for people who have not yet learned to live with what they have done."
She paused.
"That is my promise to you," she said. "As your commander. As your friend."
Talia's jaw tightened. She turned on her heel and walked to her father, and she cut his bonds from the chair with her long knife, and she hauled him up by the collar, and she led him out into the corridor, and her boots rang on the stone in the steady rhythm of a woman who had decided to keep walking until the walking was done.
Maren watched the doorway for a long time after they had gone.
