Breaking the Water Gate

How long could an unsteered timber cutter survive in the black water of the Puna'u gorge before the current drove its cedar hull onto the basalt teeth of the riverbed?

Ma'uka had five heartbeats to find the answer. The Puna'u Runner surged down the pitch-black chute of the river, her deck tilting at a sickening angle as sixty tons of mountain runoff caught the flat-bottomed hull. Spray roared over the gunwales, cold as melted snow, drenching Ma'uka's linen tunic and stinging his eyes. Ahead, where the torchlight of Kua'na faded into the mist, the river narrowed between vertical walls of dripping basalt, funneling into the foaming race that led straight to the fortified water gate of Talo'a.

On the forward deck, the branded executioner was already lunging to recover his footing.

The man was built like an anchor-smith, wide in the shoulders and low to the deck. His cropped scalp showed the jagged brand of the inner tribunal, white scar tissue burned over blue ink. He gripped a heavy, double-edged skinning knife with an iron ring pommel, his body sinking into the low, coiled stance of a third-tier Po'ulu fighter.

Hinalo met him at the cabin bulkhead.

The tracker's iron glaive struck in a tight, arcing sweep, the blade whistling through the spray. Steel bit into iron with a shriek that echoed off the river bluffs. The shock sent a spray of orange fire skittering across the wet cedar planks, but Hinalo's boots slipped on the slick river slime. His chest heaved with a sharp, rattling gasp, the swollen purple meridian along his collarbone darkening under the strain of holding his internal breath.

"The tiller, Ma'uka!" Hinalo barked between clenched teeth, parrying a savage backhand slash that gouged a white furrow through the cedar hatch frame. "Take the helm or we break on the first gravel bar!"

Ma'uka did not wait for a second warning.

He threw himself across the pitching stern deck, his wet boots finding purchase against the raised coaming of the rudder well. The heavy cedar tiller was whipping violently from port to starboard, bucked by the ferocious drag of the river against the steering blade. Each thrash of the heavy timber arm threatened to shatter the wrist of anyone fool enough to grab it barehanded.

Ma'uka unhitched the bronze-tipped pry-bar from the emergency locker beneath the transom. Dropping his weight across the lever, he jammed the iron wedge between the tiller arm and the starboard guide-block.

The wood groaned. The pry-bar bit into the oak cheek.

With a grinding shudder that rattled through his ribs, Ma'uka threw his entire body against the lever, pinning the tiller three degrees off center.

The cutter answered. Her bow swung through the foam, shearing away from the jagged black fang of an eddy-rock that flashed past their port quarter by less than an arm's length. The bow wave threw a wall of grey water across the foredeck, burying both fighters to their knees.

The executioner used the wash. He dropped under Hinalo's guard, driving the heel of his palm toward the tracker's sternum.

It was a classic Po'ulu concussive strike, designed to rupture the lung vessels of an opponent whose breath was already compromised. Hinalo twisted his torso aside, taking the blow on his leather pauldron, but the impact sent him crashing into the port rail. The tracker coughed violently, a spray of dark, clotted fluid spattering the wet timber as his breath locked in his throat.

The assassin stepped forward to finish the kill, raising the skinning blade high.

Ma'uka looked from the helm to the stern mooring line.

When the executioner had severed the boat's lines at Pier Four, he had cut the bowline clean, but the thick hemp stern hawser had snagged around the bronze quarter-cleat. A twenty-foot coil of heavy, waterlogged rope lay heaped against the scuppers, its bitter end anchored to the iron capstan pin.

Ma'uka did not possess the martial cultivation to trade blows with an inner-tribunal enforcer. What he possessed was an exact memory of Section Nine of the Inland Carriage Safety Edicts, which mandated that all towing tackle carry a breaking strain of forty minas under sudden mechanical shock.

Ma'uka hooked the tip of his pry-bar under the free loop of the hawser, flicking the heavy hemp rope across the slick planks directly behind the assassin's trailing heel.

"Hinalo! Down!" Ma'uka shouted.

Hinalo dropped flat against the deck.

The executioner drove forward in a lunging thrust. His right foot caught inside the wet bite of the trailing bight.

At that precise second, the Puna'u Runner plunged through the first chute of the upper rapids. The stern dropped three feet into a boiling trough of white water, and the sudden drag of the river caught the loose coils of hemp hanging over the quarter, snapping the hawser taut against the iron capstan with the violent crack of a bowstring.

The tightening loop whipped around the assassin's ankle.

The sheer momentum of the sixty-ton cutter ripped the man's footing from beneath him. The assassin flipped horizontally in midair, his knife flying into the dark current. His shoulders slammed into the cedar gunwale with a dull crack of breaking bone, and before he could find purchase with his clawed hands, the rushing river sucked the rope and the man over the side.

A brief thrash of white foam marked where he vanished into the dark turbulence of the wake.

Ma'uka stood over the rudder well, his forearms burning with lactic fire as he fought the tiller. "Is he gone?"

Hinalo pulled himself up by the cabin coaming, his left hand pressed hard against his ribs. His breathing sounded like dry husks grinding in a mortar. "Gone to the gravel beds at the bottom. But you took your time about it."

"I had to wait for the stern to enter the draw," Ma'uka said, leaning his weight against the tiller to hold their heading down the center of the froth. "If I tripped the line early, the slack would have fouled the rudder pin and broached the vessel."

"Of course," Hinalo rasped, wiping a smear of dark blood from his chin with the back of his sleeve. "A dead clerk is useless, but a fouled rudder is a regulatory violation."

"An uninspected wreck on an imperial waterway carries a thirty-mina fine," Ma'uka replied, his eyes fixed on the roaring channel ahead. "The guild would have impounded our corpses for salvage fees."

·  ·  ·

The canyon deepened.

On either side of the Puna'u River, sheer cliffs of black basalt climbed two hundred feet into the night fog, shutting out the stars. The water here did not merely run; it dropped through a succession of stepped shelves, the roar of the rapids amplifying between the stone walls until the sound vibrated inside Ma'uka's teeth.

Ahead, where the gorge bent sharply to the south, three glowing points of colored light cut through the drifting vapor.

Two amber lanterns hung from the cliff face on heavy iron cranes. Below them, suspended from a timber gantry forty feet above the boiling current, burned a single lantern of deep green oil.

The signal lanterns of the Talo'a Water Gate.

Ma'uka felt his grip tighten on the cedar tiller. The decoded dispatch in his satchel had named those exact lights: Signal lanterns must show two amber lights and one green to authorize lethal ballista fire across the channel.

"Hinalo," Ma'uka called over the roar of the water. "Look at the gatehouse gantry."

Hinalo moved to the starboard rail, narrowing his eyes against the driving spray.

Across the narrowest pinch of the gorge, a massive boom of iron-bound cedar logs stretched from cliff to cliff, locked in place by heavy forged chains that vanished into the stone counterweight towers on the western bank. Behind the boom, mounted on reinforced timber platforms jutting from the rock, four heavy siege ballistas were trained directly on the center channel, their thick steel-tipped bolts already drawn to the catch.

Beside the gatehouse pier, a long, black-hulled pursuit skiff was already pushing off into the current.

The craft was half the length of the Puna'u Runner, but it carried twelve oars and a heavy bronze ram shaped like a boathook at the prow. A squad of six tribunal enforcers stood on the foredeck, holding iron grapnels and long poleaxes.

"They were waiting for us," Hinalo said, his voice tightening. "The gate boom is dropped. We cannot ram that timber with our hull; cedar will shatter against iron strapping like dry gourd."

"The boom is counterweighted," Ma'uka shouted back, calculating the speed of their drift against the approaching gorge wall. "Look at the water level against the sluice gates beneath the eastern tower. The river is at three-quarter flood. Under Chapter Seven of the Waterway Fortification Code, a flood-stage river boom must maintain a six-foot safety relief gap at the eastern sluice to prevent hydraulic pressure from tearing the winch towers out of the rock."

"A six-foot gap?" Hinalo looked at the churning boil of white foam near the cliff base. "Our hull is eight feet wide at the beam!"

"The hull is eight feet wide," Ma'uka agreed. "The pursuit skiff is five feet."

"How does that help us?"

"The skiff intends to board us from the port quarter to drive us into the center channel where the ballistas have clear line of sight," Ma'uka said. "The decoded dispatch gave us the recognition signals for Central Secretariat couriers. If we change their signal sequence, the shore crews will hesitate."

Ma'uka reached for the signal lantern box mounted beside the steering well.

Inside were four glass lens plates: amber, red, blue, and white. He pulled the standard white lens from the stern lantern and slotted the blue plate into the brass housing, then reached up and hauled the signal halyard.

The blue lantern rose to the top of the short cedar mast.

High on the cliffside gantry, the ballista crews paused. A lookout shouted something that was lost in the thunder of the water, pointing at the blue light. The heavy winch cranks stopped turning. In the bureaucratic hierarchy of the Wai'ata Order, a blue signal light denoted an unbonded courier carrying an internal audit quarantine writ, which carried an automatic twenty-stroke penalty for any gatekeeper who fired without a written counter-order from the Secretariat.

"That gives us thirty seconds of confusion," Ma'uka said. "Now we deal with the skiff."

The twelve-oared pursuit craft was closing fast, cutting across the current at a sharp diagonal.

On its bow, an enforcer swung a heavy three-pronged iron grapnel in a wide circle, waiting for the gap between the hulls to close to twenty feet. The bronze ram at their prow gleamed under the torchlight, aimed directly at the Puna'u Runner's steering rudder.

"Hinalo! The bow capstan!" Ma'uka yelled. "Release the pawl on the heavy kedge anchor, but do not drop the flukes! Keep the cable snubbed around the drum with one turn!"

Hinalo did not ask why. Despite the agony in his chest, the tracker vaulted over the cabin roof and landed by the bow winch. With two swift kicks of his iron-shod boot, he knocked the heavy locking pawl free. The thick iron fluke of the fifty-pound river anchor hung suspended over the bow stem, held only by the tension of the hemp cable wrapped once around the bronze winch drum.

"Ready!" Hinalo shouted back.

The pursuit skiff surged alongside.

"Hold your oars and drop your sail in the name of the Grand Inquest!" an enforcer roared from the skiff's bow, hurling his grappling iron.

The four-pronged hook flew through the mist, biting deep into the Puna'u Runner's port bulwark with a violent crunch of splintering wood. The trailing braided hawser snapped taut, binding the two vessels together in the roaring current.

Two more grapnels slammed into the cabin roof. The enforcers on the skiff hauled hard on the lines, drawing the lighter pursuit boat flush against the Puna'u Runner's side. Three armed men leaped across the gap, their short swords drawn, boots hitting the deck.

Ma'uka held the tiller steady, steering directly toward the raging eastern sluice where the boiling white water poured through the narrow gap beneath the cliff tower.

"Hinalo! Drop the anchor!" Ma'uka bellowed.

Hinalo kicked the snubbed cable free.

The fifty-pound iron kedge anchor plunged into the river, vanishing into the black froth directly ahead of the bow.

The heavy cable hissed as it screamed off the drum, smoke rising from the dry hemp.

Fifty feet down, in the narrow hydraulic throat of the eastern sluice, lay the submerged timber cribbing and stone anchors that stabilized the gatehouse foundation. The iron flukes of the falling anchor caught violently in the submerged timber network.

The Puna'u Runner shuddered as if struck by a falling cliff.

The bow dipped violently, throwing a three-foot wave across the foredeck. But Ma'uka had already locked the tiller hard to starboard. The sudden, ferocious drag on the anchor cable acted as an immense mechanical pivot, swinging the stern of the heavy cutter through a violent sixty-degree arc.

The pursuit skiff, lashed tight to the cutter's port flank by three taut grappling lines, was caught on the outside of that arc.

The centrifugal force and the immense hydraulic suction of the sluice channel dragged the lighter boat sideways across the river.

The enforcers who had boarded the cutter lost their balance as the deck tilted thirty degrees. One slipped on the wet cedar and tumbled overboard into the boiling foam; Hinalo swept the legs from the second with the blunt haft of his glaive, sending him crashing into the scuppers. The third turned to flee back to his vessel, but it was already too late.

The skiff was wrenched directly into the massive, moss-covered basalt pilings of the weir.

With a sound like the detonation of a siege charge, the pursuit boat's cedar hull struck the stone foundation. The entire craft buckled in the middle, its frames splintering into jagged firewood under the combined force of the river's rush and the cutter's leveraged weight. The screams of the oarsmen were swallowed by the roar of the water as the wreckage was sucked beneath the timber gantry.

The three grappling hawsers holding the skiff to the Puna'u Runner snapped one after another with the concussive cracks of whip-strikes, the frayed ends lashing the river fog.

"The cable!" Ma'uka screamed, fighting the tiller as the cutter pivoted toward the locked boom. "Cut the anchor cable or we will follow them down!"

Hinalo raised his iron glaive with both hands.

Drawing upon the last reservoir of his physical strength, the tracker brought the heavy blade down in a single, devastating chop across the bronze winch drum. The severed hemp cable parted instantly, whipping through the hawsehole and vanishing into the deep.

Freed from the anchor's drag, the Puna'u Runner surged forward on the crest of the sluice wave.

The narrow six-foot relief gap beneath the eastern tower loomed directly ahead. The iron-bound cedar boom sat two feet above the water line, vibrating under thousands of tons of river pressure.

The cutter's bow struck the weakest point of the boom where the timber joined the sluice relief gate.

Copper-plated mountain cedar met waterlogged pine.

The impact tore through the hull with a deafening screech of ripping copper and groaning wood. The heavy boom groaned, its rusty hinge pins shearing under the violent wedge of the cutter's forward momentum. The cedar logs of the barrier buckled downward, snapping their retaining chains in a shower of sparks that rained across the deck.

The Puna'u Runner scraped over the submerged wreckage, her bottom planks grinding over the broken logs, and shot through the breach.

Behind them, the high ballista bolts finally discharged, thudding into the foaming water fifty yards astern where the pursuit skiff had vanished.

The narrow canyon walls fell away.

The roaring funnel of the Talo'a gorge opened into the wide, black expanse of the lower Puna'u river basin. The violent white water smoothed into a deep, swift current that carried the battered cutter out onto the open river, under the quiet, mist-laden sky.

·  ·  ·

The sudden silence of the open water was louder than the rapids had been.

The Puna'u Runner drifted down the center channel, her copper-plated prow scored with deep silver gashes from the gate chains, her port rail shattered where the grapnels had bitten. The mist hung low over the flat river valley, smelling of wet reeds, sweet marsh mud, and cold mountain silt. Five miles downstream, the dark water wound toward the great coastal lowlands, far beyond the reach of the Talo'a gatehouse ballistas.

Ma'uka tied off the tiller with two turns of braided hemp, locking the rudder in the middle groove. His hands were shaking, the skin of his palms raw and blistered from the vibrating wood.

Hinalo sat slumped against the foredeck capstan, his head resting against the cold bronze drum.

The tracker's glaive lay across his knees. His breath came in shallow, fluttering wheezes, each exhalation accompanied by a wet, bubbling sound deep in his chest. His fingers were stained with dark, coagulated blood that had dried black in the river wind.

"We cleared the gate," Hinalo murmured, his eyes half-closed. "Tell me you logged the damage to the boom in your ledger, Clerk. It would be a pity to commit river piracy without a receipt."

"The gatekeeper failed to display the statutory red inspection beacon before drawing the ballista winches," Ma'uka said, walking stiffly down the pitching deck. "Under Section Fourteen of the Harbor Defense Code, a civilian vessel clearing an unmarked hazard during flood stage is exempt from barrier indemnities. The damage is chargeable to the Talo'a municipal garrison."

Hinalo let out a dry, cracked sound that might have been a laugh. "I am sure Overseer Toru will send them a letter of condolence."

Ma'uka stopped beside the cabin hatch.

The heavy iron gaff-hook that the branded assassin had driven through the slide ring was bent double, jammed tight into the bronze latch.

Ma'uka took his ivory-handled folding knife and the bronze pry-bar. Wedging the iron tip beneath the gaff's shank, he leveraged his shoulder against the bulkhead. With a sharp metallic crack, the deformed bronze ring sheared away, and the wooden hatch slide rolled back along its track.

Ma'uka stepped down the two cedar steps into the low cabin.

The space smelled of damp wool, cedar oil, and the sharp, iron tang of freshly spilled blood.

Pili'a lay sprawled across the floorboards between the two sleeping bunks. The woolen quilts had been kicked aside. His grey linen tunic was soaked through at the collar with thick, dark crimson fluid that had pooled in the hollow of his throat and dripped onto the rough floorboards. His face was the color of wet river clay, his lips tinted a pale, bruised violet.

His eyes opened slowly as Ma'uka knelt beside him.

"Ma'uka..." Pili'a whispered. The voice was barely a thread of sound, rasping over the ruined tissue of his windpipe.

"Do not speak," Ma'uka said, reaching for his master's wrist.

The pulse beneath the skin was irregular and violent, fluttering like a trapped moth. The lung meridian along Pili'a's forearm felt cold and hard, the tissue beneath the skin knotted into rigid cords of stagnant energy.

The accelerated transfer docket had not been an idle threat. Elder Rongo'u's couriers had already administered a slow-acting metabolic catalyst before Pili'a was ever moved from the Fale'a holding cells, designed to ensure that the mentor's Po'ulu rot would reach its terminal stage forty days ahead of the statutory inquest date. The violent shock of the river descent and the damp river cold had accelerated the collapse.

If they stayed on the water for another three hours, Pili'a's lungs would drown in his own clotted blood before dawn reached the delta.

"The... the cipher..." Pili'a breathed, his trembling fingers clawing at the rough floorboards. "Did you... find the numbers?"

"I have the cipher plate," Ma'uka said gently, pulling the dry wool quilt over his mentor's trembling chest. "I have the Casualty Roll. And I know what Rongo'u ordered for the Ko'ko shafts."

Pili'a closed his eyes. A single shudder passed through his wasted frame.

Hinalo's shadow fell across the cabin threshold. The tracker leaned against the hatch frame, his dark eyes taking in the blood on the floor and the rattling rise and fall of the old man's chest.

"He will not survive the night on this boat," Hinalo said quietly.

"No," Ma'uka said.

He stood up, looking past Hinalo toward the wide, dark river stretching into the mist.

Three hundred yards ahead on the western shore, the low reeds gave way to a broad, sheltered mud bank where an old willow grove leaned out over the water, sheltered from the river patrol by a high wall of river clay.

Ma'uka reached for the wooden satchel containing the cipher plate, the casualty rolls, and the jar of pao-root tincture.

He turned back toward the helm. There was no time to reach the delta port, and no margin left to play the law against the garrison. He took the tiller, untied the hemp lashings, and threw his weight against the wood, steering the battered cutter out of the main channel and into the dark shadow of the western mud bank.
