More dead in the future? (5)
I believe the answer is:
later
I believe this clue is a double definition.
'more dead' is the first definition.
('late' can be similar in meaning to 'dead')
'in the future?' is the second definition.
(I've seen this before)
(Other definitions for later that I've seen before include "At some time afterwards" , "After a given point in time" , "behind schedule" , "at a subsequent point" , "at a future date" .)
