Idris of "The Wire" (4)
I believe the answer is:
elba
'idris of the wire' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for elba that I've seen before include "Island in the Med" , "Island of Napoleon's first exile" , "Exile isle for Napoleon" , "Island of Napoleon's exile in 1814-15" , "Bale out of the Mediterranean island" .)
