This very well written book open the doors of a segment of the African history unknown for most of the people. This is a shocking research that show us how a huge area in Africa became an ivory and rubber hell where the brutality, cruelty and ambition of the Belgium king and his employees reduce the native population to a slave condition by force but also shocked me the doble morale of those people who denounced the crimes and exposed the reality of the colony and the other face of King Leopold so strongly but said nothing or almost nothing against the British, French, German and Dutch Empires that were committing the same or worst crimes in their colonies at the same time applying the same policy of robbery and cruelty as King Leopold in his Free State of Congo later known as the Belgium Congo.
