While exposing the remains of Flemish fascism twenty years after the War, Wonder tracks one man's descent into madness. Victor, a bewildered teacher, pursues a mysterious woman to a castle in a remote village. There he finds himself trapped among a handful of desperate individuals still living out their collaboration with the Nazis. As Victor's sanity begins to crumble, he poses as an expert on their messianic leader, who disappeared at the Russian front but whose return they believe imminent. The rich cadences of the prose and dense emotional texture of characters lost in complex moral labyrinths make Wonder a symphony only Claus could have composed.
