MKO unravels the cover-up behind one of Africa's most consequential political crimes. In 1993, Abiola, the world's richest Black man, won a landslide victory that the military swiftly annulled. What followed was years of imprisonment, international negotiation and, ultimately, a death that has never been fully explained. The investigation draws on extraordinary access on all sides of the story: current and former Nigerian presidents, Nobel Laureate Wole Soyinka, Abiola's family and the U.S. delegate who was in the room when he died. Those implicated in the annulment also appear, offering conflicting accounts that unravel against one another. As the trail leads through broken promises from Washington and London, the question of who killed Abiola becomes inseparable from the question of who abandoned Nigerian democracy.
