David loved the quiet life he had built for his daughter after years of hard work.
His young daughter Lily was his entire world after her mother passed away three years ago.
He hired Sarah as a live-in nanny to help care for the spacious suburban family house.
Sarah seemed kind and attentive during her first few months of working for the wealthy family.
She always remembered Lily's favorite lunch meals and helped her with school reading assignments every afternoon.
David thought he had finally found someone trustworthy to look after his precious little girl daily.
He spent long hours managing his software company to secure a stable financial future for Lily.
One sunny afternoon David returned home earlier than expected to surprise Lily with a new toy.
He walked through the front door and set his heavy briefcase down on the wooden bench.
The house was unusually silent except for the faint sound of voices coming from upstairs.
David walked toward the stairs while holding the wrapped gift under his left arm tightly.
He suddenly heard Sarah speaking in a sharp and angry tone toward the young girl.
David paused near the bottom of the staircase and listened carefully to the rising argument.
Sarah: Stop crying and put your shoes on right now!
Lily: But my leg hurts from running outside today!
Sarah: I told you to listen to me without complaining every single time!
David felt a cold chill run down his spine as he heard the sudden harshness.
He had never heard Sarah speak so cruelly to his sweet and gentle daughter before.
He moved up the stairs quickly while trying to keep his heavy footsteps completely quiet.
As he reached the top floor balcony he saw Sarah standing over the crying child.
Sarah looked angry as she gripped the young girl's arm with unnecessary physical force.
David gasped aloud as he saw Sarah push Lily backward near the wooden staircase railing.
Lily lost her balance completely and tumbled down the upper steps toward the landing area.
David dropped his briefcase and sprinted across the floor to catch his falling child immediately.
