Read Chapter 10: The Debt Collector

The warehouse in Camden smelled of damp concrete and stale diesel. Felix stood in a pool of yellow security light, his silhouette thin against the corrugated steel walls. He didn't move when Alex pushed through the rusted side door. He just watched, arms crossed, a cigarette burning between two fingers.

"You're late," Felix said.

"Your friends tried to kill me on the District line."

"Not my friends." Felix took a long drag, exhaling smoke through his nose like a dragon settling. "But you look like shit, so I'll assume you're telling the truth."

Alex stepped closer. His ribs ached where the Stocky Man had driven him into the tunnel wall. The bruise had bloomed into a purple continent across his torso, and every breath reminded him he hadn't slept in almost thirty hours. He stopped three metres short of Felix, keeping the exit at his back.

"I don't have the money," Alex said.

Felix's face didn't change. "Then why are you here?"

"Because you're going to take something else."

A dry laugh rattled out of Felix. He dropped the cigarette and crushed it under his boot, grinding it like an afterthought. "I don't do barter, Alex. I do cash. The terms were clear."

"You work for someone," Alex said. "Someone who collects debts. Someone who holds them like weapons."

Felix went very still. The yellow light caught the flicker in his jaw as he clenched it. For a long moment, the only sound was the distant hum of traffic through the warehouse's broken windows.

"Who told you that?"

"Nobody. I worked it out." Alex moved a half-step closer, testing the boundary. Felix didn't retreat. "You're not just a tech consultant. You don't pull data for anyone for free. You told me the debt terms in the same breath you warned me about the camera. Like it was routine. Because it is routine. For you."

Felix studied him with an expression Alex couldn't read. Then he reached into his jacket and pulled out a burner phone — flat, black, anonymous. He held it up between two fingers.

"You know what this is?"

"A phone."

"It's a dead man's switch." Felix's voice was flat. "If I don't type a code into it every six hours, an automatic message goes out to people who would very much like to know where you are. I programmed it myself before you walked through that door."

Alex kept his face neutral. "Then we're both taking a risk."

"Yeah." Felix pocketed the phone. "So let's stop dancing. You're right. The debt isn't mine. I collect it for someone else. Someone who runs a network of debts across London — information, favours, money. They call themselves the Broker."

"The Broker knows about Sentinel."

Felix didn't confirm. He didn't deny. He just stood there, letting the silence stretch, letting Alex fill in the spaces. That was the answer.

"The Broker has data," Alex pressed. "Data that doesn't come from Sentinel's official architecture. Data from before the system was deployed. Data that knows my name."

"I don't know what the Broker knows." Felix's tone turned hard. "I know what I owe. And what I owe is twelve thousand pounds, because you didn't pay me back six years ago and the interest has been compounding through the Broker's ledger ever since."

"Twelve thousand. You said five."

"Five was what you owed me. The Broker adds their own percentage. That's how the system works."

Alex felt the floor shift beneath him. Not literally — but the room spun for half a second as the numbers clicked into place. Felix wasn't running a personal grudge. He was running a collection. The debt was the hook, and the Broker was the line, and somewhere at the end of that line was the source of the hidden feed.

"I don't have twelve thousand pounds," Alex said. "I don't have anything. They took my laptop, my drive, my phone, my wallet. I'm running on stolen cash and a metro card that's about to expire."

Felix spread his hands. "Then we're done."

He turned toward the door, and Alex let him take three steps.

"They'll come for you," Alex said. "Sentinel has a file on you, Felix. I saw it. The Orchard list — your name's on it. You're a suspect. Same as me. Same as Reed. It's been there for years, before any of us ever touched the system."

Felix stopped. His shoulders rose and fell once, a breath he hadn't meant to take.

"The Broker," Alex went on, "might have answers. But if I go to the Broker without you, the Broker will see me as a threat. A stranger with a story. You're the connection. You're the trust. So I'll make you a deal."

He reached into his pocket and pulled out the USB stick. The one Sarah had left under the red umbrella. The one containing the Orchard list — over four hundred names, including Felix's.

"This is the evidence. The entire list. Metadata included. Proof that the system has been profiling people for years without oversight. You bring me to the Broker, and this is yours. You can sell it to whoever you want — a newspaper, a rival agency, a foreign government. I don't care. It's worth more than twelve thousand pounds."

Felix turned around slowly. His eyes fixed on the USB stick in Alex's hand, and for a moment Alex saw something flicker behind them — calculation, hunger, fear. The same hunger Alex had felt when he first saw the list. The pull of forbidden knowledge.

"You found it," Felix said. "Actual proof."

"Hard proof. System admin accounts. A hidden subroutine embedded before launch." Alex held the USB out. "You take me to the Broker tonight, and it's yours. I walk away clean. The debt is settled. You never have to tell the Broker about me."

Felix stared at the drive. His hand twitched at his side.

"Tonight," he repeated.

"Tonight. Before dawn. The system's updating at first light. If I'm still connected to anything Sentinel-touched when that update fires, I'm tagged. We both know what happens next."

Felix took a step forward. Then another. He stopped in front of Alex, close enough that Alex could smell the stale smoke and mint on his breath.

"The Broker doesn't meet with just anyone."

"Make an exception."

Felix reached for the USB. Alex pulled it back a few centimetres.

"After I'm in the room," Alex said. "Not before."

A long pause. The warehouse creaked around them, wind catching a loose panel somewhere in the dark. Felix's jaw worked like he was chewing the decision.

"There's a private members' club in Soho. Upstairs of a betting shop on Old Compton Street. No signage, no listing. You knock three times, then twice, then three again." Felix recited the details like a liturgy. "I'll make the call. If they agree, we go at midnight."

"Who is the Broker?" Alex asked.

Felix's eyes met his. Something shifted in them — a wariness that hadn't been there before.

"I've never seen their face. Only dealt with the calls. But I've heard stories." He paused. "They say the Broker doesn't buy information. They say the Broker collects people. Debtors, sources, assets. And they never let go."

The words settled over Alex like a cold sheet. He thought of Sarah's photograph, stolen from his flat. The only item taken. The Broker collected people.

And someone had wanted Sarah.

Alex pocketed the USB stick and stepped back toward the door.

"Midnight," he said. "Don't be late."

He walked out into the Camden fog before Felix could respond. The warehouse swallowed back into shadow behind him, and Alex felt the burn in his chest sharpen as he pushed through the streets, his mind already racing ahead.

Felix knew more than he was saying. The Broker wasn't just a collector of debts. Whoever they were, they'd known about Sentinel's hidden feed. They'd known about the Orchard list. And now, for the first time, Alex had a name for the puppeteer pulling the strings.

He just had to survive long enough to meet them.
