Sarah adjusted her plain cotton apron as she walked through the towering glass doors of the Dallas estate.
She had worked as a live-in nanny for the Miller family for nearly two years now.
Her main duty was caring for little baby Lily, who was barely seven months old.
David Miller was a wealthy real estate developer who adored his baby daughter more than anything else.
However, the mood in the grand mansion had changed completely six months ago.
That was when David married Victoria, a bitter woman who loved luxury cars and expensive jewelry.
Victoria never showed any real affection toward little Lily when David was out of the room.
She saw the helpless baby as a rival for David's massive trust fund and family fortune.
Sarah noticed how Victoria constantly complained about the child's presence in the house.
Victoria: Why is that child always crying near my bedroom?
Sarah: She is just hungry, Mrs. Miller.
Victoria: Take her to the north wing immediately.
Sarah held the quiet baby close to her chest, feeling a deep sense of unease.
She knew that Victoria was hiding something terrible behind her polished, cold smile.
David was often away on business trips across Texas, leaving Sarah alone with the stepmother.
Every time David left, Victoria's tone became harsher and more demanding toward the staff.
Sarah kept a detailed diary of every strange incident that occurred inside the home.
She wanted to protect the innocent baby from any potential emotional neglect or harm.
The heavy quiet of the vast marble foyer always made Sarah feel watchful and alert.
She swore to herself that no harm would ever come to the helpless child.
