Sarah (Jack's secretary)

RED DRAGON
Sarah is Jack Crawford's secretary. She orders a helicopter to transport Jack to collect the "Tooth Fairy" killer's note from Hannibal Lecter's cell at the Chesapeake State Hospital. She also transcribes dictation of an advertisement to be placed in The National Tattler which turns out to be from Lecter, and telexes it to CIA cryptography section.

She took a call from someone claiming to be "The Pilgrim" (which is Lecter's nickname for the "Tooth Fairy" killer) who was looking for Will Graham. The caller said he'd call again the next afternoon, by which time Sarah's desk had been fitted with a voiceprint spectrograph, tape recorders, and a stress evaluator. Sarah's role was to listen in on the calls and identify the voice of the person who called himself "The Pilgrim" and to signal to Beverly Katz to answer the call.

"HANNIBAL" (Four years before)
It is unknown if Sarah will appear before Season 4.
