Read Chapter 4: The Beacon That Cannot Speak

The antenna mast was a twenty-meter skeleton of carbon lattice and ceramic shrouds, and Élise hated it. Not because of the height, not because of the wind that snapped at her suit whenever she climbed it, but because it was a lie. The storm two weeks ago had supposedly twisted the primary feed line. That was the official report. The official report was now worth less than the dust on her visor.

She locked her mag-boots onto the final service platform and leaned into the crosswind. Below her, Luna Secunda sprawled like a grey scar across the pale regolith—habitat rings, the processing stack, the dark wound of the cargo bay where she’d seen the clean cut in the conveyor.

Beautiful. Broken. Hers.

“You’re wasting time up there, Chief.” Voss’s voice crackled in her helmet. He was on the ground, holding the replacement line spool, his boredom loud even through the tinny speaker.

“Patience is a virtue, Voss. You wouldn’t know it.”

She unclipped the access panel on the beacon housing. The emergency beacon. The one piece of hardware on this whole damn base that was supposed to scream for help if everything else failed. She swung the panel open and froze.

The transmitter core was intact. Pristine. Not so much as a scorch mark. But the main antenna feed—the thick, armored cable that carried the distress signal through the mast and out into the void—was severed. Not snapped by stress fracture. Not degraded by radiation. Cut. A clean, deliberate slice through the copper core, the insulation peeled back like a banana rind and then tucked neatly out of the way, as if someone wanted it to look like an accident but couldn’t be bothered to finish the job.

Élise ran her gloved finger along the cut edge. Polished. A cutting tool had done this. A hand tool. Someone had stood on this platform, probably in the last week, and neutered the base’s only reliable link to Earth.

“Voss,” she said, her voice flat. “I’m going to need a new feed core. This one’s bad. Whole length.”

“Rookie mistake, Chief. That was stamped as pre-scanned.”

“Do I look like I care about the stamp? Get a new one.” She didn’t let irritation leak into her voice, but Voss had known her for twelve years. He went quiet. Then: “On it.”

She listened to his mag-boots thump away down the service ladder, then she leaned closer to the housing. The cut was the story. But there was another story underneath. Something had been jammed behind the transmitter’s main logic board—a small, dark wafer, thinner than a fingernail, tucked into the gap between the board and the housing wall. Not part of the original assembly. Not part of any assembly she’d ever seen.

She pried it out with the tip of her multi-tool. It was a data chip, but non-standard. No label, no port cover, just a raw contact strip on one edge, worn from repeated insertion into some other device and then stripped bare for this one.

She held it up to the harsh sun-glare. Nothing. No markings. No serial. She turned it over. There, etched into the ceramic substrate in micro-lettering so faint she had to squint through her helmet’s mag-view: a nine-character sequence. Numbers and letters that meant nothing to her, but the format was familiar.

It was the same format as the encrypted transmission header she’d decoded from the eastern ridge two days ago.

The same format as the access logs that had her name on them at a time she’d been asleep.

Her heart hammered against her ribs. She pulled the chip into her suit’s sampling pouch, sealed it, and made a note to run a full spectral analysis later. But she already knew what it was. This wasn’t sabotage for destruction. This was a message. A message that couldn’t be sent through the comms array, through the relay satellites, through any channel that Fournier or whoever was pulling his strings could monitor. So someone had cut the beacon’s feed, knowing it would be inspected, knowing a repair chief would open this panel, and knowing that repair chief would be her.

Someone had left her a dead letter drop in the one place no one ever looked when things were working: the thing that was supposed to work forever.

She didn’t tell Voss. She didn’t tell Sébastien when she climbed down and walked past him with the new feed core in her grip. She replaced the line herself, running the tests, watching the link lights cycle from amber to green, noting the time-stamped confirmation that the emergency beacon was now fully operational. That would be in the logs. That would clear her.

The chip stayed in her sampling pouch.

Later, in her quarters, she locked the door and pulled out her personal tablet—the one device on this base that had never been touched by the corporate network because she’d built it herself from spare parts and paranoia. She slotted the chip into an adapter she’d made for exactly this kind of contingency, and the screen flickered.

One file. No header. No metadata. Just a single code sequence, scrolling across the dark screen in slow, deliberate lines.

She didn’t recognize the pattern. It wasn’t navigation data, wasn’t a comms handshake, wasn’t an encryption key she’d ever seen. But she recognized the *shape* of it. The variable-length pulse intervals, the pseudo-random gaps that weren’t random at all.

It was a command sequence for an autonomous docking system. The kind used by uncrewed cargo freighters. But not the standard lunar pattern. This was the deep-space variant, used for remote outposts and mining platforms in the belt.

Luna Secunda didn’t have a deep-space docking system. It had nothing that could receive that command.

She stared at the screen, her breath slow and even. Then she opened a second window on her tablet—the manifest she’d photographed in the cargo area earlier. The one that didn’t match what was physically stacked in the bay. She cross-referenced the flagged item numbers against the command sequence’s pulse intervals, aligning them side by side.

Her skin went cold.

The command sequence matched the cargo schedule. It was timed to trigger a docking cycle in approximately seventy-two hours. The cargo manifest claimed there was nothing scheduled to dock at Luna Secunda for another month.

Élise sat back in her chair. The base’s emergency beacon was disabled so no distress call could interfere with an incoming vessel. The cargo bay had been cleared of personnel during the staged drill—so no one would see the approach. The rotation board had been altered—so the crew that knew the real-day inventory would be gone.

Someone was sending a ship here. A deep-space ship. And they didn’t want anyone to tell Earth about it until it was too late.

She saved the chip’s contents to three separate encrypted partitions on her tablet, then wiped the chip itself and slid it back into its pouch. She would not tell Fournier. She would not tell Sébastien. Not yet. She had to know what was coming before she could decide who to trust.

Seventy-two hours. If she was right, she had three days to find out what was on that ship before it arrived.

She turned off the tablet, stared at the ceiling for a long moment, and allowed herself one small, bitter smile.

Whoever had left that chip knew she’d find it. Which meant they knew she wasn’t going to just stand by and let it happen.

The beacon couldn’t speak. But she could.
