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, Sar Dubnotal, the Great Psychagogue, his disciple Rudolph, his medium the beautiful Gianetti Annunciata, and his trio of assistants, Frank, Frejus and Otto, pursue the beautiful but deadly Countess Azilis de Treguilly 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 Sar Dubnotal series features one of the first superheroes of the supernatural. Like John Silence, Carnacki and Simon Iff, Sar Dubnotal mixes modern science with occult spells and ancient mysticism, all in a horror-fraught atmosphere of grisly murders and vengeful wraiths.
