The old manor stood silent beneath a blood red moon while two detectives gathered quietly outside its locked iron gates. Inside the dark library a wealthy host lay strangely dead beside an open window and one shattered crystal wine glass. No one admitted hearing the fatal struggle though every nervous guest had remained inside the house throughout the stormy evening. A single muddy footprint marked the Persian carpet near the cold body and pointed toward the locked garden door beyond. Detective Mara Voss studied each anxious face carefully and soon realized the killer was still standing among them all tonight.
