- Clarendon, Dr. Alfred Schuyler
- In “The Last Test,” a physician who is appointed medical director of the San Quentin Penitentiary by the governor but is later removed because of his handling of the case of a prisoner stricken with black fever, whose death prompts fear of an epidemic in San Francisco. Clarendon is in fact not trying to find a cure for black fever at all, but—under the evil influence of the mysterious Surama, who acts as his assistant—is attempting to produce a serum that will induce a disease that will kill all humankind. He tries to inject his sister, Georgina, with the serum; prevented from doing so, he injects himself instead. Fearing the outcome, he destroys himself and his clinic by fire.
