Model response

The stormy night hid every secret.  
Detective Mara found broken glass nearby.  
A distant clock chimed midnight precisely.  
Sirens faded as rain swallowed footprints.  
In the manor, silence felt staged.  
Victim Lionel Black lay motionless, pale.  
Mara examined his hands, trembling slightly.  
The butler claimed innocence, voice steady.  
A lantern flickered, casting shifting shadows.  
On the desk, a sealed letter.  
Its wax bore a crimson sign.
