Not straightforward (7)
I believe the answer is:
evasive
'not straightforward' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for evasive that I've seen before include "Prevaricatory" , "make out-of-the-way sort of action" , "Quibbling" , "Avoiding commitment" , "Shifty; equivocating" .)
