Love place to sleep niece arranged in dutifulness (9)
I believe the answer is:
obedience
'dutifulness' is the definition.
(thesaurus)
'love place to sleep niece arranged' is the wordplay.
'love' becomes 'o' (In tennis, 'love' means 'zero').
'place to sleep' becomes 'bed' (I've seen this before).
'arranged' indicates anagramming the letters.
'niece' anagrammed gives 'ience'.
'o'+'bed'+'ience'='OBEDIENCE'
'in' is the link.
(Other definitions for obedience that I've seen before include "Vow" , "following instructions" , "Compliance with rules" , "Respect" , "Brother may swear this" .)
