Mark looked intently at the baseboard where Lily had placed the white porcelain plate of food.
At first glance, the bright white trim looked just like every other decorative wall panel inside the luxury mansion.
However, when Mark leaned closer, he noticed a hairline crack running vertically through the solid painted wood.
His breath hitched in his chest as he realized the seam was not a natural flaw in the drywall.
It was a concealed door handle mechanism built directly into the custom carpentry of the hallway.
Sarah: Mark, you are home early today.
Mark turned his head quickly to see his wife, Sarah, standing at the top of the short hallway steps.
She wore an elegant cream silk blouse paired with a dark brown tailored pencil skirt.
Her face went completely pale as her eyes landed on Mark kneeling right beside the open wall seam.
Mark: Sarah, what is this seam doing here in the hallway baseboard?
Sarah clutched her gold necklace tightly as her posture stiffened up instantly in the bright light.
Sarah: That is just an old access hatch for the main plumbing lines, Mark.
Mark: Why is Lily putting fresh food down right next to an access hatch?
Sarah took a hesitant step down the stairs, her eyes darting nervously toward the front entry door.
Sarah: She is just playing pretend, like toddlers always do when they are bored.
Mark reached out his right hand and touched the cold wooden edge of the hidden panel seam.
A soft creaking sound echoed through the hallway as the hidden wall panel cracked open a tiny fraction.
Mark felt his heart pounding violently against his ribs as a strange smell drifted out from the opening.
It was the scent of old wool blankets, stale bread crumbs, and cool trapped air.
Mark: This is not an access hatch for plumbing lines, Sarah.
Sarah: Please, Mark, just leave it alone and come into the kitchen with me right now.
Mark ignored his wife's pleading voice and hooked his fingers firmly into the narrow wooden gap.
He pulled backward with all his strength, forcing the hidden door panel to slide open completely.
