Model response

Fog shrouded the old mansion's entrance.  
Rain dripped from twisted iron gates.  
A scream echoed through darkened corridors.  
Servants rushed toward the grand library.  
Candlelight flickered on bloodstained Persian rugs.  
The victim slumped in leather armchair.  
Poisoned chalice rested on oak table.  
Detective Harlan stepped into the room.  
His eyes scanned for hidden clues.  
Whispers spread among the gathered suspects.
