1. The Last Supply Drop

The last supply flight of the season was a speck of black against a cataract sky, its engine drone swallowed by the wind before the fuselage fully materialized out of the polar twilight. Viktor Haas stood at the edge of the landing zone, one gloved hand raised to shield his goggles, the other clutching the radio handset. He had been logistics officer at Caldera Station for fourteen months, and he never stopped marveling at how the Antarctic could make a C-130 look like a child’s toy tossed into a freezer.

“Caldera Station, this is Isbjørn Four. Descending to five hundred meters. Wind shear is moderate. Confirm landing flags are lit.” The pilot’s voice crackled through the handset in clipped, accented English—Norrøna Air Transport, the only carrier still willing to make the late-February run after the Vostok incident two years prior.

“Flags are lit, Isbjørn Four,” Viktor replied. “You’re clear to drop on the orange markers. Be advised, the surface is refreezing after yesterday’s warm spell. We’ve got a glaze layer that’ll make the crates slide like pucks.”

“Copy that. Commencing drop in sixty seconds.”

Viktor clipped the handset to his belt and waved toward the station, a cluster of corrugated-metal modules half-buried in drift, connected by insulated tunnels that leaked steam into the frozen air. Two figures emerged from the main habitat module and trudged toward him: Mira Larsen, the station’s glaciologist, and Anya Petrov, the junior engineer whose contract had been extended after her predecessor suffered a mental breakdown during the polar night. Mira walked with the measured stride of someone who had spent two decades on ice sheets; Anya walked like someone who was still surprised by the sound of her own boots on packed snow.

“Last care package before winter,” Mira said, pulling her balaclava down just enough to speak. “I hope he remembered the paprika. We’re down to salt and despair in the kitchen.”

Anya said nothing. She kept her eyes fixed on the descending aircraft, her breath forming shallow clouds that the wind tore away instantly. She had been quiet for weeks—quieter than usual, even for someone with an introvert’s disposition—and Viktor had noticed. He noticed everything about the station’s supplies, and he noticed when people’s behavior shifted by even a degree. In a crew of seven, a degree became a continent over time.

The C-130 dropped its rear ramp and disgorged a pallet of cargo suspended beneath a parachute. The crates thumped onto the ice fifty meters from the flags, cracking the glaze layer and sending splinters of refrozen meltwater into the air. Viktor was already moving with the snow tractor before the parachute collapsed.

By the time the plane had banked north and vanished into the cloud ceiling, the three of them had wrestled the crates inside the garage module. Viktor began cataloguing supplies with the meticulousness of a man who knew that a single misplaced calorie could become a life-or-death equation in late August. Mira tore open a crate of dehydrated vegetables and let out a satisfied grunt when she found a vacuum-sealed bag of smoked paprika. Anya sat on an overturned fuel drum, rubbing her wrists—a nervous tic Viktor had catalogued in his mental ledger months ago.

“Any news from the outside?” Mira asked.

“Norrøna Tower said the satellite relay station at McMurdo is down for maintenance,” Viktor said, scanning a cargo manifest. “Should be back up in three days. They’ll resend the data dump then.”

“Three days without email from my ex-husband. How will I survive.” Mira’s tone was dry as a nunatak.

Anya looked up. “Three days?”

“Minimum,” Viktor said. “Nothing to worry about. We’ve got the shortwave if there’s an emergency.”

Anya nodded slowly, but her hands kept rubbing her wrists.

The storm arrived faster than any of the forecasts had predicted. By 2100 hours, the wind was screaming across the ice sheet at eighty kilometers per hour, and the station’s outer modules were shaking with a low-frequency vibration that made conversation difficult. Station Chief Arne Falk—a Norwegian geophysicist with thirty years of polar experience and a face weathered into a permanent expression of controlled disappointment—ordered all external activity suspended. The satellite link, already compromised, went completely dead at 2230 hours. The shortwave receiver picked up nothing but a howling static that seemed to mimic the wind outside.

The seven inhabitants of Caldera Station gathered in the common module for the mandatory safety briefing. Mira sat in her usual corner, nursing a mug of black tea. Anya was curled into the far end of the sofa, knees drawn up, eyes fixed on the floor. Beside her, Dr. Samir Khalil, the station’s physician, was pretending to read a worn paperback. Erik Dahl, the meteorologist, sat perfectly still in a metal folding chair, his hands resting palms-down on his thighs, his pale blue eyes tracking Falk’s every movement with the detached curiosity of a spectator at a chess match. The seventh crew member, communications officer Lena Jansson, was still in the radio room, trying to find a signal that did not exist.

“Until the satellite relay is restored, we are on our own,” Falk announced, his voice carrying the weight of institutional authority. “All non-essential power consumption is suspended. Water rations are reduced by fifteen percent. No one leaves the habitat module without a buddy and a fully charged emergency beacon. Is that understood?”

A murmur of assent rippled through the room.

“And Viktor,” Falk added, turning to the logistics officer, “I want an inventory of all emergency supplies by 0800 tomorrow. If this storm lasts longer than the forecast, we’ll need to adjust.”

Viktor nodded. “I’ll do a walk-through of the storage tunnels tonight. The wind should ease around midnight.”

It was the last time anyone saw Viktor Haas alive.

Mira woke at 0400 to the sound of silence. The wind had died, replaced by a stillness so profound that her own heartbeat felt intrusive. She pulled on her insulated layers and made her way to the kitchen module, where she found Samir already brewing coffee.

“Couldn’t sleep either?” she asked.

“The quiet wakes me up more than the storm,” Samir said, handing her a cup. “Something about the transition. The body knows when danger has passed.”

They sat in companionable silence until Lena appeared in the doorway, her face pale beneath the station’s fluorescent lights.

“Viktor didn’t come back,” she said. “His bunk hasn’t been slept in. His radio is off.”

A search began within fifteen minutes. Falk organized the crew into pairs: Mira and Anya to the storage tunnels, Samir and Erik to the outer modules, Lena and Falk to the immediate perimeter. The sun would not rise above the horizon for another two months, but the twilight was just bright enough to navigate by, a perpetual blue dusk that turned the landscape into a monochrome of shadows.

Mira found him.

The crevasse was not marked on any of the station’s hazard maps. It had opened during the previous summer’s melt season, a narrow fissure hidden beneath a crust of wind-packed snow, less than two hundred meters from the main storage tunnel entrance. Viktor had known this route like a muscle memory—he had walked it dozens of times during the winter—but the storm had erased the subtle landmarks, and the snow bridge over the crevasse had collapsed under his weight.

His body lay twelve meters down, wedged between two walls of ice that glowed faintly blue in the beam of Mira’s headlamp. His safety harness was still attached to his chest, but the nylon webbing of the tether strap was frayed, its severed ends waving gently in the draft that rose from the depths.

“Don’t come closer,” Mira called over her shoulder to Anya, her voice calm but sharp. “The edge is unstable.”

Anya had already stopped walking. She stood frozen ten meters back, her headlamp beam shaking slightly as she stared toward the crevasse. “Is he—”

“He’s dead.” Mira said it flatly, because there was no point in softening the words. The angle of Viktor’s neck made the fact unambiguous even from this distance. “Go back to the station. Get Falk. Get the rope kit from the garage. Don’t run, the surface is still slick.”

Anya turned and walked back toward the lights of Caldera Station. Mira watched her go, then knelt at the edge of the crevasse and directed her headlamp at the severed strap ends.

The fraying was too even. Too clean. Under magnification, the outer fibers showed signs of being sliced partway through, the cut camouflaged by a later tearing that had been deliberately roughened to mimic natural wear. Someone had tampered with Viktor’s harness.

Mira took a series of photographs with her headlamp camera, then stood up and scanned the snow around the crevasse. There were footprints—Viktor’s, unmistakably, given the distinctive tread pattern of his boots—but also a second set, partially erased by drifting snow, approaching the crevasse edge from a different angle and retreating back toward the station.

She said nothing about any of this during the recovery operation. Falk and Samir hauled Viktor’s body out of the crevasse with grim efficiency, and Lena radioed a formal report into the dead air, her voice steady despite the tremor in her hands. Erik Dahl stood apart from the group, watching the extraction with that same quiet, analytical expression he had worn during the briefing. If he felt grief or shock, he kept it behind the wall of his face.

They laid Viktor’s body in the medical module, and Samir conducted a preliminary examination. The cause of death was blunt-force trauma to the skull, consistent with a fall from height. The frayed harness was noted and photographed. Samir’s medical report, filed on paper because the electronic systems were still down, described the equipment failure as “suspicious in origin.”

Falk convened the crew in the common module at 0700. His face was drawn, and his voice carried an edge that no one had heard before.

“Viktor Haas is dead,” he said. “The circumstances of his death will be investigated fully once communications are restored. Until that time, we are both a station and a crime scene. I am instituting isolation protocols. No one is to destroy or dispose of any personal effects, equipment, or records. All crew members will submit to an interview with me within the next twenty-four hours.”

He paused, and his gaze moved slowly across the room, settling for a moment on Anya Petrov, who was sitting rigidly in the corner, her hands clasped so tightly in her lap that her knuckles were white.

“If anyone has information about Viktor’s movements last night, or about the condition of his equipment, they will come forward now.”

Silence.

“Very well,” Falk said. “Interviews will begin at 0900.”

The crew dispersed, and Mira found herself walking beside Erik Dahl in the narrow tunnel connecting the common module to the sleeping quarters. He moved quietly, his footsteps barely audible even on the metal grating.

“You were out there before we found the body,” Mira said, not looking at him. “I saw your boot prints when I went back to photograph the scene.”

Erik stopped walking. The pause stretched for three heartbeats before he spoke. “I was checking the wind-speed gauge at the perimeter. It’s my job.”

“The gauge is on the north side. The crevasse is to the south.”

“I took a longer route. The aurora was visible.”

It was a plausible answer. The aurora had been unusually active during the storm’s lull, and Erik was the station’s meteorologist. But the way he said it—too calm, too prepared—settled in Mira’s stomach like a stone.

That night, she lay in her bunk and stared at the ceiling, replaying the day’s events in her mind. The cut in the harness. The second set of footprints. Falk’s gaze landing on Anya as if an accusation had already formed. And Erik Dahl, who had been the only person awake and unaccounted for in the hours after Viktor disappeared.

She thought of something Viktor had said to her three days earlier, during a routine inventory of the kitchen stores. He had been holding a clipboard, frowning at something on the page, and then he had looked up with an expression she couldn’t quite read.

“Mira, do you ever get the feeling that someone here isn’t who they say they are?”

She had laughed it off at the time. Now the question returned to her like an echo from the ice, colder and sharper than before.

In the bunk next to hers, Anya Petrov shifted in her sleep and made a small, frightened sound—a fragment of a nightmare that could not be outrun even in dreams.

Mira closed her eyes and listened to the station breathe: the hum of the generator, the creak of metal contracting in the cold, and beneath it all, the silence of a mystery that had already begun to coil itself around them, tighter than any storm.
