The narrative structure of Red Dragon and its sequel, The Silence of the Lambs , underscores that vision. In both books, the FBI is struggling with an insoluble case involving a serial killer. Baffled, they turn to Lecter, which establishes him as unique. Even the cops consult him. The really clever thing is that author Thomas Harris isn't too specific about Hannibal.
Information is scanty, and filtered out randomly throughout the two books.
We see Hannibal manipulating agent Clarice Starling with his teasing, malicious mindgames. Even in a maximum security prison he does not seem a prisoner. He's more like a force of nature, biding its time before the next orgy of blood begins. Although both agents go to him for help, Hannibal never really helps. He toys with them, setting them up to fail, revelling in his superior knowledge and insight.
