Turned tail (4)
I believe the answer is:
fled
'turned tail' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for fled that I've seen before include "dashed off elsewhere" , "Having run or hurried away" , "Ran or hurried away" , "Ran off in a hurry" , "Female showed the way and escaped" .)
