Model response

The detective arrived at the old mansion under a stormy sky filled with ominous dark clouds.  
A single scream had echoed through the silent night alerting all the worried neighbors nearby.  
Blood stained the antique carpet in the study where the victim lay motionless and cold.  
Everyone gathered in the hallway whispering accusations while hiding their own terrible secrets carefully.  
The clock struck midnight exactly as the inspector began examining the mysterious fatal wound closely.
