He investigates and finds the Chelsea home of the Brotherhood, where Singleton and others have been murdered. In the basement, surrounded by crosses made of twigs, he finds Professor Abraham Van Helsing, living like an animal, who insists they must free him at once. Van Helsing explains that he was employed as a folklorist by the Brotherhood to investigate vampires. He eventually found Dracula, and was released with a message to the Brotherhood: he would come to them if invited, but only if provided with property. Frightened by Van Helsing's ordeal with Dracula, they sent Jonathan instead, and imprisoned Van Helsing. Seward attempts to explain this to Mina but she is skeptical.
