Conrad's narrator Marlow, a seaman and wanderer, recounts his physical and psychological journey in search of the infamous ivory trader Kurtz: dying, insane, and guilty of unspeakable atrocities. Traveling upriver to the heart of the African continent, he gradually becomes obsessed by this enigmatic, wraith-like figure. Marlow's discovery of how Kurtz has gained his position of power over the local people involves him in a radical questioning, not only of his own nature and values but also those of western civilization.

Part of a major series of new editions of Conrad's most famous works in Penguin Classics, this volume contains Conrad's Congo Diary, a chronology, further reading, notes, a map of the Congo, a glossary and an introduction discussing the author's experiences in Africa, the narrative and symbolic complexities of Heart of Darkness and critical responses to the novel.
