Detective Miller entered the conservatory at precisely midnight last night. Rain hammered the glass ceiling above the motionless elegant woman. Her gloved hand still tightly clutched a shattered crystal goblet. No footprints marked the wet soil completely surrounding her body. The butler watched silently from the shadowed doorway without breathing. Miller noticed his polished shoes were perfectly dry despite storm. Someone had killed her without ever entering this locked room.
