The lift doors slid open onto the ground floor of One Canada Square, and Jake, Emma, and Mercer stumbled out into the lobby. The air tasted of metal and smoke. Sirens wailed in the distance — police, fire, MI5 rapid response — all converging on the tower they had just escaped.

Emma pressed her hand harder against Mercer’s wound. “Stay with me. You’re not dying today.”

Mercer managed a weak smile. “I’ll… try not to.”

Jake scanned the lobby — empty, abandoned, lights flickering from the power surge caused by the fire suppression system. The building felt hollow, like the aftermath of an earthquake.

“Move,” Jake said. “We need to get out before Harris locks the place down.”

They pushed through the revolving doors and out into the plaza. Rain hammered the pavement, turning the neon reflections into streaks of colour. The wind whipped between the skyscrapers, carrying the distant thump of helicopter rotors.

Emma looked up. “MI5’s here.”

Jake shook his head. “Not for us. For Harris.”

Mercer coughed. “He’ll spin it. He’ll say we attacked him. He’ll say we’re compromised.”

Jake clenched his jaw. “Not if we get ahead of him.”

Emma frowned. “How? He has the drive. He has the servers. He has the Inner Line.”

Jake turned to Mercer. “But he doesn’t have you.”

Mercer blinked. “Me?”

“You’re the only one who knows the patterns,” Jake said. “The anomalies. The access logs. You can rebuild the evidence.”

Emma nodded. “We expose him. Publicly. Internally. Whatever it takes.”

Mercer hesitated. “If we do this… there’s no going back.”

Jake looked out across the plaza — the flashing lights, the chaos, the storm rolling in over the Thames.

“There was no going back the moment Collins died.”

Emma swallowed hard. “We owe her this.”

Mercer nodded slowly. “Then we need a place to work. Somewhere Harris can’t reach.”

Jake smirked. “I know just the place.”

Emma raised an eyebrow. “Please don’t say the abandoned bakery.”

Jake shook his head. “Better.”

Thames Barrier Control Station — Two Hours Later

The storm raged over the river as Jake, Emma, and Mercer slipped into the old control station — a decommissioned operations room overlooking the massive steel gates of the Thames Barrier. The building was dark, silent, forgotten.

Perfect.

Mercer sat at a dusty console, hacking into MI5’s archived systems using a portable rig he’d hidden years ago. Emma stood guard at the window, watching the river churn. Jake paced behind Mercer, adrenaline still burning through him.

Mercer typed furiously. “I can reconstruct the asset list. Cross‑reference the timestamps. Track the access logs. It’ll take time, but—”

Jake interrupted. “Do it.”

Emma turned from the window. “Jake… what if Harris comes for us?”

Jake didn’t look up. “He will.”

Mercer swallowed. “Then why stay here?”

Jake finally stopped pacing. His voice was calm. Too calm.

“Because we’re not running anymore.”

Emma stepped closer. “Jake…”

He met her eyes.

“We take the fight to him.”

Mercer looked between them. “You’re talking about war.”

Jake nodded. “Harris declared it.”

Emma exhaled. “Then we finish it.”

Mercer returned to the console, fingers flying. “If I can pull the data… if I can prove the Inner Line exists… we can bring them all down.”

Jake placed a hand on Mercer’s shoulder. “Then start.”

Mercer nodded.

The room filled with the soft hum of old servers waking up, the glow of screens flickering to life, the storm pounding against the windows like a warning.

Emma stepped beside Jake. “What happens when we expose Harris?”

Jake looked out at the river — dark, violent, unstoppable.

“Then Operation Captura ends.”

He turned back to her.

“And Operation Retribution begins.”

Emma’s eyes hardened. “I’m with you.”

Mercer raised his head. “So am I.”

Jake nodded once.

A pact.

A beginning.

A war.

Outside, lightning split the sky over London.

Inside, the first files began to decrypt.

And deep in the city, in a hidden room beneath MI5 headquarters…

Harris watched the same storm and smiled.

Because he knew:

This wasn’t the end.

It was the opening move.
