Harmful look? (4,3)
I believe the answer is:
evil eye
'harmful look?' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for evil eye that I've seen before include "Bad-luck look" , "Malign influence" , "Look supposed to have the power to harm" , "Optical sort of ancient curse" , "Depraved optic with superstitious curse" .)
