Second episode in the adventures of Tintin
Plot: Tintin is sent to Congo by Le Petit Vingtième to report on life in the former Belgian colonies. Instead he finds himself in the midst of tribal war and a coup led by the mafia to seize control of the diamond mining industry.
This is typical early Tintin fare; the natives are depicted as lazy and stupid and Tintin hunt and blow up endangered and exotic animals. Later editions have had most parts redrawn and most or all (depending on edition) of the hunting scene removed.
