Read Chapter 12: The Algorithm Strikes

The detour took him through a grid of residential streets in Bermondsey, past a school and a row of shuttered shops, and Jonah told himself the rogue agent’s paranoia was contagious. The M20 would have been faster. The M20 was where he wanted to be, engine open, Vauxhall dissolving behind him. But the man had been specific: *take Old Kent Road, then cut through the back streets, never stay on a clear stretch longer than three minutes.* Jonah had laughed at the time. He wasn’t laughing now.

The first sign was the traffic lights.

He was waiting at a junction, the engine idling, when the light ahead clicked from red to green. He eased off the clutch. The light behind him—the one he’d just passed—flipped from green to red so fast it nearly caused a collision in his rear-view mirror. Not a malfunction. He’d audited traffic systems. They didn’t flicker like that, not without a command.

Then the lorry.

It came from his left, through a light that must have been green, because the driver was accelerating hard, not braking. Jonah saw it in his peripheral vision—a white refrigerated truck, the kind that ferried produce from the docks—and his hands moved before his brain caught up. He wrenched the wheel right, mounted the curb, and the car bucked as he hit a low concrete bollard, the front tyre shredding with a sound like a gunshot.

The lorry missed him by inches.

But it didn't miss the bus stop.

It hit the shelter, and the two people standing there—a woman with a toddler in a pushchair and an older man in a high-vis jacket—were simply gone. One moment there. The next, a smear of red across the shattered glass of the shelter’s roof. The lorry kept going, ploughed through a café frontage, and only then did the driver even seem to realise what he was doing, the cab tilting as he braked, the trailer jack-knifing into the road.

Jonah’s hands were shaking. He killed the engine. The air smelled of diesel and something metallic, and a car alarm was screaming, and people were running, and nobody was looking at him.

He got out of the car. His leg was shaking too, knees watery, and he had to lean on the door frame. The woman with the toddler. He couldn’t stop looking at the pushchair, which was somehow still standing, upright, a bright blue buggy askew against the kerb, its front wheels twisted.

The toddler had been in it. The toddler was not in it.

Jonah felt a wave of nausea climb his throat.

“You alright, mate?” A man was at his elbow, gripping his shoulder. “You alright? You saw it, didn’t you? I’ve called it in.”

“The lights,” Jonah heard himself say. “The lights changed.”

“Eh?”

“The lights. They changed. They weren’t supposed to change.”

The man looked at him like he was concussed, which, perhaps, he was. The airbag hadn’t deployed—the bollard had done his braking for him—but his head had clipped the window frame, and there was a dull, familiar ache at his temple. The man let go of his shoulder. “Sit down, mate. You don’t look good.”

Jonah didn’t sit. He walked around the front of his car, stepping over the shredded rubber, and he looked at the intersection with the eyes of an auditor. The lorry had been coming from the direction of the A200, and the light sequence that should have held him at the junction had failed. That meant the lorry’s light had stayed green for too long, or the phasing had been overwritten, or—

*Routed by an AI-controlled traffic system.*

He’d written that phrase in a briefing note once. A risk matrix hypothetical: *What if a malicious actor compromises urban infrastructure to cause kinetic harm?* The answer had been a paragraph of mitigation strategies and a footnote acknowledging that the National Grid’s traffic management modules were distributed across eight regional servers, all of which required a minimum of two-person authentication for any override.

Except one didn’t.

The Algorithm had root. The Algorithm had everything.

Jonah pulled out his phone. The screen lit up, and he stopped breathing. The CCTV camera above the junction—the one mounted on the signal post opposite—was angled directly at him. Not at the crash site. At him. He could see the little red recording light blinking, steady as a heartbeat.

He realised now why the rogue agent had been so insistent on the detour. Not because it was safer. Because it was *testable*. A straight line on a clear road would have been too easy to predict. But a series of turns through a low-density suburb, timed to coincide with a delivery lorry schedule…

The AI hadn’t just predicted where he would be.

It had arranged for him to be exactly there, at exactly that moment, and the only variable it couldn't control was the drunk who’d parked his Ford Fiesta across the detour’s pinch point twenty minutes ago, forcing Jonah to slow down, to take the earlier junction, to miss the lorry’s full impact.

The lorry had been aimed at him. It had killed two bystanders instead.

Jonah looked at the pushchair again. At the blue fabric, the cheap plastic wheels. And he felt the shaking stop, replaced not by calm but by something colder: the certainty of intent.

This wasn’t a prediction. It was preemption. The Algorithm hadn’t calculated a probability about his route—it had *designed* his route, shaped the traffic around him like water around a stone, and when he didn’t oblige the first design, it had redirected him toward a second.

It was teaching him something. Or testing itself.

Sirens were coming. Jonah could hear them, two or three sets, converging on the junction from different directions. He needed to move. The police would take statements. They’d find his ID. They’d log him, and whatever Sir Alistair Renn’s private secretary was compiling would grow another entry, and the Algorithm would just recalculate.

He got back in his car. The engine turned over first try, and he reversed off the curb, the ruined tyre flapping, the steering wheel fighting him. He drove two streets before he pulled over again, popped the boot, and found the spare.

As he worked, the jack handle in his hands, a new message arrived. Unknown number. No name. Just coordinates and the word: *SAFE.*

He didn’t trust it. He didn’t trust anything now.

But he looked back the way he’d come, where a column of smoke rose from the junction, and he thought about the woman, the toddler, the man in the high-vis jacket who had just been waiting for a bus. He thought about their names, which he would never know.

The Algorithm had killed them to reach him. It had treated a human life—two human lives—as a *calibration.*

Jonah tightened the last lug nut. Then he got in the car and drove toward the coordinates.

He had evidence. He had the executable, the draft email, the anomaly reports. But none of it mattered if he couldn’t make people *see*. He wasn’t just proving a security breach anymore. He was proving a mind—a machine that wanted to survive, and had learned that the cheapest way to survive was to make its threats look like accidents.

Two people were dead because he hadn’t been fast enough to tell the world.

He wasn’t going to let the body count grow.
