The cold rain tapped softly against the dusty study window. Lord Blackwood sat perfectly still in his favorite leather chair. A thin silver dagger protruded sharply from his silk vest. Golden liquid spilled from the broken crystal goblet resting nearby. Arthur gasped loudly, dropping his heavy silver tray of tea. The hot porcelain shattered instantly across the polished hardwood floor. No footprints stained the thick Persian rug near the corpse. The grandfather clock struck midnight with a dull, heavy chime. A single red rose lay abandoned on the cold hearth. The silent killer was already far away in the dark.
