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 can mean mother).
'with' means one lot of letters go next to another.
'wild' indicates anagramming the letters.
'tiger' with letters rearranged gives 'igret'.
'ma'+'igret'='MAIGRET'
'finding' acts as a link.
(Other definitions for maigret that I've seen before include "Fictional detective" , "Simenon's Inspector" , "Georges Simenon's detective" , "cracker?" , "Policeman" .)
