Inspector Mirouet and his wife have sex, but she is left unsatisifed because his attention was focused on a case of four murdered anthropologists. Inspector Mirouet suspects an Indigenous Brazilian boy named Emile, who is the bastard son of an anthropologist. Emile came to Paris to find his dad. Inspector Mirouet wants to adopt Emile. Emile and Inspector Mirouet talk about anderology and the process of cooking with a fire. Later Emile relates to Inspector Mirouet his discovery that anthropologist Lévi-Strauss did not know the meaning of “reyuno” and the effects this lack of knowledge has on his work. Emile later tells Inspector Mirouet of further mistakes in the field of anthropology and the ramifications those have. He then requests to join medical school. Emile figures out that the four anthropologists died from a slow acting disease that resulted from the consumption of children’s brains. Emile wants to rebuild his native society using the anthropological theories that he has studied. While Inspector Mirouet is away in Marseilles for work, Madame Mirouet talks with Emile and both are reading books about Brazil. Madame Mirouet then reads two passages from Samuel Taylor Coleridge that remind her of Emile. The two then have an affair. Later Emile and Madame Mirouet stand looking out a window.
