Model response

Rain hammered the manor windows.
Detective Mara Voss arrived late.
Her coat dripped onto marble.
The butler met her silently.
Ashworth waits upstairs, he whispered.
Mara climbed the staircase slowly.
Each step creaked beneath her.
The study door stood ajar.
Inside, a single candle flickered.
Ashworth slumped motionless across desk.
A silver letter opener protruded.
Mara noticed the second glass.
Its wine still glistened darkly.
Someone had been here recently.
Thunder rolled across the estate.
Then every light suddenly died.
Darkness swallowed the room whole.
Behind her, someone exhaled softly.
