Team of lawyers in literary county (6)
'literary county' is the definition.
(Barset or Barsetshire, county in Trollope novels)
'team of lawyers' is the wordplay.
I cannot really see how this works, but
'team' could be 'set' (I've seen this in other clues) and 'set' is located in the answer.
'lawyers' could be 'bar' (I've seen this before) and 'bar' is found within the answer.
This accounts for all the letters.
This explanation may well be incorrect...
'in' acts as a link.
