Mark pulled his expensive black sedan into the long driveway of his Dallas estate.
The sun was beaming brightly over the manicured lawn and green hedges.
He had just finished a high-stakes meeting down in Austin three hours ahead of schedule.
He wanted to surprise his wife, Sarah, and their six-year-old daughter, Lily.
Mark stepped out of the vehicle and grabbed his leather briefcase from the passenger seat.
He walked up the front steps of the massive white mansion.
The front door was slightly ajar, which immediately caught his attention.
Mark knew his wife was always careful about security in their gated community.
He pushed the heavy wooden door open and stepped into the grand entryway.
The high-key bright lighting illuminated the pristine white marble floors.
Above him, the massive crystal chandelier cast soft reflections across the high ceiling.
The house was completely silent, except for a faint sound coming from the main hall.
Mark set his briefcase down near the side table near the entryway.
He listened closely and recognized the soft sound of a child crying.
"Lily?" Mark called out gently into the quiet hall.
He walked toward the base of the grand curved staircase.
Standing near the edge of a thick Persian rug was his little girl, Lily.
She was wearing her favorite pink dress, but her cheeks were stained with fresh tears.
Mark dropped to his knees immediately to meet her at eye level.
He reached out and took her small, trembling hands into his own.
"Sweetheart, what happened?" Mark asked, his voice filled with worry.
Lily wiped her nose with the back of her hand and sniffled softly.
She didn't speak right away, but her chest rose and fell with quick breaths.
Mark looked around the empty entryway, expecting his wife to appear from the kitchen.
"Where is your mother? Is Sarah upstairs?" Mark asked softly.
Lily shook her head side to side very slowly.
She raised her right hand and pointed a trembling finger toward the floor.
Specifically, she was pointing at a hidden seam tucked beneath the corner of the rug.
Mark frowned as he realized the rug had been pulled back several inches.
Beneath it lay an iron handle attached to a wooden trapdoor in the marble.
He had owned this mansion for four years and had never noticed this hatch.
Lily looked directly into her father's eyes with pure fear.
"Mommy's in there," Lily whispered in a tearful voice.
Mark felt a cold chill run down his spine as he stared at the trapdoor.
