Author, and how she lived ever after, some might say (6,3)
I believe the answer is:
harper lee
'author' is the definition.
'how she lived ever after some might say' is the wordplay.
I cannot quite understand how this works, but
'she' could be 'perle' and 'perle' is found within the answer.
'some' could be 'a' and 'a' is present in the answer.
This may be the basis of clue (or it may be nonsense).
'and' acts as a link.
(Other definitions for harper lee that I've seen before include "Author of Go Set a Watchman, d. 2016 -- paler here (anag)" , "American novelist" .)
