Near the end of the novel, in Chapter 62, Pelagia receives a photograph from Günter Weber and written on the back is a passage in German from Goethe's "Faust", Gretchen am Spinnrad, which is also a popular German Lied, set to music by Schubert. It reads:
Meine Ruh ist hin, Mein Herz ist schwer, Ich finde sie nimmer und nimmermehr.
Which translates as:
My peace is gone, My heart is sore [lit. "heavy"], I will find it never and nevermore.
