Again the low, silvery laugh came rippling from her lips. She let the book fall from her hands upon her lap, and leaned far back upon the couch.

"Why do you torment me so?" she asked. "I tell you I have no son." Again she laughed,—less sweetly than before. "Why do you torment me?"

"I do not want to torment you. I will leave you. Shall I come again?"

"Again?" she repeated, vacantly, as though not understanding. But as I stood beside her I moved a little, and I thought her eyes rested on the figure of the professor, standing at the other end of the room, and her face expressed dislike of him, while her answer to me was a meaningless repetition of my own word.

"Yes," I said. "Shall I come again? Do you like to talk Russian?" This time she said nothing, but her eyes remained fixed upon the professor. "I am going," I added. "Good-by."

She looked up suddenly. I bowed to her, out of habit, I suppose. Do people generally bow to insane persons? To my surprise, she put out her hand and took mine, and shook it, in the most natural way imaginable; but she did not answer me. Just as I was turning from her she spoke again.

"Who are you?" she asked in English.

"My name is Griggs," I replied, and lingered to see if she would say more. But she laughed again,—very little this time,—and she took up the book she had dropped and began to read.

Cutter smiled, too, as we left the room. I glanced back at the graceful figure of the gray-haired woman, extended upon her couch. She did not look up, and a moment later Cutter and I stood again in the antechamber. The professor slowly rubbed his hands together,—his gigantic hands, modeled by nature for dealing with big things. Mrs. North rose from her reading.

"I have an idea that our patient has recognized this gentleman," said the scientist. "This has been a remarkably eventful day. She is probably very tired, and if you could induce her to go to bed it would be a very good thing, Mrs. North. Good-evening."
