Doctor Müller

Dr. J.W. Müller is a fictional character from the comic series The Adventures of Tintin, by Belgian cartoonist Hergé.

Müller is, like Rastapopoulos, one of Tintin's great adversaries. He first appears in The Black Island, where he plays a doctor and director of an asylum who is actually dedicated to leading an international gang of currency counterfeiters. After Tintin discovers him and ruins his plans, he settles in Khemed, a fictional country on the coast of the Red Sea. There he meets Tintin again in Tintin in the Land of Black Gold. Müller has grown a beard and acts as an agent for the oil company Skoil, which sells adulterated gasoline. He will kidnap Abdallah, son of Emir Mohammed Ben Kalish Ezab, to force him to act in favor of Skoil's interests. He is still in the Khemed when Tintin briefly sees him again in Coke Stock: the doctor has become a general in Sheikh Bab el Ehr's army.
