"It is a delicate matter," repeated Dr. Cutter. "In the first place, I must explain my own position here. I am an Englishman, devoted to scientific pursuits. Originally a physician, subsequently professor in one of our universities, I have given up both practice and professorship in order to be at liberty to follow my studies. I am often abroad, and I generally spend the summer in Switzerland or somewhere in South Germany. I was at Rugby with Madame Patoff's brother-in-law, John Carvel, whom I dare say you know, and I met Madame Patoff two years ago at Wiesbaden. I met her there again, last year, and this summer, as I was coming to the South, I found her in the same place,—little more than a month ago. In both the former years your brother Alexander came to visit her, on leave from St. Petersburg. I knew him, therefore, and was aware of her deep affection for him. This time I found her very much depressed in spirits because he had resolved to join you in Constantinople. Excuse me if I pain you by referring to him. It is unavoidable. One morning she told me that she had made up her mind to go to Turkey, traveling by easy stages through Switzerland to Italy, and thence by steamer to the East. She dreaded the long railway journey through Austria, and preferred the sea. She was in bad health, and seemed very melancholy, and I proposed to accompany her as far as the Italian frontier. We went to Lucerne, and thence to Como, where I intended to leave her. She chose to wait there a few days, in order to have her letters sent on to her before going to the East. Among those which came was a long letter from you, in which you told in detail the story of your brother's disappearance. Your mother was alone in her sitting-room when she received it, but the effect of the news was such that her maid found her lying insensible in her chair some time afterwards, and thought it best to call me. I easily revived her from the fit of fainting, and when she came to herself she thrust your letter into my hand, and insisted that I should read it. She was very hysterical, and I judged that I should comply with her request. The scene which followed was very painful."
"Well?" asked Paul, who was visibly agitated. "What then?" he inquired rather sharply, seeing that Dr. Cutter was silent.
"To be short about it," said the professor, "it has been evident to me from that moment that her mind is deranged. No argument can affect the distorted view she takes."
"But what is the view? What does she think?" inquired Paul, trembling with excitement.
"She thinks that you were the cause of your brother's death," answered Cutter shortly.
"That I murdered him?" cried Paul, feeling that his worst fears were realized.
"Poor lady!" exclaimed the professor, fixing his gray eyes on Paul's face. "It is of no use to go over the story. That is what she thinks."
Paul turned from his companion, and leaned against a tree for support. He was utterly overcome, and unmanned for the moment. Cutter stood beside him, fearing lest he might fall, for he could see that he was wasted with anxiety and weak with fatigue. But he possessed great strength of will and that command of himself which is acquired by living much among strangers. After a few seconds he stood erect, and, making a great effort, continued to walk upon the road, steadying himself with his stick.
"Go on, please," he said. "How did you come here?"
"You will understand that I could not leave Madame Patoff at such a time," continued the professor, inwardly admiring the strength of his new acquaintance. "She insisted upon returning northwards, saying that she would go to her relations in England. Fearing lest her mind should become more deranged, I suggested traveling slowly by an unfrequented route. I intended to take her to England by short stages, endeavoring to avoid all places where she might, at this season, have met any of her numerous acquaintances. I chose to cross the Splügen Pass to the Lake of Constance. Thence we came here by the Nagold railway. I propose to take her to the Rhine, where we will take the Rhine boat to Rotterdam. Nobody travels by the Rhine nowadays. You got my telegram at Vienna? Yes. Yours went to Wiesbaden, was telegraphed to Como, and thence here. I had just time to send an answer directed to you at Vienna, as a passenger by the Oriental Express, giving you the name of this place. I signed it with your mother's name."
