In the Heart of Africa

"In the Heart of Africa" is a classic African explorer biography by Samuel White Baker. 

The story developed during "In the Heart of Africa" is summarised at the beginning of the novel by the narrator and protagonist:
"In March, 1861, I commenced an expedition to discover the sources of the Nile, with the hope of meeting the East African expedition of Captains Speke and Grant, that had been sent by the English Government from the South via Zanzibar, for the same object. I had not the presumption to publish my intention, as the sources of the Nile had hitherto defied all explorers, but I had inwardly determined to accomplish this difficult task or to die in the attempt."
