Chapter 8 - The Checkmate

Ten minutes later, Detective Miller stepped back into the amber-lit interrogation room.
Tristan Vance was still sitting in the exact same posture, checking his watch with a bored, triumphant smirk. "Tick-tock, Detective. Your window is closing. Have you prepared the release papers?"
Miller didn't answer. He walked slowly across the room, carrying a heavy steel evidence box. With deliberate slowness, he set the box down on the metal table, right beside Tristan's unlocked smartphone.
Inside the box lay Tristan's silver key ring, complete with a small, encrypted titanium USB hardware token flashing a faint green LED.
Tristan’s smirk vanished instantly. His eyes snapped from Miller’s face down to the key ring. The color drained from his cheeks as he realized the physical proximity of the hardware token to his active device.
"What did you do?" Tristan hissed, lunging forward across the table.
"Local handshake protocol, Mr. Vance," Miller said calmly, stepping into his path. "Turns out your security architecture had a fatal flaw. You forgot to account for physical proximity."
The green LED on Tristan's smartphone screen flickered twice, turned solid blue, and then flashed a bright, undeniable SYSTEM RESET SUCCESSFUL.
Across the room, the secure terminal pinged as the dead-man's switch server disconnected from the dark-web proxy nodes, locking down every file in a secure federal holding vault before a single byte could be transmitted to the outside world.
Tristan slumped back into his chair, his mask of icy detachment shattering completely. His hands began to shake as he stared at the blank, dead screen of his phone.
"No..." he whispered, his voice cracking with sudden, desperate panic. "No, that's impossible. I wrote the encryption myself. You couldn't have bypassed it."
"You taught me how to look for backdoors, Tristan," Reese's voice echoed softly through the small intercom speaker mounted in the corner of the interrogation room.
Tristan whipped his head around toward the speaker, his eyes wide with disbelief.
"You thought you were the only one building things in that house," Reese's voice continued, steady, cold, and infused with an unbreakable strength. "You thought you could poison me, erase my medical history, and walk away clean. But you underestimated me from the very beginning."
Detective Miller pulled a pair of heavy steel handcuffs from his belt, leaned over the table, and slammed them down onto Tristan’s wrists with a definitive, ringing click.
"Tristan Vance, you are under arrest for the attempted premeditated murder of Reese Vance, the attempted premeditated murder of Maya Vance, and the falsification of federal medical records," Miller recited, his voice echoing off the concrete walls. "You have the right to remain silent..."

As the steel cuffs locked into place around the wrists of the man who had tried to steal her life, Reese hung up the hospital intercom in her sterile ICU room, took a deep, steady breath of clean air, and smiled.
The nightmare was finally over.
