All I ask in return is containing trouble (3)
I believe the answer is:
ail
'trouble' is the definition.
(I know that trouble can be written as ail)
'all i ask in return is containing' is the wordplay.
'is containing' indicates the answer is hidden within the clue.
'in return' says the letters should be written backwards (return can mean to go backwards).
'lia' is hidden in the letters of 'all i ask'.
'lia' written backwards gives 'AIL'.
(Other definitions for ail that I've seen before include "Be unwell, feel poorly" , "Be the worse for wear" , "Afflict; suffer" , "Be unwell, suffer" , "Become unwell" .)
