Mystery in Rio

In this sequel to The Crossover Mystery, Jessica sees a small boat bobbing in the ocean as she is hang gliding from a mountain in Rio de Janeiro. She is overwhelmed by the sight of two men dressed in yellow shirts who dump a heavy bag into the ocean - reminiscent of the day she and David saw a man dump a body in the Sound on Long Island, New York. Is it the same dumping of dead bodies? She must find out? But how? The men have disappeared. Nevertyheless, she begins her quest with David at her side along with two Brazilinas who befriened her as they take on the Mystery in Rio.
