Capital in the Andes (4)
I believe the answer is:
lima
'capital in the andes' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for lima that I've seen before include "Mail to Peru's capital" , "Mail it to Peruvian city" , "Mail to capital of Peru" , "city (like 22)" , "distant city" .)
