"I am conscious of not having eaten for a long time," answered Paul. "I suppose I was too much excited to be hungry before."
"You are not excited any longer?" inquired Dr. Cutter, with a smile.
"No. I believe I am perfectly calm. I have accomplished the journey, I have seen my mother, I have heard her last word, and I shall go to Persia to-morrow."
"Your programme is a simple one," answered his companion. "However, I am sure you can be of no use here. Your mother is quite safe under my care."
"It is my belief that she would be quite safe alone," said Paul, "though your presence is a help to her. You are a friend of her family, you knew my poor brother, you are intimate with my uncle by marriage, Mr. John Carvel. I am sure that, since you are good enough to accompany my mother, she cannot fail to appreciate your kindness and to enjoy your society. But I do not think she really stands in need of assistance."
"That is a matter of opinion," replied the professor, sipping his wine.
"Yes; but shall I be frank with you, Dr. Cutter? I fancy that, as a scientist and a student of diseases of the mind, you are over-ready to suspect insanity where my mother's conduct can be explained by ordinary causes."
"My dear sir," said the professor, "if I am a scientist, I am not one for nothing. I know how very little science knows, and in due time I shall be quite ready to own myself mistaken, if your mother turns out to be perfectly sane."
"You are very honest," returned Patoff. "All I want to express is that, although I am grateful to you for taking her home, I think she is quite able to take care of herself. I should be very sorry to think that you felt yourself bound not to leave her. She is fifty-two years old, I believe, but she is very strong, though she used to fancy herself in bad health, for some reason or other; she has a maid, a courier, and plenty of money. You yourself admit that she has no delusion except about this sad business. I think that under the circumstances she could safely travel alone."
"Possibly. But the case is an interesting one. I am a free man, and your mother's age and my position procure me the advantage of studying the state of her mind by traveling with her without causing any scandal. I am not disposed to abandon my patient."
