Odd post for fictional barrister (7)
I believe the answer is:
rumpole
'fictional barrister' is the definition.
'rumpole' can be an answer for 'barrister' (ref to TV show Rumpole of the Bailey). I'm not sure about the 'fictional' bit.
'odd post' is the wordplay.
'odd' becomes 'rum' (rum can mean strange or dubious).
'post' becomes 'pole' (I've seen this in other clues).
'rum'+'pole'='RUMPOLE'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for rumpole that I've seen before include "John Mortimer's ' - - of the Bailey'" , "Author's brief" .)
