Everett of "An Ideal Husband" (6)
I believe the answer is:
rupert
'everett of an ideal husband' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for rupert that I've seen before include "Prince" , "Mary Tourtel's bear" , "Cartoon strip bear" , "Comic strip bear" , "It's bought unseen (1,3,2,1,4)" .)
