It turns out that Pixar doesn’t have the monopoly on epicurean rats living in Paris. Long before rodent Rémy was tasting stew in the 2007 movie Ratatouille, an entire vermin population had to contend with an unwanted move when Paris’ wholesale market left its central location at Les Halles. The Road to Rungis, a young adult novel by Christian Léourier, recounts the story of Gaspard and his son Achille, two uprooted rats who follow their food source from Les Halles to Rungis market, just south of Paris, in 1969.
