Journey without Maps (Classic, 20th-Century, Penguin)

White men were not particularly welcome in Liberia when Graham Greene made it the object of his first journey outside Europe. Drawn by the evident seediness of a republic founded for released slaves and, above all, by the darkness and mystery which Africa has represented for some people in their unconscious minds, he travelled with a chain of porters from the border of Sierra Leone across the headwaters of several rivers and down to the coast at Grand Bassa.
