'type who enters john lewis?' is the definition.
The definition suggests a singular noun which matches the answer.

'fine' is the wordplay.
I cannot quite see how this works, but
'fine' could be 'f' (abbreviation in pencil classifications) and 'f' is located in the answer.
The remaining letters 'logger' 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).
