Diamond Crown of Yucatan

Diamond Crown of Yucatán follows two parallel stories that blend mystery and history: a contemporary story about an archeological expedition in Mexico and another story about Medieval Yucatán that goes back to 1519. In the present-day story Professor Cronin a great expert in ancient Maya civilization shares a heretical idea with his colleague Katrin: long before the Spanish invasion of Mexico in the 16th century the majority of Maya Indians lived under Christian laws. A thousand years ago Christianity was brought to them by their ancestors - the Tatars-Toltec. The Professor plans an archeological expedition to Cozumel to search for evidence to support his theory. He invites Katrin and her ex-boyfriend to join the expedition. Katrin is looking to have fun in Mexico and participate in the search for an ancient artifact - the Imperial Crown of Yucatán but she begins to suspect her ex-boyfriend in a double game. The day before the departure she discovers the murder of a member of the expedition.
