"Good-evening," I said. Mrs. North made a slight inclination with her head, in answer to our salutation. I pushed aside the heavy curtain, and we went out. Cutter had a pass-key to the heavy door in the passage, and opened it and closed it noiselessly behind us. I felt as though I had been in a dream, as we emerged into the dimly lighted great hall, where a huge fire burned in the old-fashioned fireplace, and Fang, the white deerhound, lay asleep upon the thick rug.

"And now, Mr. Griggs," said the professor, stopping short and thrusting his hands into his pockets, "will you tell me what she said to you, and whether she gave any signs of intelligence?" He faced me very sharply, as though to disconcert me by the suddenness of his question. It was a habit he had.

"She said very little," I replied. "She said that 'Paul' was dead. Was that her husband's name as well as her son's?"

"Yes. What else?"

"She told me she had no son; and when I reminded her that she had seen him that very afternoon, she laughed and answered, 'I tell you I have no son,—why do you torment me?' She said all that in Russian. As I was going away you heard her ask me who I was, in English. My name appeared to amuse her."

"Yes," assented Cutter, with a smile. "Was that all?"

"That was all she said," I answered, with perfect truth. Somehow I did not care to tell the professor of the look I thought I had seen in her face when her eyes rested on him. In the first place, as he was doing his best to cure her, it seemed useless to tell him that I thought she disliked him. It might have been only my imagination. Besides, that nameless, undefined suspicion had crossed my brain that Madame Patoff was not really mad; and though her apparently meaningless words might have been interpreted to mean something in connection with her expression of face in speaking, it was all too vague to be worth detailing. I had determined that I would see her again and see her alone, before long. I might then make some discovery, or satisfy myself that she was really insane.

"Well," observed the professor, "it looks as though she remembered her husband's death, at all events; and if she remembers that, she has the memory of her own identity, which is something in such cases. I think she faintly recognized you. That flush that came into her face was there when she saw her son this afternoon, so far as I can gather from Carvel's description. I wish they had waited for me. This remark about her son is very curious, too. It is more like a monomania than anything we have had yet. It is like a fixed idea in character; she certainly is not sane enough to have meant it ironically,—to have meant that Paul Patoff is not a son to her while thinking only of the other one who is dead. Did she speak Russian fluently? She has not spoken it for more than eighteen months,—perhaps longer."

"She speaks it perfectly," I replied.

"What strange tricks this brain of ours will play us!" exclaimed the professor. "Here is a woman who has forgotten every circumstance of her former life, has forgotten her friends and relations, and is puzzling us all with her extraordinary lack of memory, and who, nevertheless, remembers fluently the forms and expressions of one of the most complicated languages in the world. At the same time we do not think that she remembers what she reads. I wish we could find out. She acts like a person who has had an injury to some part of the head which has not affected the rest. But then, she never received any injury, to my knowledge."
