Fix where Blythe admits to spying? (7)
I believe the answer is:
implant
'fix' is the definition.
(thesaurus)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for implant that I've seen before include "Establish" , "New element in trap" , "get fixed" , "Inculcate; embed" , "Bristol may get boost from this" .)
