"Iliad” setting (4)
I believe the answer is:
troy
'iliad setting' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for troy that I've seen before include "City impacted by long-term investment" , "Ancient city associated with a wooden horse" , "Ancient city, Ilium" , "System of weights introduced by French" , "Hardy sergeant" .)
