The Shear Point

Balbina did not seal the shaft that night. She weighed the wedges in her hands, looked at the onion-skin sheet bleeding against Arana's thigh, and said the report would be closed on the ninth level or not at all. Then she disappeared down the haulage drift, in the dark, the way she had come.

The next day, a little past noon, Arana and Lafuente went down again.

The winch cable hung slack across the crossbeam.

Arana stopped three rungs from the floor. The rusted iron of his knee brace struck the rotting wood of the ladder with a hollow, dry snap that vibrated straight into his kneecap. He waited. With his right hand he patted his hip to make sure the leather portfolio was still there, wedged beneath his belt. The sheepskin was slimy from the condensation dripping down the shaft walls, lukewarm water that smelled of slaked lime and old urine. Up above, a hundred meters toward the mouth, nothing could be heard. No shouts from the laborers. Not even the steam engine.

"The cage is stuck at the top," Lafuente said from below.

He was sitting on a shoring timber, his feet sunk in a grayish mire. He took off his beret, shook the white dust from it against his thigh, and put it back on, settling it firmly over his ears.

"Listen," Lafuente added, staring at the black ceiling. "Got any tobacco that isn't soaked?"

"No."

"I've been dying for three hours to burn something that doesn't smell like dead stone."

"Right."

Arana descended the last two rungs. His bad leg missed the mud of the floor by half a palm; the hinge of his prosthetic gave way with the sour squeak of an ungreased joint. He had to press his palm against the side wall to keep from pitching forward. Living rock did not exist down there: the basalt surface was lined with a thick crust of whitish grout that stuck to his fingers like raw bread dough. He wiped his hand on the black cloth lapel of his frock coat, leaving a faded, pasty stain that would take weeks to dry.

The trouble was that Balbina Cuesta was not cold.

She stood by the headwall of the ninth level, her arms crossed beneath a fine cloth shawl and a carbide lamp hanging from an iron hook at eye level. The flame reeked of acetylene and cast a triangular shadow, sharp as a wedge, against the face of the fracture. She hadn't stained her boots. Not a single splash of mud. Her hair was pinned back with a tortoiseshell comb that glittered every time she tilted her head to look down the gallery, as if she were waiting for a horse-drawn carriage on a clean street corner.

"You're twenty minutes late, clerk," Balbina said. She didn't even blink. "The masonry of the east side wall has been giving way since twelve. If the keystone crushes before the linen is run, you answer with your bond."

"The cage came down slow," Arana said. His tongue tasted of cold metal, of that rust that got into his molars every time he dropped below the sixth level. "Lafuente, get the plumb line out."

"The weight is full of grime," Lafuente grumbled, rummaging through the wooden box resting on the sleepers. "The sheep tallow has turned green with the humidity. It stinks like a rotting ram."

"Get it out anyway."

The thing was that nobody cared about the stench of the tallow, except for Lafuente, who still believed that an underground boundary survey was done with clean gloves and hot coffee waiting in the adit canteen. Arana opened the portfolio. The onion-skin sheets rustled between his fingers with that false stiffness of paper that has absorbed too much groundwater; they were swollen, with edges curled like old wafers. Lime dust had worked its way beneath the cuticles of his thumbs, forming a hard white rim that tugged at his raw skin every time he folded a leaf. He scratched the base of his nail against his vest buckle. It hurt a little, but at least it didn't itch.

"The draft has reversed," Lafuente muttered, lifting the zinc plumb bob attached to the leaded-linen measuring tape. "The bellows aren't drawing toward shaft three anymore."

The hissing began beneath the sleepers.

It wasn't a violent escape. It sounded continuous, low, like the torn bellows of a blacksmith's forge when the leather loses air through the seams. A lukewarm, sour vapor laden with alkaline particles that made the eyes sting began to seep through the microscopic cracks of the wet basalt. Arana felt the immediate burn at the back of his throat. He swallowed, but managed only to swallow dry dust.

"Extend the tape," Balbina ordered. She took a step forward; the hem of her skirt brushed the mass of mud without seeming to bother her. "From the master face to the sharp edge of the fissure. Exactly thirty yards. If it reads twenty-nine and a half, the consolidation contract is void due to prior collapse defect. You know that, Arana."

"I know it."

"Then don't stand there staring at the wall as if it's going to answer you."

Arana didn't answer her. He pulled the cylindrical black bakelite inkwell from his inner vest pocket. The screw cap was jammed with saltpeter; he had to bite the edge of the bakelite to loosen it. The bitter plastic scraped against the edge of his incisors. Inside, the violet copying ink trembled with a microscopic vibration, a heartbeat coming not from the air but from the very mass of stone they stood upon. The fault wasn't settling; it was floating on a pool of boiling grout looking for a way out.

"Hold the end, Lafuente," Arana said, passing the leaded linen between his fingers. "On the reference nail. On the stone, not the mortar."

"The nail is loose," Lafuente said. He had squatted down; his knees splashed in the gray mud. "The limestone joint is turning to mush, Arana. You touch it and it crumbles like wet plaster."

"Stick your finger in and hold it."

"It's going to burn my skin, damn it."

"Hold it."

A dull crack ran through the vault. It wasn't above, in the timbers, but below, in the blind bed of the gallery. The living rock didn't shatter; it simply opened an inch downward, as if someone had withdrawn an invisible wedge from the depths of the blind shaft. Hot air blew against Arana's cloth trousers with a pestilential force, the stench of a sewer and scorched stone. The basalt rumbled once, a dry blow that shook his prosthetic leg and loosened the adjustment screws.

The ninth level plummeted three palms toward the blind bed.

The blow knocked Lafuente backward onto the mud. The bakelite inkwell slipped from Arana's numb hand, bounced off the sharp edge of the freshly opened fissure, and shattered into three pieces on the rock. The copying ink leaped in a dense stream, dark violet, almost black, before dissolving into the grayish mud in a thick, purplish halo that looked like motor grease on soaked asphalt.

Nothing.

For three whole seconds, the only sound was the hissing of gas escaping with greater force through the new cleft, swelling bubbles of grout that burst in silence.

"The seat has dropped," Lafuente said from the ground, crawling toward the ladder without getting up. "Arana, we're leaving. It's swallowing the footing. We're leaving."

"Stay where you are," Balbina's voice sounded flat, clean, without a single break of fear. "The measurement is not closed. The boundary has no public faith until the folio is initialed on the face. If you leave by that ladder unsigned, I'm filing a complaint for dereliction of duty with the Government Chamber before six o'clock."

Arana wiped his sleeve across his forehead. His sweat mixed with the damp chalk, forming a gray slurry that stung his eyebrows. He looked at the floor. The onion-skin paper had fallen onto a flat stone protruding from the mud; it was stained at the edges, but the body of the document, with the dry seals of the Chancellery still legible, remained intact.

"The inkwell broke," Arana said.

"You have the ink stump in the bakelite," she said. She hadn't moved a centimeter; the carbide lamp in her hand cast a trembling circle over the live fracture, which was now two palms wider. "And you have the plumb line in the air. Measure."

Arana took a deep breath. The gas burned his bronchi, air that tasted of sulfur and lime slaking in a bucket. He thought, for one ridiculous second, of the coffee machine at the railway station, of that metallic hum the boiler made before releasing a jet of lukewarm water with an aftertaste of scorched copper. This was the same thing, more or less. A boiler with nowhere to vent.

He limped to the edge of the abyss. The iron prosthesis struck a basalt outcrop, sending a stab of dull pain from his shin to his groin. He rested his good knee in the mud. The sheep tallow covering the zinc plumb bob gave off a rancid, dizzying stench as he suspended it over the exact axis of the fracture. The linen thread did not oscillate; it dropped vertically toward nothingness, toward a milk-white darkness gurgling five meters below.

"The elevation has dropped four yards," Arana said. His own voice sounded foreign to him, as if it were coming from the bottom of a clay jar. "The side wall is gone. The reactive fault has swallowed it."

"Record the elevation," Balbina said. Her black kid-gloved hand pointed to the mud-soaked file. "The original elevation from the plan. The one the contract agreed to."

"The plan says this is solid rock."

"The plan says whatever the clerk validates with his signature."

Arana raised his gaze. In the green light of the carbide, Balbina Cuesta's face looked sculpted in dry stucco. There was no malice in her eyes; only that absolute, administrative indifference of people who get paid per cubic meter excavated without ever having descended to shovel rubble.

"Recording the truth sometimes requires that the clerk be walled up within the very folio that settles the litigation," Arana muttered.

"Don't be melodramatic, Arana. Sign and come up."

Arana picked up the largest piece of the broken inkwell. The black bakelite retained a pool of viscous ink, half-congealed by the alkaline dust. He dipped the tip of his index finger directly into the thick violet. His fingertip was cracked from the saltpeter; the ink entered the cuts with a sharp sting, cold at first and then burning like acid.

"Lafuente," Arana called without turning.

There was no answer. Lafuente was already climbing the rungs of the ladder; the iron of his boots clattered fifteen meters up, fast, desperate, seeking the mouth of the shaft.

Arana dragged the folio across the slippery stone. With the zinc weight suspended on the exact axis of the live fracture, marking the abyss that widened with every heartbeat, he rested the onion-skin paper on the thigh of his bad leg, right over the sheet-metal reinforcement.

A dull roar, not like thunder but like the snapping of a keel against a sandbar, burst the upper masonry.

A rain of small stones and boiling grout fell upon his shoulders, soaking his frock coat in white mud that burned through the cloth. The master wall bowed inward. Balbina took a step back, the first time she retreated, and the carbide lamp oscillated violently, filling the vault with runaway shadows.

Arana did not look up. He pressed his stained fingertip against the dotted line of the mud-soaked file, tracing his violet signature with a crooked, dense stroke that tore the damp paper the exact instant the first granite ashlar of the keystone broke away from the ceiling.

Silence.

Up above, at the outer adit, a dog barked twice and fell silent.
