Malevolent look (4,3)
I believe the answer is:
evil eye
'malevolent look' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for evil eye that I've seen before include "Look supposed to have the power to harm" , "Supposedly harmful glance" , "Look that inflicts harm" , "Look that can be harmful?" , "Supposedly harmful stare" .)
