Writer honest about better books on race (6,6)
I believe the answer is:
truman capote
'writer honest' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.
'better books on race' is the wordplay.
I cannot quite see how this works, but
'better' could be 'cap' (both can mean to beat somebody else's attempt) and 'cap' is found within the answer.
'books' could be 'ot' (Old Testament) and 'ot' is present in the answer.
'race' could be 'man' (the human race) and 'man' is located in the answer.
The remaining letters 'true' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'about' is the link.
Can you help me to learn more?
(Other definitions for truman capote that I've seen before include "US author supplied" , "Author of Breakfast at Tiffany's" .)
