Fetched a book by novelist - principally to relax somewhere very remote (3,4,2,6)
I believe the answer is:
the back of beyond
'somewhere very remote' is the definition.
I know nothing about this answer so I cannot judge whether this works.
'fetched a book by novelist principally to relax' is the wordplay.
'principally' says to take the initial letters.
'to relax' is an anagram indicator (I've seen 'relaxing' mean this).
The first letter of 'novelist' is 'n'.
'fetched'+'a'+'book'+'by'+'n'='fetchedabookbyn'
'fetchedabookbyn' with letters rearranged gives 'THE BACK OF BEYOND'.
Can you help me to learn more?
(Other definitions for the back of beyond that I've seen before include "most remote spot?" , "A really remote area" , "Extremely remote place" , "Finding this remote area might need a plan" , "ND" .)
