Rosamond Gregory is Lucian Gregory’s sister. At the beginning of the novel, Gabriel Syme notices her beautiful red hair and chats with her for several minutes about poetry and her brother’s anarchism. He thinks about her hair periodically over the course of the novel, and in its very last sentence, he watches her cut lilacs (which generally symbolize love and rebirth). Syme’s romantic interest in Rosamond Gregory gives him a certain, constant goal to yearn for, which contrasts with the nightmarish moral uncertainty that plagues him throughout the rest of the novel.
