Heavy rain lashed violently against the dark, frozen glass window. Detective Miller stepped slowly into the quiet, bloodstained library room. Lord Harrington slumped forward across his massive mahogany writing desk. A silver letter opener was buried deeply within his chest. Crimson blood dripped silently onto an unfinished, handwritten confession letter. The heavy grandfather clock suddenly struck midnight in the silence. Cold footsteps echoed very softly down the long, dark hallway. The clever murderer was clearly still hiding inside this house.
