Fog draped the town, muffling whispers of impending dread night. Detective Mara arrived, her coat soaked in relentless rain today. She entered the manor, noticing candles flickering like nervous eyes. The butler whispered, “Lord Hargrove lies still, blood staining silk.” Mara knelt, observing a single rose placed beside corpse cold. A hidden diary fluttered, promising secrets that would shatter peace.
