The cold rain hammered relentlessly against the tall windows of Blackwood Manor, blurring the lightning flickering across the dark countryside. Detective Sarah Chen stepped slowly out of her car and stared up at the imposing old house looming before her. A pale butler waited nervously at the front door, his trembling hands betraying the fear that he could barely hide. He led her silently through the grand hallway, past portraits of stern ancestors, toward the library where cold death waited. Lord Ashworth lay slumped across his writing desk, a silver letter opener protruding from his pale back with terrible finality. Sarah circled the body slowly, noting the overturned inkwell, the scattered papers, and the complete absence of any forced entry. On the desk, hidden beneath a leather folio, lay a torn photograph of a young woman she did not recognize. Someone in this old house was lying, and Sarah knew the truth would surface before the final storm passed through.
