The cold rain fell against the darkened windows of Blackwood Manor like whispers from the dead who still lingered there. Inside the old library, Eleanor Voss lay completely motionless beneath the grandfather clock, her silver hair pooled with crimson blood. The elderly housekeeper discovered her at midnight, dropping the candlestick when its flickering light revealed the terrible scene before her. Beside the still body rested a shattered pocket watch, its hands frozen precisely at the fateful hour of eleven thirty. Strange fresh scratches marked the locked library door, as though someone had tried desperately to escape their final moments alive. By early morning, Inspector Gray arrived through the fog, carrying a worn leather case and thirty years of quiet suspicion. The assembled household stood trembling in the grand hallway, each guest harboring secrets that would soon unravel like broken thread. Somewhere upstairs, an unfinished letter waited inside a locked drawer, holding the truth that someone was willing to kill for.
