Model response

Rain tapped blackened manor windows.
Guests whispered beneath dim chandeliers.
The clock swallowed each heartbeat.
Lady Harrow smiled over supper.
Then someone screamed behind curtains.
Silver clattered across porcelain plates.
Candles shuddered; shadows leapt wildly.
Lord Vale lay motionless, bleeding.
No door had opened anywhere.
Yet muddy footprints crossed marble.
Inspector Wren removed dripping gloves.
He counted faces, finding fear.
One guest quietly hid something.
Outside, thunder erased retreating steps.
Inside, murder took its seat.
