Model response

The heavy storm battered the isolated mansion on that fateful winter night.
Elegant guests gathered in the parlor for the lavish dinner party.
Laughter filled the air as stories flowed amid clinking wine glasses.
Suddenly a maid's bloodcurdling scream shattered the evening's warm conversation abruptly.
Guests raced up creaking stairs toward the source of terror now.
In the library they discovered the host sprawled lifeless on floor.
Blood pooled around his head from a fatal blow delivered.
The detective arrived at dawn to unravel the killer's hidden motive.
