... dine out with Miss Blyton? (4)
I believe the answer is:
enid
'miss blyton?' is the definition.
(I've seen this before)
'dine out' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'dine' is an anagram of 'ENID'.
'with' is the link.
(Other definitions for enid that I've seen before include "- Blyton, twentith century writer" , "Miss Blyton" , "'... Blyton, children's author (4)'" , "Geraint's wife's" , "Woman" .)
