Mockery made of tryst Eva organised (8)
I believe the answer is:
travesty
'mockery' is the definition.
('travesty' can be a synonym of 'mockery')
'tryst eva organised' is the wordplay.
'organised' is an anagram indicator.
'tryst'+'eva'='trysteva'
'trysteva' is an anagram of 'TRAVESTY'.
'made of' is the link.
(Other definitions for travesty that I've seen before include "Take off" , "Burlesque, mockery" , "Grossly unfair representation" , "Grotesque distortion" , "Mockery, grotesque imitation" .)
