THE SEVEN CRYSTAL BALLS. Seven explorers are home from Peru, among their trophies is the mummy of Rascar Capac, looted from an Inca tomb. One by one the explorers are struck by a mysterious illness, and beside each lie the fragments of a crystal ball. Tintin and Captain Haddock are soon involved. They learn of the ancient curse upon those who violate the Inca's tomb. Then, one night, the mummy vanishes; later, Professor Calculus is kidnapped. Tintin, Snowy and the Captain take up the chase in the first part of a remarkable South American adventure. PRISONERS OF THE SUN. Tintin, Snowy and Captain Haddock have a kidnapping on their hands. Professor Calculus has vanished. His disappearance is certainly connected with an ancient curse of the Incas, and the trail leads to Peru. But everyone fears the vengeance of the Prince of the Sun and only Zorrino the young orange-seller, will help them. High into the Andes they go, but the perilous journey ends in a dungeon and the prisoners face a hideous end. In this sequel to THE SEVEN CRYSTAL BALLS Tintin is involved in one of his strangest and most colourful adventures.
