In "The Red Pyramid," the narrator expresses a strong dislike for Desjardins after seeing his extravagant mansion located near the Tuileries. The opulence of the house deepens the protagonist's disdain for him, suggesting that wealth is associated with moral corruption. The mention of its location on rue des Pyramids underscores the mockery of Desjardins being an obvious, affluent antagonist.

Sadie, another character, comments on the street name's apparent irony, highlighting the absurdity of the situation. The narrator responds with a sarcastic remark, imagining that Desjardins might be too foolish to live on a street named in line with his character, indicating a theme of characterization through setting. This exchange reflects their mutual contempt for Desjardins and their sense of humor about their adversary.
