Chapter 9
The piercing shriek of the smoke detector echoed off the tile walls, its intermittent flashing red light casting an urgent pulse across the kitchen. Mark covered his ears for a second before grabbing a kitchen chair and pulling it beneath the ceiling unit. He climbed up, unscrewed the plastic cover with a butter knife, and pulled out the internal circuit board. It wasn't wired for smoke detection at all; instead, a modified receiver chip was soldered directly into the speaker terminals, pulsing with a steady stream of incoming data packets.
"It’s a repeater," Mark said, holding the charred circuit board down toward Sarah. "They’ve been using our house as a relay station for the regional network. Every time we had a conversation in the living room, every time Leo spoke... it was being broadcast straight to their servers."
Sarah clutched the silver flash drive in her fist, her knuckles white. "That's why they aren't worried about the police. They control the entire local infrastructure. If we call 911, the call gets routed through their switchboard in Sector 4."
Leo stood near the refrigerator, kicking a small, discarded piece of gray towel across the floor with the tip of his shoe. "The big gate is open," the toddler said, his voice returning to its normal innocent pitch, though his eyes remained unnervingly focused on the dark hallway leading to the basement.
Mark climbed down from the chair, setting the modified circuit board on the counter. "We need to get out of here through the back garage door. Even if the deadbolt is jammed on the front, the manual release on the garage hasn't been tied into their system."
"And go where?" Sarah asked, her voice cracking as she looked around the kitchen that had been their sanctuary for three years. "If Vance’s people have been tracking Leo’s cognitive patterns, they know every route we take before we even pick the keys up."

"To the forest coordinate," Mark said firmly, pulling the leather journal from Sarah's grip and flipping to his father’s final handwritten note. "My dad hid a physical analog backup of the audit twenty years ago when he worked on the initial zoning permits for that land. It’s the one thing their digital servers can't reach."
As Mark reached for the garage interior door, the overhead light flickered once, twice, and then went completely dark, plunging the house into absolute shadow except for the blinking red light of the flash drive still resting on the counter.
