Hoarfrost crawled backward along the trench floor toward the black shape, drinking the damp out of the clay until the soil turned to gray pumice. Dorottya Illyési knelt two paces back from the frost margin, her vulcanized apron stiffening against her knees. She needed the pilot torch spitting clean blue within ninety seconds, or the creeping sinkhole would freeze the bronze reduction valve on her lance before the line could prime.

Across the dogleg of Sector 9, pine revetment posts groaned under sudden expansion. Cold did not merely settle here; it pulled. The silhouette stood upright in the middle of the duckboards, a man-shaped void of pure absorption that swallowed the pale afternoon light without casting a shadow of its own. Three hours ago it had been an infantry runner taking a shell fragment through the throat. Now it was a standing sinkhole, drawing caloric life out of the earth at twenty paces and petrifying the surrounding air into an unbreathable crawl.

Behind her, iron runners screeched against iced gravel. Gyurka Szelényi dragged the twin-cylinder propellant sledge around the traverse, his shoulders hunched inside a sheepskin coat smeared with tallow and graphite. He dropped the tow harness into the mud and kicked the timber wheel chocks into place.

"Manometer says thirty-two atmospheres on the booster bottle," Gyurka said, wiping black grease from his chin with the back of a woolen mitten. "Siphon feed is thickening up like lard in an unheated pantry. If we stay squatting in this cellar another five minutes, you'll be scraping the starter paste out of the tube with an oyster knife."

"Coupling collar first," Dorottya said. She did not look back. Her gloved fingers traced the braided copper lead running from the sled to the manifold at her hip. "Check the leather washer on the return bypass. The last tender left tallow on the thread, and the cold turned it to bone."

Gyurka knelt by the valves, his heavy breath blooming in thick, curdled puffs before the black hull drank the moisture straight from the air. "I saved two spoonfuls of salt pork fat from breakfast to grease the threads. Real lard, mind you, not that boiled hoof oil the depot issues for gun axles. Waste of good calories. A man could fry turnip shavings in that fat, but no, we burn it to keep bronze valves from snapping."

"Lard burns foul in the secondary jet," she said.

"Everything burns foul out here, Chief. The war just hasn't noticed yet." He spun the spanner, metal clinking sharply in the deadened air. The presence of the silhouette muffled sound, flattening the ring of steel into a dull thud. "Bypass collar is seated. You have pressure on the dial."

Dorottya lifted the eight-foot lance, settling the brass counterweight into the crook of her shoulder. The weapon weighed forty pounds dry, sixty with the twin tubes primed. She checked the bronze petcock at the burner neck. When she nudged the valve open with her thumb, the feed hissed, sputtered, and died.

A clog. Not ice in the tank, but a crust of calcined carbon lodged inside the pre-heater baffle from yesterday's second burn.

She closed her eyes against the sting of freezing sleet, pressing her cheek against the cold brass receiver. She clicked the bypass hammer twice with her knuckle, listening through the metal casing. A hollow ping, followed by a dry rattle like lead birdshot rolling inside an empty kettle. The baffle flap was frozen half-shut, choking the pilot jet before the phosphorus paste could atomize.

"Give me the copper wire," she said.

Gyurka fished a length of stiff, flattened wire from his chest satchel and slapped it into her palm. "Work fast. The duckboards are silvering over. My boots are sticking to the timber."

The white crust of frost was advancing by inches, creeping across the hemlock boards like spilled milk. The cold radiating from the silhouette pressed against her chest, tight and dry, carrying that particular metallic reek of photolytic decay—not rotting flesh, but the stale, ozone bite of lightning striking stagnant pond water.

Dorottya seated the lance against her hip, unscrewed the brass cowl with her bare fingers despite the skin tearing slightly on the freezing metal, and slipped the copper probe into the auxiliary vent. She felt the obstruction with the tip: a hard lump of oxidized slag clinging to the brass seat. She twisted the wire three degrees to the left, caught the edge of the carbon lip, and jerked forward.

The pellet dropped free into the mud.

"Clear," she muttered, snapping the cowl shut and running the locking nut down tight. "Prime the red cock."

Gyurka hauled back on the secondary lever of the sled. A sharp hiss ripped through the delivery hose. Inside the lance's mixing chamber, white phosphorus paste mixed with pressurized nitrate fluid, foaming against the ignition wire.

Dorottya struck the flint wheel with the heel of her glove.

A needle of violet flame snapped to life at the lance tip, snarling against the damp air. The thermal shock made the hoarfrost on the duckboards hiss and recoil, retreating several inches from the roaring nozzle. The pilot was small, barely thicker than a finger, but its core burned at eight hundred degrees, fighting the sinkhole's drain.

"Pressure holding at twenty-eight," Gyurka called out, bracing his boots against the traverse wall. He clamped his hands over his respirator goggles. "Ventilation's bad here, Dorottya. That traverse revetment traps everything. Don't linger on the sweep."

She stepped past the frost line.

The silhouette had no face, no eyes, no uniform insignia remaining upon its surface. The photolytic trauma had collapsed the flesh into a dense, lightless spindle, an upright blot that drank the warmth from her chest with the pull of an open flue. Her breath froze in her throat before it could leave her lips.

Dorottya brought the brass nozzle up, sighting along the alignment rib. She locked her boots into the slime of the trench floor, leveled the lance at the creature's sternum, and kicked the main trigger dog open.

The world vanished in blinding white phosphor.

Twelve hundred degrees of aluminothermic fire erupted from the nozzle in a roaring spear three yards long. The sound was not an explosion, but the deafening roar of a furnace flue torn open to the sky. The blast struck the silhouette dead center.

The black hull resisted for a single, shuddering heartbeat, turning incandescent violet along its edges as its frozen density fought the heat. Then the physics of photolysis broke. The silhouette collapsed inward with a sound like shattering glass, dissolving into an enormous geyser of scalding white steam.

The vacuum struck instantly.

Within five yards, every breath of oxygen was consumed by the chemical jet. The sudden thermal displacement pulled the air straight out of Dorottya's lungs, crushing her ribs like an iron band. Her knees buckled under the violent recoil of the lance. She tasted sulfur, copper, and scorched wool in the back of her mouth, her vision rimmed in dancing crimson spots as she fought the suffocating draft.

She cut the fuel valve, let the lance drop into the mire, and fell forward onto both hands, heaving against empty air until the cold wind spilled back down the trench line to fill the void.

Gyurka scrambled forward through the swirling steam, coughing into his sleeve, and dragged her upright by her collar.

"Breathe, Chief," he rasped, his voice raw. "Breathe. It's gone."

Dorottya dragged the bitter sleet into her chest, coughing until her ribs ached. The white steam was already thinning, drifting up through the pine stakes into the gray sky.

Where the silhouette had stood, the duckboards were charred to black charcoal, steam rising in greasy plumes from the mud. The lethal cold had broken. The air in the traverse was wet and miserable again, returning to the normal, filthy chill of the front line.

"Told you the baffle was sticking," she wheezed, wiping greasy condensation from her cheek.

"You're a genius with a copper rod," Gyurka said, bending down to inspect the scorch circle. "Look at this mess. Slagged straight through to the clay."

He kicked at a brittle lump in the center of the burn.

Dorottya frowned, stepping closer.

A civilian corpse dissolved by photolytic heat left only gray ash and teeth. A soldier left iron belt fittings and rifle barrels. But nestled inside the charred remnants of two disintegrating leather boot soles lay a flat, stamped oval of tarnished iron.

Dorottya crouched and picked it up with her insulated tongs.

The metal was hot enough to scorch the leather pads, but the stamped lettering remained crisp under the soot. It bore the twin-crescent crest of the Cserhát Hegemony, but the numerals beneath were wrong.

Third Reserve Fusiliers. Depot Battalion Seven.

Gyurka leaned over her shoulder, squinting through the sulfur fog. The usual irony drained from his mouth.

"That's rear-echelon," he said quietly. "Third Reserve is billeted thirty leagues south, guarding the grain silos near Nagylak. What is a depot soldier doing taking shell fragments in the traverse of Sector 9?"

Dorottya slipped the hot iron tag into the inner pouch of her sheepskin coat.

"He didn't take a shell fragment," she said.
