After the end of the Second World War, the Nazi doctor Josef Mengele, known worldwide for cruel experiments and for sending thousands of people to the gas chambers at the Auschwitz concentration camp, lived on the run for 34 years, more than half of them in Brazil. Mengele escaped justice, the Israeli secret service, and Nazi hunters until his death in Bertioga Beach, in the state of São Paulo, in 1979. Hidden in Brazil, Mengele created his “Tropical Bavaria”, a place where he could speak German, maintain his beliefs, his friends, and his connection with the homeland. This was only possible thanks to a small circle of expatriate Europeans willing to help him until the end.
One such person, Austrian Liselotte Bossert, buried Mengele with false documents in order to keep his true identity hidden even after his death. When, in 1985, this fact came to light and the world finally discovered where Josef Mengele was, Liselotte was teaching at a German school in São Paulo, and one of her students was precisely Betina Anton, then six years old. The sudden disappearance of her schoolteacher, with no explanation given to the children, intrigued her forever. Decades later, as an experienced journalist, Betina decided to investigate the matter. But when she was reunited with Liselotte, she received threats for wanting to clarify a “dangerous case”.
