SOMERSET MAUGHAM

je cherche le titre du roman ou de la nouvelle , ou du recueil de nouvelles d'où est extrait le passage suivant :
at seven fourty five in the dinner party to which a few friends had been invited , Mr Sunbury was busy being his own butler ; he poured some claret into one decanter and filled
a silver cigarette box with some sahibs his wife said she preferred to any other
titre (?) the dersinghams at home ???
Merci
