Ghouls wandering somewhere in Berkshire (6)
I believe the answer is:
slough
'somewhere in berkshire' is the definition.
(town in Berkshire)
'ghouls wandering' is the wordplay.
'wandering' indicates anagramming the letters.
'ghouls' with letters rearranged gives 'SLOUGH'.
(Other definitions for slough that I've seen before include "Swamp; cast off (skin)" , "poet wanted destroyed" , "shed covering" , "A bog or marsh, perhaps of despond" , "Berkshire town and local authority" .)
