Nothing left, okay? (3,5)
I believe the answer is:
all right
I believe this clue is a double definition.
'nothing left' is the first definition.
(I've seen this before)
'okay?' is the second definition.
('all right' can be a synonym of 'okay')
(Other definitions for all right that I've seen before include "Unhurt - very good" , "Very well, everything's ok" , "Safe - adequate" , "Nothing left" , "Safe - acceptable" .)
