Jacobs seeks to introduce a familiar aspect in the scenery of science fiction, giving a very pleasant illusion of realism in his fantastic scenarios. La Marque Jaune (The Yellow M), located in the atmosphere and fog of London, is his masterpiece.
Jacobs's stories have the same basic elements as the pre-war horror movies: a monster with unlimited powers, innocent victims, the mad scientist, the threat to humanity. The malefic μ mark left by the criminal in La Marque Jaune is inspired by Fritz Lang's M (or more directly by Hergé's Cigars of the Pharaoh). It is hard not to see an influence from Agatha Christie in the successive disappearances from a small group at the beginning of the same story.
On March 14 in Paris, Christie's sells the original art of plate 8 of La Marque Jaune, lot 69 estimated € 100K. This drawing 34 x 45 cm in black ink and graphite heightened with gouache includes the code numbers for the subsequent filling of the phylacteries. It was published in November 1953 in Le Journal de Tintin and in 1956 in the album.
The action is intense throughout the story and this plate is no exception. It includes the atmosphere of a London street, the two good heroes, some police officers, and even the scanning eye of a lesser character for that point in the story who will be later identified as the scientist executing the remote manipulating of the brain of the creature.
