Penguin Classics presents Joseph Conrad's Heart of Darkness, adapted for listening and available as a digital audiobook as part of the Penguin English Library series. Read by David Threlfall, the star of the hit Channel 4 series, Shameless.

The mind of man is capable of anything - because everything is in it, all the past as well as all the future. What was there after all? Joy, fear, sorrow, devotion, rage - who can tell? But truth - truth stripped of its cloak of time. Let the fool gape and shudder - the man knows, and can look on without a wink; Marlow, a seaman, tells of a journey up the Congo. His goal is the troubled European and ivory trader Kurtz.

Worshipped and feared by invaders as well as natives, Kurtz has become a godlike figure, his presence pervading the jungle like a thick, obscuring mist. As his boat labours further upstream, closer and closer to Kurtz's extraordinary and terrible domain, so Marlow finds his faith in himself and civilization crumbling.

Conrad's Heart of Darkness has been considered the most important indictment of the evils of imperialism written to date. Part of a collection of vintage recordings taken from the Penguin Archives, the Penguin English Library series features affordable, collectable, quality productions - perfect for on-the-go listening.
