Suddenly, a firm young voice called out from the top of the grand marble landing above them.
"Dad, wait! Stop shouting at Sarah right now!" young Lily shouted out as she hurried down.
Lily held her high-definition smartphone high in her hand, displaying a clear video recording playing on loop.
"What are you doing down here, Lily? Get away from this dangerous scene!" Mark said sternly today.
"No, Dad, you need to look at this screen right now before you make a terrible mistake!"
Lily stepped directly between her angry father and the pale, trembling house maid standing in the corner.
She pressed the play button on her smart phone and turned the screen toward Mark's broad face.
"I was filming a dance video for my friends from the upper balcony landing earlier today," Lily said.
"My camera recorded everything that happened near the top of the stairs while you were in office."
Mark looked down at the bright phone screen as the video played back with absolute crystal clarity.
The video clearly showed Victoria standing right next to the stationary baby stroller at the landing.
It showed Victoria looking around slyly before reaching out and unlocking the safety brake with her finger.
The video clearly captured Victoria giving the stroller a firm, deliberate shove down the steep steps.
It also showed Sarah running from the lower hall like a hero to catch the falling baby.
The sound of the video playback filled the quiet hall, exposing the truth to everyone standing there.
Victoria's face turned completely white as all the color drained from her cheeks in an instant.
Mark's jaw dropped open in utter disbelief as he watched the horrifying video clip three times over.
His eyes widened with intense fury as he slowly raised his gaze up toward Victoria's pale face.
"You... you lied to me! You pushed my baby!" Mark said in a low, dangerous tone.
