Mark picked up the metal key from the grass and tucked it safely into his pocket.
He knew he needed real physical evidence before the local police would believe his story.
The mansion had belonged to his family for three generations, holding many ancient secrets.
Mark: I am going down there to see what you have been hiding for years.
Margarethe: If you go down into that room, you will ruin everything we own!
Mark: The law firm and the police are going to search every inch today.
Mark secured the heavy rope around his waist and carefully stepped over the stone edge.
He slowly lowered himself down the dark shaft, his boots scraping against damp moss.
The air grew colder and smelled of damp earth and old forgotten paper as he descended.
He reached the bottom platform and shined his phone flashlight into the dark open room.
The iron trap door led into a small, fully furnished underground concrete vault.
Shelves lined the stone walls, packed with thick legal files and locked metal boxes.
Mark stepped inside the cool space and began scanning the labels on the shelves.
He saw documents carrying his late father's original signature and official seal.
A thick leather binder sat on the central wooden table under a thin layer of dust.
Mark opened the binder and quickly skimmed the legal letters stored inside it.
The paperwork proved that his father had created a irrevocable family trust fund for Mark.
Margarethe had hidden the original will to steal control of the estate and money.
She had been transfering millions of dollars into offshore accounts for several months.
Mark took photos of every single document using the camera on his mobile phone.
He heard a faint rustling noise coming from the top of the deep well shaft.
