Hannibal - Season 1 Episode 12

Following an offhand comment by Graham, a comb left in the chamber of Georgia Madchen, who accidentally sparks a fire inside her hyperbaric chamber and is burned to death. Angered, Graham deduces that several recent murders were all the work of a copycat patterning after recent serial murders, and that Georgia was killed because she may have remembered the face of whoever had killed Dr. Sutcliffe.
