Pretend one's not interested in baffling drama? (4,4,2,3)
I believe the answer is:
play hard to get
I believe this clue is a double definition.
'pretend one's not interested' is the first definition.
(to play hard to get is to feign a lack of interest)
'baffling drama?' is the second definition.
(I've seen this before)
'in' acts as a link.
(Other definitions for play hard to get that I've seen before include "Gain by appearing unwilling to co-operate" , "Feign unwillingness as negotiating ploy" , "Make a show of unwillingness" , "abstruse bit of theatre?" , "Pretend unwillingness to gain advantage" .)
