Location of a crime, perhaps, in war (6)
I believe the answer is:
crimea
'war' is the definition.
(I've seen this before)
'location of a crime perhaps' is the wordplay.
'a crime' can be anagrammed to 'CRIMEA'.
But, I'm not sure how the anagram is indicated.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for crimea that I've seen before include "Scene of the charge of the Light Brigade" , "Yalta peninsula" , "Ukraine peninsula, scene of war (1853-6)" , "Ukrainian peninsula, theatre of 1853-6 war" , "1853-56 war zone" .)
