Rain fell heavily upon the cold streets of old London. Inspector Vance stepped carefully across the crime scene blood. Detective Miller held a flashing yellow police warning light high. Someone had murdered the wealthy Duke inside his locked study. Heavy mahogany doors remained completely bolted from the inside. A shattered crystal glass lay beside the velvet armchair. Poison dripped slowly from the silver goblet onto rugs. Vance stared blankly at the pale face of death. No obvious entry points existed within this bizarre room. Tonight would reveal secrets that wealthy men preferred hidden.
