Sarah kept her footsteps entirely silent as she approached the bottom of the grand grand spiral staircase.
The sharp sound of Elena's harsh voice echoed loudly down the empty marble hallway above her head.
Elena: Stop crying right now, you noisy brat, before you ruin my expensive new dress!
Sarah paused near a large indoor house plant to observe the shocking scene playing out upstairs.
Elena was holding little Leo roughly by his small arm while pulling him toward the back hallway.
The poor baby was crying bitterly while reaching his small hands out for help in complete distress.
Elena showed absolutely no comfort or warmth toward the terrified nine-month-old child in her hands.
Instead, she placed the crying infant directly on the cold marble floor near the open balcony edge.
She walked away toward her dressing room, leaving the vulnerable baby completely unsupervised near dangerous stairs.
Sarah felt her heart pounding wildly against her chest as anger rushed through her entire body.
She quickly reached into her dark uniform pocket and pulled out her small personal smartphone.
Sarah knew that simple words would never be enough to convince Arthur about his wife's cruelty.
She needed clear and indisputable visual proof that nobody could ever deny or try to explain away.
Sarah pressed the record button on her screen while holding the camera steady through the railing gaps.
The phone clearly captured Elena returning and yelling harshly at the helpless crying baby on the floor.
Elena: I never wanted to be a nanny to a brat when I married into this wealthy family!
The recording captured every single cruel word and heartless action in crystal clear high-definition detail.
Sarah pulled her phone back slowly after recording two whole minutes of continuous undeniable evidence.
She stepped out from behind the grand pillar and walked briskly up the wide carpeted staircase.
Sarah: Stop right there, Elena! Step completely away from that baby this instant!
Elena turned around instantly, her face turning pale with absolute surprise and sudden furious panic.
Elena: How dare you speak to me like that in my own private mansion, you servant!
Sarah: You are neglecting this innocent child, and I am putting a complete end to it today!
Sarah rushed forward and gently scooped little Leo safely into her protective arms away from Elena.
The baby held onto Sarah's uniform collar, gasping for air while slowly settling down from his tears.
Elena: Hand him back to me right now or I will have you thrown out on the street!
Sarah: You will never harm or neglect this precious boy ever again while I am standing here!
