Onder de koppensnellers op Borneo

Two friends who have long lived abroad undertake hazardous expeditions into Borneo’s western interior, traveling with local guides to collect natural and ethnographic specimens and to prospect for precious stones. The narrative follows their riverine and mountain journeys through dense jungle, encounters with armed and secretive indigenous groups, episodes of betrayal, sudden pursuits and ambushes, and the practical hardships of exploration. Along the way they document customs and landscapes, confront moral and physical tests, and press on through peril toward a final, hard-won return from the wilderness.
