This story of remarkable power and brilliance dealing with a weird and most unfamiliar situation in hypnotism. 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conclusion he arose hastily and left the room, returning a moment later with a quantity of papers which proved to be an unpublished memoir which he was then preparing.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.
