Detective finding mother with wild tiger (7)
I believe the answer is:
maigret
'detective' is the definition.
(I've seen this before)
'mother with wild tiger' is the wordplay.
'mother' becomes 'ma' (Ma is another word for mother or mum).
'with' means one lot of letters go next to another.
'wild' is an anagram indicator.
'tiger' anagrammed gives 'igret'.
'ma'+'igret'='MAIGRET'
'finding' is the link.
(Other definitions for maigret that I've seen before include "Fictional detective" , "Simenon's Inspector" , "Georges Simenon's detective" , "cracker?" , "Policeman" .)
