The Seven Crystal Balls Hardcover

A sinister mystery unfolds in "The Seven Crystal Balls," the thirteenth volume in Hergé's classic Adventures of Tintin series, as the members of an archaeological expedition returning from Peru begin falling into a mysterious coma, one by one. Each victim is found in the presence of shattered crystal balls, and the only common link is their involvement in excavating the tomb of the Inca mummy Rascar Capac. Tintin and Captain Haddock find themselves caught in the escalating peril, especially when their friend Professor Calculus is also struck down, leading them on a desperate quest to unravel the ancient curse and rescue their companions from an unknown, powerful force connected to the enigmatic Inca civilization.
