Sweeping the Vapour

Countess Shizuka did not blink. A mortal woman would have started, gasped, or reached for a silk robe to hide the crumpled body at her feet. She merely stood by the window, the hem of her dark brocade gown trailing across the Persian wool rug, her breath drifting into the warm air like pale mountain fog.

Around us, the cabin was dead quiet.

\"You took your time with the kettle, steward,\" she said. Her voice sounded like ice sliding over polished slate—cool, resonant, and entirely devoid of human tremor.

\"The third-deck boiler has a leaky gasket, my lady,\" I replied, keeping my eyes fixed politely at the level of her throat. Looking directly into her irises felt like staring into an empty mine shaft. \"The galley took ten extra minutes to bring the water to a rolling simmer. I brought the dried camphor leaves you requested.\"

Behind her, Baron Minato groaned softly. His fingers twitched against the base of the brass radiator, but his eyelids stayed shut. A thin sheen of white rime coated his whiskers, glistening under the amber glow of the gas sconces.

I took two paces to the side, and knelt beside the fallen nobleman.

\"He is not dead,\" Shizuka murmured. She had not moved an inch, yet the temperature in the room plummeted three degrees. \"Do not look so panicked.\"

\"I am not panicked, my lady. I am merely calculating how many minutes we have before Head Stewardess Miyako sends a porter to look for me.\" I pressed two fingers against Minato's throat. His pulse fluttered like a moth trapped under wet parchment. When I drew in a breath through my teeth, the baron's scent was completely hollowed out. Ten minutes ago, in the corridor, Minato had reeked of sour plum wine, rotten card debt, and frantic sweat. Now, nothing remained except the chalky, empty odor of spent ash.

She had eaten his terror down to the marrow.

\"You have an unusual pulse, steward,\" Shizuka said, her head tilting slightly. \"Men who enter this room usually weep. Some offer me jewels. Some try to pray to gods whose shrines rotted five centuries ago. You have not dropped your tray, and your heart beats with the dull cadence of a dockhand hauling timber.\"

\"Panic does not clean carpets, my lady,\" I said.

I reached into the deep canvas pocket of my steward's apron. Alongside the stolen brass passkey I had scooped from the floor moments ago, I kept the standard emergency medical pouch issued to upper-deck stewards. In high-altitude zeppelin crossings, wealthy fools frequently fainted from thin air, rich food, or opium fumes.

I uncorked a glass vial of pungent spirit of ammonia and waved it under Minato's nose. The baron gave a violent shudder, his head tossing against the carpet, but the vacant glaze over his face remained unbroken.

\"Ammonia will not wake a vessel emptied of spirit,\" Shizuka observed. She drifted closer, her movements so fluid that her skirts barely whispered. The scent of her rolled over me in a clean, shock-cold tide: mountain rain, crushed snow, and pure, untarnished copper.

For the first time since my shift began at dawn, the throbbing behind my temples ceased.

Out in the corridors, fifty passengers exuded a sickening broth of deceit, grease, and rotting ambition that felt like rusted needles in my brain. But beside this creature, my overstimulated nerves went completely still. It was terrifying, and it was the closest thing to heaven I had felt in three years aboard the Kurogane.

\"He does not need to wake,\" I told her, keeping my voice clipped and practical. \"He only needs to look like he suffered an altitude convulsion. If Commander Haruki finds an aristocrat drained of his vital essence inside Suite Nine, he will not bother with polite inquiries. He will seal the corridor, pump carbolic gas through your vents, and jettison this entire compartment into the toxic squall.\"

Shizuka's eyes narrowed. \"The purgers have grown quite bold since we left the northern port.\"

\"They have authority over life and death aboard this vessel. Bad air threatens everyone, and Haruki considers anything irregular to be bad air.\"

I grabbed Minato by his velvet lapels and hauled him backward. The baron was a heavy man, weighed down by gold signet rings and an overfed belly, but three years of wrestling freight crates in the steerage hold gave me broad shoulders. I hoisted him onto the velvet settee by the window, propped his head against two tasseled cushions, and unfastened the top three buttons of his brocade waistcoat.

Next came the art of deception. I dabbed a drop of eucalyptus oil onto his temples, loosened his necktie, and spilled a quarter-cup of hot tea across the low table beside him. To anyone peering through the door, the baron had suffered a sudden bronchial spasm brought on by cabin pressurization, knocked over his cup, and slipped into a peaceful stupor.

\"Ingenious,\" Shizuka said. There was a razor-thin smile on her pale mouth. \"You treat an ancient hunger like an untidy spill.\"

\"First-class passengers are always causing untidy spills,\" I replied dryly. \"Most just use wine.\"

Then I glanced upward, and the breath caught in my chest.

Directly above the heavy velvet drapes, the brass intake grille of the ship's pneumatic scrubber was encrusted with thick, iridescent frost. When Shizuka had inhaled Minato's emotional exhalations, her uncanny aura had condensed against the warm metal of the ventilation shaft. Tiny chemical crystals shimmered like powdered sugar along the copper louvers.

\"The intake,\" I muttered.

\"Does it displease you?\" she asked softly.

\"It will displease the chemical litmus sensors inside the pneumatic line. If that vapor gets sucked into the central scrubbers, the mercury needles in the purger watch-post will peg red.\"

I did not wait for her permission. I dragged a mahogany footstool beneath the vent, pulled a clean flannel tea-cloth from my apron, and soaked it with boiling water from the bronze kettle. Stepping onto the stool, I reached up and pressed the steaming cloth against the frozen copper slats.

The heat sizzled on contact. Pungent, sweet vapor puffed against my face, carrying a sharp metallic tang that made my tongue go numb. I scrubbed hard, wiping away every trace of the crystallized frost, trapping the oily grey residue inside the wet flannel. I worked with methodical, frantic precision, leaving the copper polished and bone-dry.

When I stepped down from the stool, Shizuka was standing less than two paces away.

Up close, the cold emanating from her skin was breathtaking. Her dark hair was pinned with needles of black jet, and her skin possessed the smooth, luminous quality of sculpted lard. Yet beneath that terrifying stillness lay an absolute, quiet predator.

\"You are very thorough, Kazuki,\" she said.

My name on her lips sent a sharp shiver down my spine. \"I like staying alive, Countess. And I prefer my lungs unburned by purger gas.\"

She looked from the unconscious baron on the couch to the damp, chemical-stained cloth bunched in my fist. Then her gaze dropped toward my waist, where the outline of Minato's heavy brass cargo passkey bulged slightly against the coarse linen of my apron.

\"You have quick fingers as well as a sharp nose,\" she said softly. \"The baron came here to bargain with me. He claimed he had access to the sealed lower compartments. He thought his little secrets would buy my favor.\"

\"The baron was an idiot,\" I said bluntly. \"Anyone who brings secrets to Suite Nine deserves whatever he loses.\"

A low, eerie sound came from her chest—a sound that might have been a laugh, had she possessed the warmth to laugh.

\"Perhaps,\" she agreed. \"Come back tomorrow at six bells, Kazuki. Bring fresh mint with the infusion. I find the smell of these mortal passengers grows stale rather quickly.\"

\"As you wish, my lady.\"

I turned toward the door, my pulse finally beginning to settle into a steady rhythm. The migraine had vanished. My mind felt sharp, clear, and cold. I had survived Suite Nine. I had a monster's promise of peace, and a restricted cargo key burning a hole in my pocket.

Then the iron ribs of the Kurogane shuddered.

Deep within the bulkheads, a pneumatic valve slammed shut with the force of an artillery shot. Steam hissed furiously through the walls, rattling the brass light sconces.

A heartbeat later, the high, piercing wail of the ship's pressure sirens tore through the passenger deck, signaling a catastrophic failure in the ventilation line.
