Model response

The old clock struck midnight eerily. 
A single scream pierced silence suddenly. 
Blood pooled across wooden floorboards silently. 
Detective arrived with notebook ready. 
Shadows danced upon pale walls ominously. 
The victim clutched one final clue. 
Rain hammered against darkened windows relentlessly. 
Everyone present seemed suspiciously nervous now.
