Richard Vance adjusted his dark suit jacket as he walked through the grand entryway of his massive suburban mansion.
The white marble floor reflected the bright afternoon sunlight streaming through the soaring glass windows.
Everything in his life had been carefully ordered since he took over his late father's real estate firm.
Yet a heavy sense of worry had hung over the household for the past three long months.
His sister Clara had vanished without a trace on the very evening she promised to sign her final trust fund documents.
The police had searched every city block, but they found no single clue regarding her sudden disappearance.
Richard spent millions hiring private investigators, yet every lead had ended in a frustrating dead end.
His young daughter Lily trotted quietly across the wide foyer, her pink dress rustling against the smooth polished floor.
She stopped near the base of the grand dual staircase and stared down at the decorative stone tile work.
Richard paused his phone conversation and watched his daughter kneel near the edge of the center marble panel.
Lily: She is down here, Daddy.
Richard frowned slightly and walked over to where his little girl was pointing her small finger.
Richard: What do you mean, sweetie?
Lily: The lady under the floor told me to get you.
Richard felt a cold wave of sudden fear wash down his spine as he looked closely at the marble seam.
He noticed a tiny hidden brass latch tucked neatly into the carved decorative border of the stone floor.
He had lived in this inherited family mansion for five years without ever noticing this concealed square hatch.
Richard motioned for his two personal security guards to step closer to the open space.
Richard: Keep Lily back right now.
He gripped the cold brass latch and pulled upwards with all his strength against the heavy stone door.
The marble hatch creaked loudly as it swung open to reveal a narrow set of brightly lit concrete steps.
A faint voice echoed from the quiet depths below the grand entrance hall.
Richard leaned over the opening, his heart pounding wildly against his ribs as he stared down into the space.
