“The horror! The horror!” These are Kurtz’s final words in Joseph Conrad’s “Heart of Darkness,” the story of a man who travels into the jungle to seek his fortune and who instead finds an all-consuming moral and spiritual wilderness. Conrad’s enduring tale served as a touchstone for many works of fiction inspired by its somber theme. This collection also includes an additional five of Conrad’s best stories: “The Secret Sharer,” “Youth,” “Typhoon,” “Karain: A Memory,” and “Falk: A Reminiscence.”
