Left late (8)
I believe the answer is:
departed
I believe this clue is a double definition.
'left' is the first definition.
('depart' can be a synonym of 'leave')
'late' is the second definition.
(I've seen this before)
(Other definitions for departed that I've seen before include "Went - dead" , "Quit" , "Dead; set off" , "Left, went away" , "completely breathless" .)
