Bit of scandal, ostensibly misplaced (4)
I believe the answer is:
lost
'misplaced' is the definition.
('lose' can be a synonym of 'misplace')
'bit of scandal ostensibly' is the wordplay.
'bit of' indicates the answer is hidden within the clue.
'LOST' is hidden in the letters of 'scandal ostensibly'.
(Other definitions for lost that I've seen before include "Mislaid or irretrievable" , "See 10" , "Unable to find the way forward" , "Suffered defeat" , "Forgotten; misplaced" .)
