I was the daughter who paid the $1,845 mortgage every month, yet my parents told me to become independent while my 35-year-old brother lived rent-free—then, less than 24 hours after I left, I discovered they’d already given away my bedroom while still expecting me to fund their house. / Chapter 72 / 90

Chapter 72 - The Descent into the Abyssal Shaft

The industrial hoist cage hung suspended over an abyss so vast that the high-intensity halogen floodlights could not touch the bottom. Sub-Level 4 was not a basement; it was an abandoned staging terminal, built during the Cold War under the guise of an emergency geological research station. The air here was thin, cool, and carried a rhythmic, vibrating pulse that shuddered through the soles of Cassidy’s boots.

Arthur stood at the auxiliary control platform, his fingers flying across the relay switches. "The main cable is a four-inch braided titanium core," he called out over the rising hum of the winch motors. "The hoist runs on an automated counterweight balance powered by the geothermal siphon Eleanor thought was an irrigation pump. Cassie, once you pass Sub-Level 7, radio communication will be completely blocked by the iron-banded granite formations. You will be on the emergency hardwire intercom only."

Cassidy stepped inside the heavy cylindrical dive capsule, locking the double-sealed bulkhead door behind her. Through the six-inch ballistic glass viewport, she met Arthur’s gaze. "Keep the surface perimeter secure. If Donald’s legal team posts bail, or if Eleanor manages to contact her offshore handlers, shut the primary shaft hatch and flood the lower conduit with industrial foam. Do not let anyone down this tube behind me."

"Understood," Arthur said solemnly. He reached for the pneumatic release lever. "Godspeed, Cassie. Bring him home."

A deafening hiss of compressed air echoed through the staging terminal. The dive capsule lurched, then plummeted into the vertical bore.

The descent was unlike anything Cassidy had ever experienced. There was no sensation of speed other than the rapid fluctuation of the atmospheric barometer mounted beside the viewport. 1,000 feet. 3,000 feet. 8,000 feet. The rock walls outside the reinforced viewport blurred from weathered gray limestone into dense, black volcanic basalt, laced with veins of glittering quartz.

Inside the capsule, the digital console mounted on Cassidy’s chest harness ticked down the remaining reserve time: `OXYGEN COUNTDOWN: 46 HOURS, 12 MINUTES`.

As the depth meter crossed 20,000 feet, the external temperature gauge began to climb. The cooling compressors outside the capsule kicked in with a high-pitched whine, fighting the geothermal heat radiating from the planet's mantle. The Vance family homestead on Ridge Road, with its manicured lawns, wrap-around porch, and peeling paint, was nothing more than a paperweight resting atop a colossal subterranean monument of military engineering.

Cassidy gripped the cylinder tightly. Her mind drifted back to the Thanksgiving dinner that had started this entire crusade. She remembered Donald sitting back in his chair, laughing with grease on his chin, demanding that she pay for the roof repair while Eleanor handed her brother the deed to Cassidy's own hard-earned peace of mind. *“You’re thirty years old, Cassidy. A woman your age should be self-sufficient instead of clinging to this family.”*

The sheer audacity of that statement, delivered while her father was buried alive seven miles below their feet to satisfy Eleanor’s vanity and Donald’s parasitic lifestyle, made Cassidy’s jaw clench until her teeth ached. She was done playing defense. She had taken their deed; she had taken their security; now, she was going to tear out their deepest secret by the roots.

Suddenly, the capsule shuddered violently.

A sharp metallic shriek reverberated through the steel hull. Cassidy grabbed the interior grab-bars as the capsule swung wildly on its guides. The depth gauge halted abruptly at 36,800 feet.

The console flared yellow: `SYSTEM INTERRUPT: SHAFT OBSTRUCTION AT TRANSIT JUNCTION 9. HOIST MOTOR AUTO-BRAKE ENGAGED.`

Cassidy hit the hardwire intercom button. "Arthur! I’ve stopped short of the trench floor. The guides are jammed. What’s happening on the surface?"

Only heavy, static-laced breathing responded. Then, a distorted voice crackled through the analog line, but it was not Arthur’s calm cadence.

"You really should have left the keys on the kitchen counter, little sister."
