The heavy velvet curtains blocked every trace of the moon. A single silver letter opener lay deep inside his chest. Dark blood dripped slowly onto the expensive Persian rug below. Nobody heard the muffled scream behind the heavy oak door. The grandfather clock chimed once to mark the midnight hour. One pale hand clutched a crumpled note inside his pocket. Cold rain started tapping against the glass of the window. A faint smell of expensive cigar smoke filled the air. The killer vanished into the shadows without leaving one footprint. Only the dead man knew the secret of the vault.
