In February 1950 an Indian discovered the remains of a camp on the Tamouri River in French Guiana. Of the few items left there, only a rifle seemed worth taking back to the village. But there was also a diary belonging to 23-year-old Raymond Maufrais , who had set out the previous year to cross the Tumucumaque Mountains. John and Heather Harrison , who have travelled through the inhospitable region, recount the story of Raymond Maufrais and his father's 12-year search for his son.
