Model response

Rain polished Blackthorn Manor's windows.
Guests arrived beneath bruised twilight.
Laughter drifted through candlelit halls.
Silver chimed against crystal glasses.
Lady Wren welcomed everyone warmly.
Her smile concealed private worries.
A storm prowled beyond gardens.
Thunder counted seconds between secrets.
Then darkness swallowed every chandelier.
One scream severed pleasant conversation.
When candles flared, Wren lay
motionless beside the grand piano.
Blood threaded through ivory keys.
Nobody moved; everybody breathed guilt.
Inspector Vale removed dripping gloves.
He said, "Lock every door."
