# The Silent Study

Rain hammered against the window. 
Detective Sarah Cole checked her watch. 
The body lay near the fireplace. 
Blood pooled beneath the victim's head. 
Nobody heard the fatal gunshot. 
The study door remained locked tight. 
Six guests waited in the hallway. 
Each one claimed complete innocence now. 
The old clock struck midnight loudly. 
Cole knelt beside the cold corpse. 
His wallet sat untouched on desk. 
This wasn't a simple robbery then. 
Someone in this house knew truth. 
She glanced toward the nervous butler. 
His hands trembled around a tray. 
Secrets filled every corner of Ashford. 
Tonight, those secrets would finally surface.
