Rendering of a perfect theme in pastoral scene (4,9)
I believe the answer is:
fete champetre
'pastoral scene' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'rendering of a perfect theme' is the wordplay.
'a perfect theme' anagrams to 'FETE CHAMPETRE'.
But, I'm not sure how the anagram is indicated.
'in' is the link.
Can you help me to learn more?
(Other definitions for fete champetre that I've seen before include "Garden party" , "Outdoor entertainment" .)
