The Stranger in the Field

What is Hazel missing about his old warren?
he is missing the familiar tunnels and the smell of rabbit.

Who is the stranger in the field? 
 His name is Cowslip. ??????

How do Hazel & the others feel about him?
They feel confused. Is he telling the truth? Or is 
he lying to them?

What do you guess will happen next?
Maybe they will leave and find a different spot.
or maybe they will stay. I think if they stay 
they will be in big trouble.
