Director: Michael Lange
A reminder of Mulder's first case just after he graduated the FBI Academy. Working for the Violent Crimes section he helped in the capture of John Barnett who carried out a series of violent bank robberies and left notes for Mulder at the crimes scenes. During Barnett's arrest Mulder following FBI protocol hesitated and another agent died as a result. Barnett who vowed to 'get' Mulder was sentenced to life but died in prison in 1989. When a handwriting expert examines the latest note, he concludes it was written by Barnett recently. Mulder interviews Barnett's cellmate Joe Crandall, who swears that he saw Barnett alive on the night he supposedly died. When the prison doctor Dr Ridley who signed Barnett's death certificate turns out to have lost his license for using his research into the child disease Progeria, premature ageing, to conduct age-reversal experiments. Mulder speculates that Barnett may have been one of Ridley's guinea pigs and could have the perfect disguise, youth.
Mulder is contacted by Deep Throat who explains that the government funded Ridley's age reversal experiments and now that Barnett has stolen his work, the government is bargaining with him to get their hands on the information in return for his immunity.
Scully: Mulder, I know what you did wasn't by the book.
Mulder: Tells you a lot about the book, doesn't it?
