Thunder rattled the frosted windowpanes of Blackwood Manor while icy autumn rain lashed relentlessly against the ancient stone facade outside. Detective Miller shook the moisture from his heavy trench coat before stepping cautiously into the dimly lit private library tonight. Lord Harrington slumped motionless across his massive mahogany desk with a silver letter opener buried deep inside his arched back. Fresh crimson blood dripped steadily onto a torn parchment letter containing an urgent warning about an impending dark family betrayal. The grandfather clock struck midnight as Miller noticed the locked iron door and realized that the killer never actually escaped.
