all of it can be
cleared up, but I see no way of going past the thing we heard at the last
and the fear that Parsket showed.

"His death--no, that proves nothing. At the inquest it was described
somewhat untechnically as due to heart spasm. That is normal enough and
leaves us quite in the dark as to whether he died because he stood
between the girl and some incredible thing of monstrosity.

"The look on Parsket's face and the thing he called out when he heard the
great hoof sounds coming down the passage seem to show that he had the
sudden realization of what before then may have been nothing more than a
horrible suspicion. And his fear and appreciation of some tremendous
danger approaching was probably more keenly real even than mine. And then
he did the one fine, great thing!"

"And the cause?" I said. "What caused it?"

Carnacki shook his head.

"God knows," he answered, with a peculiar, sincere reverence. "If that
thing was what it seemed to be one might suggest an explanation which
would not offend one's reason, but which may be utterly wrong. Yet I have
thought, though it would take a long lecture on Thought Induction to get
you to appreciate my reasons, that Parsket had produced what I might term
a kind of 'induced haunting,' a kind of induced simulation of his mental
conceptions to his desperate thoughts and broodings. It is impossible to
make it clearer in a few words."

"But the old story!" I said. "Why may not there have been something
in _that_?"

"There may have been something in it," said Carnacki. "But I do not think
it had anything to do with this. I have not clearly thought out my
reasons, yet; but later I may be able to tell you why I think so."

"And the marriage? And the cellar--was there anything found there?"
asked Taylor.

"Yes, the marriage was performed that day in spite of the tragedy,"
Carnacki told us. "It was the wisest thing to do considering the things
that I cannot explain. Yes, I had the floor of that big cellar up, for I
had a feeling I might find something there to give me some light. But
there was nothing.

"You know, the whole thing is tremendous and extraordinary. I shall
never forget the look on Parsket's face. And afterward the disgusting
sounds of those great hoofs going away through the quiet house."

Carnacki stood up.

"Out you go!" he said in friendly fashion, using the recognized formula.

And we went presently out into the quiet of the Embankment, and so to
