Mediterranean islander in prison with army officer (8)
I believe the answer is:
majorcan
'mediterranean islander' is the definition.
'majorcan' can be an answer for 'islander' (I've seen this before). I'm not certain of the 'mediterranean' bit.
'prison with army officer' is the wordplay.
'prison' becomes 'can' (the can is American slang for prison).
'with' is a charade indicator (letters next to each other).
'army officer' becomes 'major' (I've seen this before).
'can' put after 'major' is 'MAJORCAN'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for majorcan that I've seen before include "Man from Palma" , "islander" .)
