The note came again through the soles of Mara’s boots.
Not a chapel bell. The sound was too close and too dull, its iron throat muffled by peat. Three strokes, a pause long enough for breath, then three more.
Nella dropped to one knee beside the nearest stake. She pressed two fingers into the rut and brought them up shining black.
“Road’s laid over a hollow,” she said. “Old one, by the taste of it.”
Caldus looked at her fingers. “You tasted it?”
“Not with my mouth, bookman.”
Pell remained mounted. Rain pearled on the brim of his hat and ran from it in an orderly line. “Could the bell belong to Vigil Nine?”
“Vigil’s north and uphill.” Nella wiped her hand on the stake’s white cloth. “Sound’s under us.”
The horses knew it. Teren’s grey had planted its forefeet and stretched its neck, nostrils working. Ivo’s bay worried the bit until foam threaded its jaws. Behind them, one of the baggage animals tried to turn in the traces.
Mara crouched beside Nella. The painted Office device had left a greasy black smear across her glove. Lampblack, linseed oil, pine spirit. Fresh enough that the resin still bit through the wet-earth smell.
She pinched the cloth below the mark.
“Do not touch that,” Pell said.
“You might have mentioned poison before I touched it.”
“I did not say it was poisoned.”
“Then you object to fingerprints on bad painting.”
Pell dismounted with deliberate care. “I object to interference with a Crown closure until its purpose is established. Would you allow me that modest professional instinct?”
“No.” Mara rubbed the cloth between thumb and forefinger. It was good linen, closely woven, torn from a wider bolt rather than cut. “This was painted today.”
Ivo drew his sword and used the point to lift another strip. “Your clerks move fast, Pell.”
“My clerks do not mark closures without a written notice.”
“Perhaps the rain ate it.”
“The rain is not trained to remove sealing wax.”
The bell struck again.
This time the road answered. A faint trembling passed through the pooled water in the ruts, making rings inside rings.
Teren swung down. “Get the carts back.”
“There is no back,” Nella said. “Not with the west road under brown water and half your pretty cavalry packed behind us.”
“Then get their weight off this stretch.” He turned to Ivo. “Ten riders south. Walk the horses. Spread them along the verge.”
Ivo glanced at the white stakes. “You giving orders to the mud now?”
“I’m giving one to you.”
The plainness of it stopped Ivo’s smile. He sheathed his sword and began pointing riders away in pairs, abusing each man’s intelligence as he sent him.
Mara looked down the resin track. The closure crossed it from ditch to ditch, but the stakes were shallow. Ceremonial obstacles. Beyond them the road climbed for twenty yards, dipped beneath tangled alder, and vanished.
A cord ran from the foot of the third stake into the ditch.
It was the same brown as the water. Mara saw it only when rain struck and slid along its waxed surface.
“Nella.”
The ferrier followed her gaze. “Bell line.”
“To warn travelers?” Caldus asked.
“To call them.” Nella’s voice had lost its color. “Fen folk string a line when a roof goes under. You pull till somebody with a shovel hears.”
Mara stepped over the ditch.
Teren caught the back of her coat.
She turned her head. “Release me.”
“When the ground is tested.”
“The cord is tied to the closure. Whoever drove these stakes saw it.”
“And may have left it as bait.”
“Then stand here and admire their craftsmanship.”
He did release her. Before she could move, he unbuckled the long leather strap that secured his cloak roll, looped one end twice around his wrist, and offered her the other.
Mara stared at it.
“You need not marry the strap,” he said. “Only hold it.”
She took it. The leather was warm where it had lain against him.
Teren tested the verge with his scabbard, driving it down before each step. No speech about caution. No hand placed at her waist as if ownership improved balance. He merely gave her enough slack to choose her ground and followed where she chose.
That precision lodged inconveniently in her attention.
The cord disappeared beneath alder roots at the base of the rise. Mara pulled once. Far below, metal scraped, followed by a weak half-stroke of the bell.
“Someone is on it,” she said.
Teren knelt beside the roots. A square of darker earth showed beneath the dripping leaves. He scraped mud away with his glove and found planks, their edges tarred against water.
Nella came across carrying a short ash pole. “Peat door. Mind the hinge side. If the bank’s swollen, it’ll spit the whole roof at you.”
Pell stepped over the closure behind her. “Inspector’s authority. No one opens anything until I have examined the mark.”
“There is no mark,” Mara said.
“That itself is relevant.”
“So is breathing.”
She put her face near the seam between planks. The air leaking through was warm and carried tallow, wet wool, human waste, and a dry metallic odor that caught high behind her nose.
Not rot. Not marsh gas.
She sat back. “No flame.”
Ivo, approaching with a lantern, halted. “Wasn’t offering you one.”
“Put it out.”
He looked to Teren. Teren pinched the wick between his gloved fingers. Darkness closed around them except for the grey wash of afternoon through rain.
Mara smelled again. There: a sweetness beneath the metal, like scorched fruit skins.
“Open from upwind,” she said. “Slowly. If anyone feels headache, sourness in the mouth, or weakness in the knees, say it before you fall.”
Caldus had remained by the carts. “What is in there?”
“If I knew, I would have used its name.”
Nella worked the ash pole beneath the plank. Teren braced beside her. The first lift broke the tar seal with a wet ripping sound. Air breathed out of the hollow.
Ivo swore and covered his nose.
Mara did not. Smell was evidence, and cloth removed distinctions. The metallic sweetness strengthened, mixed now with vinegar and old smoke.
“Again,” she said.
The plank rose the width of a hand. Fingers appeared in the gap.
They were stained white to the knuckles.
Teren shifted his grip at once, taking the weight from Nella without crushing the reaching hand. “Move back,” he said into the dark. “We’re lifting it.”
A voice answered, too faint to separate into words.
Ivo wedged his scabbard under the door. Together they hauled it upright. Mud sloughed from the planks. Beneath lay a steep stair cut into peat and shored with resinous pine.
Faces looked up from below.
Mara counted six before they began moving: two women, an old man, three children. Then another shape stirred behind them. All wore white cloth bound over their mouths. The cloths were marked with the black crown and dividers.
The eldest woman climbed first. Her bare feet slipped on the peat steps. Teren went down two treads, turned his back, and let her grip his shoulders while he brought her up. He did the same for the old man. He did not hurry them, though the smell rising from the chamber made Ivo pace away into the rain.
The children came without speaking. White dust lay in the creases around their eyes and beneath their nails. The smallest girl clutched the bell cord in both hands. Friction had opened her palms.
Mara took a water flask from Pell’s saddle.
“Small mouthfuls,” she told them. “Do not wash your hands into the ditch.”
The eldest woman tore the cloth from her face. She was perhaps thirty, though the skin at her mouth had the slack grey cast of greater age.
“You Office?” she asked Pell.
“I am Inspector Odran Pell of Bounds and Assay. Who confined you here?”
The woman laughed once. It ended in a cough. “Confined.”
Pell’s softness did not alter. “Who closed the road, mistress?”
“Your men.”
Rain ticked on the upright door.
Pell took a leather case from inside his coat and showed his badge. “Look carefully. Was this the device they carried?”
The woman did not look. She pointed at the cloth hanging from the stakes. “Had it on their cart. Had it on the sacks. Had it on every door they nailed.”
Mara glanced down into the chamber. Shapes resolved as her eyes adjusted: pallets, a cold brazier, crockery, a barrel with its lid stove in. White powder crusted the floor beneath it.
She caught Teren’s sleeve before he descended again.
“What?”
“Your spur.”
He understood before Pell did. He unbuckled it and handed it to her, then removed the other. Iron striking stone was unlikely in a peat cellar, but unlikely was a word used by people whose hands had not yet burned.
Mara wrapped her mouth with a clean strip from her satchel and went down.
The powder gave off almost no odor close to the floor. She touched a glass rod to it, then dipped the rod into rainwater collected in a cup. The water clouded faintly. She added one drop from the smallest blue vial in her case.
Yellow spread from the rod like bruised sunlight.
Behind her, Pell said, “Mistress Veylan.”
“Stay on the stair.”
“Is it blasting material?”
“No.” She examined the yellow precipitate. “Arsenical lime.”
The eldest woman spoke from above. “They called it rat-white.”
Mara looked at the barrel. A branded plank lay half buried beneath the spilled powder. She used Teren’s scabbard to turn it.
The Crown device was burned deep into the wood. Below it were the words OFFICE OF BOUNDS AND ASSAY, EASTERN STORES.
No one spoke for several breaths.
Mara climbed out and stripped off the cloth over her mouth. “How long were you below?”
“Since yesterday noon,” the woman said. “They said the dust cart split and the rain would carry it. Put us in the keeping-hole while they cleared the road.” Her eyes moved to Pell’s badge at last. “Then they drove stakes and went away.”
“Which direction?” Teren asked.
“North.”
Toward Vigil Nine.
Pell crouched before the smallest child, though the girl turned her bleeding palms inward. “How many officers were there?”
“Do not question her yet,” Mara said.
“We must identify the party.”
“You must find clean water. They need their skin washed with wood ash soap, then water again. Their clothes must be buried away from any spring.”
Pell rose. “Arsenical compounds are not issued for road work.”
“They are issued for killing vermin in record stores and assay depots.”
“Under controlled warrant.”
Mara pointed to the yellow stain still creeping through the cup below. “Control appears to have gone north.”
His gaze held hers. His face remained fatherly; only his thumb moved, rubbing the edge of his badge until the leather creaked.
Teren took off his cloak and laid it around the eldest woman’s shoulders. The lining was Rusk green. She flinched when she saw it, but he left his hands open and waited until she closed the cloak herself.
“Where are the rest?” he asked.
The woman looked past him toward the white stakes.
“This isn’t the closure,” she said. “This is only the first door.”
