This article aims at studying Simenon's colonial novel Le Coup de lune, through the question of the gaze. We will study how Simenon gradually brings the main character and those around him closer together. Far from focusing on the differences, the approach chosen by Simenon seems analogous. In fact, the character is defined not by its particular characteristics, but its similarities to the others. This refusal of exoticism in a colonial context gives to the text an ideological dimension, reflecting the connection between the characters, but also the link between the text and the collective imagination. Je est un double provides that the concept of marginality, strangeness, a theme particularly dear Simenon, is not forgotten. It shows constant swerving between the need to be connected to the group and the narcissistic posture that encourages the character to affirm its identity and set himself apart in a colonial environment.
