No sooner do Judy and her FBI husband Peter Dobbs arrive in Washington, D.C., than Judy is knee-deep in mystery and suspense. It all begins quite innocently-the old Senate Office Building is being plagued by mice, and Judy's beloved cat Blackberry, rejected at the motel where she and Peter are staying, is elected official mousecatcher. There is only one problem-Blackberry has disappeared. Who let Blackberry out of the motel room and why? The owner, paralyzed by fear, refuses to talk-that is, until his own daughter vanishes-then he readily agrees to cooperate with the FBI and a Senate Committee investigating organized crime. But there is more involved in this labyrinth of intrigue than even Judy suspects. As she tours the Capitol building, she overhears a strange whisper which only can mean one thing-more danger! The life of a prominent Senator has been threatened, and Judy is suddenly faced with a great challenge to her cherished ideals of freedom and democracy. As the intricate pattern of the situation begins to emerge, Judy finally finds a solution both to her own dilemma and to a far larger and more perplexing situation.
