Beverly Katz works in the Hair and Fiber section, she is very good at her job, and seems to have a somewhat bantering relationship with Jack Crawford, when examining a note found in Hannibal Lecter's cell for hairs, she says to Crawford "See you later, Love your hair" since his hair has become disheveled from a helicopter trip.
"She cocked her head and looked at it with her bright robin's eye.
Crawford could see her lips moving. He knew what she was saying.
That's what she always said."
Jack Crawford says that she knows Mah-Jongg and says that "She's sharp".
She is a key part of investigations, and after examining the note found in Hannibal Lecter's cell she is able to make field recommendations: "The tears at the end of the pieces wandered off the perforations, if we find the roll in somebody's possession and he hasn't torn it again, we can get a definite match. I recommend issuing an advisory now, so the arresting officers will be sure to search for the roll."
Beverly lives with someone called Saul (the nature of their relationship is unspecified) who is going to cooking school, and Beverly invites Will Graham to come over and let Saul practice on him.
