The Tide Wall
Read Chapter 15: The Broadcast Sneak
The cargo drone shuddered as Anya banked it hard between two skeletal cranes, the antenna tower looming ahead like a black needle stitched into the bruised sky. Finn pressed a hand to his side, feeling the wet warmth of his reopened wound seep through his fingers. He said nothing. Anya had enough to carry.
“There,” she said, pointing through the canopy. “The service apron at the base. The floodgate control conduit runs under it. I’ll set us down soft, but we’ll have maybe ninety seconds before their perimeter sweep loops back.”
Finn watched the ground come up. The tower’s base was a reinforced concrete ring, ringed with floodlights that cut white cones through the drizzle. A maintenance hatch sat recessed in the apron, barely visible beneath a tangle of corroded pipework. He’d seen hatches like that before, on ships, on rigs—places people forgot. That was the point.
The drone settled with a jolt. Anya killed the rotors and they dropped out, moving low and fast. Finn’s leg screamed with every step. He gritted his teeth and kept going.
Anya reached the hatch first, pulling a pry bar from her jacket. She worked the edge, grunting. The seal gave with a wet gasp of trapped air. She looked back at him, and Finn saw the question in her eyes: *Can you make it?*
He nodded. He didn’t have a choice.
They dropped into the conduit. It was a narrow, damp crawlspace lined with bundled cables and fat pipes, the air heavy with the smell of stagnant water and machine oil. Finn consulted the partial schematic Anya had pulled from the drone’s memory. The secondary feed ran along the eastern wall, spliced into the floodgate control backbone, then routed up into the tower’s lower transmitter bank. If they reached the junction box, he could piggyback the broadcast signal onto the maintenance channel—too slow for a full upload, but enough to bleed the data out in fragments. If it worked, the signal would bounce through the city’s relay nodes, untraceable until it was already in the open.
“This way,” he said, and started crawling.
They moved for what felt like an hour but was probably twelve minutes. Finn’s hands shook from blood loss and adrenaline. Twice he had to stop, breathe, wait for the black at the edges of his vision to recede. Anya didn’t push him. She just scanned the shadows ahead, listening.
The junction box was bolted to the wall beside a ladder that led up into the tower’s lower service floor. Finn pulled himself upright, leaning against the cold metal, and popped the box’s cover. Inside, a tangle of fiber and copper waited. He found the transmitter feed, then located the maintenance channel’s access port.
“I need to wire the chip into this,” he said, pulling Chen’s data chip from his inner pocket. It was still warm from his body heat. “But the encryption handshake on the main array will reject it. I have to spoof the maintenance protocol first.”
Anya watched him work. “How long?”
“Ninety seconds. Maybe two minutes if the handshake’s finicky.”
“That’s a long time up here.”
“Then keep watch.”
He bent over the box, fingers moving with the muscle memory of a man who had spent years coaxing life out of dying systems. The chip slid into a reader port he jury-rigged from a scavenged sensor lead. A tiny LED blinked amber, then green. Data began to flow—slowly, painstakingly, through the narrow maintenance channel.
“Upload started,” he said. “Eleven percent.”
Anya keyed her earpiece. “Incoming feed from the drone’s sensors… they’re scanning the apron. We’re clear for now.”
Fourteen percent. Nineteen.
Finn felt the vibration through the floor before he heard it. Boots, running on the service floor above. He froze. Anya turned, hand going to the compact pistol at her hip.
“They’re on the catwalk,” she whispered. “Three of them. They’re checking the junction.”
Twenty-six percent. Too slow.
Finn looked at the box, at the tiny chip, at the ladder leading up into the tower’s guts. He had two choices. He could keep bleeding data through this line—risking discovery, risking the entire upload being purged the moment security found the junction. Or he could sever the feed, copy what had already been sent to a backup node he’d have to locate blind, and hope the partial message was enough to ignite the response he needed.
But there was a third option, one he hadn’t told Anya about. The schematic showed a secondary server node, buried in the floodgate control bunker that ringed the tower’s substructure. It was designed as a failsafe—a place where critical calibration data could be mirrored if the main array went down. If he routed the backup there, it would sit dark and dormant, invisible to the tower’s security sweep. No one would know it existed until someone went looking.
But sending the backup meant diverting the upload’s power. The public feed would cut out at maybe forty percent. Incomplete. Fragmented. Enough to raise questions, but not enough to provide proof. The backup would be complete, but secret. Useless unless someone knew where to look.
“Finn,” Anya hissed. “They’re coming down the ladder.”
Forty-one percent.
He made the call.
His hand shot out, ripping the chip from the reader. Anya’s eyes went wide. He ignored her, scrambling to the floor panel beneath the junction box. His fingers found the seam, pried it open. A dark cavity yawned below, filled with the hum of machinery. The failsafe node was down there—he could feel it, a pulse in the dark.
“What are you doing?” Anya whispered.
“They’ll purge the upload the second they see it,” he said, voice tight. “The partial won’t survive. But if I get the full file into the failsafe, it’ll be untraceable. We lose the public broadcast, but we keep the evidence alive.”
“Alive for who? No one will ever see it!”
“Then we send someone to see it.” He didn’t look up. He was already feeding the cable down, threading the chip into the recessed node. A green light blinked once, twice, then steadied.
“Backup mirrored,” he breathed. “Eighty-nine percent of the file. The rest was lost.”
Above them, boots clanged on the ladder.
Anya grabbed his arm. “Go. Now.”
They scrambled into a narrow access tunnel that ran alongside the floodgate control piping, pulling the panel shut behind them. A heartbeat later, they heard the junction box’s cover slam open, followed by a voice: “Signal anomaly. Trace it. Now.”
Finn pressed his back against the cold metal, gasping. Anya crouched beside him, breathing hard. The tunnel stretched away into darkness.
“You just killed the public broadcast,” she said, not accusing, just stating the fact.
“I know.”
“And you hid the backup in a node no one knows exists.”
“I know.”
“How do we get it out?”
Finn closed his eyes. His leg burned. The wound in his side had soaked through his jacket, and he could feel the warm trickle of blood pooling in his boot. He thought of Tess, lying in Mistress Wu’s safehouse, weak and waiting. He thought of Danny, and the key, and the doors that shouldn’t exist.
“We don’t,” he said finally. “Not from here. Not tonight.”
Anya stared at him. “Then what was the point?”
Finn opened his eyes. The tunnel stretched ahead, and somewhere beyond it, he knew, was the floodgate control bunker. And beyond that—a way out. A way back to the low zone. A way back to Tess.
“The point,” he said, “is that they’ll think the evidence died with the upload. They’ll stop hunting it. And that gives us exactly one chance to get it out before they realize it’s still alive.”
He pushed off the wall, swayed, caught himself.
“We need to move. I’m bleeding out.”
Anya looked at him. “And if we don’t make it?”
“Then the backup stays dark. The plan goes through. And everyone in the low zone drowns without ever knowing why.”
He started down the tunnel. Behind him, he heard the guards’ voices growing fainter, muffled by steel and concrete. The city hummed above them, oblivious.
But Finn knew—somewhere in that dark, mirrored node, Chen’s evidence was waiting. And the clock on the initiation date was still ticking.
