The rain poured down heavily on the old stone mansion as Detective Smith stepped outside quietly without making any noise. He looked at the broken window frame where the missing pearl necklace was found lying on the cold wooden floor. The butler stood silently by the darkened hallway while holding a silver tray with a single cold glass of brandy. A sudden scream echoed through the mansion walls shocking everyone who lived inside the house with pure fear and terror. The heavy wooden door remained locked tight against the unknown threat that waited just outside on the cold dark street.
