Return of actor in epic, or performing ... (13)


I believe the answer is:

'return' is the definition.
(reciprocation is a kind of return)

'actor in epic or performing' is the wordplay.
'performing' indicates an anagram.
'actorinepicor' with letters rearranged gives 'RECIPROCATION'.

'of' is the link.

(Other definitions for reciprocation that I've seen before include "Mutual giving and receiving - cop in race riot (anag)", "returning the same gestures?", "Giving, in return".)

I've seen this clue in The Telegraph.
