African apocalypse tells the story of a young man's journey across Africa in search of a colonial killer. It is an urgent and timely non-fiction retelling of Joseph Conrad's Heart of Darkness. Armed with a copy of Conrad's classic novel, British-Nigerian Oxford University student Femi Nylander goes in search of the meaning and legacy of colonial horror in West Africa. He discovers the unknown story of a French army captain, Paul Voulet, who descended into unspeakable barbarity in the conquest of Niger at the very moment Conrad wrote his book. Femi finds communities still traumatised by the century-old violence of Voulet.
