Thomas Harris first wrote about Lecter in his novel Red Dragon, which shows how Hannibal Lecter was caught by the FBI, and ends up using his intelligence to help the agent who caught him catch another killer named Francis Dolarhyde. Will Graham, the agent who caught Lecter, is at first very offended by Lecter's demeanor, but comes to appreciate his help when Lecter gives him insight into the way Dolarhyde's mind works. Dolarhyde believes that he is a god, and that he is unaffected by laws and rules.
