The Shearing Edge

Beneath the rear hub, the sandstone spur gave a terrifying crack. A slab the size of a tabletop sheared off and tumbled into the wash, leaving the axle hanging entirely in mid-air. The wagon lurched sideways, the full weight of the bed and grain sacks coming onto the single manganese chain.

Brisket was dragged backward two inches, his obsidian claws screeching against the bedrock, leaving white gouges in the ancient stone. The hound gave a sharp, pained grunt, his rib-plates expanding as his lungs fought for air under the crushing compression of the chest-strap.

"Hold the stone, Brisket!" Hayes roared, throwing his entire body weight onto the ash pry-bar. His blistered right arm screamed with pain as the raw skin tore against the rough wood, but he drove the wedge deeper under the shifting carriage frame, using his shoulder as the pivot. "Do not give him an inch! Dig, boy! Dig!"

Brisket’s eyes flared with stubborn, feral fury. Instead of pulling with just his legs, the hound lowered his heavy head, locked his jaw muscles, and threw his bulk into a rotational twist, using the wide, low stance unique to his breed. The plates along his spine flared outward, locking together like an articulated arch of iron shingles to distribute the load down through his heavy hip-bones.

With a bone-jarring groan of strained oak and screaming iron, the wagon moved.

It did not slide smoothly. It came up in a violent, shuddering heave. The rear iron tire caught the unbroken edge of the inner highway curb, bit into the stone, and rolled upward. Brisket took one ground-eating forward step, his claws tearing two-inch furrows into the pavement, then another.

"Tolliver, jump!" Hayes yelled.

The driver kicked himself free of the shifting grain sacks and tumbled over the high side of the buckboard, landing hard on his ribs on the solid stone roadbed.

A split second later, Brisket gave one final, savage lunge. The wagon’s front axle cleared the fracture gap with a heavy, concussive slam, the entire wagon righting itself onto three wheels, the bare iron axle-stub gouging hard into the safe side of the curb.

Behind it, the remaining thirty feet of the sandstone ledge finally surrendered to gravity. With a deafening, echoing roar, the entire outer shelf of the canyon mouth collapsed into the ravine, sending a choking geyser of white dust and pulverized lime billowing up into the night air.

Silence rushed back into the gorge, thick and suffocating.

Hayes dropped the pry-bar. His knees hit the stone, his breath coming in ragged, shallow gasps. His right forearm was bleeding where the blisters had burst against the sleeve, the blood dripping slowly from his knuckles onto the dusty paving stones. Beside him, Brisket stood shivering with exertion, his sides heaving like bellows, thick ropes of clear saliva dripping from his jowls to sizzle against the hot scales of his forelegs.

Tolliver lay five paces away, coughing violently on the stone dust, his hands clutching his bruised ribs. "Merciful heavens... merciful heavens..." the driver wheezed, his face gray with shock. "The whole shelf went. The whole damn thing just melted away."

Fiona walked slowly forward, her arbalest lowered, her boots stopping at the jagged, raw precipice where the road had been five seconds before. She looked down into the thirty-foot drop, where the shattered remains of the ledge and the dead draft mule lay in a tangled heap of dry boulders, then looked back at Hayes and his trembling hound.

For several seconds, she said nothing. The pragmatic arrogance was gone from her posture. She stared down at the shattered stone like a merchant tallying a ruinous loss on the ledger.

"You were right, Carver," she said quietly, her voice devoid of its earlier sharp edge. "That was no natural collapse. The fracture face is as smooth as a sawn plank."

"I told you," Hayes said, pushing himself up from the ground with a grunt of pain. He walked over to Brisket, running both hands down the hound’s thick neck to check for pulled ligaments or strained tendons. The beast was hot to the touch, his furnace cooling down to a manageable idle, but his legs were solid and his spine was straight. "He bored the underside so the weight of the second axle would pop the shear pins. If you had sent the heavy freight wagon in first, the whole team and two and a half tons of copper would be at the bottom of that ditch."

Brisket snorted, shaking his heavy armored head until his ear-flaps clicked. Then, lowering his snout to the ground, the hound nudged Hayes’s leg with his nose, gave a sharp whine, and clamped his teeth onto the mangled, twisted manganese trace-hook that had snapped during the haul. With three methodical crunches of his heavy molars, Brisket bit the two-pound piece of forged metal clean in half, swallowing the rear lug with a satisfied gulp before looking up at Hayes with expectant, amber eyes.

Hayes let out a short, dry breath that was almost a laugh. "You just saved eight hundred pounds of grain and a driver's skin, boy, and all you want is to eat the scrap iron out of my repair kit."

Brisket gave a low, rumbling burp that carried a puff of gray ash, then licked Hayes’s bloody knuckles with a tongue as rough as wood-rasp.

"Can we bypass the drop?" Fiona asked, turning back toward the remaining wagons. Her guards were already setting up a defensive perimeter with heavy pavises, keeping their torches low while crossbowmen watched the dark scrub for approaching stalkers.

"Not with the freight wagons," Hayes said, wrapping a clean strip of linen tightly around his torn forearm. "The gap is fifteen feet wide. We'll have to bridge it with spruce spars from the spare timber cart, or find the high trail around the western bluff. And we don't move an inch until I know what is sitting on that rim."

Before Fiona could answer, a sharp, metallic clatter echoed from the sandstone cliffs above them.

It was not the sound of a rockfall. It was the deliberate, ringing strike of a single stone dropped from a height of two hundred feet.

The object fell through the darkness, tumbling end over end before striking the hard surface of the highway fifteen paces from where Hayes stood. It cracked on impact, splitting along a natural seam, but the pieces did not shatter into dust.

Hayes lowered his billhook, stepping forward until the sole of his boot met the edge of the fallen stone. Brisket followed close, resting his heavy chin against Hayes's knee, amber eyes fixed on the dark rock.

The river slate had split cleanly along a natural grain, wide as a man’s chest. Across its face, painted in dark-red oxblood that still glistened under the hooded lantern, was the three-lobed root glyph of the valley’s buried builders. When Hayes turned the heavier fragment over with the iron toe of his boot, the underside revealed four circular, diamond-ground scoring rings—the exact spacing of the harmonic foundation anchors supporting the highway's roadbed. The man above had not merely dropped an ambush; he had delivered a surveyor's mark, declaring that every foot of pavement ahead was already slated for the drop.

Hayes knelt in the dust, running his calloused thumb over the cold, scored slate.

"Fiona," Hayes said, his voice dropping into the quiet gravel of the gorge. "Unhitch the teams and set the wheel-chocks. We are done trying to roll forty tons of freight over a dead foundation."

He stood up, resting his bandaged hand against Brisket’s warm, plated shoulder. He did not look up into the dark cliffs again. There was no need to search the heights when the message had already landed at his feet. They would brace the timber carts here in the wash, take the mountaineering tackle from the lead locker, and climb the western chimney on foot before the first gray light touched the canyon rim.
