Look this way with suspicion (7)
I believe the answer is:
askance
'look this way with suspicion' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for askance that I've seen before include "(Look) obliquely with mistrust" , "Sideways, awry" , "Look this way in doubt or suspicion" , "With suspicion or disapproval" , "Obliquely, quizzically" .)
