In this new expedition, which this time takes him to the heart of the Amazon jungle, Eliott Schonfleld retraces the unfinished journey of writer Raymond Maufrais. In 1949, the 23-year-old Resistance fighter set off alone across French Guiana to reach the legendary Tumuc-Humac mountains. Everyone tried to dissuade him from this madness, promising him hell and death, but he never turned away from his dream. Raymond Maufrais never returned from the expedition. If it hadn't been for the miraculous discovery of his notebook by an Indian, Emerillon, on the banks of the Tamouri River in 1951, we'd never have known what happened to him.
