Thick fog crept across the black iron gates of Blackwood Manor while rain battered the antique stained glass library windows. Inside the study, Lord Harrington slumped silently over his mahogany desk, a silver dagger buried deeply between his frail shoulders. Fresh crimson blood slowly pooled beneath his unfinished will, staining the expensive parchment and dripping steadily onto the Persian rug. Detective Miller paused in the shadowed doorway, adjusted his wet coat, and noticed the antique pocket watch stopped at midnight.
