Sunday at 4 pm on KRCB FM Radio 91.Word by Word listeners (and mystery writers) will enjoy the conversation (and pick up a few writing tips), during Gil Mansergh’s informative conversation with Cara Black, the New York Times bestselling author of 19 Aimee Leduc murder mysteries. Each novel takes place in a different Parisian administrative district. Known as arrondissements, these 22 districts circle outward in a clockwise spiral from the center of Paris. Cara’s newest novel takes place in the 12th district, and we learn how this specific locale prompted her latest mystery, Murder in Bel Air.
