The old manor stood silent against the darkening evening sky. Detective Harding’s headlights cut through the thick, driving rain. A single door hung open, spilling light onto wet stones. The grand library was a scene of opulent, violent chaos. Lord Ashworth lay sprawled out upon the priceless Persian rug. A silver letter opener was embedded deep in his chest. His vacant eyes stared up at the high, vaulted ceiling.
