Jules Verne - Das Karpathenschloss (deutsche Ausgabe - German Edition)

In the village of Werst in the Carpathian mountains of Transylvania (then part of Austria-Hungary, today part of Romania), some mysterious things are occurring and the villagers believe that Chort (the devil) occupies the castle. A visitor of the region, Count Franz de Télek, is intrigued by the stories and decides to go to the castle and investigate and finds that the owner of the castle is Baron Rodolphe de Gortz, one of his acquaintances, as years ago, they were rivals for the affections of the celebrated Italian prima donna La Stilla. The Count thought that La Stilla was dead, but he sees her image and voice coming from the castle, but we later on find that it was only a holographic image. (from Wikipedia)
