Read Chapter 23: The Product Launch

The conference room smelled like cold coffee and desperation. Camille had stopped noticing the hour two days ago—the clocks on the wall had become decorative, irrelevant to the rhythm of their work. Antoine stood at the whiteboard, marker squeaking as he traced the final architecture of the stripped-down Sentio, the ethical version they'd rebuilt from the bones of Maxime's original code.

"Behavioral inference modules are gone," he said, tapping the diagram. "We're running pure diagnostic analytics. Heart rate variability tracking, sleep pattern correlation, stress markers—nothing that manipulates. Nothing that nudges. Just data the patient owns and controls."

Camille nodded, but her eyes were on the laptop screen. The health ministry's evaluation team would be here in thirty-six hours. Their compliance officer had already flagged three separate provisions in the original Sentio documentation. Three strikes. One more and the contract went to Medtronic's Paris subsidiary, a corporate behemoth that would swallow AlgoSens whole without blinking.

"Camille." Élodie's voice came from the doorway, tentative. "You need to eat."

"I need to ship."

"You need to eat, and then ship." Élodie set a croissant on the edge of the table—from the good bakery, the one near the canal that Camille loved. It was a small kindness, and Camille felt something crack in her chest. Élodie, who was drowning in her brother's debts, still found money and time to bring her a croissant.

"Thank you." Camille took a bite. The flaky pastry dissolved on her tongue, and she realized she couldn't remember her last meal. "How's the financial documentation?"

"Clean. CFO signed off this morning." Élodie hesitated. "He didn't mention the advance."

Camille caught the flicker in Élodie's eyes—the unspoken weight of what that silence had cost. "We'll handle it. After this."

"After this," Élodie echoed, and walked away.

The afternoon dissolved into a blur of testing cycles and deployment scripts. Antoine's team had worked through the night to recompile the diagnostic engine, and by six PM, the first stable build was running. Camille watched the dashboard: 98.7% accuracy on stress detection, false positive rate down to 1.2%. Clean. Defensible. Ethical.

"Launch tomorrow," she announced to the exhausted room. "Full deployment at 0900. We demo for the ministry at 1400."

A ragged cheer went up, followed immediately by someone asking about sleep schedules. Camille didn't answer. There was no time for sleep.

At midnight, she was alone in her office, reviewing the final compliance checklist, when the courier arrived. A man in a blue uniform, holding a thick envelope with a lawyer's letterhead. Maxime's lawyer. Camille's hands went cold as she opened it.

The letter was precise, almost gentle in its legalese. Maxime Duval was willing to testify. He would provide sworn statements about Lucas's involvement in the illegal development of Sentio's manipulation features, about the falsified client trials, about the payments routed through shell companies. He would come out of hiding and face whatever consequences came his way.

In exchange, he wanted one thing: assurance that the stripped-down version of his code—the ethical version, the one Camille and Antoine had built—would be used only for internal audit purposes. Never deployed for client work. Never weaponized.

Camille read the letter three times. Antoine appeared in her doorway, his shirt untucked, dark circles under his eyes.

"What is it?"

She handed him the letter. He read it, then looked at her. "He's asking us to promise not to use his own code commercially."

"Which we already don't plan to do. The ethical version is a different architecture entirely." Camille rubbed her temples. "But he doesn't know that. He's hiding somewhere, terrified, and he thinks we might still ship the original."

"So we tell him yes."

"We tell him yes," she agreed. "We've already stripped the manipulation algorithms. But Maxime doesn't need to know that. If he believes his code is still in play, he has a reason to testify against Lucas—to protect himself from the fallout."

Antoine's eyes narrowed. "You're saying we lie to him."

"We're saying we give him what he needs." Camille met his gaze. "His testimony is worth more than his peace of mind. Lucas has a board seat, a stake in the company, and a threat hanging over my head. Maxime is the only person who can tie Lucas directly to the fraud."

"And what happens when he finds out we never used his code?"

"Then we have a witness who's already testified, and a product that's already launched, and a story that's already been told." Camille's voice was steady. "By the time he learns the truth, it won't matter."

Antoine was silent for a long moment. Then he nodded. "I'll draft the response. But Camille—we're walking a line here."

"I know." She looked at the laptop, at the clean code running her dashboard. "We're walking it together."

They replied to the lawyer within the hour, agreeing to Maxime's terms. The response was immediate: Maxime's testimony would be recorded in two days, delivered directly to Sarah Moreau. The data room would be complete.

Camille should have felt relief. Instead, a cold knot settled in her stomach. Something about the letter was too perfect. Too convenient.

It was Antoine who found the problem. At three AM, he burst into her office, his face pale.

"Camille. You need to see this."

She followed him to the server room, where he'd pulled up the deployment logs for the ethical version. There, buried in the code—deep in the diagnostic engine, in a module that supposedly only collected raw health data—was a backdoor.

"Maxime planted it," Antoine said, his voice tight. "A remote access point. If he sends the right signal, he can shut down the entire system. Every deployment, every client, every patient currently using Sentio. He can kill it all from wherever he's hiding."

Camille stared at the screen. The backdoor was elegant, disguised as a routine health data sync protocol. It would have gone undetected in any standard audit. Only someone looking for it—someone who knew Maxime's coding patterns the way Antoine did—would have found it.

"He wanted insurance," she said slowly. "He agreed to testify, and he built in a way to control us if he changed his mind."

"Or if he doesn't trust us." Antoine ran a hand through his hair. "We can remove it. Patch the module, shut the access point down."

Camille was already shaking her head. "No. If we remove it, Maxime will know. He'll retract his testimony, go back into hiding, and we lose our only witness against Lucas."

"So we leave a backdoor in our own product?"

"We leave it." Camille's mind was racing. "But we know it's there. And he doesn't know we know."

Antoine stared at her. "You're planning to use this."

"I'm planning to have leverage." She turned to face him. "Maxime can shut down Sentio remotely. But if he does, he exposes himself—he's just agreed to testify, to come out of hiding. A remote shutdown would be traceable. We'd have proof of his actions. He'd be implicating himself in the very fraud he's trying to escape."

"And if he doesn't care? If he's willing to burn everything?"

"Then we remove the backdoor before he can use it, and we release the evidence that he planted it in the first place." Camille's voice was flat. "Either way, we control the narrative."

Antoine was quiet for a long moment. When he spoke, his voice was low. "This isn't who you were a month ago."

"I know." Camille looked at the screen, at the hidden code that could destroy everything they'd built. "But a month ago, I didn't have anything worth protecting."

She didn't say the rest—that Antoine was part of what she was protecting now. That his presence had changed the calculus of everything. That for the first time in years, she was fighting for something beyond her own survival.

Instead, she said, "Launch is in nine hours. Do we ship with the backdoor in place?"

Antoine studied her. Then he nodded slowly. "We ship. But we build a kill switch of our own—a way to close his access point if he moves."

"Can you do it without him noticing?"

"I can try." He turned back to his terminal. "I'll need six hours."

"You have five."

Dawn broke over Paris as they finished. The code was live, the backdoor still in place, Antoine's kill switch buried in the same module, nearly identical in structure—a mirror image no one would notice unless they were looking for both.

Camille stood at the window, watching the first light touch the rooftops. The city was waking up, unaware that everything was about to change.

Behind her, Antoine's phone buzzed. He picked it up, his face going pale.

"Camille." His voice was strained. "Sarah just called. She's heard from a source—she says there's an article about to drop. About the fabricated metric. About you."

Camille's blood went cold. Thursday wasn't until tomorrow.

But Lucas had moved early.
