> Chapter companion for The Mystery of the Yellow Room by Gaston Leroux.

## What happens

Rouletabille and Sainclair have breakfast at the Donjon Inn, where Rouletabille reveals that he is now certain the assassin will return that night, having deduced that Mademoiselle Stangerson is in communication with the murderer and is facilitating his entry. He recounts his earlier conversation with Robert Darzac, who admitted that both he and Mademoiselle Stangerson know the murderer's identity but refuse to reveal it. Rouletabille also spots Arthur Rance at the château, surprising him, and discusses the Berniers' release with them.
