The heavy rain hammered against the tall windows of Blackwood Manor, drowning out the screams that nobody heard that night. By morning, the terrible storm had passed, leaving behind a silence that felt heavier than the clouds it replaced entirely. Detective Sarah Chen arrived at seven sharp, her boots crunching on the gravel path that led toward the front door. Inside the study, Reginald Blackwood sat slumped in his leather chair, a silver letter opener buried deep in his chest. His cold fingers clutched an unsent letter, its ink smudged where a single drop of blood had fallen upon it. Sarah studied the room carefully, noting the absent dust circles where paintings once hung and the safe standing strangely open. Six guests had stayed the night, and every single one of them had a good reason to want him dead. The housekeeper claimed she heard nothing, though her trembling hands suggested otherwise as she poured tea into delicate porcelain cups. Outside, the nervous gardener was digging a fresh hole, and Sarah could not help but wonder what he was burying. The storm had erased all footprints from the garden, but secrets have a way of surfacing no matter the weather. Sarah pulled out her worn notebook and wrote a single question at the top of the first clean page available. Who among these six strangers had hated Reginald Blackwood enough to drive silver into his heart on that stormy night?
