Today's guest is Sarah Jane Stratford. Her first novel, Radio Girls, was based on the early days of the BBC and its pioneering talks producer, Hilda Matheson. Red Letter Days, her newest novel, continues that tradition by similarly highlighting a little known but influential woman in media set during the 19 fifties Red Scare and inspired by the real life TV producer Hannah Weinstein, Red Letter Days reveals the untold story of women who escaped the Hollywood blacklist. Sarah joined me today to talk about the inspiration for Red Letter Days and the research involved in writing about the Red Scare.
