Considered capable of dark deeds? (5)
I believe the answer is:
shady
'considered capable of dark' is the definition.
'shady' can be an answer for 'dark' (thesaurus). I'm not certain of the 'considered capable of' bit.
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for shady that I've seen before include "Of doubtful legality" , "Of questionable morality out of the sunlight" , "Disreputable -- out of the sun" , "Disreputable - umbrageous" , "Suspicious, fishy" .)
