No hunter may reveal fugitive (2,3,3)
I believe the answer is:
on the run
'fugitive' is the definition.
(I've seen this before)
'no hunter may' is the wordplay.
'no hunter' can be anagrammed to 'ON THE RUN'.
However, I am unsure how the anagram is indicated.
'reveal' is the link.
Can you help me to learn more?
(Other definitions for on the run that I've seen before include "Fugitive - escaping from arrest" , "Evading capture" , "Trying to avoid capture" , "Marathon contestants are" , "Having escaped custody" .)
