While engaged in writing the story of Evelin Delorme it was my good fortune to make the acquaintance of Dr. Herbert L. Flint, the well-known hypnotist briefly referred to in chapter three. The science of Hypnotism being a theme of absorbing interest to me, I eagerly availed myself of the opportunity thus offered for exhaustive investigation of the subject, and was accorded frequent and prolonged interviews with Dr. Flint. During one of these I reviewed to him briefly the outline of my story and the strange mystery of Evelin Delorme which had given rise to the plot. I saw at once that he was unusually moved and interested. At my conclusion he arose hastily and left the room, returning a moment later with a quantity of papers which proved to be an unpublished memoir which he was then preparing. From this he hurriedly separated several sheets and placed them in my hand, remarking with suppressed feeling, "Here is the missing link in your narrative."
He has allowed me to publish it here in his own words.EXTRACT FROM THE UNPUBLISHED MEMOIRS OF DR. FLINT.
"The following is a brief account of a very curious case of hypnotic suggestion, and one which, because of the mystery surrounding its final outcome, has caused me no little anxiety.
"On the 9th of July, 1878, there came to my office in St. Louis a strikingly beautiful young woman of evident wealth and aristocratic breeding, who gave her name as Eva Delorme. Her dress indicated recent bereavement, and her face impressed me as being that of one whom death had deprived of all those near and beloved. She stated her errand at once, and briefly. She had been pursuing the study of Mesmeric Sciences, and, believing herself a good hypnotic subject, desired that I make a trial with that end in view. A simple test convinced me that she was susceptible to hypnotic suggestion, and further experiment revealed to me that she was one of the most perfect subjects I have ever known. She called again the day following and asked me if it were possible, through the aid of hypnotism, to give to her a double personality; adding that she desired to become for a few hours a heartless, haughty, gay woman of the world—precisely opposite, in fact, to what she really appeared. Believing that she wished to forget her sorrow for a time, I assured her that I thought this might be accomplished and that it would probably obliterate all knowledge of a previous existence for the time being. To this she eagerly consented, and after some further conversation concerning the details I asked her what name she desired to assume in her new character. She replied that her full name was Evelin March Delorme, of which, in her assumed personality, she would retain the first two. She likewise gave me a memorandum of a street and number to which she was to be directed; this being, doubtless, one of several of her dwelling properties, for she impressed me always as a person of abundant wealth. With a few passes I then placed her under the hypnotic influence, and while in this state I impressed upon her earnestly the fact that she would awaken a haughty and heartless woman of the world, dashing and gay, free from past regrets and future misgivings, as she had told me to do....
