The story moves forward to a Victorian era London where Abdul Alhazred is conducting a séance. However, it appears to be more hypnotism than Spiritualism and the medium is trying to extract information from his clients. Luckily the guest are undercover police officers but an attempt to arrest the villains reveals them to be clockwork automata. They were all created by Prof. Philo Thynne who left his position at London University's Mechanical Engineering Department to run the scheme, not for his personal gain, but to build a device to protect him from Stickleback, with whom he had previously had some kind of contact.
