This story, based on a true account, provides a unique perspective on the Holocaust. After Nazi's destroy the zoo animals, the zoo keeper and his wife use the animal houses as part of an underground operation to help escaping Jews. The story is not fictionalized, so is not extremely engaging but does offer interesting details. The zoo setting is a clever background for the author's exploration of the Nazi fascination with animal genetics and desire for pure animal strains as well as purity of the human race.
