Model response

Rain silvered Blackthorn Manor's windows.
Inside, twelve guests awaited midnight.
The grandfather clock coughed once.
Then all the candles died.
Someone screamed from the library.
Inspector Vale found Lord Ashford.
He lay beneath shattered glass.
Blood darkened his white waistcoat.
His hand clutched a feather.
No bird lived indoors here.
Every guest denied leaving dinner.
Yet one chair stood empty.
The storm sealed every exit.
Vale smiled, hearing wet footsteps.
