Characteristic of the eight stories "The Occupied House," "Letter to a Young Lady in Paris," "The Feme," "Omnibus," "Headache," "Circe," "The Gates of Heaven," and the title story "Bestiary" is their respective starting point: everyday environment, ordinary people, and events. The style of narration is a precise, realistic, seemingly artless-naive account, during which the reader's anxious tension continually increases and ultimately, in the same tone as if it were natural, the sudden intrusion of the unheard-of, profoundly shocking into the "normal" world.
