A convict on death row seeks a meeting with the prison warden. He tells the warden the story of how he went from a well known and respected professor of parapsychology to a brutal killer mimicking Jack the Ripper. He says that before the death of an associate of his, the associate said that at the moment of his own death the professor would become Jack the Ripper; the essence, morality, and drive that brought Jack the Ripper his grizzly fame would enter the professor’s body. The professor then says to the warden that at the moment the trap door opened and he is swinging dead, the same will happen to him. The warden will become Jack the Ripper. The professor even offers a couple of examples to prove the veracity of his statements. Is the warden doomed to become a prisoner in his own prison?
