The velvet curtains hung heavy in the silent library while the grandfather clock ticked away the final seconds of life. Lord Blackwood slumped over his mahogany desk with a silver letter opener protruding from the middle of his broad back. A single drop of crimson blood fell onto the white carpet as the heavy oak door creaked slowly wide open. Detective Miller stepped into the room and adjusted his spectacles while ignoring the cold wind blowing through the broken window. He noticed that the expensive vintage brandy had been poured but the crystal glass remained completely full upon the table. Rain lashed against the glass panes as he knelt beside the body to search for any clues the killer left. Suddenly a sharp scream echoed from the hallway outside and shattered the eerie stillness which had permeated this gloomy estate. He grabbed his heavy steel revolver and ran toward the noise knowing that another victim might be facing a killer.
