Peacock's pride (4)
I believe the answer is:
tail
'peacock's pride' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for tail that I've seen before include "Follow furtively like private detective" , "Flexible part that extends from an animal's rear" , "Shadow" , "Follow (a suspect)" , "Dog - or part of one" .)
