Opera set in Ascot? (5)
I believe the answer is:
tosca
'opera' is the definition.
(I've seen this before)
'ascot?' is the wordplay.
'ascot' anagrams to 'TOSCA'.
Though, I'm not clear how the anagram is indicated.
'set in' acts as a link.
Can you help me to learn more?
(Other definitions for tosca that I've seen before include "opera singer" , "musical work" , "Opera at Ascot?" , "Luigi -, Italian playwright" , "Opera - a Scot (anag)" .)
