Seacht Mallacht Na Meallta Criostail (Tintin i Ngaeilge / Tintin in Irish)

A terrifying coma strikes seven scientists recently back from an expedition to the Andes in search of a royal tomb. Can this be the curse of the Inca gods? The only clue is the shattered crystal ball beside each of the victims. The mystery deepens when Professor Piocardach goes missing ? and only Tintin and Haileab- can track him down.
