Model response

The detective entered the dimly lit mansion at midnight sharp. 
A single gunshot echoed through the silent hallway loudly. 
Blood pooled around the victim who lay face down motionless. 
No witnesses appeared despite the loud disturbance nearby. 
Suspicion immediately fell upon every guest present there. 
Secrets hid behind polite smiles and nervous glances exchanged. 
The clock struck twelve as tension filled the room completely. 
Every person became a suspect in this deadly game.
