Fix where your setter admits to espionage? (7)
I believe the answer is:
implant
'fix' is the definition.
(thesaurus)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for implant that I've seen before include "New element in trap" , "Insert in tissue" , "material (medical)" , "Bristol may get boost from this" , "Insert or fix into the body" .)
