What the dog does when a spy is discovered? (4)
I believe the answer is:
yaps
'what the dog' is the definition.
I can't judge whether this defines the answer.
'when a spy is discovered?' is the wordplay.
'a spy' can be anagrammed to 'YAPS'.
Though, I am unsure how this is indicated.
'does' acts as a link.
Can you help me to learn more?
(Other definitions for yaps that I've seen before include "Barks" , "Chatters" , "shrill sounds" .)
