Went to bed, having stopped work (7)
I believe the answer is:
retired
This clue is a double definition.
'went to bed' is the first definition.
('retire' can be a synonym of 'go to bed')
'having stopped work' is the second definition.
(I've seen this before)
(Other definitions for retired that I've seen before include "went back" , "Left" , "out of office?" , "Turned in" , "Gone to bed" .)
