tricked by the elusive "Great Unknown". Von Wenk goes undercover at a gambling den, where he encounters a disguised Dr. Mabuse. Mabuse attempts to hypnotize von Wenk, but he effectively resists. Mabuse flees. Von Wenk, quickly regaining his faculties, gives chase through the city, but the doctor escapes. Boarding a taxicab driven by Georg, von Wenk is gassed, robbed, and set adrift in a rowboat. Dr. Mabuse realizes that Hull is assisting the state prosecutor, and resolves to eliminate both men. Carozza, who has been romancing Hull on Mabuse's orders, lures the young man to a new illegal casino; when von Wenk calls in the police to raid the place, Carozza, Hull and a police bodyguard exit through the back door, where Georg awaits. He kills Hull, but Carozza is caught and jailed. Von Wenk questions her for information about the "Great Unknown", but she refuses to speak. Von Wenk enlists the aid of Countess Told (nicknamed the "Passive Lady"), an aristocrat bored by her dull husband and seeking thrills wherever she can find them, to try to get the information by trickery. The Countess is placed in the same cell, an apparent victim of another raid, but Carozza is not fooled. Carozza reveals only her great love for Mabuse, ensuring her silence. The Countess, moved by Carozza's passion, tells von Wenk that she cannot continue to assist him. Dr. Mabuse does nothing to extricate Carozza from jail. He instead attends a séance where he meets Countess Told, who (while under his hypnotic influence) invites him to her house. Once there, Mabuse, taken by the Countess's beauty, decides to display his power by telepathically inducing her husband, Count Told, to cheat at poker. His guests are outraged when they detect it, and the Countess faints. Dr. Mabuse uses the distraction to abduct her and imprison her in his lair. Part II Inferno: A Game for the People of our Age (Inferno: Ein Spiel von Menschen unserer Zeit) A sick and disgraced Count Told seeks the help of Dr. Mabuse to treat his depression; Mabuse uses this chance to isolate the Count in his manor and cut off any inquiries about the Countess's whereabouts. The Count's condition worsens, and he is tormented by hallucinations. Meanwhile, Carozza is moved to a women's prison and again interrogated by von Wenk. Fearing betrayal, Mabuse sanctions Carozza's death. Georg smuggles poison to her cell, which
