Dodsworth by Sinclair Lewis

Three days of museums, of art galleries, of palaces, of the Zoo. They went to Sans Souci, where Fran talked of Voltaire (she really had read "Candide") and Sam thought in a homesick way of the Sans Souci Gardens development in Zenith and snapped at himself that it was time to clinch with Fran, to make her come home and begin a new life of "making things."

They saw nothing of Kurt von Obersdorf--he merely telephoned to them eight or ten times and made them go out and see things. He so insisted that they see Molnar's "Spiel im Schloss" that they sulkily went, though by now Sam had convinced himself that he was right in thinking he didn't care greatly for plays in a language he didn't understand, and though Fran, exhausted by the florid endearments which had been poured upon her at a women's tea given by Frau Dr. Biedner, for once in her life wanted to go to bed.
