“When I returned to the great gallery,” continued Rouletabille, “I saw no more of Monsieur Robert Darzac, and I was not to see him again until after the tragedy at the Glandier. Mademoiselle was near Mr. Rance, who was talking with much animation, his eyes, during the conversation, glowing with a singular brightness. Mademoiselle Stangerson, I thought, was not even listening to what he was saying, her face expressing perfect indifference. His face was the red face of a drunkard. When Monsieur and Mademoiselle Stangerson left, he went to the bar and remained there. I joined him, and rendered him some little service in the midst of the pressing crowd. He thanked me and told me he was returning to America three days later, that is to say, on the 26th (the day after the crime). I talked with him about Philadelphia; he told me he had lived there for five-and-twenty years, and that it was there he had met the illustrious Professor Stangerson and his daughter. He drank a great deal of champagne, and when I left him he was very nearly drunk. “Such were my experiences on that evening, and I leave you to imagine what effect the news of the attempted murder of Mademoiselle Stangerson produced on me,—with what force those words pronounced by Monsieur Robert Darzac, ‘Must I commit a crime, then, to win you?’ recurred to me. It was not this phrase, however, that I repeated to him, when we met here at Glandier. The sentence of the presbytery and the bright garden sufficed to open the gate of the château. If you ask me if I believe now that Monsieur Darzac is the murderer, I must say I do not. I do not think I ever quite thought that. At the time I could not really think seriously of anything. I had so little evidence to go on. But I needed to have at once the proof that he had not been wounded in the hand. “When we were alone together, I told him how I had chanced to overhear a part of his conversation with Mademoiselle Stangerson in the garden of the Élysée; and when I repeated to him the words, ‘Must I commit a crime, then, to win you?’ he was greatly troubled, though much less so than he had been by hearing me repeat the phrase about the presbytery. What threw him into a state of real consternation was to learn from me that the day on which he had gone to meet Mademoiselle Stangerson at the Élysée, was the very day on which she had gone to the Post Office for the letter. It was that letter, perhaps, which ended with the words: ‘The presbytery has lost nothing of its charm, nor the garden its brightness.’ My surmise was confirmed by my finding, if you remember, in the ashes of the laboratory, the fragment of paper dated October the 23rd. The letter had been written and withdrawn from the Post Office on the same day.
