Archie suggests that Veronica should get a dog who's a pet instead of a prize animal for dog shows. A famous animal trainer provides the Lodges with a cute, well-trained dog -- except he's been trained to steal people's valuables and even kill on the trainer's command.; While staying at Mr. Lodge's beach house, Archie and Veronica discover that a seemingly innocent frisbee thrower is there to spy on a top-secret government project, and that the frisbee he throws is a deadly steel weapon.
