Rain whispered against Blackthorn Manor as mourners gathered beneath thunder. Candles trembled wildly, throwing long shadows across ancestral portraits tonight. Lady Vale descended slowly, her veil hiding grief and calculation. At midnight, the clock chimed thirteen, then someone screamed upstairs. We found Sir Alistair sprawled beside shattered glass and roses. His ringless hand pointed toward the locked study door accusingly. No window stood open, yet mud stained the Persian carpet. Among the guests, one face remained dry despite stormy weather. Inspector Wren removed his hat and surveyed our frightened silence. Then he announced, “The killer is here, listening carefully now.”
