Just as Alfred Hitchcock made furtive appearances in his films, Hergé couldn’t resist joining in the adventures of his characters. He discreetly drew himself into the scenery, appearing as a reporter dutifully taking notes when Tintin embarks for the Congo, or interviewing a local in front of the gates to Marlinspike Hall, in hope of gaining the latest on the story of the broken glass in The Calculus Affair. In Hergé’s universe, it’s hard to find a character that has been created from scratch: most were inspired by real people who were either close to the author in some way, historical figures or celebrities at the time.
