Caviar" is a peculiar short story, of a married couple involved in a "little experiment."  The short story is narrated by the husband, Mr. Trimpie, a fisherman by trade, who has never been to college but reads science books and magazines. The wife, Marie, after many years of marriage decides she wants some "offspring."  The pair repeatedly try to have a child, but Marie cannot get pregnant. The couple decide to go to a doctor and ask about a test-tube baby. Dr. Ziss, a very young man, tells them that Marie’s ovaries are shot, and that test-tube reproduction is impossible. Dr. Ziss questions the couple, he asks, "have they considered a surrogate mother?"  As he has already contacted a woman on their behalf, should they be interested. For ten thousand dollars plus hospital costs, they agree to have Wendy, a medical school student, as their surrogate mother. Wendy is artificially impregnated by the doctor and becomes very close to the couple. One day, while Marie is working, Wendy and Mr. Trimpie engage in a sexual relationship. Marie never finds out about the incident. Mr. Trimpie, while visiting Wendy after the baby is born, finds Dr. Ziss at her house and realizes he has been deceived. Wendy says she won’t stay with him because they move in different circles. Enraged, Mr. Trimpie assaults Dr. Ziss, and is arrested by the police. Back to his house, Marie won’t let him in, and he ends up at the dock gutting a fish full of "eggs in her."
