About the book (from Wikipedia):
The Carpathian Castle (French: Le Château des Carpathes) is a novel by Jules Verne first published in 1892. It is possible that Bram Stoker took inspiration from this for his 1897 novel Dracula. Due to castle aspect and local toponymy, it is assumed that Colț Castle (ro) in Hunedoara county inspired Jules Verne.
In the village of Werst in the Carpathian mountains of Transylvania, some mysterious things are occurring and the villagers believe that Chort (the devil) occupies the castle. A visitor to the region, Count Franz de Telek, is intrigued by the stories and decides to go to the castle and investigate. He finds that the owner of the castle is Baron Rodolphe de Gortz, with whom he is acquainted; years earlier, 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 hears her voice coming from the castle. It is later revealed that it was only a projected still image accompanying a high-quality phonograph recording.
