The Mystery of the Yellow Room · Chapter
Rouletabille Knows the Two Halves of the Murderer explained
Mademoiselle Stangerson is attacked a second time and left near death, though she survives with her mind affected.
What happens
Mademoiselle Stangerson is attacked a second time and left near death, though she survives with her mind affected. Robert Darzac arrives too late to prevent the assault. Rouletabille explains that his plans to protect her were foiled because he was drugged. The next morning, the magistrate arrives and arrests Darzac based on a railway employee's testimony that he was seen at Epinay-sur-Orge at the time of the attack. Darzac refuses to explain his whereabouts. Mademoiselle Stangerson cries out in despair as he is taken away. Rouletabille privately tells Darzac that he knows the murderer's identity—both halves—and vows to defend him.
