Du Maurier novel not popular around Caribbean nation (8)
I believe the answer is:
jamaican
'caribbean nation' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'du maurier novel not popular around' is the wordplay.
I cannot quite understand how this works, but
'around' could be 'ca' (circa) and 'ca' is located in the answer.
'popular' could be 'in' and 'in' is located in the remaining letters.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for jamaican that I've seen before include "Bob Marley, for instance" , "Islander" , "Caribbean inhabitant" , "From Kingston, perhaps" , "One type of West Indian" .)
