The Clatter in the Culvert

The fractured drainage lever had bitten into the palm of Bram's glove before shearing clean, leaving the lower valve fast in its crust of calcified lime. Sludge dragged at his knees with every shift of weight, the stagnant cold of the sump seeping through grease-treated leather. Outside, the muffled weight of whatever prowled the bedrock corridors still leaned into the iron door and the spruce prop he had jammed under its dog-latch, but inside the chamber the air had gone dead and stagnant.

Then a warm amber glow washed over the ceiling.

It did not come from the breached masonry or the upper shaft where Oren had dropped out of sight. The lantern beam cut low and yellow out of an intersecting culvert—a narrow, vaulted brick spillway five feet above the waterline that appeared nowhere on the municipal brass plates Kaelen had studied. The light swayed in time with the rhythmic crunch of hobnails striking wet flagstone. Water trickled and echoed ahead of the bearer, distinct from the dull thudding against the outer hatch.

Bram dropped the broken pipe into the murk, where it sank with a dull thud. He scooped two palm-sized ballast stones from the lip of the sump masonry, the wet grit rough against his raw knuckles. Whoever was moving through the lateral conduit walked with the steady, insolent pace of a man who knew his path, untroubled by the total blackness smothering the world overhead.

"Stand where you are!" Bram shouted, his voice cracking against the damp vaulting. The sound bounded off the curved bricks, loud enough to rattle the scum on the pool's surface. "Drop the glass or I'll stove your head in with five pounds of granite!"

The beam whipped upward in an erratic circle. A muffled curse bounced out of the culvert mouth, followed by the hurried scuffle of boots trying to find purchase on wet moss. The intruder tried to pivot back toward the shadow of the lateral branch, but his trailing heel caught against a square iron rivet jutting an inch out of the lower masonry course.

With a sharp grunt and an undignified flailing of limbs, the figure pitched headlong off the culvert shelf. He hit the knee-deep runoff with an immense, hollow splash that showered the walls with gray foam. A wire-mesh cage and two tin ratting traps went clattering across the stones, their springs snapping shut in empty air as their owner thrashed on his back, sputtering foul-tasting drain water.

Bram did not throw the stone. He waded forward through the sluggish wake, the water parting with a heavy sucking sound around his thighs, until the beam of the fallen lantern—miraculously still burning behind oiled horn panes—illuminated a thin, soot-streaked man sputtering among floating vegetable waste and frayed hemp rope.

"Blasted lunatic!" the man choked, clawing his way onto his elbows and wiping grease from his eyes with the back of a sodden wool sleeve. "Roaring like a siege engine in the dark! There are teeth in these tunnels, you brainless ox!"

Bram stopped six paces off, ballast stone still raised at shoulder height, looking down at the scattered traps, the drowned sack of dried grain bait, and the furious, coughing face glaring up from the mud.
