Can two men, a naturalist and a poet, successfully navigate the dense, dangerous interior of Borneo to locate the elusive rhinoceros while contending with the harsh realities of the jungle? Redmond O’Hanlon, a naturalist with extensive regional knowledge, and poet James Fenton document their expedition into the heart of the Bornean rainforest. The narrative relies on their personal experiences, survival challenges, and the practical application of biological expertise against the backdrop of an unforgiving environment.

Critics and readers frequently note the balance between O’Hanlon’s erudite observations and the humorous, often chaotic nature of the expedition. Experts highlight this work as a significant contribution to travel literature, valued for its vivid prose and authentic depiction of the physical demands of exploration.
