Deceitful, evasive (6)
I believe the answer is:
shifty
I believe this clue is a double definition.
'deceitful' is the first definition.
(I've seen this in another clue)
'evasive' is the second definition.
(I've seen this in another clue)
(Other definitions for shifty that I've seen before include "Suspicious-looking" , "Evasive, sneaky" , "'Evasive, devious (6)'" , "Sneaky and sly" , "Appearing evasive" .)
