Belle da Costa Greene was hired by J. P. Morgan to curate a collection of rare manuscripts, books, and artwork for his newly built Pierpont Morgan Library. She became a fixture in New York City society and one of the most powerful people in the art and book world. But the more her reputation grew, the tighter Belle held onto a secret: She was passing for white. In the new book The Personal Librarian (Berkley/Penguin Random House, 2021), co-authors Marie Benedict and Victoria Christopher Murray tell the story of a remarkable woman, and the lengths to which she went to keep her secret. Benedict is a Boston College graduate and a bestselling author. Her previous titles include The Only Woman in the Room, The Mystery of Mrs. Christie, and Lady Clementine, among others. The Personal Librarian was chosen as the July GMA Book Club pick. Benedict and Murray talked about their collaboration with the Washington Post.
