Rain poured heavily onto the cold cobblestones of Blackwood Lane, washing away the fresh blood pooling around the shattered body. Inspector Thomas pulled his damp wool coat tighter as he knelt beside the victim, noticing the strange silver coin nearby. The grandfather clock in the dark manor hall chimed midnight just as the terrified butler pointed toward the open window. A thick velvet ribbon bound the victim's wrists, leaving a deliberate clue that pointed directly toward an old family secret. Nobody inside the locked room was safe anymore, because the clever murderer was undoubtedly still standing among them in silence.
