Fritz has just arrived in a place so secret it isn't shown on any map. Even mentioning its name is forbidden. Mail is censored. Visitors are not allowed. When Fritz-known as Franklin until he came here-learns that this remote spot in the New Mexico mountains is the site of a heavily guarded government laboratory, his curiosity takes over. Exactly what are his father and other scientists working on at the lab? It's common knowledge that their top-secret project has something to do with the war in Europe and the Pacific, but what? Fritz is determined to find out. With the help of Kathy, his seventh-grade classmate, Fritz searches for clues. He records each observation and every rumor in a notebook he doesn't dare let out of his sight. His sleuthing-and trying to avoid, evade, or outwit the two bullies who have it in for him-keeps Fritz busy. But he finds time to explore the area with his Spanish-American friend Manny, to become involved in a prank with unintended consequences, and to get into serious trouble when he and Manny show too much interest in a restricted area.
