What Happens, Part by Part (Contains Spoilers)
On the Thames
On a boat on the Thames, Marlow tells his companions about his voyage into Africa, reminding them that Britain, too, was once “one of the dark places of the earth.”
The company
Marlow gets a job captaining a river steamer for a Belgian company. At the stations, he sees Africans worked to death in chains and greedy, incompetent agents. He hears repeatedly about Mr. Kurtz, the company's most successful ivory collector.
Up the river
Marlow's steamer is damaged and repairs take months. Traveling upriver, the boat is attacked, and his helmsman is killed. At the Inner Station, a young Russian tells him that Kurtz is worshipped by locals, and Marlow sees heads on stakes around Kurtz's house.
Kurtz
Kurtz, gravely ill, is carried aboard. He has written a report on “civilizing” Africans, scrawled with the words “Exterminate all the brutes!” On the journey back, he dies, whispering, “The horror! The horror!”
The lie
Back in Europe, Marlow visits Kurtz's fiancée, who idolizes him. When she asks for Kurtz's last words, Marlow lies and tells her that he spoke her name.
