The Sump Ambush

The grease coating the Fourth Arterial Confluence carried the stink of boiled marrow and alkaline lye through every seam in the brickwork. Commander Malmkar crouched against the slime-slick vault, scarred palms flat on vibrating conduit iron. He needed a municipal lineman before midnight. With his sapper Jorund dead behind Slag Hopper Four, the planned strike at the covered market was an empty gesture without someone carrying brass clearance keys to Substation Nine. Killing soldiers was simple; finding a technician who could open the high-voltage oil drains was the only way to blind the district.

Fifty paces to his left, down the drain toward the rendering vats, three sheared projections of his scouts stood on a rotting gantry under an iron storm grate. Their phantom figures shifted, adjusted straps, and leveled carbines into sulfurous haze, entirely empty of blood or bone.

A low mechanical thrum vibrated through sewage. An Echelon patrol skiff slid up the canal, twin props churning oily water into gray froth. Malmkar had severed line monitors upstream to draw this escort out, clearing the channel so his fighters could snare the repair crew following behind it.

"Hold the valves," Malmkar whispered. Beside him in the alcove, Vardmar gripped the pull-wire of the ignition line, his breath rattling through a cracked filter mask. Their physical bodies remained cold and still in dark water, fifty meters removed from the decoys painted against the grate.

The Echelon skiff cut its props thirty paces short of the gantry. A searchlight flared atop its gun shield, throwing three thousand lux of white beam across the wooden platform. The three sheared phantoms did not flinch; the beam merely sharpened their edges against dripping masonry.

The patrol commander issued no challenge. A rotary gun on the skiff opened up with a deafening hammer. Flechettes chewed through decking, kicking up geysers of wet splinter. Rounds tore straight through the chests of the three projected shapes. The phantoms flickered as water spray scattered ambient light, but remained upright, hollow and indifferent to the steel tearing planks behind them.

Malmkar wiped lye spray from his lip. "Dumb bastards. Three hundred flechettes into sewage pipes, trying to drown ghosts."

He raised his left hand, scarred flat where an old grid arc had burned away his ear, and snapped his fingers downward.

Vardmar yanked the pull-wire.

Ten paces behind the Echelon skiff, two glass jugs of refined transformer oil shattered against the iron hull. A friction match sparked inside the conduit neck. Orange flame leaped across the greasy film on the water, engulfing the skiff's stern and cooking off flare cartridges. The searchlight jerked toward the ceiling, painting vaulted brick in wild circles before the skiff capsized, hissing as foul water swamped the hot engine casing.

"Clear the canisters," Malmkar ordered. "Save the filters."

Vardmar whistled through his teeth. The sheared projections on the gantry blinked out as battery leads were disconnected, collapsing ionized gas fields into wisps of sweet almond exhaust.

Before echoes died in the tunnel, a second sound drifted from the northern intake: the scrape of a municipal maintenance punt bumping against iron pilings.

Malmkar pulled a copper-weighted snatch net from the wall peg. "That will be the repair call. Dispatch flagged the surge from Pylon Forty-Four. They are running a lineman down the grease pipe to check return cables."

A flat-bottomed punt drifted into the fringe of the sodium beam. In the center stood a technician in oil-stained overalls, holding a brass voltmeter in one hand and an insulated grounding wand in the other. His canvas jacket was ripped at the shoulder, his face gray with fatigue.

"Take him," Malmkar said.

Vardmar and two fighters leaped from darkness. The snatch net came down over the punt with a wet slap of cord. The technician yelled as his meter clattered against wet floorboards, but heavy boots pinned his shoulders to timber before he could swing the wand. They hauled him into the disused regulator vault behind the dry sewer sluice.

They dropped him onto slime-slick flagstones. Vardmar stripped the lineman's canvas jacket, reached into the torn breast pocket, and jerked out a folded work pass along with a damp slip of yellow paper. He passed both to Malmkar before kicking the tool pouch aside.

Malmkar stood over the prisoner, letting the yellow glare of a caged lantern wash across the documents. The technician lay panting, fingers trembling where fresh copper flash-burns darkened his knuckles.

"Lineman Einarund," Malmkar said. "Depot Nine. You took your time answering the conduit fault."

Einarund pushed himself up against wet brick, clutching his bruised shoulder. "I am municipal service," he rasped, coughing as noble gas caught in his throat. "Standard ground-check. The Directorate seals the sector if the return bus trips."

"The Directorate seals the sector because they fear what lives under their boots," Malmkar said. "Don't recite bylaws to me. You grounded Pylon Forty-Four because an Echelon shear-stalker tried to gut you on the service ladder."

Einarund kept his eyes on Malmkar's scarred cheek, offering no reply.

"You smell of solvent," Malmkar said. "And transformer grease. You pulled a cylinder off Forty-Four, didn't you? A lineman doesn't short a high-voltage bus without salvaging the evidence. You know what hunters carry. You know what they do to crews who see too much."

"I know nothing about hunters," Einarund said. "Foreman Torvalund signed the voucher. Vibration wear. If I don't return with the logbook stamped, the audit squad—"

"The audit squad already has your scent," Malmkar cut in. He tossed the yellow paper back onto Einarund's lap.

The paper was damp, but the red Directorate stamp remained sharp: a medical air-ration notice from the Public Health Directorate.

Einarund stared at the slip, his breathing shallow.

"Helgund," Malmkar said. "Tenement block four, fourth sub-level. Sump-cough. Silicosis. One hundred and forty scrip in arrears for scrubbed oxygen. The Echelon granted a seventy-two-hour stay this morning, didn't they? Warrant Astridsk stamped it with her own seal."

Einarund looked up, knuckles pressing white against concrete. "How do you know what Astridsk signed?"

"Nothing moves through Depot Nine without passing through hands that answer to me," Malmkar said. "Jorund was my sapper. You worked alongside him for three years, checking transformers while he plotted feed lines for my cells. Now Jorund has three flechettes in his spine behind Slag Hopper Four, and you walk out of the security booth with a temporary pardon."

"I didn't give them Jorund," Einarund whispered. "I didn't say a word about him."

"It does not matter what you said," Malmkar leaned closer, the scent of stale tobacco and ozone rolling off his collar. "What matters is what you do tomorrow morning. At seven hundred hours, the shift change begins at the covered market. The Directorate is flooding the stalls with plainclothes hunters to root out my couriers."

Malmkar pulled a grease-stained blueprint from his tunic and slapped it against an old condenser unit. His blackened finger tapped a square marked with a lightning bolt.

"Substation Nine sits directly above the market arcade," Malmkar said. "Its step-down bank holds three thousand gallons of cooling oil. You take your pass, climb the pylon stairs, and open the drain petcocks on the reserve tank. Then bridge the busbar with a copper jumper."

Einarund's face drained of color. "That blows the entire bank. The oil atomizes into vents, creating blinding fog across three blocks. The voltage plunge kills the streetlights."

"It drops the sector to zero lux," Malmkar said. "When light dies, every optical shear in Sector Nine snaps shut. Hunters won't hide behind phantoms. Their searchlights die. My people butcher every gray coat in that plaza before emergency generators kick in."

"There are four hundred market vendors in that hall," Einarund said. "If transformers detonate, the oil fire drops down the vents. It incinerates half the arcade."

Malmkar seized the front of Einarund's canvas shirt, twisting the collar until the technician choked.

"Then pray vendors run fast when sparks fly," Malmkar said. "Because if you don't drop those busbars at seven hundred hours, I will send a runner to the Hunter Corps garrison. I will tell Warrant Astridsk to tear up your workbench for contraband noble-gas ordnance. And I will tell her that your sister Helgund has been housing dissident couriers in her cellar since winter thaw."

Malmkar shoved him backward against the damp wall.

"They will cut her air lines before noon, Einarund. She will choke on her own lung fluid while you sit in an interrogation chair. You have eight hours. Burn the glass to find the iron, or watch your sister suffocate under Directorate law."

Malmkar reached down and unhooked the brass ring of master keys from Einarund's belt, weighing them in his palm before slipping them into his coat pocket. "I keep the substation keys. If you want them back to reset the breakers before your foreman notices, you meet me at the arcade gantry."

He turned to Vardmar. "Give him his meter. Put him back in his punt and shove him down the northern conduit. If he turns around, put a slug through his lungs."

Malmkar stepped out onto the catwalk, listening to the splash of oars fading into the dark drainage run. Far above the brick vault, the muffled pulse of the city's sodium grid pressed through stone, counting down the hours until morning.
