 The narrator tells us also that Franz will eventually be “guilty of worse sins than avunculicide", a section that was inserted by Nabokov much later with historical hindsight when he prepared the English translation.The author and his wife, though not directly identified, are portrayed near the end of the novel as a happy, but "puzzling" couple who are also vacationing in the Baltic resort and speaking in a foreign tongue; they have a butterfly net, which is taken for a mosquito net by Franz and a shrimp net by Martha, but Dreyer identifies it correctly.Later Franz sees them again and feels they are talking about him and know "everything about his predicament".
