Dubious character (7)
I believe the answer is:
suspect
This could be a double definition.
'dubious' is the first definition.
(I've seen this before)
'character' is the second definition.
The definition and answer can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?
Can you help me to learn more?
(Other definitions for suspect that I've seen before include "man distrusted?" , "Imagine guilt" , "Funny" , "Dodgy" , "Believe to be guilty, but without proof" .)
