On October 6, 2003, writer Lily Koppel came across a New York dumpster filled with old steamer trunks from the jazz age. Digging through the relics, she discovered a red leather diary. Once owned by a teenage Florence Wolfson, the writing conjured a vivid portrait of Manhattan’s literary scene and arts culture of the 1930s. Enlisting the help of a private investigator Lily discovered that Florence was still alive, at age 90. Lily tells her story in her new book, The Red Leather Diary: Reclaiming a Life through the Pages of a Lost Journal.
