Perfect husband embraces like that (4)
I believe the answer is:
thus
'like that' is the definition.
(as in 'like so')
'perfect husband embraces' is the wordplay.
'embraces' says the answer is hidden in the clue (I've seen 'embracing' mean this (the solution is embraced by words in the clue)).
'THUS' can be found hidden inside 'perfect husband'.
(Other definitions for thus that I've seen before include "It follows" , "Like so" , "In this way" , "an original Christmas gift" , "Consequently" .)
