Model response

Rain lashed Blackthorn Hall before dawn.
Servants whispered behind bolted kitchen doors.
A clock coughed midnight's final warning.
Lady Vale descended the staircase slowly.
Her pearls clicked like tiny teeth.
Then someone screamed beneath the library.
Silence followed, thick as velvet.
We found the vicar facedown.
A silver letter opener gleamed.
Blood threaded between Persian carpet flowers.
No window stood open anywhere.
Yet rain pooled around his shoes.
On the mantel, candles shuddered.
Beside them waited one missing glove.
Inspector Crowe arrived without umbrella.
He smiled once, then stopped.
Everyone claimed they heard nothing.
Everyone, except the dead man.
