Drama created by inspector in new exposure (7,3)
I believe the answer is:
oedipus rex
'drama' is the definition.
(I know that Oedipus Rex genre Greek tragedy)
'inspector in new exposure' is the wordplay.
'inspector' becomes 'di' (abbreviation for Detective Inspector).
'in' indicates putting letters inside.
'new' is an anagram indicator.
'exposure' is an anagram of 'oepusrex'.
'di' going into 'oepusrex' is 'OEDIPUS REX'.
'created by' acts as a link.
(Other definitions for oedipus rex that I've seen before include "Play" , "Drama by Sophocles" , "tragic hero" , "One with complex" .)
