Covered by Mario Vargas Llosa back in Indian city (4)

I believe the answer is:

agra

I'm a little stuck... Click here to teach me more about this clue!

'indian city' is the definition.
(city in India)

I cannot understand how the rest of the clue works.

(Other definitions for agra that I've seen before include "City in India" , "City famous for its Mogul architecture" , "vicinity of mausoleum" , "Site of the TajMahal" , "city founded in 1566" .)

I've seen this clue in the Irish Times (Crosaire) and The Irish Times.
