Gets wind of (5)
I believe the answer is:
'gets wind of' is the definition.
('hear' can be a synonym of 'get wind of')
This is all the clue.
(Other definitions for hears that I've seen before include "Share (anag.)" , "Tries judicially" , "Listens and pays attention" , "Perceives sound" , "Finds out; tries" .)
