Cold rain tapped relentlessly against the dark stained glass windows. Detective Miller adjusted his wet trench coat by the door. Lord Blackwood lay motionless upon the expensive Persian rug inside. A silver dagger protruded from his tailored silk evening jacket. Crimson blood pooled slowly around the shattered crystal brandy glass. The grandfather clock had stopped at precisely midnight that evening. Nobody in the sprawling mansion claimed to hear any struggle. Yet muddy footprints led directly toward the locked library balcony. Miller knew the clever killer remained hidden inside this house. He opened his small leather notebook and began the investigation.
