How the sun fills Bess with rapture (12)

I believe the answer is:

blissfulness

'rapture' is the definition.
(thesaurus)

'how the sun fills bess' is the wordplay.
'how' is an anagram indicator (I've seen this in other clues).
'sun'+'fills'+'bess'='sunfillsbess'
'sunfillsbess' anagrammed gives 'BLISSFULNESS'.

'with' is the link.

I've seen this clue in The Irish News.
