In the late 1960s, a man turned up in the Brazilian state of Acre, deep in the Amazon region. He was wearing a loincloth and a feather, carried a bow and claimed he was Tatunca Nara, chief of the Ugha Mongulala. No one had ever heard of an Indian tribe with that name. In addition, the man bore no resemblance whatsoever to an Indian. He was white and spoke with a strong French accent.
