Tikal 2

From the Publisher:
Tikal was discovered and explored during a very successful expedition led by Profs. Kramer and Kiesling. A decade later, a scroll is found that hints of a lost temple near the first site. This rumor rekindles their passion for Tikal and the two scientists start to discuss the prospect of another expedition to Central America. In the midst of their planning they encounter Profs. Braff and Pauchon at an international archaeology conference in Geneva, who want to know the truth about the enticing rumour.
