The heavy velvet curtains blocked the pale moonlight from entering the cold room where the dead man now lay. A single crystal glass sat on the mahogany table beside a small pile of white powder and one gold coin. Inspector Reed stepped over the threshold while his boots clicked loudly against the polished marble of the grand entry hall. He noticed that the victim wore a silk robe that was stained with a dark liquid near the pale neck. The wind howled outside the tall windows as the clock struck midnight with a slow and very haunting metallic chime. Someone had locked the heavy oak door from the inside, leaving no clear path for a killer to escape. Reed leaned closer to the body to see if the strange scent of bitter almonds lingered in the still air. He knew that the secret to this crime rested within the leather journal clutched tightly in the dead man's hand.
