Killer stalks Frenchman in Spanish location (7)
I believe the answer is:
minorca
'spanish location' is the definition.
The definition suggests a singular noun which matches the answer.
'killer stalks frenchman in' is the wordplay.
'killer' becomes 'orc' (I've seen this before).
'stalks frenchman' becomes 'mina' (I am not sure about this - if you are sure you should believe this answer much more).
'in' means one lot of letters goes inside another.
'orc' put inside 'mina' is 'MINORCA'.
Can you help me to learn more?
(Other definitions for minorca that I've seen before include "One of Balearic islands" , "holiday island" , "Balearic island; O, cram in (anag.)" , "Mediterranean island" , "Balearic island (Eng. sp.)" .)
