The southern crawlspace beneath the dining room was not a cellar; it was a burial trench of dry earth, stone rubble, and old timber shavings.
To enter it, a man had to drop through a narrow hatch hidden beneath the taproom bench, slide his shoulders through an eighteen-inch opening in the masonry, and crawl on his belly through thirty feet of choking, cobwebbed dark. The ceiling joists hung barely two feet above the dirt, rough-hewn beams of white mountain oak that smelled of dry-rot, mouse droppings, and the bitter dust of sixty years of unwashed floorboards.
Jon Hale lowered himself through the hatch, holding a shielded tallow candle in his left hand and a heavy iron-banded mallet in his right. Tucked into the leather waistband of his trousers were three wedges of dense, cured heart-of-oak, each eight inches long, three inches wide, and planed to a razor taper by his own draw-knife two winters ago.
He pulled the trapdoor shut above his head, plunging the crawlspace into yellow candlelight.
“Stay down there, Button,” he muttered toward the hatch rim as a faint scuffling sound echoed above. “This dirt has rat-poison from the autumn culling. It is no place for a bird with one wing.”
A dry croak answered through the floorboards, followed by the light click of the rook’s claws retreating toward the warm hearth.
Jon turned onto his stomach, resting the mallet on his forearm, and began to crawl southward through the dust. The cold earth pressed against his chest through his woolen vest, smelling of lime and dried river clay. Above his head, the dining room floor creaked as Elin set out pewter trenchers for the morning guests, her boots striking the boards with that measured, rhythmic cadence he knew better than his own pulse.
He crawled fifteen paces until the air grew colder and the smell of the river became sharp and damp.
Here, at the southern perimeter of the house, the main longitudinal girder crossed from the central granite foundation wall to the outer rubble footing that overlooked the wharf alley.
It was a monstrous piece of timber: sixteen inches square, thirty feet in span, cut from an ancient white oak that had grown in the limestone ravines before the first bridge was arched. For sixty years, it had carried the weight of the dining room floor, the brick chimney breast of the corner fireplace, and the heavy plaster partitions of the second-floor guest chambers.
Jon held the tallow candle close to the wood, squinting through the drifting smoke.
The timber looked sound to an ordinary eye. Its surface was black with age, scored with the broad-axe marks of the original woodsmen, and encrusted with the gray cocoons of wood-wasps. But four feet from the outer stone sill, where the timber crossed the hidden drainage flume that carried water from the scullery sink, the wood was darker, stained with a dull, greenish discoloration where moisture had wicked up from the subsoil.
Jon reached out his right hand, his thumb running along the underside of the girder.
His fingers found it.
A hairline crack, no wider than a horsehair, running diagonally across the grain of the heartwood for twenty inches.
To an imperial inspector or a casual carpenter, it was merely a seasoning check, an ordinary shrinkage crack caused by the dry heat of the dining room stoves. But Jon had seen that crack open.
In his second return, during the third night of the siege, a stray mortar shell had exploded in the wharf alley forty paces from the inn. The concussive shockwave had traveled through the river gravel like an iron mallet, striking the outer foundation wall with terrible kinetic force. The rotten core of the girder had sheared in two along this exact diagonal line, dropping the dining room floor four feet into the crawlspace with a concussive roar that brought down three courses of granite from the wall above.
Nell had been crossing the room with a pitcher of water for the militia wounded. The floor had collapsed beneath her feet, and the falling masonry had buried her before she could scream.
Jon had dug her out in the dark, her small ribcage crushed beneath eight hundred pounds of river granite, her yellow hair matted with gray lime dust.
He had lived through four lifetimes since that night, but every time he walked across the dining room floor, his knees remembered the give of the boards, and his chest felt the crushing weight of the falling wall.
“Not this time,” he whispered, his knuckles whitening as he gripped the handle of the mallet. “Not while I have oak and iron.”
He cleared the loose gravel from beneath the girder with his bare hands, digging down until his fingers struck the solid limestone bedrock that anchored the valley floor.
He set the first cured oak shim into the gap between the bedrock and the stone sill, positioning the thick end beneath the sheared grain of the crack. He set the second shim inverted atop the first, creating an interlocking wedge that would drive the load directly into the mountain rock.
He knelt in the dirt, his shoulder braced against the cold masonry of the outer wall, raising the heavy mallet in the confined space.
He swung.
The iron head struck the butt of the oak wedge with a sharp, ringing crack that shivered through the rafters: Clack.
Dust showered down from the floorboards above, gray and choking in the candlelight.
“Jon?” Elin’s voice called down through the floor, sharp and startled. “What is that pounding beneath the dining table? You’ll crack the plaster on the pantry ceiling!”
“Checking the sill, Elin!” he called back, spitting stone dust from his lips. “Keep Nell in the taproom until I finish the drive!”
“Mind the crockery!” she shouted back, though her footsteps moved away toward the hearth, respecting the unwritten covenant they had sealed over the bread board.
Jon raised the mallet again.
There was no room for a full swing. He had to work from the elbow and wrist, using the weight of the heavy iron head to deliver short, concussive blows that drove the dense heartwood deeper into the seam.
Clack.
The oak wedge bit into the limestone bedrock. A thin ribbon of dried sap squeaked as the fiber compressed under seventy tons of structural pressure.
Clack.
The second shim slid home, its grain locking into the first with an unyielding bite.
Jon paused, his breath coming in ragged gasps, his shoulder aching from the cramped angle. He brought the candle close to the crack.
The hairline fissure had closed by half. The wood was groaning now, a deep, resonant timber-creak that traveled through the entire framework of the house, like a sailing ship rising on a swell.
He took the third wedge—the locking key—and set its slender lip between the two timber faces.
He took a slow, deliberate breath, steadying his hands against the vibration in the wood. He called upon the ancient trade authority of his class, sending a pulse of Warm Room through his palms into the cured oak shims, softening the dry grain just enough to allow the wood to bite without splitting.
The blue line flared across the wedges:
STRUCTURAL REINFORCEMENT DETECTED LOAD REDIRECTION: BEDROCK BEARING MARGIN OF SAFETY: FOURFOLD
“Seat the core,” Jon whispered. “Take the weight of the house.”
He swung the mallet with all the force his broad shoulders could muster in the dirt:
CRACK.
The blow sounded like an iron axle snapping on a turnpike.
A shudder ran through the entire length of the thirty-foot girder. The floorboards directly above his head rose a quarter of an inch with a dry, squealing pop of iron nails, lifting the sagging timber back into perfect horizontal alignment. The diagonal fissure vanished completely, crushed shut beneath the upward thrust of the bedrock shims.
The oak had taken the strain. The floor was no longer suspended over a rotten void; it was anchored to the solid granite bones of the valley floor.
Jon lowered the mallet, letting his head rest against the cold stone of the sill. He was sweating despite the river chill, his hair matted with lime dust, his woolen vest black with soot and dirt.
Above him, the house settled with a final, satisfied groan of timber.
A single set of small, light footsteps ran across the dining room floor directly over his head, accompanied by the joyful clatter of wooden clogs.
Nell.
She was skipping across the floorboards, humming her sheep-shearing tune, completely unaware that two feet beneath her soles, an unyielding pillar of cured oak had just been driven between her living feet and a six-lifetime grave.
Jon lay in the dark earth of the crawlspace, listening to the rhythm of her boots.
One. Two. Three. Four.
The floor did not tremble. The timber did not groan. The masonry held firm as a fortress wall.
He closed his eyes, a single ragged breath escaping his throat, his forehead pressed against the rough bark of the girder.
“One room safe,” he whispered into the dirt. “One child alive.”
He wiped the sweat from his eyes with the back of his sleeve, picked up his candle and mallet, and turned onto his belly to crawl back toward the taproom hatch.
There was fifty yards of river wharf to inspect before the seventh bell, and Sir Cael Ardent was thirty miles closer to the gate.
