Model response

Candles guttered wildly, throwing nervous shadows across ancestral portraits tonight.
Lady Wren smiled thinly, hiding bruises beneath lace gloves.
The clock struck eight, and somewhere, a woman screamed.
No one moved first; fear pinned everyone inside polished hallways.
Then the lights failed, swallowing whispers, footsteps, and breath.

A silver knife gleamed softly, accusing every trembling face there.
