Hide in cubbyhole at hermitage (7)
I believe the answer is:
leather
'hide' is the definition.
(an animal hide)
'in cubbyhole at hermitage' is the wordplay.
'in' indicates a hidden word.
'LEATHER' is hidden in the letters of 'cubbyhole at hermitage'.
(Other definitions for leather that I've seen before include "kid, say" , "Morocco, perhaps" , "Fabric" , "Flog; hide" , "Tanned animal skin" .)
