A $400,000 ROBOT knee locked while a nine-year-old boy was walking, and I caught him just before he hit the floor. But someone had already tampered with the evidence that would have exposed the truth.

The darkness inside the garage was absolute for three suffocating seconds before the emergency generator clicked and bathed the room in pale amber standby light. Outside, the gravel driveway crunched under the deliberate, heavy tread of approaching tires.

"Stay down," Nathan commanded. The grief-stricken father vanished, instantly replaced by a combat commander who had spent thirty years directing naval strike groups. He moved to the reinforced gun safe behind the tool cabinet, input a six-digit code, and pulled out a standard-issue SIG Sauer P229.

I quickly ejected the encrypted USB drive containing the partial dump of the StrideCore telemetry and tucked it deep inside the inner lining of my canvas medical bag. Across the workbench sat my own prototype—a purely mechanical, non-powered brace crafted from lightweight aircraft aluminum, high-grade carbon composite, and oil-damped hydraulic hinges. It didn't have microprocessors, Bluetooth modems, or remote cloud overrides. It worked on pure physics, geometry, and the natural biomechanics of human anatomy.

"Nathan, look at the security monitors," I whispered.

On the secondary terminal, the external night-vision feed showed a black, unmarked Chevrolet Suburban idling at the foot of the Brooks driveway, its headlights completely blacked out. Two figures in tactical weather gear had dismounted and were approaching the side gate with an electronic RF-jamming wand and a lock-bypass kit.

"Corporate recovery team," Nathan said through clenched teeth. "Victor Lang isn't taking chances. If that unit stays in my custody and undergoes an independent forensic teardown by the Department of Defense, StrideCore loses their five-hundred-million-dollar defense procurement contract next month. They're here to repossess the exoskeleton under the guise of an emergency mandatory safety recall."

"They can't legally enter your private property," I said.

"They won't claim they broke in. They'll claim the lithium-polymer battery inside the suit showed signs of thermal runaway and they acted under exigent circumstances to prevent a residential fire." Nathan checked the chamber of his sidearm. "They didn't anticipate you isolating the telemetry logs before they could wipe the hard drive."

Upstairs, a floorboard creaked. Owen's faint, frightened voice drifted down through the ventilation shaft. "Dad? Lauren? The lights went off..."

My heart slammed against my ribs. "Owen is up."

"Get to him," Nathan ordered, opening the side service door leading to the interior stairwell. "Take Owen out through the storm cellar in the back garden. My driver, Master Chief Alvarez, is stationed two miles north at the naval auxiliary depot. I'll draw these operators toward the front foyer."

"Nathan, you can't engage them alone!"

"This is my house, Lauren. And that boy is all I have left of Sarah." Nathan’s eyes locked onto mine with fierce, unyielding resolve. "Take your mechanical brace. If they take the StrideCore suit, Owen needs to be able to move. Do not stop for anything."

I didn't hesitate. I grabbed the canvas medical kit, slung the lightweight mechanical brace over my shoulder, and bolted up the darkened stairs.

I pushed open Owen's bedroom door. The nine-year-old was sitting upright in bed, clutching a faded fleece blanket that had belonged to his mother. His thin legs were motionless under the sheets.

"Lauren?" he whispered, his big brown eyes reflecting the dim moonlight streaming through the window. "Is the bad robot back?"

"No, sweetheart," I said, lifting him gently into my arms. He was painfully light, his muscles having atrophied over months of confinement and failed robotic therapy. "We're going on a little adventure tonight. Just you, me, and the new brace I built for you."
