Ingo and Lani are moving to Washington DC to live as a family with Jim, Pat, and their pets. The arrival of Ingo and Lani at Union Station in Washington DC turns on Ingo's patriotic emotions, and he sets a goal for himself to help make the world a better place. The greatness and importance of the town's sites seen on the way to their new home strengthen his decision. Soon, he finds himself in the middle of a dangerous situation and ends up being the unintended victim of poisoning. Pat, Lani, and Jim act quickly and save Ingo, but their friend and his two children are in permanent danger as the spies have an accomplice implanted in their household. They live now in a lovely close-knit small, and multi-racial community in the neighborhood of Shaw. The neighbors are friendly and help each other in need. Ingo recovers well from the poisoning and, due to his abilities, is used to safeguard the children in the father's absence. The gravity of the events brings the whole group closer together. After laboratory testing, surveillance work, amateur forensics, and caution exercised by all of them, they have evidence and are ready to act. After Alex's second child is victim to the spies' aggression, he contacts the authorities with the support of his friends Jim and Lani. Alex, the scientist, is so impressed with Ingo's abilities that he proposes the Police and FBI use Ingo as the contact with the spies, which leads ultimately to the neutralization of the spy ring. Ingo's performance is highly appreciated, and he has the gratitude and admiration of the group. He receives from the authorities full recognition for his contribution, 'employment' offers as a dog trainer, and long-term compensation. Ingo has achieved his life goal—from Book 1—of a good life and having the love and friendship of his master but also fulfilled his self-imposed patriotic duty 'to make the world a better place.' As the last book of the Ingo series, the book ends with Ingo's more profound understanding of what it takes to make the world a better place.' But he's a dog, after all. He is now waiting for a helping of juicy steak.
