Brant laid his hook across the old threshold.
"Nobody crosses my iron."
Vera stopped outside the red route mark she had painted two nights ago. Three warning slips still clung to the walls. Her liability stroke split at the threshold, and the room beyond held rat stains, two parallel roller scuffs, and a clean rectangle where a chest had been.
Brant tested the first pace, the corners, and the rear wall. The hook point found nothing until a draft lifted the back warning.
Blue-gray chalk showed beneath the paper: a hook, a cup, and a trailing line rubbed to resemble a boot scuff.
Tess looked away. Holt’s prayer cord stopped moving through his fingers.
Vera turned to Tess. "Tell me before Brant finishes clearing the room."
Tess already had the chalk stub in her hand. She set it on the hook shaft between them.
"I put the code there after you left. Intact recovery. Quiet cart, warded chain, enough paid backs to move a live capture." Her mouth tightened on the last two words. "I used your seal to hide the invitation inside proper work. If somebody else read it first, we may be following their crew."
Holt spoke before Vera could look at him. "I watched her place it. I meant to tell you at the bend. Then there was another bend."
The prayer cord bit into his palm.
"You surrendered tools after the vote," Vera said to Tess.
"I kept the one I thought could get the chest out alive."
"Under my name."
Tess left that accusation unanswered.
Vera’s license number ended less than a handspan from Tess’s blue hook. She pocketed the chalk.
"Room is clear," Brant said. "Fresh tracks. Thirty breaths before feet ruin them."
Vera took the blue chalk off his hook. "Tess, rear position. You name hardware before Brant touches it, and your hands stay to yourself. Holt, write that order first. Then write every one after it."
Holt opened his field book with the hand that was not holding the cord.
"If we come back," Vera said, "you both finish this conversation."
Brant lifted his hook. Vera crossed behind it and knelt beside the empty rectangle.
The left roller scuff cut deeper. Two crescent gouges scarred the stone beneath the old footprint. One barely caught; the other tore a dark channel toward the rear wall.
Brant fitted his hook into each mark. "First bar slipped. Second took the weight. They tipped the left side and dropped it once."
Fresh resin had broken from something cured and black-red. Vera sketched it, then followed her cracked liability stroke to a seam behind the rear warning.
Brant drove his hook into the seam. Mortar burst. A low slab shifted inward over greased rails, exposing a chain-wheel recess and heel marks crowded around it.
Tess stayed at the rear. "Roller brake on the left. Chain pawl under the wall eye. The people guiding the base would stand where those narrow heels overlap."
Six separate tread patterns crossed there. Holt’s pencil paused, then kept moving.
Beside the brake, one heel had skidded and another had pivoted twice in the same grit. The crew had hurried along familiar bars.
Brant checked the service groove. "It moved the chest after learning you wake its mouth. This route is meant for you."
"Then the repair notice gave us only this morning." Vera closed her field book. "We take the trail while it still has edges."
"You stay second. If the floor changes behind us, you turn around when I say it."
Holt looked into the service tunnel. "How do we know it changed behind us?"
Brant pulled a white chalk stick from his hook case and handed it over. "Arrow at every branch, pointing out. Count them backward. If one goes missing or turns, you call retreat before prayer."
He drew the first arrow on the exposed slab and scraped a line through it with his thumbnail. "So I know mine from theirs."
Brant touched the hook point to the mark. "Now we have a way home."
They entered in order: Brant probing rail, floor, and stone; Vera sketching without touch; Holt marking branches and whispering the reverse count; Tess naming each piece of staff hardware from the rear.
Behind Brackenvault’s visible rooms, copper pipes sweated hot water onto their collars while rat grates pulled damp straw air through the walls. Thumb-sized doors snapped shut ahead of the lamp. At one crossing, a pale worker with too many elbows hurried past with a stiff brush and a bucket of black wax.
Tess stared after it. "It has a cleaning shift."
A rat-feed shutter opened somewhere behind them. The rails hummed under their boots.
Brant’s fist rose. Four bodies stopped.
Holt checked his last arrow and held up three fingers. They waited for the vibration to fade; Brant tested the rail before moving.
Ahead, four sets of feet reached Dane through the floor.
Brant’s heel landed first, heavy and measured. Vera followed with the pause she took whenever a surface might answer. Holt kept an exact distance behind her. Tess rode the outside edge of one boot and now walked farther back than before.
The five shallow coppers trembled near Dane’s rim.
The tremor ran through thin silver, dragged red string across the stiff glove and scarf, clicked the brass charm against the nicked knife, and died below his tongue.
Moderate pressure warmed the ownership nail at Vera’s approach. His body found her through stone and air: pulse, throat, wrist, the wet give beneath skin. His lid loosened toward the angle Brackenvault preferred.
Dane ground the crooked pin into his split left hinge and dragged the lid below the inviting angle. With both strains still alive, his tongue reached the copper that had shifted during transport.
He rolled the copper until its slick face rested against his tongue and the gritty stamp faced away from the lure. Two shallow pairs and one slanted center pressed crookedly against his contact map.
Stone scraped along stone. The service door opened.
Brant’s hook tapped the floor inside, then the two edges. Each strike traveled through the room and into Dane’s base. One pace entered. The others waited.
"Three grates," Vera said from the groove. "Ceiling track. Every straw channel bends toward the chest."
The ownership nail heated at her voice.
"Stay behind my hook," Brant said.
Her next step stopped short of the iron point.
A clasp opened. Pine-cold ward pressure touched Dane’s nail and recoiled through the same scarred route. The contact ended there.
Holt let out one unsteady breath. "Found him."
Waiting sharpened Dane’s hunger.
"The coppers changed," she said.
Her boot shifted sideways, never closer. Moderate pressure tracked the movement along Dane’s teeth.
"Five faces turned away from the gap," Vera continued. "Two pairs and one crossing them."
Tess’s outside-weighted tread scraped behind Holt. "Collectors polish what a buyer sees. Those are all wrong."
"Or exactly right for bait made for you," Brant said.
Holt whispered, "A warning?"
Vera took her time. "I know somebody chose which sides showed. I don’t know what they meant."
Dane ground the hinge harder and kept the lid low.
A chain ticked overhead.
"Back," Brant said.
One of the low grates exhaled wet straw, mana, and the living salt of Vera’s skin. Dane’s tongue swelled toward her. His lid surged against the split hinge. The slanted copper rolled far enough to lose the scar beneath one edge.
"The center moved," Vera said.
Her ward pressure retreated half a pace, but her voice stayed level. "Let me go left. No closer. If the same coin moves with me, the room is using my position."
"No. The floor just armed itself."
"Then we leave knowing it can imitate a choice and never learn where the imitation starts."
Brant’s hook dragged along the left wall, struck floor, and withdrew. His boot tested the stone beside Vera’s.
"Give me your sleeve."
Fabric rasped. Brant’s weight settled against Vera’s through the floor.
"Half a step," Brant said. "Heel where my hook landed. I pull, you stop."
Vera waited until his stance stopped shifting. Then one boot slid left along the wall.
The hook point tapped stone to Vera’s left. Her heel landed on a different plate, and straw whispered under it.
Click.
The catch snapped through the floor into Dane’s base. Cloth jerked. Brant’s hook shaft rang against falling stone, and the chain above screamed through its track.
A slab drove the air ahead of it. Hot dust blew through Dane’s rim. Iron struck rock hard enough to jump the deep silver and hammer the room through every band in his body.
The slab hit its floor channel.
Holt shouted Vera’s name from the far side. Brant’s hook scraped once across the stone, found the seam, and bit into it.
"Tess, off the track," Brant ordered.
Tess’s outside-weighted tread stopped beside Holt’s.
Vera’s pulse remained inside.
"Unhurt," she called. Her voice came from three paces in front of Dane. "Pillar at my right. Latch behind me. The chest hasn’t opened."
Moderate pressure tightened around the last sentence.
Beyond the slab, Brant ground his hook deeper into the seam.
Her pulse kept its three-pace rhythm. The ownership nail heated, and one tooth eased from its fold.
