Cornish location where Jerry may hide? (9)
I believe the answer is:
mousehole
I believe this is a double definition.
'cornish location' is the first definition.
(village in Cornwall)
'where jerry may hide?' is the second definition.
(Jerry is a mouse in Tom and Jerry cartoons)
(Other definitions for mousehole that I've seen before include "Little creature's home" , "Murine retreat" , "Opening made by rodent" , "in Cornwall" .)
