Gaston Leroux: The Mystery of the Yellow Room

CHAPTER 13: "The Presbytery Has Lost Nothing of Its Charm, Nor the Garden Its Brightness" (continued)

"Let us first go back to Monsieur Robert Darzac," said Rouletabille, calming me. "I have said that everything seems to be pointing against him. The marks of the neat boots found by Frederic Larsan appear to be really the footprints of Mademoiselle Stangerson's fiance. The marks made by the bicycle may have been made by his bicycle. He had usually left it at the chateau; why did he take it to Paris on that particular occasion? Was it because he was not going to return again to the chateau? Was it because, owing to the breaking off of his marriage, his relations with the Stangersons were to cease? All who are interested in the matter affirm that those relations were to continue unchanged.

"Frederic Larsan, however, believes that all relations were at an end. From the day when Monsieur Darzac accompanied Mademoiselle Stangerson to the Grands Magasins de la Louvre until the day after the crime, he had not been at the Glandier. Remember that Mademoiselle Stangerson lost her reticule containing the key with the brass head while she was in his company. From that day to the evening at the Elysee, the Sorbonne professor and Mademoiselle Stangerson did not see one another; but they may have written to each other. Mademoiselle Stangerson went to the Post Office to get a letter, which Larsan says was written by Robert Darzac; for knowing nothing of what had passed at the Elysee, Larsan believes that it was Monsieur Darzac himself who stole the reticule with the key, with the design of forcing her consent, by getting possession of the precious papers of her father - papers which he would have restored to him on condition that the marriage engagement was to be fulfilled.

"All that would have been a very doubtful and almost absurd hypothesis, as Larsan admitted to me, but for another and much graver circumstance. In the first place here is something which I have not been able to explain - Monsieur Darzac had himself, on the 24th, gone to the Post Office to ask for the letter which Mademoiselle had called for and received on the previous evening. The description of the man who made application tallies in every respect with the appearance of Monsieur Darzac, who, in answer to the questions put to him by the examining magistrate, denies that he went to the Post Office. Now even admitting that the letter was written by him - which I do not believe - he knew that Mademoiselle Stangerson had received it, since he had seen it in her hands in the garden at the Elysee. It could not have been he, then, who had gone to the Post Office, the day after the 24th, to ask for a letter which he knew was no longer there.
