The heavy wooden door suddenly swung open to reveal a pale lifeless body sprawled across the dark marble library floor. Thick crimson blood pooled slowly around his head like a dark halo under the flickering light of the grand chandelier. Detective Arthur Vance stepped carefully into the quiet room while completely avoiding the spreading puddle of wet sticky red blood. A very long sharp silver dagger protruded directly from the chest of the wealthy dead victim beneath his ruined shirt. Vance knelt beside the cold corpse to examine the intricate golden handle gleaming faintly in the very dim overhead light. Someone had clearly and very brutally murdered Lord Ashford in this exact spot without leaving a single visible footprint behind.
