Detective Sarah Chen finally arrived at the crumbling old Victorian mansion just as the heavy gray morning fog slowly lifted. The body of the local tycoon Edmund Blackwood lay sprawled across the grand staircase, his silver hair matted dark crimson. A single brass candlestick rested on the third marble step, still gleaming faintly with evidence of its terrible recent purpose. Behind her, the terrified household staff huddled together in the dimly lit foyer, whispering prayers and avoiding her searching gaze. Sarah knelt beside the cooling body and noticed something strange: his stiff hand clutched a torn piece of yellowed paper. The small paper displayed only five chilling words, written carefully in an elegant feminine hand: "You knew this was coming." Upstairs, somewhere within the shadowed east wing, a single floorboard creaked loudly, and Sarah slowly reached toward her leather holster.
