Vivian Dalton prides herself on her intuition. She just knows people, especially the people in her town of Wooster, Ohio. Of course, working as a switchboard operator at Bell gives her an edge: She's technically not supposed to listen in on phone conversations, but all the girls do it. It's never done anyone any harm—until Vivian overhears a secret that threatens to destroy her reputation and upend the fragile stability of her life. But Vivian refuses to go down without a fight: She decides to take matters into her own hands, to ferret out the truth no matter how painful—and no matter who else goes down with her.
