Handsome guy wrong to return after commotion (6)
I believe the answer is:
adonis
'handsome guy' is the definition.
(I've seen this in another clue)
'wrong to return after commotion' is the wordplay.
'wrong' becomes 'sin' (wrong can mean a sin or crime).
'to return' says the letters should be written backwards.
'after' says to put letters next to each other.
'commotion' becomes 'ado' (ado is a kind of commotion).
'sin' reversed gives 'nis'.
'nis' after 'ado' is 'ADONIS'.
(Other definitions for adonis that I've seen before include "Beautiful (Greek) man" , "Said no to the Greek youth" , "Beautiful Greek youth" , "Hunk" , "Handsome youth - boy from Greek mythology" .)
