Land in US city prison the wrong way (5)
I believe the answer is:
nepal
'land' is the definition.
(Nepal is an example)
'us city prison the wrong way' is the wordplay.
'us city' becomes 'la'.
'prison' becomes 'pen' (I've seen this before).
'the wrong way' shows that the letters should be reversed in order.
'la'+'pen'='lapen'
'lapen' backwards is 'NEPAL'.
'in' acts as a link.
(Other definitions for nepal that I've seen before include "Himalayan kingdom" , "Asian kingdom" , "Gurkha homeland" , "Plane country north-east of India" , "somewhere in Asia" .)
