Read Chapter 10: The Silent Alarm

The alarm woke Élise from a sleep she hadn’t consciously entered. One moment she was staring at the ceiling of her quarters, tracing the water-stained seam above her bunk; the next, the base-wide klaxon ripped through the corridor speakers with that particular electronic screech that meant air loss. Not fire. Not hull breach. Air loss, the slow kind that kills you before you notice you’re lightheaded.

She was moving before the second cycle. Her boots slapped the deck plating as she ran, pulling her emergency mask from her hip pouch and pressing it against her face. The sealed membrane hissed against her skin. Oxygen bloomed in her lungs.

The corridor lights had switched to emergency amber, pulsing in sync with the klaxon. Other crew members stumbled from their quarters, half-dressed and wild-eyed, fumbling with their own masks. Élise counted them as she passed. Ten. Twelve. Sixteen. She knew the roster by heart. Ninety-one crew aboard Luna Secunda, not counting the two who were scheduled for rotation home in six weeks. Three if you counted Vasseur, who was never here, whose name she now saw stamped on a hundred forged documents in her mind’s eye.

“Where’s the leak?” someone shouted after her.

“Hydroponics,” she called back without slowing. She could feel it in the pitch of the klaxon. A minor discrepancy, Section C-3, oxygen partial pressure dropping two millibars below threshold. Nothing catastrophic. Nothing that should have triggered a full-base panic.

So why was the alarm screaming?

She hit the hatch to Hydroponics Bay and pulled it open. The air inside tasted wrong immediately, that metallic tinge of processed air mixing with something green and organic, the chlorophyll smell of the algae tanks gone sour. A fine mist hung in the air near the far wall, illuminated by the grow lights like frozen rain. The leak was there. Small pinhole in a feeder line, leading to one of the emergency scrubber units. The kind of thing that happened twice a week on any station. Interchangeable. Patchable.

Élise grabbed the repair kit from the wall station and crossed the bay, her mask fogging as she worked. The pinhole was easy to find. She cut the pressure, pulled the line, and applied the patch sealant in three smooth motions. Then she cycled the system and watched the sensor readout on her wrist computer climb back to nominal.

The klaxon cut off three seconds later.

Silence flooded the bay, thick and sudden. The grow lights hummed. The algae tanks bubbled. Élise stood there in the quiet, breathing recycled air through her mask, and felt something cold settle in her chest that had nothing to do with the temperature.

The alarm had sounded base-wide. She’d heard it in the corridors. But the emergency broadcast system used localized zones for minor events. A leak in Hydroponics should have triggered only the adjacent sections and the command deck. Standard protocol, written into the base’s operating manual, which Élise had read cover to cover in her first week on Luna Secunda six years ago.

A full-base alarm meant someone had manually overridden the zoning.

Or the system had been told to treat minor leaks as catastrophes.

She unsealed her mask and let it hang around her neck. The recycled air hit her face, warm and faintly sour. She walked back through the corridors, noting the crew members still clustered in doorways, masks dangling, eyes wide. They were rattled. Of course they were rattled. An alarm like that meant something serious. It meant the base might be failing.

Élise stopped at the junction between Hydroponics and the residential ring. Two maintenance bots sat idle in their charging alcoves, their optical sensors dark. She looked past them, down the east corridor toward the management wing. The lights there were normal white. No emergency amber. The klaxon had blared in the crew quarters, in the mess hall, in Hydroponics and the workshop and the medical bay. But that corridor, the one with Fournier’s office and the administrative suite and the conference room where they’d all been told the base was structurally sound and nothing was wrong, was quiet.

Dark. Silent.

She checked her wrist computer. The alarm log confirmed it. Emergency broadcast, Luna Secunda base, zones A-1 through G-9. All zones. Except one.

Zone H.

The management quarters.

The automated system had been told to exclude them.

Élise stood in the dark junction, the grow lights humming behind her, and felt the cold in her chest spread down into her stomach. She’d fixed the leak in four minutes. That wasn’t the point. The point was that someone had decided the management didn’t need to hear the alarm. The point was that someone had decided the crew would panic, but Fournier wouldn’t.

She turned and walked back to her quarters, her steps deliberate. The door cycled shut behind her and she locked it manually, a habit she’d developed after the Jackson incident, after she’d learned that privacy on a remote station was an illusion maintained by people who didn’t care about your secrets.

Her hidden drive was still in place, taped behind the vent grille above her bunk. She pulled it out, cracked the seal, and plugged it into her personal terminal, the one she’d re-flashed with open-source firmware because the standard OS had too many eyes. The evidence was all there. Vasseur’s forged travel records. The structural survey contradicting itself. The A21 alloy sections mapped across the base like a constellation of betrayal. Callum O’Brien’s cargo manifests.

She opened the alarm log she’d just queried and added it to the file. Quiet zone for management. Silent alarms. They’d wanted to test the crew’s response. Or they’d wanted to observe it.

She knew Fournier. She’d worked with him for eighteen months and she could picture exactly how this went. Fournier in his office, coffee in his mug with the chipped rim, watching the crew scramble on a screen while the manager’s quarters stayed placid and quiet. He wouldn’t have known about the leak. He wouldn’t have cared. Someone else had configured the exclusion, or Fournier had ordered it, or—

The pattern clicked into place with a soft, awful certainty.

The base was being conditioned. The crew was being shown that alarms were common, that leaks happened, that everything was under control. Meanwhile, the structural integrity reports were being doctored, the ship was incoming, and no one in management was ever hearing the alarms.

They weren’t preparing to evacuate the crew. They were preparing the crew to accept an evacuation when it came. To be docile. Compliant. The alarm system was a rehearsal.

Élise pulled the drive, sealed it, and tucked it back behind the vent grille. Then she sat on the edge of her bunk and stared at the opposite wall, where a faint crack ran from the ceiling to the floor, invisible to anyone who didn’t know where to look.

She knew where to look now.

The doc’s office was three corridors away. Dr. Hélène Magnusson had been on Luna Secunda for two years, longer than most of the medical staff, longer than Fournier. She kept the medical records. She kept the secrets. She might know something about sedatives scheduled to quiet restless workers in the weeks before an evacuation. She might know what the crew had been given that they hadn’t consented to.

Élise didn’t move.

The alarm had been silent in management quarters. The crew had panicked at a minor leak. The base was failing around them—structurally, systematically, morally—and the people who were supposed to protect them had cut themselves off from the sound of their own destruction.

She looked at the clock. 02:47. The night shift was running. Dr. Hélène would be in her office until eight.

Élise stood up. She didn’t know what she was going to say. But she knew one thing with terrible clarity: she couldn’t fix the leak in the system the way she’d fixed the pinhole line. There was no patch for this.

She opened her door and walked toward the medical bay, the emergency amber still faint in her peripheral vision, fading from the corridor lights as the base returned to normal.

It wouldn’t be normal again.
