From the haunted castles of ancient Brittany to the mist-shrouded streets of Whitechapel, from the palaces of Marseilles and Tunis to the back alleys of Montmartre, Sâr Dubnotal, the Great Psychagogue, his disciple Rudolph, his medium the beautiful Gianetti Annunciata, and his trio of assistants, Frank, Fréjus and Otto, pursue the beautiful but deadly Countess Azilis de Tréguilly and her Svengali-like master, the evil, sadistic hypnotist Tserpchikopf, Prince of Crime, Master of the Chessmen, who turns out to be none other than ... Jack the Ripper! Published anonymously in 1909 in a series of French pulp magazines, the Sâr Dubnotal series features one of the first superheroes of the supernatural. Like John Silence, Carnacki and Simon Iff, Sâr Dubnotal mixes modern science with occult spells and ancient mysticism, all in a horror-fraught atmosphere of grisly murders and vengeful wraiths.
