The Melted Proxy

The red indicator light above Cleanroom 3's reinforced hatch remained solid, which meant the airlock was drawing six hundred watts of uninterrupted emergency current from a station that had less than forty hours of diesel remaining. Kemo stood four feet from the steel threshold on Habitat Ring 2, his gloved fingers resting against the cold brass housing of his carbon pry bar. To enter without triggering the automated halon dump and sealing the lab permanently behind magnetic deadbolts, he needed more than brute leverage. He needed the analog override sequence that only one person in the facility had memorized.

He turned his back on the sealed hatch and walked thirty paces down the corridor into the partitioned pantry at the back of the mess hall.

Duli sat curled on a metal bench beside an iron radiator, her hands tucked deep inside the sleeves of her oversized survival parka. Her skin looked gray under the halogen strip, but her chin came up the instant Kemo stepped through the hanging canvas drape. Across the table, a cup of lukewarm rehydrated broth sat untouched.

"The biometric sensors in my laboratory do not run on central logic," Duli said before Kemo could speak. Her voice had the dry, brittle snap of someone accustomed to boardrooms and budget hearings. "They are keyed to my retinal mapping and an encrypted pulse monitor. You cannot pry the door open with a crowbar, Kemo. If you force the latch, the pneumatic seals discharge liquid nitrogen into the server racks to protect the foundation's patents. You will destroy whatever data you are looking for."

"I am not looking for data," Kemo said. He set his utility kit on the metal table. The steel tools clicked against the galvanized top. "The proxy signal that bounced the nightly mainland packet at nineteen-fifty came from your diagnostic terminal. Foni is tied to a milling machine in Sub-Level 1. That leaves someone else sitting at your desk."

"No one sits at my desk." Duli pulled her knees closer to her chest. "The cleanroom is an airtight quarantine environment. You have my keycard. Look at it. Even if someone stole a master maintenance credential, the internal chamber requires a sixty-second scrub cycle."

"Every quarantine chamber built under the 1948 mining code has a mechanical bypass for fire suppression maintenance," Kemo said. "A secondary hydraulic valve behind the intake vent. Tell me the bleed pressure."

"I don't know what you're talking about."

Kemo did not raise his voice. He reached past the corner of the table, gripped the cast-iron valve wheel on the radiator pipe, and turned it three full rotations clockwise. The hiss of circulating glycol died instantly inside the pipe. The metal began to tick as the heat collapsed.

"The ambient temperature in this pantry will drop to five degrees below zero in twelve minutes," Kemo said. "Your thermal layers are rated for cabin standby, not deep freeze. You can sit in the frost until your fingers stiffen, or you can give me the valve calibration."

Duli stared at the darkening iron radiator. Her jaw tightened, and she pulled her collar up to her chin. "You are hired security. You have no legal standing to seize proprietary research assets."

"Your contract was terminated the moment your name appeared on the amortized debt ledger," Kemo said evenly. "Right now, you are living on station reserves that belong to the surviving mechanics. Tell me the bleed pressure."

Ten seconds passed in the silent room, measured only by the faint hum of the mess hall generator down the hall. Duli watched her own breath begin to billow in pale gray plumes against the canvas curtain.

"The secondary decontamination loop uses a dual-chamber differential," Duli whispered, her voice dropping into a ragged rasp. "The intake valve is behind the primary HEPA panel in the ceiling alcove. You have to bleed the glycol return down to forty-two pounds per square inch. If the pressure drops below thirty-eight, the differential sensor interprets it as an explosive decompression and drops the magnetic deadbolts. If it stays above forty-six, the outer hatch remains locked."

"And the electrical override?" Kemo asked.

"The bypass harness is behind the diagnostic panel on the left jamb. Three terminals. You must jump the middle ground to the yellow auxiliary lead while holding the hydraulic release." She looked up at him, her dark eyes hard with bitterness. "If your timing is off by three-tenths of a second, the halon canister fires. The gas will displace every cubic inch of oxygen in that vestibule in under five seconds. You'll drop where you stand."

"Then we will keep our timing clean," Kemo said.

He stepped to the radiator valve, cracked it open half a turn to restore a trickle of glycol, and walked out into the mess hall.

Homi was waiting near the central heating manifold, leaning against an insulated drum of hydraulic fluid with a portable multimeter hooked over his shoulder. At the far end of the room, Tano and Sima were securing the welded steel braces around the secondary supply pipes, their breath fogging in the drafty air.

"Did our esteemed researcher offer a voluntary donation of trade secrets?" Homi asked, adjusting the strap of his tool bag.

"Forty-two pounds on the return line," Kemo said, picking up a twin-gauge manifold and two braided high-pressure hoses from the workbench. "Three-terminal jump on the left jamb. Ground to yellow auxiliary."

Homi whistled softly through his teeth. "A forty-two pound window on a forty-year-old pneumatic rig. That gives us about a four-pound margin of error before the system thinks the station wall got punched out by an iceberg and floods the hall with suffocation gas. A truly comforting contingency."

"Grab the insulated jumpers and the brass bleed key," Kemo said. "We have twenty minutes before the next scheduled boiler rotation."

They moved down the north corridor toward the medical wing in silence. The air in the secondary branch was noticeably colder than the mess hall; frost had already begun to form along the rivet lines of the wall plates, glittering like coarse salt under the red emergency lights.

At the threshold of Cleanroom 3, the heavy airlock door stood impassive. The brushed steel surface was cold enough to stick to skin. Above the reinforced observation port, an analog pressure gauge showed the internal chamber sitting at a steady positive pressure of twenty-five pascals.

Kemo knelt beneath the ceiling alcove, unfastened the four knurled screws on the HEPA filter access panel with his fingers, and lowered the steel grate. Inside the dark recess, coated in a fine layer of gray dust and dry grease, sat the secondary decontamination valve block. Two copper glycol lines ran parallel into a brass regulator body fitted with a spring-loaded needle valve.

"Homi. Open the diagnostic panel on the jamb."

Homi knelt beside the door frame, produced a thin flat-head screwdriver from his breast pocket, and levered off the stamped aluminum cover plate. A tangle of color-coded wiring harnesses spilled out into the dim red light.

"Three terminals, just like she said," Homi muttered, clicking on his penlight. "Black ground on the left, red supervisory line in the center, yellow auxiliary on the right. If I bridge ground to yellow while the line is energized, the logic board will look for the pressure drop. Kemo, if that needle valve sticks, we are going to inhale eighty liters of compressed halon."

"Attach your jumpers," Kemo said.

He hooked the braided hose from his dual-gauge manifold onto the brass Schrader valve of the glycol return line. The needle on his gauge snapped to fifty-one pounds per square inch. Nine pounds too high.

Kemo held the brass bleed key in his right hand, positioning the slotted tip over the needle valve's release spindle. With his left hand, he gripped the manual mechanical latch on the airlock hatch.

"Ready on the electrical bridge," Homi said, holding the two insulated copper alligator clips poised above the terminals. "On your three-count."

"Three," Kemo said.

He cracked the brass bleed key a quarter turn. Glycol hissed into the drain reservoir of his manifold, the pale green fluid swirling through the sight glass.

"Two."

The needle dropped smoothly: forty-eight, forty-five, forty-three.

"Now," Kemo said.

The needle touched forty-two. Kemo held the valve steady against the spring tension while Homi snapped the jumper clip across the black and yellow leads.

A sharp electrical click resonated inside the jamb. For a heartbeat, the high-pressure solenoid shuddered, its metallic groan vibrating through the concrete floor. Then, with a heavy pneumatic thud that echoed down the empty corridor, the magnetic deadbolts retracted. The rubber gasket around the outer hatch expanded with a wet hiss.

Kemo pulled the heavy steel handle downward. The door swung outward on greased pivot hinges.

No halon discharged. The air that spilled out of the decontamination vestibule was dry, sterile, and smelled faintly of scorched insulation and ozone.

Homi exhaled a long breath that turned white in the cold air. "I'll admit, my calculations gave us a thirty percent chance of immediate asphyxiation. You have remarkably steady hands for a bodyguard."

"Pack the jumpers," Kemo said, drawing his utility flashlight from his tactical vest. "Stay behind me."

They stepped through the vestibule, crossed the rubberized inner threshold, and entered Cleanroom 3.

The laboratory was larger than the living quarters on the upper ring. Three long stainless-steel workbenches occupied the center of the room, lined with centrifuges, sealed glass desiccators, and racks of cryo-vials labeled in Duli's precise, cramped handwriting. Along the far wall stood the primary research array: an eight-bay mainframe housing flanked by two CRT monitors and an analog tape carousel.

The room was pitch black except for the amber standby lights on the wall panels.

Kemo swept his flashlight beam across the floor. There were no footprints in the light dust near the door, but three paces into the room, the beam caught a smear of dark industrial grease on the corner of the center bench.

"Someone was working here within the last six hours," Kemo said, pointing the light at the stain.

"Look at the main terminal," Homi whispered, stepping around the central table.

Kemo brought his flashlight up to the mainframe console.

The main terminal screen was shattered from within. The glass was bowed outward in a web of hairline fractures, blackened by heavy soot. Inside the lower drive enclosure, where the secondary proxy routing drum should have been mounted, sat a lump of melted alloy and charred copper winding. The pungent stench of burned polyester resin hung thick in the stagnant air.

"A chemical incendiary pencil," Kemo said, inspecting the warped chassis. "Placed directly on the read-head assembly. It burned at over eight hundred degrees for about twenty seconds. The entire storage spool is fused into a single slug of slag."

"They torched the proxy," Homi said, leaning in with his penlight to examine the scorched housing. "The nightly nineteen-fifty transmission was the last bounce they needed. Once the packet went out to the mainland, the handler destroyed the physical bridge so we couldn't recover the transmission logs or the destination seed."

"They didn't just torch it," Kemo said. "They did it while we were moving Duli from Quarters 1."

He reached into the narrow gap between the melted terminal housing and the side of the cooling stack. His gloved fingers brushed against a piece of heavy material tucked behind the intake louver.

Kemo drew it out into the flashlight beam.

It was a square of waxed linen drafting cloth, torn jaggedly along one edge. Sketched across the surface in thick, black grease pencil was a detailed schematic of Habitat Ring 2's secondary ventilation shafts.

The lines were fresh; the grease had not yet hardened in the dry cold of the room. Red wax marks traced a specific pathway leading from the Cleanroom 3 exhaust vent, bypassing the central corridor completely, and terminating directly above the boiler manifold where Tano and Sima were working on the pipes.

At the bottom of the linen sheet, written in block letters with the same heavy grease pencil, were three numbers:

`05:15`

`MANIFOLD 2`

`ZERO FLOW`

Homi stared at the linen sheet, his usual relaxed posture vanishing. "Five-fifteen. That's twenty-five minutes from now."

"They aren't trying to hide in the vents," Kemo said, folding the linen square and sliding it into his breast pocket. "They are clearing the crew away from the heat core."

"Tano and Sima are down there right now," Homi said, his voice dropping into urgent focus. "If someone drops an incendiary into the manifold return, the glycol lines will flash-boil. The pressure will rupture every radiator on the ring."

Kemo turned toward the airlock exit, his boots striking the steel floor in rapid, measured strides. "They don't know we have the map. We don't wait for five-fifteen."

"What do we do?" Homi asked, hurrying to keep pace as they cleared the decontamination threshold.

"We go back to the mess hall," Kemo said, securing the carbon pry bar in his belt loop. "And we take the high ground before they reach the vent."
