Left with the threat of evil (8)
I believe the answer is:
sinister
This could be a double definition.
'left' is the first definition.
(I've seen this before)
'threat of evil' is the second definition.
'sinister' can be an answer for 'evil' (I've seen this in another clue). I am not sure about the 'threat of' bit.
'with the' acts as a link.
Can you help me to learn more?
(Other definitions for sinister that I've seen before include "Disquieting" , "Suggestive of evil, being lefthanded" , "Disturbing" , "Suggesting or threatening evil or danger" , "Menacing" .)
