Chapter 3 - The Ghost in the Machine
The morning sun crept across the Chesapeake Bay, painting the sky in pale shades of amber and rose, but inside the Brooks home, the atmosphere remained glacial. Owen woke up cheerful, his spirits surprisingly high now that the heavy, intimidating exoskeleton was offline. For breakfast, he ate pancakes with his father, laughing at a bad joke Nathan made about the coffee pot.
Watching them together, my heart squeezed. Nathan was a good father—strict, disciplined, but fiercely protective. The loss of Claire had scarred them both, leaving Nathan with a desperate need to fix everything that was broken in his son’s world. He couldn't fix the accident, but he could buy the best technology money could buy. Or so he had thought.
After breakfast, Nathan called me into the kitchen while Owen was watching cartoons in the den.
"We need a neutral expert," Nathan said, sliding a cup of black coffee across the granite island. "Someone whose credentials StrideCore's legal team can't dismiss as a biased nurse or an angry father."
"Who do you have in mind?" I asked.
"Dr. Aris Thorne," Nathan replied. "He used to head the biomedical robotics division at Johns Hopkins before he retired from academia to consult independently. He testified against major medical device manufacturers three years ago in the spinal-stimulator scandal. He’s brilliant, incorruptible, and he hates corporate negligence with a passion."
"Can we reach him?"
Nathan pulled out a weathered, military-grade satellite phone. "I served with his younger brother in the Gulf. I’ll make the call."
By noon, Dr. Thorne had agreed to look at the data files we securely transmitted to his encrypted server. Within two hours, his video call popped up on Nathan’s laptop.
Dr. Thorne appeared on screen, a silver-haired man with sharp eyes behind wire-rimmed glasses, sitting in a study lined with thick leather-bound medical journals.
"Admiral, Ms. Hayes," Thorne began without pleasantries. "I’ve spent the last ninety minutes reviewing the raw EEPROM dump and the firmware revision history you sent over. I wish I could tell you you're mistaken."
Nathan leaned forward, his hands flat on the table. "Give it to me straight, Doctor."
"The X9 unit Owen is wearing uses a differential gear system paired with a brushless DC motor," Thorne explained, bringing up a 3D schematic on his end. "To save weight, StrideCore used a composite housing that flexes under heavy lateral loads. When the knee flexes past thirty degrees under a load exceeding forty pounds, the housing twists by less than a millimeter. That micro-twist throws off the optical encoder."
"And the machine thinks the leg is failing," I said, connecting the dots.
"Exactly," Thorne nodded. "So the safety protocol triggers an instant, hard lock to prevent the knee from buckling backward. But because of the flawed firmware architecture, the system interprets its own structural error as user resistance, locks up tight, and then automatically logs the incident as a user positioning fault to clear itself of liability. It's a closed-loop cover-up."
Nathan's jaw tightened so hard I thought I heard bone grind. "They knew the housing warped."
"They knew," Thorne confirmed. "There’s an internal memo referenced in the header files from their chief materials engineer dated two years ago. They were warned that the carbon composite was too brittle for high-impact pediatric rehabilitation. They shipped it anyway."
"Thank you, Doctor," Nathan said stiffly. "We’ll be in touch."
As the call ended, Nathan stood up so fast his chair scraped loudly against the hardwood floor. He walked over to the window, staring out at the driveway where the empty space waited for a car that would never come back.
"Four hundred thousand dollars," Nathan murmured, his voice shaking slightly. "Not for my son's health. For their profit margin."

"Nathan," I said softly, stepping closer. "What do we do now?"
"We don't call lawyers yet," Nathan said, turning around, his eyes flashing with cold, tactical resolve. "Lawyers take months. Depositions take years. StrideCore's legal team will bury us in NDAs and arbitration clauses. We need to force their hand publicly, on our terms."
