I doubt Thomas Harris will write a sequel to Hannibal. I'd be happy if he did, but unless he's already been writing it and is almost finished, I doubt it's coming. He is a 76 year old man. Hannibal was notorious for not being well received by some people (although Stephen King found it better than Silence of the Lambs).
I could see a sequel called Clarice. Hannibal Lecter dies and she's on her own. She returns to her former life, her former stomping grounds, meets up with Ardelia again, but this time, Clarice is the Hannibal Lecter-type character, filling in his shoes now. She's the brilliant one now. She's no longer the mouse, the mistreated one, as she was in Hannibal. She's calling the shots, maybe she kills, maybe she tries to become like her old self at the same time. I wouldn't really care to see more of Hannibal, but I wouldn't mind more of Clarice.
