Shelter in Middle England (3)
I believe the answer is:
lee
'shelter' is the definition.
(as in lee side, the side sheltered from wind)
'in middle england' is the wordplay.
'in' indicates a hidden word.
'LEE' is hidden in the letters of 'middle england'.
(Other definitions for lee that I've seen before include "Protection" , "Commander of the Confederate States Army in the American Civil War" , "Cork river" , "Towards the side away from the wind (naut)" , "The sheltered side - of Cork's river?" .)
