Set in 1930s British-ruled Sarawak, the narrative follows John Truscott, an eager and idealistic young Englishman who arrives in the lush Bornean jungle to serve the colonial administration. Appointed by the pragmatic Resident Henry Bullard, John is tasked with bringing British
civilization, law, and education to the remote Iban tribes. However, he quickly realizes that the true heartbeat of the territory lies not in the stiff formalities of the British club, but deep within the untamed rainforest.To help him assimilate and master the local dialect, Henry presents John with a "sleeping dictionary"—a native companion whose duty is to teach him the language by day and share his bed by night. John is initially assigned Selima, a fiercely intelligent, striking, and spirited young Iban woman. Though John resists the custom due to his modern sensibilities, the two soon forge an undeniable connection. What begins as a practical arrangement rapidly transforms into a passionate, secret romance. Selima opens John's eyes to the richness of Iban culture, challenging his Eurocentric worldview and making him question the oppressive nature of the colonial regime he serves.Their idyllic romance is abruptly shattered by the rigid social codes of the British elite. When Selima becomes pregnant, the scandal threatens John's career, social standing, and freedom. Unwilling to accept the child or the relationship, the colonial authorities intervene decisively. Henry Bullard, despite his personal sympathy for John, is forced to uphold colonial law. Selima is banished back into the deep jungle, and in a devastating move to protect John’s reputation, he is coerced into marrying Aggie, the sweet and naive daughter of a wealthy British planter.Heartbroken and disillusioned, John lives a miserable
domestic life with Aggie, haunted by the memory of Selima. He tries to immerse himself in his administrative duties, but the hypocrisy of the empire weighs heavily on him. Years pass, and John discovers that Selima survived in the jungle and is now married to a local chieftain. Driven by lingering passion and a desire to reclaim the life that was stolen from them, John risks everything to find her. In a dramatic climax, John abandons his colonial post, his marriage, and his status. Rejecting the stifling expectations of British society, he chooses to live freely among the Iban people, finally reuniting with Selima and embracing a new destiny in the heart of Borneo.
