Are not caught? I don’t believe you! (3,4)
I believe the answer is:
get away
'i don't believe you' is the definition.
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for get away that I've seen before include "The car that provides escape for criminal" , "Breakout" , "Escape after crime" , "Escape; short holiday" , "Escape; come off it!" .)
