Miss Hewitt is the personal secretary of county district attorney Frank Scanlon. She first appeared in "Programmed for Death", the third episode of the TV series, where she was played by American actress Sheila Leighton. Although this was her sole appearance in the series, she later reappeared in the tie-in novel The Green Hornet: The Case of the Disappearing Doctor. Decades later, the character would reappear in "Fang and Sting" in Moonstone Books' Green Hornet short story anthology The Green Hornet Chronicles.
