Klara’s fate is particularly tragic because it is clear the knocks are coming from someone who is worried about her and trying to find her. Yet because of Klara’s obsession, she instead interprets the knocks as Simon calling her to him, reinforcing how her thoughts take on a life of their own and lead her to kill herself. Benjamin’s use of the word “star” also has a double meaning here—Klara isn’t a star in the sense of celebrity or popular stage performer, but instead the word implies that in death, her consciousness leaves her body and returns to the universe.
