Heart Of Darkness Audiobook. The story of the civilized, enlightened Mr. Kurtz who embarks on a harrowing "night journey" into the savage heart of Africa, only to find his dark and evil soul. These are actual events and people that Conrad met or heard about during his many far-flung travels. In portraying men whose incredible journeys on land and at sea are also symbolic voyages into their own mysterious depths, these two masterful works give credence to Conrad's acclaim as a major psychological writer.
