The fog rolled thick across Blackwood Manor's imposing stone facade. Detective Sarah Chen stepped from her car into darkness. The butler's trembling hands guided her through ornate wooden doors. Inside, crystal chandeliers cast eerie shadows on marble floor below. Lady Margaret Blackwood lay motionless beside the grand piano tonight. Blood pooled beneath her silver hair in crimson streams. The murder weapon, a brass candlestick, glinted near her. Her emerald necklace was missing from around her neck. Six dinner guests stood frozen in the luxurious drawing room. Each face revealed secrets hidden behind masks of shocked innocence.
