Tintin and the Broken Ear

When thieves steal a fetish from a museum, Tintin travels to San Theodoros to recover it. The fetish is stolen from him and he gets caught up in a revolution, narrowly escaping a firing squad and becoming aide to General Alcazar. When the general turns on Tintin, Tintin flees into the jungle to the tribe that made the fetish, and learns that it has a hidden diamond. Tracking the fetish to a homebound ship, Tintin struggles with thieves until the fetish breaks. Diamond and thieves are lost at sea, and he returns the broken artifact to the museum.
