Maverick fellow, no? (4,4)
I believe the answer is:
lone wolf
'maverick fellow no?' is the definition.
The definition suggests a singular noun which matches the answer.
'maverick fellow no?' is the wordplay.
'maverick' is an anagram indicator.
'fellow'+'no'='fellowno'
'fellowno' anagrammed gives 'LONE-WOLF'.
Can you help me to learn more?
(Other definitions for lone wolf that I've seen before include "One acting singly" , "Solitary operator" , "One avoids the company the others" , "independent type" , "recluse" .)
