The heavy wooden front door creaked open very slowly as the cold midnight wind blew through the dark empty hallway. Detective Miller stepped inside the grand room and immediately noticed a lifeless body lying on the very expensive Persian rug. A single silver dagger was buried deep within the chest of the wealthy victim while fresh red blood pooled around. Three nervous suspects sat quietly in the adjacent library while the lead investigator carefully examined the very bloody murder weapon. Nobody realized that the quiet maid hiding in the dark shadows actually held the missing key to this terrible crime.
