Amanda stood at the threshold of the long entrance hall, her knuckles whitening as she gripped the dark oak banister.
Amanda: Jason, did you hear that knocking coming from underneath the floorboards?
Jason: There is nothing down there, Amanda. It is just an old heating pipe rattling against the boiler.
Amanda: That was not a pipe. It sounded like someone tapping three distinct times with a piece of metal.
Jason: You have barely slept four hours since your flight landed from New York. We should head back upstairs to the study before Claire returns from the funeral director's office.
Amanda: Claire told every shareholder at the probate hearing that my mother checked herself into a private clinic in Arizona three weeks ago.
Jason: She presented a notarized medical statement to the probate court, Amanda. She has full executor authority over your late father's family business and the entire trust fund.
Amanda: My mother would never abandon Lily. She would never walk away without leaving a note, let alone sign away her primary marital rights to a stepmother who showed up eighteen months ago.
Amanda took three quiet steps down the cellar staircase, her flat shoes making no sound against the worn wooden steps.
Jason: Please, Amanda. If the estate security guard sees us snooping down here, Claire will file an emergency injunction to freeze your inheritance shares.
Amanda: Let her try. This house belongs to my parents' joint trust. I am checking the old fruit storage room right now.
She reached the cold concrete landing and aimed the flashlight from her phone toward the dark alcove behind the furnace.
A heavy steel chain was looped through the double handles of the reinforced storm door, sealed tight with a gleaming brass padlock.
Amanda: Look at this, Jason. Claire told the home appraiser that this room was sealed off because of toxic black mold.
Jason: That is a commercial Grade-5 hardened padlock. You don't put hardware like that on a moldy fruit pantry.
A soft rustling sound came from beneath the door, followed by a pale, trembling piece of lined paper sliding through the crack at the base.
Amanda dropped to her knees on the cold concrete, snatching the paper and unfolding it beneath the bright white light.
Written in faded blue ink was her mother's unmistakable, delicate handwriting: "Amanda, do not let Claire sign the corporate transfer. She locked me inside. Help me before the hearing tomorrow."
Amanda felt the air vanish from her lungs as a muffled, desperate sob echoed from the other side of the heavy wood.
