Chapter 4 - THE THERMAL OVERRIDE

The silence of the house was gradually replaced by the aggressive, roaring hum of the heating units. Hot air began to whistle through the brass floor vents, carrying the smell of scorching dust and hot metal.
In his office, the clatter of Julian’s keyboard stopped abruptly.
Clara stood in the dark corridor, tucked into the recessed alcove of the linen closet. Through the gloom, she watched his office door swing open. Julian stepped out, his sweater already pulled off, wearing only his white t-shirt and trousers. His forehead was slick with sweat, his brows furrowed in confusion and irritation as he looked down at the wall-mounted thermostat panel in the hallway.
The digital display was flickering erratically, showing red warning icons: THERMAL RUNAWAY // OVERRIDE ACTIVE.
"What the hell?" Julian muttered to himself, tapping the glass screen repeatedly. The screen didn't respond; the hardwired bridge Clara had created bypassed the software entirely.
He reached into his pocket, pulled out his phone, and opened his administrator app. But because Clara had bridged the analog line, the software showed the system as offline for safety reasons. The smart lock system was already registering the rising heat as a potential fire event, initiating a pre-alarm countdown.
If the internal temperature stayed above forty degrees for ten minutes, the house's smart locks would automatically release their magnetic pins to allow emergency responders entry—a standard safety feature required by Oslo building codes.
Julian cursed under his breath. He knew the system architecture. He knew that the only way to kill the override before the locks released and alerted the local monitoring service was to manually pull the master fuse down in the basement workshop.
He turned toward the basement stairs at the end of the hall, his slippers slapping against the floor with uncharacteristic haste.
Clara waited three seconds after his shadow disappeared down the cellar stairwell before she moved.
She didn't run to the front door. She knew the magnetic pins hadn't released yet, and the main door was still deadbolted. Instead, she slipped back into the master bedroom, snatched her black suitcase from the bed, and unzipped the lining completely.
She pulled out a small, heavy steel tool—a hardened pry bar she had hidden in the frame of the luggage weeks ago when she first began to suspect Julian was monitoring her financial statements.
She walked to Julian’s office.
The room smelled of stale coffee and expensive leather. His laptop sat open on the mahogany desk, its blue screen displaying a complex command terminal window with lines of green code scrolling down the margin. On the right side of the screen was a active window titled: BERGEN_TRANS_0730.EXE.
Beside the laptop lay her encrypted drive—the little silver USB drive he had stolen from her desk drawer earlier.
Clara snatched the drive, shoving it deep into her jeans pocket. She looked at the laptop screen. Julian’s system was logged into his master administrator profile, backed up by a hardware key plugged into the side port.
She didn't try to shut down the program; she didn't have time to decrypt his specific protocol. Instead, she inserted her own USB drive into the secondary port, opened his local command prompt, and executed a brute-force memory dump—a simple, crude script she had learned during her firm’s data security seminars.
The laptop screen flashed violently, its fans whirring to maximum speed as it began copying every temporary log, every keystroke, and every encrypted token currently active in Julian’s system memory onto her drive.
TRANSFERRING: 12%... 34%... 68%...
Down below, the basement door slammed open.
"Clara?!" Julian’s voice echoed up the stairwell, sharp, angry, stripped of all its polite, domestic veneer. "What did you do to the thermostat panel?!"
Clara watched the progress bar on the laptop screen.
TRANSFERRING: 89%... 98%... COMPLETE.
She yanked her drive out of the port, snapped the laptop lid shut, and jammed her heavy pry bar directly into the hinge of his expensive laptop display, twisting with all her weight.

The metal groaned, the glass shattered, and the mother-board snapped with a loud, dry pop.
She turned around just as Julian’s heavy footsteps thundered up the basement stairs.
