Migrate in order to see French detective (7)
I believe the answer is:
maigret
'french detective' is the definition.
'maigret' can be an answer for 'detective' (I've seen this before). I am not certain of the 'french' bit.
'migrate in order' is the wordplay.
'in order' indicates an anagram (the letters in a new order).
'migrate' anagrammed gives 'MAIGRET'.
'to see' acts as a link.
Can you help me to learn more?
(Other definitions for maigret that I've seen before include "Fictional detective" , "Simenon''s detective-superintendent" , "cracker?" , "Simenon's Inspector" , "Georges Simenon's detective" .)
