The Calculus Affair

Professor Calculus's friend develops a blue-skinned orange that can grow on any kind of land and survive harsh weather (in the manner of Lue Gim Gong) and therefore solve world hunger. The Professor and his friends, however, run afoul of gangsters who also covet the fruit. The adventure takes them from their home in Marlinspike Hall (Moulinsart), a fictional mansion that is presumably in Belgium, to Spain, where Calculus and another scientist are kidnapped.

After the death of Captain Thémistocle Paparanic, Captain Haddock's old friend, he inherits a ship called the Golden Fleece. Once Tintin and the captain arrive in Istanbul, where the ship is anchored, they meet Mr. Karabine, a businessman who stubbornly insists on buying it even though it is in a dilapidated state.

Intrepid young reporter, Tintin, and his loyal dog, Snowy, are thrust into a world of high adventure when they discover a ship carrying an explosive secret. As Tintin is drawn into a centuries-old mystery, Ivan Ivanovitch Sakharine suspects him of stealing a priceless treasure. Tintin and Snowy, with the help of salty, cantankerous Captain Haddock and bumbling detectives, Thompson and Thomson, travel half the world, one step ahead of their enemies, as Tintin endeavors to find the Unicorn, a sunken ship that may hold a vast fortune, but also an ancient curse.

When seven archaeologists find an ancient Inca temple, they become victims of an ancient curse.

Tintin and Captain Haddock are sent to guard Professor Calculus, who has invented a machine that can duplicate anything, and is staying in a village near the border of Syldavia and Borduria.

While on vacation in Egypt, Tintin encounters an eccentric archaeologist who believes to have found the whereabouts of Pharaoh Kih-Oskh's tomb. There Tintin finds a cigar marked with a strange emblem.
