Detective Sarah Chen arrived at Blackwood Manor shortly after midnight, her breath fogging visibly in the cold October night air. Rain hammered against the ancient stone walls while lightning illuminated the twisted wrought iron gates that guarded the manor entrance. Inside the grand foyer, the lifeless body of Lord Edmund Blackwood lay sprawled awkwardly across the polished marble floor tiles. A silver letter opener protruded from his chest, and his sightless eyes stared accusingly up at the portrait above him. The portrait above depicted his late wife, whose mysterious disappearance five years ago had never been solved by police investigators. Six nervous guests remained in the drawing room downstairs, each one silently nursing a drink and avoiding everyone else's eyes. The youngest among them, a pale young woman named Vivian, kept glancing nervously toward the dark staircase beyond the door. The elderly butler claimed he had heard absolutely nothing, though his visibly trembling hands told Chen an entirely different story. Somewhere high above them, a floorboard creaked in the darkness, sending every single guest whirling around toward the unexpected sound. Chen drew her revolver and started slowly toward the stairs, knowing the killer was still hiding somewhere inside this house.
