Model response

Rain slicked the manor steps as midnight tolled twice below.
Inside, portraits watched silently while thunder worried the ancient windows.
Lord Haversham greeted guests warmly, though his smile seemed borrowed.
Candles trembled along corridors smelling faintly of roses and gunpowder.
At dinner, conversation glittered brittle as crystal beneath chandeliers above.
Then lights failed suddenly, swallowing silverware, secrets, and someone's breath.
A scream rose sharply; when brightness returned, Haversham lay dead.
Beside his chair rested a teacup, steaming, untouched, accusing everyone.
