Reveals how to struggle free from frenzied wolfhounds (7)
I believe the answer is:
unfolds
'reveals' is the definition.
(unfolding is a kind of revealing)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for unfolds that I've seen before include "Gradually reveals" , "Opens, spreads out" , "(Of a story) develops" .)
