He's cad to be hunted (6)
I believe the answer is:
chased
'hunted' is the definition.
(I've seen this before)
'he's cad to be' is the wordplay.
'to be' is an anagram indicator.
'hes'+'cad'='hescad'
'hescad' is an anagram of 'CHASED'.
(Other definitions for chased that I've seen before include "Wooed" , "Hunted" , "Pursued at speed" , "Decorated metal with engraved or embossed work" , "Pursued, ran after" .)
