The Claw in the Culvert

Nico dropped the bolt onto the zinc sheet of the dismantling table. The impact sounded hollow, a dry snap that startled the moths fluttering over the tin plate of rancid lard. For a few seconds neither of them said anything; the boy rubbed the base of his throat with the dirty sleeve of his burlap doublet and looked up toward the roof vent, where a wisp of smoke smelling of boiled cabbage and cold tar drifted down. In the corner of the garret, the steady drip of a purge pipe marked the rhythm of things rotting slowly. It was a gentle noise, like fingers drumming on damp parchment in an empty library.

"It has three notches," Nico said at last, scratching his thumbnail against the splintered edge of the stool. "I've counted them twice. Bruna doesn't let parts out with that stamp unless they're heading for lock lathes six."

"Or the bottom traps," Mateo replied.

"My uncle used to say marks don't mean a thing once the iron cools. He said iron belongs to whoever lifts it out of the mud."

"Your uncle died wedged in a sluice gate for not reading the pass seals."

"Yeah. But he had a pewter spoon with his name engraved on it," the boy muttered, lowering his eyes to the floorboards. "And it didn't help him eat any faster."

Mateo didn't answer. He had his left arm resting on a rag soaked in cold brine, pressing the flesh against the edge of the zinc tub to soothe the bite crawling up his forearm. The pain of the non-human tendons was a cord stretched to the point of complaint, a dull pull that twisted his wrist inward if he grew careless for a second. There were days when the arm seemed to belong to a dead animal hanging from his shoulder; other days, like this afternoon, it pulled with blind greed, demanding the friction of vinegar or frozen grease to keep from snapping the ulna from within. The salt stung in the poorly healed incisions, a clean burn that at least erased the memory of the warmth.

Outside, four blocks away toward the discharge canal, steam hammers pounded the forging blocks with a heavy cadence that made the murky water tremble in the cracks of the ground. It was a continuous heartbeat, the mechanical respiration of a city that crushed ore day and night without caring who collected the shavings.

A crash of splintered wood broke the distance.

It wasn't the dull blast of a boiler releasing pressure or the usual screech of brake shoes against slag hoppers. It was a sharp blow, followed immediately by the strangled bray of a draft beast and an oath cut in half. Mateo was on his feet before the sound had finished dissolving between the concrete walls. The saline rag dropped to the floor with a viscous slap.

"Stay here," he ordered, grabbing the short steel pry bar from the shelf.

"If it's the dock guards..."

"Guards don't scream like they're having their guts pulled out with a cargo hook."

Tanners' Alley was nothing more than a narrow ditch wedged between two refractory brick warehouses, a sump where the hide-washing water ran toward the collectors, forming puddles with violet iridescence and thick foam crests. The air there had the density of a rag soaked in bleach. At the back, near the bend where the condensate pipes spat jets of warm steam behind a soaked tarp, a two-wheeled cart lay overturned on its right side. The box boards had burst against the cobblestone and two dozen salted hides spilled into the mud like crushed corpses.

Two men—teamsters wearing aprons of leather hardened by vegetable grease and hands stained with dark tannin—were precariously perched on the hub of the upper wheel, their backs pressed against the rough concrete wall, covered in silt and dried urine.

Below them, snorting against the muck, waited the beast.

It was a drainage pit dog, but the chemical discharges from the North Dike stills had turned it into a bloated aberration. It lacked fur on its back; instead, a shell of exposed muscle tissue and crusts of yellowish suppuration throbbed with every breath, as if a blacksmith's bellows were working beneath a skin three sizes too tight. Its lower jaw, split into two independent halves by a defective biological weld, dripped thick drool mixed with strands of grayish lymph onto the stones.

The dog didn't bark.

Beasts like that didn't emit warning sounds; they only produced a liquid click when swallowing and the constant crunch of neck cartilage stretching beyond the natural.

Mateo advanced, hugging the shadow of the eaves. The rotting mud muffled the weight of his worn soles, but the creature smelled him or felt the tremor of the damp cobblestone. The dog pivoted on its hind legs—deformed, ending in calloused hooves that dug into the muck—and let out a wet whistle. A strand of synovial fluid hung from its jowls, smoking faintly at the touch of the freezing afternoon air.

"Watch out, foreman!" shouted the older teamster from atop the wheel, his voice cracked by tobacco and panic. "That piece of shit jumped right out of the culvert grate! Its tendons are crossed!"

Mateo didn't answer. He closed the distance crouched low, measuring the interval between the distant hammer pistons. Four blocks north, the blow of the steam maul thundered against the stones; at the third beat, the beast lunged forward as if a compression spring had snapped in its spine.

The clash was brutal. The cleft snout passed an inch from Mateo's shoulder, tearing the fabric of his jacket with the acrid stench of putrid meat macerated in ammonium salts. Mateo slipped on a slab of vegetable grease dropped from the cart, but his left arm—the mass of nemetic fibers burning under his skin like molten lead—reacted before his head could order the movement. His left hand closed over the suppurating fold of the animal's nape. His fingers sank into the living tissue, searching for the anchorage of the tension cables running along his marrow.

The dog writhed, thrashing its back against the cobblestones with the spasmodic violence of an eel on a butcher's board. Its teeth snapped in empty air, chipping splinters of stone inches from Mateo's knees.

Mateo drove his right knee into the oily mud. The seam at his collarbone sent a freezing stab into his throat, but he squeezed. The foreign tendons beneath his flesh responded with a dull crunch, a tug that recognized the proximity of the living biomass pulsing between his fingers.

He drove the steel pry bar into the joint of the animal's atlas.

There was a dull pop, a breaking of dense cartilage that sounded like a wooden mallet crushing dry roots in a mortar. The beast jerked one last time, clawing the concrete curb until its nails split, and then lay still, half its skull sunk in the sewage puddle.

A dense silence fell over the alley, broken only by the hiss of a distant valve spitting white vapor into the leaden sky.

Mateo didn't let go of his grip. He knew what came next; he knew it with the arid resignation of a laborer looking at the last shovel of coal before closing the furnace. He dug the fingers of his left hand deeper, tearing the leathery neck skin until he found the motor cords still vibrating with a warm residual current.

The nemetic tissue adhered to his fingertips with the blind avidity of a leech. A white pain, thin as a red-hot copper wire, shot up his arm, crossed his shoulder blade, and drove into the base of his skull.

Mateo squeezed his eyelids shut. He tried to hold onto his sister's face: the curve of her chin under the yellow light of a carbide lamp, the small scar beside her left eyebrow from falling off the coal bunker wall, the exact tone of her voice calling him from the end of the corridor before they closed the locks.

The image trembled.

It frayed like old gauze in the sun. His sister's eyes turned into two gray, empty spots; the line of her nose dissolved into a milky mist and suddenly there was nothing left of her laughter, nor of the coldness of her hands when they shared the matted woolen blanket.

Instead, with a violence that filled his mouth with bitter saliva, the memory of the pit burst in: the viscous darkness of a flooded culvert, warm and fetid water licking his swollen belly, the crunchy snap of a water rat's vertebrae coming undone between the molars in the blind end of a gallery where clean air never entered.

With a dry heave, Mateo let go of the corpse and fell backward into the mud.

He breathed with his mouth open, swallowing the stench of burnt grease and urine hanging stagnant in the alley. His left arm no longer shook; the newly absorbed tendons had welded to his fibers with a mineral rigidity, leaving his flesh cold and heavy.

From atop the overturned cart, the old teamster climbed down awkwardly, careful not to put his boots in the puddle where the dog's guts floated. He brushed off his apron with both hands, looked at the broken wheel of the wagon, and then turned to Mateo, spitting a thread of black tobacco onto the cobblestones.

"I dropped my sack of coarse salt in the drain," the man said, in a monotonous, tired voice that held not the slightest trace of the terror from a minute ago. "It was four reals' worth of mineral. Now let's see who the fuck explains to the weighmaster that the dirty water swallowed the salt."
