Thus a cheat sucked in film hub, eventually? (6,2,5)
I believe the answer is:
sooner or later
'eventually?' is the definition.
('sooner or later' can be a synonym of 'eventually')
'thus a cheat sucked in film hub' is the wordplay.
I cannot really see how this works, but
'thus' could be 'so' (synonyms) and 'so' is found within the answer.
'a' could be 'one' and 'one' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for sooner or later that I've seen before include "not on the dot" , "Inevitably" , "At some point" , "offering alternative times" , "Errors (a lot) one corrected, eventually" .)
