Tintin in the Land of Black Gold

Automobile engines were struck by a strange epidemic: they suddenly began to explode without any visible reason. Newspapers are clamoring about the disaster: shares of oil companies are rapidly falling, wells are closing, air transport is being halted due to poor fuel quality: Specialists are spending days in laboratories, but they cannot find an explanation for the mysterious phenomenon, as the methods of extracting and refining oil remained the same; samples of the fuel also yield nothing: So, could it be someone's malicious intent? If so, who is behind it? Tintin takes on the task of answering all questions and uncovering the mystery of the exploding gasoline. To do this, he gets hired as a radio operator on the tanker "Speedol Star," setting sail for the Kingdom of Khemis - the land of black gold.
