Perfect husband described in this way (4)
I believe the answer is:
thus
'this way' is the definition.
(thesaurus)
'perfect husband described in' is the wordplay.
'in' says the answer is hidden in the clue.
'THUS' can be found hidden inside 'perfect husband described'.
(Other definitions for thus that I've seen before include "Therefore, hence" , "'So, therefore (4)'" , "as indicated" , "Shut (anag.)" , "Like so" .)
