A nurse during World War II, she encounters a dying ball turret gunner known only as Technical sergeant Garp that being the only sound he is capable of uttering who was severely brain damaged in combat. Unconstrained by convention and driven by practicality and her desire for a child, Jenny is able to rape Garp due to his priapism, thus impregnating herself. She names the resultant child after Garp and raises him on her own.Garp grows up, becoming interested in wrestling and fiction writing, topics his mother has little interest in. Garps writing piques the interest of the daughter of the schools wrestling coach, Helen Holm. She is wary of him. Jenny also observes Garps interest in this regard and is intellectually curious about it, having little more than clinical interest in sex herself. She offers to procure a prostitute for Garp, and after engaging the two of them in conversation on the subject decides to write a book on her observations of lust and human sexuality. ........
