Mark walked into the bright living room of the grand estate with a heavy feeling in his heart.
He had lived in this huge mansion for only three years after marrying into a wealthy family.
His wife, Sarah, always wore expensive blue silk shirts and lived a life of total luxury.
Mark cared deeply for his little daughter, Lily, who had lost her biological mother when she was just a baby.
The mansion was filled with white marble floors and polished stairs that echoed with every single step.
Mark spent most of his days managing his late father-in-law's legal estate and checking sensitive documents.
He wanted to ensure that Lily would have a secure future and a safe inheritance when she grew up.
Sarah had always been quiet and somewhat distant toward the young girl.
Mark hoped that time would heal the gap between his new wife and his young daughter.
He noticed that Sarah kept certain locked boxes inside her private upstairs study.
Whenever Mark asked about those documents, Sarah quickly changed the whole topic.
She said those files were just old tax papers from her family business.
Mark did not want to push his wife into an uncomfortable argument.
He trusted her completely because he believed in keeping his new family peaceful and happy.
One afternoon, Mark returned home early from his law office downtown.
The house was unusually quiet as he entered the heavy double doors.
He called out for his daughter, but no one answered from the kitchen.
A sudden chill went down his spine as he heard faint noises coming from upstairs.
He walked slowly toward the grand marble staircase to investigate the sound.
He had no idea that a dark secret was about to surface today.
His life was about to change in a single terrifying moment.
