The yellow dawn broke over Ward 9 with the sickly tint of sulfur smoke, damp coal dust, and curdled animal fat.
Arthur Vance stood on the outside platform of the clinic’s sixty-foot brick chimney pipe, his field boots resting on the wet iron grate. The November drizzle had ceased an hour before sunrise, replaced by a cold, clinging mist that hugged the slate roofs of the slums. Down in the drainage under-road drains that carried wastewater from the high-tier Academy laboratories into the town canals, the runoff was not its usual greasy black.
It was glowing.
A faint, eerie-glowing turquoise sheen danced on the surface of the sluggish water, emitting plumes of dense, yellowish-white vapor that smelled of scorched petroleum, bitter almonds, and man-made fluorinated esters.
Beside Arthur, Grimm stood rigid on the platform, his black neck ruff bristling into stiff spikes. The jet-black hound didn’t sniff the air. He exhaled a sharp, defensive snort. He curled his upper lip to seal his smell passages against the acrid chemical vapor. A low, warning shaking hummed in his chest. That made the iron railing beneath Arthur’s hands hum in sympathetic deep ring.
Beneath them in the courtyard, Barnaby the burrow-hog suddenly sneezed. The three-hundred-pound beast backed out of his straw nest beneath the lean-to, shaking his broad snout and rubbing his rubbery jowls against the brick foundation, refusing to touch his morning trough of clean water.
Arthur raised his left hand, adjusting the sight dial of his Zeiss-Vanguard Monocle Loupe.
The quartz prisms lined up with a sharp snick. Amber tracking data scanned the drifting yellow haze:
Arthur’s jaw tightened into a rigid line.
“That isn’t fire exhaust,” Arthur murmured into the cold morning air. “That’s heavy-duty bio-alchemy waste. They’re flushing the upper testing labs straight into the slum under-road drains.”
Before Arthur could climb down the iron ladder, a wild chorus of howling erupted from the lower avenues of Ward 9.
It wasn’t the aggressive baying of street hounds defending territory or fighting over slaughterhouse offal. It was the shrill, painful yelp of animals in total breathing distress. A sound that Arthur recognized from his years in emergency trauma wards.
Arthur hit the flat stone slabs of the courtyard in three strides.
“Toby!” Arthur shouted, throwing open the clinic double doors. “Boil three kettles of underground water bed water! Bring out the activated charcoal canisters, the gastric escape tubes, the atropine vials, and every clean wool blanket in the loft! The town drainage water gates have been poisoned!”
Toby Mallow scrambled out of the office, his wire-rimmed glasses askew, purple dark oak-ink still wet on his fingers. “Poisoned? By what?”
“Man-made heavy-duty runoff,” Arthur said, strapping on his oilskin razor-sharp apron. “And it’s spreading through the street drinking fountains.”
Within fifteen minutes, the clinic courtyard transformed into an emergency battlefield triage ward.
Desperate commoners flooded through the iron gates by the dozens: coal wagon drivers, canal barge draymen, night-soil sweepers, and tenement mothers carrying family watch-dogs in their arms. Men with faces blackened by fire soot were weeping openly. They grabbed shivering terriers and heavy draft mastiffs whose limbs were locked in violent, rhythmic convulsions.
“Master Vance! Help him, please!” a coal hauler shouted, laying an eighty-pound brindle cart-hound onto the zinc check table. “He just took two laps from the public fountain by Gate Four! He started shaking, and then... Look at his mouth!”
From the dog’s nostrils and black lips bubbled a thick, thick, sticky foam. Not the frothy pink slimy of congestive heart failure, but a vivid, rainbow-bright cobalt-blue gel that clung to the animal’s whiskers like man-made varnish.
The dog’s eyes were rolled back, showing bloodshot white of the eye, its ribs heaving against rigid deep-belly spasms.
Arthur leaned down with his brass stethoscope metal tube. He pressed the bell against the dog’s chest wall.
The sound through the earpieces was terrifying. No vesicular murmur, no moving air, only a high-pitched, whistling friction rub like wet leather stretched over hot iron.
“Acute toxic lung fluid swelling,” Arthur diagnosed, his hands moving with cold, clockwork speed. “The chemical is a man-made surfactant. It dissolves the natural rich fat barrier in the lungs, causing immediate tiny blood vessel leakage into the lung-sac sacs. The fluid polymerizes on contact with sky oxygen, creating an airtight gel that suffocates the animal from within.”
“Can we pump the stomach?” Toby asked, rushing over with a wide-bore rubber tube and a bucket of warm saline.
“The stomach is already evacuating,” Arthur said. He pointed to the blue bile pooling on the zinc tray. “The mucosal absorption was instant. We need to clear the upper airway, administer under-skin atropine to dry the lung secretions, and give packed activated charcoal to bind whatever remains in the gut.”
Arthur worked without pause.
He threaded a brass hollow tube down the mastiff’s throat pipe, attaching an eight-ounce copper suction syringe. He hauled on the plunger with steady pressure. He drew out thick plugs of the tacky blue gel to clear a narrow air channel. Meanwhile, Toby injected five drops of belladonna extract into the dog’s flank to halt the lung spasms.
Around them, forty more animals lay groaning in the straw pens.
In pen two, Kael was kneeling beside a five-year-old heavy cart mare that was trembling wildly, her knees buckling as blue froth dripped from her nostrils. Arthur ran to the pen, performing an emergency transtracheal catheterization with a twelve-gauge needle, flushing the upper throat pipe with cold saline to break the water’s skin and applying an ice-water compress over the larynx to reduce the inflammatory swelling.
Beside the gate, a seven-year-old girl in a frayed wool shawl sat on a timber crate, sobbing wildly as she clutched a tiny scruffy terrier whose paws were twitching in reflex spasms.
Barnaby the burrow-hog waddled out from beneath the lean-to. The massive swine approached the weeping child with slow, delicate steps, lowered his broad snout. Then he gave her knee a soft, warm nudge. That let out a sympathetic, deep-throated snort that coaxed a watery smile from the girl.
“Toby, organize a bucket brigade!” Arthur shouted across the noisy hall. “Kael, take four men to our well pump! Flush the public water trough in front of the gate with fresh underground water bed water! Tell every wagon driver in the ward not to let their animals drink from the street under-road drains!”
Toby ran to the gate with a roll of litmus paper and a dropper bottle of silver nitrate. It tested the water in the street ditch. The paper turned an intense, bitter-salt purple. Meanwhile, the silver nitrate formed a heavy white curdy precipitate that refused to dissolve.
“Arthur!” Toby shouted back. “Heavy fluorinated salts in the street runoff! The concentration is high enough to corrode tin pipe!”
In the center of the crowded courtyard, Grimm acted as an anchor of calm.
The jet-black hound didn’t pace or bark. He moved step by step between the crowded pens, his heavy, solid body brushing against the legs of weeping wagon drivers, offering an unmoving physical brace. A panicked owner stumbled backward toward the zinc tables. Each time, Grimm set his broad flank behind their knees, steadying them with quiet hunting beast power.
In pen three, a scared terrier pup was thrashing against the timber slats, choking on blue foam. Grimm lowered his massive black head, sniffed the pup’s trembling ear. Then he let out a single, deep, sub-heard chest shaking. The pup stopped thrashing, pressing its shivering muzzle against Grimm’s solid black foreleg, calmed by the overwhelming magnetic presence of the apex hound.
By noon, Arthur and Toby had steadied eighteen animals. But their supplies of atropine, charcoal, and clean saline were virtually exhausted.
Arthur stood over the zinc sink, his arms stained to the elbows with blue bile and carbolic suds. His breath came in ragged, tired puffs as he washed his razor knife.
“Arthur,” Toby whispered, leaning against the timber partition, his face pale with tiredness. “We’ve used forty bottles of charcoal. The apothecary supplies in Ward 9 are fully empty. And more carts are pulling up outside. If we don’t find a chemical neutralizing agent for that blue gel, half the working beasts in this district will be dead by nightfall.”
Arthur adjusted his monocle. He stared at a smear of the cobalt residue on a glass slide.
“Standard beast-doctor reagents can’t break down a fluorinated ester,” Arthur said. His eyes were cold and dark. “This wasn’t brewed by slum alchemists. This is military-grade high-polymer chemistry, engineered in the upper research laboratories of the Academy.”
Arthur stripped off his rubber gloves, throwing them into the wash basin.
“Someone flushed an entire heavy-duty batch into the town chimney pipes to bury evidence,” Arthur continued. “And there’s only one way to stop it: we need the exact atom-deep codon.”
Outside, wild footsteps splashed through the mud.
The clinic door flew open. Old Man Corvin stumbled over the threshold, cradling his unconscious eighty-pound sump-mastiff Burl in his scorched leather apron, weeping into the coal dust on his sleeves.
The necropsy was about to begin.
