The story begins in 1951. John Rivers is speaking to a friend about his encounter with the Maartens family. In 1921, Rivers, who was extremely sheltered by his widowed mother, is employed as a lab assistant to Henry Maartens, after receiving his PhD. Dr. Maartens is a Nobel Prize–winning, socially awkward physicist. Rivers is invited to live in Henry's home until he finds his own place, but the Maartens family soon develops a fondness for Rivers, and insists that he stay with them. Rivers develops respect and fondness for the family, regarding Henry as a genius and his wife Katy as a goddess. As his attraction towards Katy grows, Rivers is simultaneously victimized by her 15-year-old daughter Ruth. After being rejected by a 17-year-old football player and scholarship winner, Ruth tries to be a dramatic poetess. She fantasizes that she is in love with Rivers to find solace and an outlet for her emotions.
