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later with a quantity of papers which proved to be an unpublished memoir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.
