'spanish city' is the definition.
I know nothing about this answer so I can't tell whether this works.

'half-forgotten homicide spooks' is the wordplay.
'half forgotten' indicates taking half.
'homicide' becomes 'murder' (synonyms).
'spooks' becomes 'CIA' (spooks can mean spies).
'murder' cut in half is 'mur'.
'mur'+'cia'='MURCIA'
