When Commissaire Jean-Baptiste Adamsberg, the chief of police in Paris's seventh arrondissement, is called to the scene of a ghastly and highly unusual murder, he thinks it can't have anything to do with the nine pairs of shoes and severed feet discovered outside of London's Highgate Cemetery just a few days earlier. With the help of the murdered man's gifted physician, Adamsberg delves into the victim's disturbed psyche and unexpectedly finds himself on a path that takes him deep into the haunted past of Eastern Europe, where a centuries-old horror has come to life and is claiming victims far and wide.
