A Knuckle on the Sump

The vibration began in the marrow of the pilings before it reached the crew's ears—a heavy, hollow thud that set the clinging barnacles weeping salt water into the dark. Overhead, Sergeant Corin's iron-shod cudgel struck the surface planks with rhythmic, plodding patience, sounding each balk of oak for rot or hollow pockets. Bramblefoot lay pressed against the greasy slope of the drainage arch, his chest pinned flat against the river silt while his elbows clamped the salvaged scraps of the calfskin manifests into his ribs. Beside him, Pip curled into an awkward knot, shivering in sodden waders that reeked of harbour scum, a crust of pale mill-flour flaking from the wet leather seams of his boots with every involuntary twitch of his calves.

A sharp autumn gust drove off the river channel, howling through the open weir piles and shoving a pocket of cold air down the vertical municipal drainage chute. The iron grate above their heads shuddered in its stone seat with a clatter of rusted iron. Up on the masonry shoulder, where the customs collectors had hammered brackets to hold iron boundary rods decades ago, the draft caught an old copper tally-token left balanced upon a lip of salt-rotted mortar. The coin teetered, broke free of its crust of green verdigris, and began a clattering descent down the curved stonework.

Every tap echoed through the pipe like a hammer on an anvil. The disc bounded from the brickwork, struck a corroded valve flap with a bright, metallic chime, and skittered down the masonry run toward the open gap of the lower sewer pit. Bramblefoot closed his eyes and buried his forehead in the wet sludge, bracing for the inevitable shouts from the staging above. Pip drew his knees up toward his chin, helpless to arrest the thing as it bounced once off the toe of his boot and spun on its rim toward the black water swirling below.

Jory moved before the coin could clear the ledge. With his spectacles sliding straight down the bridge of his crooked nose and his ruined knees scraping hard against the slime-slick flagstones, the old tailor thrust one arm into the gloom. He misjudged the distance in the shadows, barking his knuckles against a jagged shelf of lime mortar with enough force to tear the skin, but his fingers splayed wide and came down flat over the spinning disc just as it tipped past the edge. His palm struck the stone with a dull, fleshy smack, pinning the coin flat against the lip of the pit.

For three agonizing beats, none of them drew breath. Water dripped from Bramblefoot's beard into the muck. Above the ceiling timbers, the methodical thuds of Corin's cudgel ceased. The yellow glare of the watchman's brass lantern filtered down through the seams between the planks, striping Bramblefoot's sodden coat in pale bars of amber, and a heavy tread paused directly over the grate.

"Check the salthouse gate," Corin's rasp drifted down through the timber joints, muffled by hemlock and mist. "Nothing down here but weed and bilge rats. If they're on the lower water, they've drifted toward the basin by now."
