The Tide Wall

Read Chapter 4: The Broker's Price

The Narrowing was a drowned artery of the old city, a channel where the buildings leaned so close overhead that the grey sky was a thread of light. Finn poled his skiff past a half-submerged pharmacy sign, the green cross still glowing faintly from a buried emergency battery. The water here was still as black glass, except where his pole dipped, sending ripples through the reflected corpse of a kebab shop.

Ezra’s place was a former bank vault, accessible only through a submerged loading dock. Finn tied off to a rusted rail, pulled his hood up, and knocked three times on a steel door covered in decades of barnacle growth. A small panel slid open, revealing a single grey eye.

“Finn Delaney. You’re either very brave or very stupid to be out right now,” a tinny voice crackled.

“I’m paying, Ezra. That’s all you need to know.”

The door unsealed with a hydraulic sigh, and Finn squeezed through the gap. Inside, the vault had been converted into a warren of dry platforms, stacked with salvaged equipment—reclaimed circuit boards, sealed watertight crates, old ammunition boxes stamped with the London Enforcer crest. The air smelled of ozone and dried seaweed.

Ezra was small, almost birdlike, perched on a stool behind a counter made from a bank teller’s station. His hands moved constantly, sorting through a pile of microchips, his fingers precise despite the tremor. A dozen flickering monitors lined the wall behind him, showing feeds from across the low zone.

“Sit,” Ezra said, gesturing to a crate. “And whatever you’ve got on you, you can put it on the table, but keep your hands where I can see them. I heard about the commotion near the tube station. Enforcers turned the water to foam looking for something.”

Finn placed the beacon on the counter, a black cylinder the size of his forearm, its surface scarred from where he’d pried the casing open. The small blue LED blipped steadily, still transmitting whatever signal Anya hadn’t fully stripped.

Ezra’s hands stopped moving. He leaned forward, rotating the beacon slowly with the tip of a screwdriver. “High-zone maintenance,” he murmured. “They don’t lose these. They don’t leave these. Where did you find it?”

“Doesn’t matter. I need you to tell me what it does. The encryption was cracked, but the functionality is partial. I know it’s part of flood gate control, but the specifics are buried.”

Ezra reached under the counter and produced a pair of thin magnifying goggles, sliding them over his eyes. He examined the beacon’s interior port for a full minute, his breath shallow, before setting it down.

“This isn’t just flood gate control,” he said slowly. “This is a calibration beacon. See the frequency pattern here?” He pointed to a micro-etched line of circuitry. “It syncs with the main control array. It tells the gates not when to open, but how far, and how fast. It’s a precision tool.”

Finn’s gut tightened. “A drain sequence targeting zones seven through twelve. The beacons confirm the path of the surge.”

Ezra nodded. “Whoever placed this one wanted a specific outcome. Not a flood—a drain. A controlled evacuation of water from certain zones, directing it into others. You’re in sector nine, aren’t you?”

“Ten,” Finn said flatly.

“Close enough. When the gates cycle, your sector becomes a pressure vessel. The water doesn’t recede—it gets pushed through you, to the financial core, to keep it dry.” Ezra’s eyes met Finn’s. “And that means you’re in the way.”

Finn took a breath, steadying himself. “I know. That’s why I need more. There’s a control station—a physical one, where they can override the sequence. I have charts, old navigation maps, but they’re incomplete. They show passages through the wall, but not where they lead on the high-zone side.”

Ezra was quiet for a long time. His fingers drummed on the counter. “I can get you what you need. A schematic of the drainage command network. The location of the main override station. But this is not cheap information, Finn. This is the kind of thing that gets people dropped into the deep channels.”

“I don’t have much currency.”

“I don’t deal in currency,” Ezra said, his voice dropping. He pushed the beacon back across the counter. “I deal in services. And right now, I have a client in the high zone who needs a package delivered. A boatman with your knowledge of the waterways—and your new acquaintance with maintenance infrastructure—is exactly what they need.”

Finn’s jaw tightened. “Smuggling. Into the high zone. Where every bridge has a scanner and every lock has an armed guard.”

“You have a chart showing hidden passages through the wall,” Ezra said mildly. “You already know how to get in. I’m only asking you to bring something back out.”

“What’s in the box?”

“I don’t ask,” Ezra said. “That’s how I’ve stayed alive this long. And that’s how you’ll stay alive too. You take the package, you deliver it, you come back, and I’ll have the schematic waiting for you. The full network—every relay, every failsafe, every way to unpick the perimeter walls from the inside.”

Finn looked at the beacon, its light still pulsing. Four days. Four days until the gates cycled and his district turned to a funnel. He didn’t have time to find another broker, and Ezra was the only one with access to genuine high-zone schematics.

“What’s the drop point?” Finn asked, hating the sound of his own voice.

Ezra smiled, a thin, knowing thing. “You’ll get the coordinates when you accept. The package is in a lockbox three canals east of here, under the old bridge market. Pick it up tonight, deliver it before sunrise, and we’ll call it square.”

“And if the enforcers find me with a mystery box in a high-zone corridor?”

“Then you have bigger problems than a drain sequence.” Ezra pointed at the beacon. “That device you’re holding? It’s not just a calibration unit. It has a dead man’s switch. When the main array activates, it pings every beacon within range. If this one doesn’t respond, the array knows. It recalibrates automatically, adjusts the drain profile to compensate. Whatever plan you’re forming to disrupt the sequence? You’re holding the only copy of the key.”

Finn grabbed the beacon and turned to leave. At the door, he paused.

“One more thing,” Ezra added, his voice softer now. “I saw enforcer activity near your skiff’s original mooring this morning. They found the lithium crate you left behind. They dragged the water for a mile. Whoever you are to them, Finn—you’ve officially become their priority.”

Finn stepped out into the cold, damp air, sealing the vault door behind him. His heart hammered. The lithium crate—the one he’d forgotten, the one Anya had warned him about. The enforcers had it now. Which meant they had a trail to his boat, his home, his sister.

He looked up at the sliver of sky above the Narrowing, then east, toward the bridge market where a package waited for him. Somewhere out there, his father’s old map was tucked into his jacket, but right now it felt less like an inheritance and more like a death sentence.

Four days. One box. A dead man’s switch in his hands.

Finn put his pole in the water and pushed off, the beacon’s blue light pulsing through his jacket like a heartbeat he couldn’t stop.
