Summoned to Whitehall in 1949, Laurens van der Post was told that in old British Central Africa there were two large tracts of country that London didn't really know anything about, and could he go in there on foot and take a look, please? Venture to the Interior is the account of that journey, a journey filled with adventure and discovery, flying from London across Europe and Africa, and after days in small aircraft, on foot across the mountains to the two lost worlds of central Africa.
