J.'s.
He was at home. I returned him the keys, told him that my curiosity was
sufficiently gratified, and was about to relate quickly what had passed,
when he stopped me, and said, though with much politeness, that he had
no longer any interest in a mystery which none had ever solved.

I determined at least to tell him of the two letters I had read, as well
as of the extraordinary manner in which they had disappeared, and I then
inquired if he thought they had been addressed to the woman who had died
in the house, and if there were anything in her early history which
could possibly confirm the dark suspicions to which the letters gave
rise. Mr. J---- seemed startled, and, after musing a few moments,
answered, "I am but little acquainted with the woman's earlier history,
except, as I before told you, that her family were known to mine. But
you revive some vague reminiscences to her prejudice. I will make
inquiries, and inform you of their result. Still, even if we could admit
the popular superstition that a person who had been either the
perpetrator or the victim of dark crimes in life could revisit, as a
restless spirit, the scene in which those crimes had been committed, I

to sink into a deep sleep, from which you could not awake me, but in
that sleep could answer questions with an accuracy which I could not
pretend to when awake--tell you what money you had in your pocket--nay,
describe your very thoughts--it is not necessarily an imposture, any
more than it is necessarily supernatural. I should be, unconsciously to
myself, under a mesmeric influence, conveyed to me from a distance by a
human being who had acquired power over me by previous _rapport_."

"But if a mesmerizer could so affect another living being, can you
suppose that a mesmerizer could also affect inanimate objects: move
chairs--open and shut doors?"

"Or impress our senses with the belief in such effects--we never having
been _en rapport_ with the person acting on us? No. What is commonly
called mesmerism could not do this; but there may be a power akin to
