Get Naomi to leave mediation or change one's story? (4)
I believe the answer is:
edit
'change one's story?' is the definition.
'edit' can be an answer for 'change' (editing is a kind of changing). I am unsure of the 'one's story?' bit.
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for edit that I've seen before include "Manage a newspaper" , "doctor" , "Prepare text for publication" , "Make changes to (text)" , "What our boss does" .)
