The rain hammered against the windows of Blackwood Manor that evening. Inspector Sarah Chen arrived just past midnight, her coat soaked completely. Inside, the foyer smelled of lavender, old wood, and something metallic. Butler Thomas Grayson stood pale and trembling near the grand staircase. He had found the body at exactly eleven forty-five tonight. Upstairs, in the study, Lord Edmund Blackwood lay quite still. A silver letter opener protruded from his chest with cruel precision. His glass of brandy sat untouched on the polished mahogany desk. Papers scattered everywhere suggested a struggle had taken place here earlier. Chen noticed the fireplace held ashes of something recently burned completely. Someone had wanted very much to destroy the evidence tonight. She pulled on her gloves and began her careful methodical work. Outside, thunder rolled across the estate like distant ominous applause.
