The heavy, cold rain tapped softly against the dusty, cracked window pane of the old, abandoned mansion house nearby tonight. Inside the grand, dark hallway, a terrible scream echoed loudly through every single, dusty corner before falling into silence quickly. Detective Miller arrived late in the cold night wearing his heavy coat while holding a bright flashlight for his guidance. He stepped closer to the body lying on the cold floor with a bloody knife nearby on the ground there. The man who lay dead before him was someone he knew very well from the past many years long ago.
