Model response

Fog shrouded the ancient mansion grounds.  
Detective Hale stepped from his car.  
Moonlight revealed the grand oak door.  
He knocked twice, then pushed inside.  
Silence greeted him in the hall.  
A scream shattered the eerie quiet.  
He drew his revolver swiftly now.  
Upstairs, he found the study door.  
Blood pooled on the wooden floor.  
The earl lay dead, eyes wide.  
Poisoned chalice rested on his desk.  
Suspects gathered in the drawing room.  
Who slipped the fatal deadly dose?
