In the aftermath of a devastating car crash that claims the life of her husband, Pete, Boston journalist Shelby Naylor finds her world upturned. Once known for her fluff pieces, Shelby's recent shift towards hard-hitting investigative journalism takes an unexpected turn as she grapples with her physical recovery, which threatens to rob her of her passion for horseback riding. In the midst of her healing journey, she reluctantly embraces her late husband's obsession - a high-powered police scanner. Initially a nuisance, the scanner quickly becomes a lifeline, opening a clandestine world of radio waves, through which she stumbles upon the volatile exchanges of a man named David Birkwell. His impassioned arguments with his wife Brenda, coupled with intimate conversations with a potential mistress, Alexia, captivate Shelby's attention. When Brenda suddenly disappears, the private conversations Shelby has overheard morph into potent evidence of foul play. Driven by her pursuit of justice, she presents her findings to the authorities, propelling David into the harsh glare of a murder investigation. As the district attorney charges David with murder, Shelby finds solace in the company of Tom Williams, Pete's friend and business partner, who harbors a gentle affection for her. However, her involvement in the case is far from over. A torrent of fresh evidence emerges, casting doubt on her initial assumptions and revealing unsettling links to Pete and Tom. With each revelation, Shelby is drawn deeper into a web of deceit and danger, her life hanging in the balance as she edges closer to uncovering the truth. In this thrilling narrative of suspense and intrigue, Shelby Naylor's quest for justice becomes a perilous journey into a world where secrets lurk behind every radio wave.
