3. The Neighborhood Watch

The house in Ballard belonged to Claire’s sister, Marlene, a high school physics teacher who had inherited it from their parents and filled it with bookshelves and half-finished crossword puzzles. It was a narrow two-story on a street lined with sugar maples, the kind of street where children drew chalk hopscotch grids on the sidewalk and neighbors waved from porches. By the time Ethan arrived with the evidence from Marcus Webb’s condo, the house had transformed into something else entirely: a bunker disguised as a home.

Peter Kohl arrived at eight o’clock that evening. He was a thin, angular man in his late fifties, with a salt-and-pepper beard and the weary eyes of someone who had spent decades filing Freedom of Information requests that went nowhere. He had been a reporter at the Millfield Gazette for twenty-three years, long enough to see the newsroom shrink from forty journalists to six, long enough to have his investigative instincts dulled by the grind of rewriting press releases. But Claire had known him during her brief stint as a layout designer, and she had always said Kohl was one of the few reporters left who still believed that journalism was a public trust rather than a content mill.

Kohl sat at Marlene’s dining table, a cup of black coffee cooling at his elbow, and listened without interruption as Ethan laid out the evidence. The intervention spreadsheet. The Foundational Principles manifesto. The red envelopes stamped with the word DENIED. The transfer authorization signed by Richard Ashford, Aegis Mutual’s COO, with its chilling directive to “cleanse per established protocols.” Ethan spoke for nearly an hour, his voice hoarse, pausing only when Claire interjected with a detail he had forgotten or when Lily, sitting rigidly on the staircase, shifted her weight and made the old wood creak.

When Ethan finished, Kohl was silent for a long time. He picked up the stamp—the heavy wooden handle, the etched rubber base—and turned it over in his hands.

“I’ve been covering Millfield for two decades,” he said finally. “I’ve reported on zoning disputes and school board meetings and the occasional embezzlement scandal. I’ve never seen anything like this. And I want to believe you. The problem is, what you have here is a pile of internal documents that no one outside this room can verify. The spreadsheet could be fabricated. The manifesto is philosophical, not operational. The envelopes are damning, but they’re circumstantial. Ashford’s signature on a vague authorization isn’t a confession to murder.”

“What about the list of names?” Ethan asked. “Hundreds of people, all dead, all denied coverage first?”

“Correlation isn’t causation in a courtroom,” Kohl said. “Aegis denies thousands of policies every month. Some of those people will die—that’s the actuarial math your own profession is built on. A prosecutor would need to show a direct link between a specific denial and a specific killing. You haven’t got that yet.”

Claire’s voice cut through the room. “Then what do we need?”

Kohl set down the stamp and rubbed his eyes. “You need a source inside the operation. Someone who can testify to the connection between the algorithm’s output and the actions taken on the ground. You need a Nullum operative, or a Special Risk Mitigation employee who’s willing to talk. Without that, this is a conspiracy theory with nice graphics.”

The word “Nullum” hung in the air. Ethan realized he had not yet explained that part to Kohl—the organization behind the interventions, the regional directors Webb’s document had referenced. He pulled out the transfer authorization and pointed to the line: “Liaise with Nullum regional directors for jurisdictional coordination.”

“Nullum,” Ethan said, “is the group that does the actual killing. Aegis provides the data, the risk scores, the target list. Nullum carries out the sentences. I don’t know how big it is, or where it came from, but Webb’s documents reference regional directors. Plural. That means it’s spread across multiple jurisdictions. This isn’t just happening in Millfield.”

Kohl leaned forward, his weariness replaced by the faintest spark of the reporter he used to be. “If that’s true, then the story is bigger than Aegis. It’s bigger than this town. But it also means you’re not just up against a corporation. You’re up against a network of people whose entire purpose is making problems like you disappear.”

The conversation was interrupted by Lily’s voice, small and brittle from the staircase. “Dad? Can I talk to you? Alone?”

Ethan excused himself and followed his daughter into the small bedroom Marlene had prepared for her. The room was painted a pale lavender, with a quilt covered in stars folded at the foot of the bed. Lily sat on the edge of the mattress, her knees drawn up to her chest. At fifteen, she was caught in that liminal space between childhood and adulthood, her face still round with softness but her eyes carrying a new, unwelcome sharpness.

“I heard you talking,” she said. “About the algorithm. About my name being in the system.”

Ethan sat beside her. He wanted to lie, to offer the easy parental comfort that everything would be fine, but the past forty-eight hours had stripped him of that privilege. “Yes,” he said. “Your name is in there. It’s a mistake, Lily. It’s a broken machine making broken decisions. We’re going to fix it.”

“That’s not what I wanted to talk about.” Lily pulled her phone from her pocket and unlocked the screen. “At school, two weeks ago, we had an assignment in English class. We were supposed to write a persuasive essay on a social issue. I wrote about the surveillance state. About how governments and companies collect data on people and use it to control them. I cited Orwell. I cited Snowden. I got an A.” She handed Ethan the phone. “Yesterday, someone posted the essay on the Millfield Community Forum. The comments are... look at the comments.”

Ethan took the phone and scrolled. The forum was a local message board, the kind of digital town square where residents debated pothole repairs and reported lost cats. Lily’s essay had been posted by an anonymous account, and beneath it, a torrent of responses had accumulated. The top comment read: “This is exactly the kind of subversive thinking that needs to be flagged. If she’s anti-surveillance, what is she trying to hide?” Another: “The insurance companies know what they’re doing. If they flag someone, there’s a reason.” And further down, a comment that made Ethan’s stomach clench: “Prevention is better than cure. If the algorithm says she’s a risk, I trust the algorithm.”

The comments were not the work of trolls or bots. The usernames matched real people—Ethan recognized several from the neighborhood. Mrs. Calloway, the woman who had spoken to the reporter outside Gregory Dunn’s house, had written: “We need to trust the systems that protect us. My husband was denied coverage last year and we accepted it. Some people just can’t handle being told they’re a danger.”

Ethan looked up from the phone. “This is the familial vector Webb was talking about. Your essay. The algorithm flagged it as subversive ideation. It’s using sentiment analysis to predict future behavior.” He felt a cold fury building, a rage not just at the system but at the community that had so eagerly embraced it. “Your English teacher—who graded this?”

“Mr. Hennessy. He’s the one who encouraged me to submit it to the school literary magazine. He said it was important for young people to think critically about power.” Lily’s voice cracked. “Did he report me?”

“Maybe not intentionally. The Cassandra system pulls data from everywhere—school servers, social media, public forums. If your essay was stored on the school’s cloud, the algorithm could have scraped it automatically.” Ethan handed the phone back. “But someone leaked it to the forum. Someone wanted the community to see it.”

From downstairs, Kohl’s voice rose in a sudden exclamation. Ethan and Lily hurried back to the dining room to find the reporter staring at his own laptop, his face pale.

“I started digging into the names on your spreadsheet,” Kohl said. “The ones marked resolved. I cross-referenced them with obituaries from the past eighteen months in Millfield and the surrounding towns. The deaths are all there, every single one. But here’s what’s interesting—in the past three months, the rate has increased. Dramatically. And the demographics have shifted. It started with people who had criminal records, even minor ones. Then it moved to people with mental health histories. Now it’s flagging people based on ideological markers. Political affiliations. Reading habits. The kind of books they check out from the library.”

He turned the laptop around to show a graph he had hastily assembled. The line climbed steadily through the first fifteen months, then spiked sharply upward in the last ninety days. “Something changed recently. They’re accelerating. And they’re broadening the criteria.”

Ethan thought of the entry on the Project Certainty interface: “Phase IV expansion authorized.” The expansion Webb’s documents had referenced. This was not a static program; it was growing, evolving, consuming more and more of the population in its maw.

A knock at the door froze them all.

Marlene, who had been sitting quietly in the corner throughout the discussion, rose and walked to the front window. She parted the curtain an inch and peered out. “It’s a woman,” she said. “Mid-fifties, maybe. Well-dressed. I don’t recognize her.”

Ethan moved to the window and looked. The woman on the porch was tall and elegant, with silver-streaked hair pulled back in a severe bun. She wore a charcoal pantsuit and carried a slim leather briefcase. She looked like a lawyer, or an executive, or something in between. She did not look like a Nullum operative—but then, Ethan realized, he had no idea what a Nullum operative looked like. The whole point was that they looked like everyone.

“Don’t open the door,” Claire said.

But the woman had already seen movement through the window. She raised her voice, clear and calm. “Mr. Cole? My name is Dr. Helena Vance. I believe you’ve been looking into my work. I’d like to talk.”

The name hit Ethan like a physical blow. Helena Vance. The chief actuary. The author of the Foundational Principles manifesto. The architect of Cassandra herself. She was standing on Marlene’s porch as if she had been invited to dinner.

“How did you find us?” Ethan called through the closed door.

“I’m not here in an official capacity,” Vance said. “If I were, you wouldn’t have received a courtesy knock. Please, Mr. Cole. I know what you took from Webb’s condo. I know what you think you understand. I’m here because I believe you deserve the full picture before you make decisions that will have consequences for your family.”

Kohl looked at Ethan and mouthed: “Let her in. This is your source.”

Claire shook her head violently, her arms wrapped around Lily. But Ethan understood that Vance was right—if she had come with hostile intent, there would have been no knock. And Kohl was right too. The architect of the system, speaking on the record, was evidence no spreadsheet could match.

He unlocked the door.

Helena Vance stepped inside with the composed grace of a woman accustomed to commanding rooms. She declined Marlene’s offer of coffee with a slight inclination of her head and took a seat at the dining table, her briefcase resting on her lap. Up close, she was older than she had appeared at the company gala two years ago, deep lines etched around her mouth and eyes. But her gaze was steady and unnervingly direct.

“I know this must seem terrifying,” she began. “The documents, the interventions, the list with your family’s name on it. I understand the impulse to expose it all, to bring the machinery into the light and trust that justice will follow. But I’m here to ask you to stop. Not for Aegis’s sake. For yours.”

“You’re asking me to stay silent while your algorithm murders people,” Ethan said.

“I’m asking you to understand the context before you act.” Vance opened her briefcase and withdrew a tablet, which she placed on the table. The screen displayed a map overlaid with thousands of tiny red dots, each representing an actuarial risk assessment. “Cassandra was not designed to be a weapon. It was designed to be a mirror—a reflection of the statistical truths that society prefers to ignore. Every human being carries a probability of harmful behavior. Most people cluster at low probabilities. A small percentage cluster dangerously high. Insurance has always been in the business of sorting these populations, but we only ever sorted them after the fact. Cassandra allows us to sort them before.”

“And Nullum turns your sorting into a death sentence,” Claire said.

Vance’s expression flickered, a micro-flinch that Ethan might have missed if he had not been watching her so closely. “Nullum was not my creation. It was a consequence I failed to anticipate. When the Phase I results showed a ninety-four percent reduction in claims payouts in test regions, certain parties became very interested. Parties outside the company. They saw in Cassandra not a tool for financial efficiency but a tool for social engineering. They appropriated the model and built an enforcement arm. By the time I understood what was happening, the machine was already running on its own momentum.”

“You’re telling us you lost control of your own creation,” Kohl said. “That’s not a defense. That’s an admission of negligence.”

“It’s both,” Vance said. “And I’ve spent the last year trying to regain control. But the situation is more complex than you realize. Nullum is not a rogue cell of vigilantes. It has funding. It has political cover. There are people in positions of authority who believe—genuinely believe—that what Nullum is doing is necessary. They look at the crime statistics in intervention zones and see salvation. They’ve seen the future and found it safer.”

Ethan thought of the comments on Lily’s essay. Mrs. Calloway, trusting the algorithm. The anonymous voices celebrating prevention over cure. The social fabric of Millfield was not being torn apart by terror—it was being rewoven into something new, a community that policed itself by embracing the machine that policed it.

“Why are you here?” Ethan asked. “If you can’t stop it, and you’re not going to expose it, what do you want from us?”

Vance met his eyes. “I’m here because your daughter’s risk score is a mistake. Not morally—the algorithm doesn’t make moral mistakes—but procedurally. The sentiment analysis that flagged her essay was calibrated for adult offenders, not adolescents writing academic assignments. The language model over-indexed on rhetorical markers associated with anti-authoritarian radicalization. It’s a bug, not a feature. I can correct it. I can remove her from the queue.”

“In exchange for what?” Claire’s voice was ice.

“In exchange for your silence. Give me the documents you took from Webb. Walk away from the story. I will ensure your family is designated as Excluded—the same status that protects Aegis executives and their loved ones. Lily will be safe. You and Claire will be safe. You can return to Millfield, resume your lives, and pretend none of this ever happened.”

The offer hung in the air, a devil’s bargain dressed in the language of protection. Ethan looked at his wife, at his daughter, at Kohl, whose face was unreadable. He thought of the hundreds of names on the intervention spreadsheet, the red pins on the map, the people whose risk scores would not be corrected because no one had broken into a field director’s condo to steal evidence on their behalf.

“And everyone else?” Lily asked. Her voice was quiet but steady. “The other people on the list. The ones whose essays got flagged, or whose library books got flagged, or whose mental health history got flagged. What happens to them?”

Vance’s silence was answer enough.

Ethan realized, in that moment, that Vance was not a villain in the traditional sense. She was something more dangerous: a true believer who had glimpsed the consequences of her belief and decided the cost was acceptable. She had come to offer him a lifeboat, and she genuinely believed she was being generous.

“I need time to think,” he said.

“You don’t have time,” Vance replied. “Webb knows his condo was breached. He filed a report this afternoon, and the Nullum regional director has authorized an expedited intervention on your file. You have until Friday—less, if they decide to accelerate further. My offer expires at midnight tomorrow. After that, your family is back in the queue, and I won’t be able to protect you even if I wanted to.”

She stood, gathered her tablet, and walked to the door. Before leaving, she turned and looked at Lily with an expression that might have been regret or might have been mere calculation. “Your essay was excellent,” she said. “It’s a shame it was read by the wrong audience.”

The door closed behind her, and the house fell into a weighted silence.

Kohl was the first to speak. “She just gave you the story. On background, but still. The chief actuary admits the algorithm is being used for extrajudicial killings. She admits political cover. She admits the bug that flagged your daughter. If I can get even a fraction of that confirmed through other sources—”

“She’ll deny everything,” Ethan said. “She came here alone, no witnesses. It’s our word against hers, and she’s the respected scientist while I’m the disgruntled employee who stole company documents.”

“Then we get her on the record,” Kohl said. “Secretly. A recording, a follow-up meeting with a hidden camera. Something.”

But Ethan was no longer listening. He was staring at the tablet Vance had left behind, forgotten on the edge of the table. She had been so careful, so composed, but in her haste to leave she had made a mistake. The tablet was still unlocked, its screen displaying a directory of files. At the top of the directory was a folder labeled “NULLUM — REGIONAL CONTACTS.” Beneath it, another: “PHASE V PROPOSAL — PENDING BOARD APPROVAL.”

He opened the first folder. Inside was a map of the country, divided into colored regions, each with a director’s name and contact information. The eastern region, which encompassed Millfield, was assigned to someone named “Aldric Voss.” The western region to “Serena Cho.” The southern to “Malcolm Greer.” Each name was hyperlinked to a profile page with photographs, biographies, and operational histories.

“Phase Five,” Claire said, reading over his shoulder. “What’s Phase Five?”

Ethan opened the second folder. The document inside was dated three weeks earlier and bore a watermark reading “CONFIDENTIAL — BOARD REVIEW ONLY.” Its executive summary was brief and devastating: “Phase V proposes the expansion of pre-delinquency protocols from individual targeting to demographic cohort analysis. By identifying community-level risk factors—socioeconomic indicators, educational attainment, geographic clustering of flagged individuals—Nullum can conduct proactive cleansing operations at scale. Initial projections suggest a 78% reduction in crime within intervention zones, with collateral risk confined to acceptable parameters.”

Demographic cohort analysis. Community-level risk factors. Ethan understood what he was reading, and the understanding opened a pit beneath him. Phase V was not about targeting individuals anymore. It was about targeting neighborhoods. Whole communities identified as high-risk and subjected to “cleansing operations at scale.” The quiet streets of Millfield were not just a hunting ground—they were a laboratory.

And then he saw the final page. It was a map of Millfield, overlaid with census data and color gradients indicating risk density. Several neighborhoods were highlighted in yellow, indicating “elevated community risk.” But one area was outlined in pulsing red, with a notation beside it: “Priority Cohort A — Intervention Window: Q4. Estimated cleansing yield: 2,400-3,100.”

The red outline encircled Sycamore Lane, the neighborhood school, the community park, the strip mall where Ethan had sat in his car reviewing stolen documents. It encircled his home. It encircled Marlene’s house in Ballard, which sat just inside the boundary of the designated priority zone.

The algorithm had moved beyond individuals. And the entire community was now in its crosshairs.
