County in which kippers can be found? (4)
I believe the answer is:
beds
I believe this clue is a double definition.
'county' is the first definition.
(abbreviation for Bedfordshire)
'in which kippers can be found?' is the second definition.
(people kipping or sleeping in bed)
(Other definitions for beds that I've seen before include "Graduate teacher's" , "Place" , "Dormitory items" , "to which people may retire" , "area that includes Luton" .)
