# XLV explained — Monsieur Lecoq

> Chapter companion for Monsieur Lecoq by Émile Gaboriau.

## What happens

Blanche de Courtornieu confronts Chupin about his negligence, then decides to spy on Marie-Anne herself. She forces Aunt Medea to accompany her to the Borderie, where she observes a man delivering something to Marie-Anne. After Marie-Anne leaves the cottage, Blanche enters and discovers a sumptuously appointed upper room, confirming her suspicions of Martial's affair. In a fit of jealous rage, she poisons a bowl of bouillon intended for Marie-Anne.

## Themes in this chapter

### Deception and Disguise

Blanche deceives Chupin with a show of generosity, then disguises her true intentions by spying at night. The Borderie itself is a facade of poverty hiding a luxurious love nest.

### Gender and Women's Roles

Blanche subverts expected feminine passivity by taking direct, violent action, while Aunt Medea is portrayed as a helpless dependent. The chapter explores women's agency within restrictive social roles.

### Appearance vs. Reality

The humble exterior of the Borderie contrasts sharply with the luxurious upper room, symbolizing the hidden truth of Martial and Marie-Anne's relationship.
