Die Elixiere des Teufels: Nachgelassene Papiere des Bruders Medardus, eines Kapuziners
By E. T. A. Hoffmann
Brother Medardus, a gifted Capuchin preacher, tastes a forbidden elixir said to come from the devil's temptation of Saint Anthony. He leaves the monastery and falls into a nightmare of crimes, mistaken identities and a double who seems to live out his sins. Told as his own confession, it is one of the great Gothic novels in German.
