He will be in bad place (4)
I believe the answer is:
hell
'in bad place' is the definition.
'hell' can be an answer for 'place' (I have seen 'Infernal place' mean 'hell' so perhaps 'place' could also mean 'hell'). I'm unsure of the 'in bad' bit.
'he will' is the wordplay.
'will' becomes 'll' (contracted form, as in 'he'll' - 'he will').
'he'+'ll'='HELL'
'be' acts as a link.
Can you help me to learn more?
(Other definitions for hell that I've seen before include "Gehenna" , "Abode of evil spirits" , "uproar" , "Abode of the forces of evil" , "Tartarus, of myth" .)
