Cold rain tapped against the glass windows of the manor. Lord Blackwood lay dead upon the expensive Persian wool rug. A sharp silver dagger was buried deep within his chest. Inspector Miller stood over the corpse with a grim expression. The antique clock on the mantel struck midnight with authority. A spilled glass of red wine pooled near his hand. The frightened butler trembled while holding a tray of tea. The killer is still somewhere inside this house right now.
