"'Most extraordinary,' I said, and he nodded and looked 'round,
nervously.

"The policemen were pretty quiet, and I judged that they were feeling
rather worse than Wentworth; though, for that matter, you must not think
that I was altogether natural; yet I have seen so much that is
extraordinary, that I daresay I can keep my nerves steady longer than
most people.

"I looked over my shoulder at the men, and cautioned them, in a low
voice, not to move outside of the Barriers, _whatever happened_; not even
though the house should seem to be rocking and about to tumble on to
them; for well I knew what some of the great Forces are capable of doing.
Yet, unless it should prove to be one of the cases of the more terrible
Saiitii Manifestation, we were almost certain of safety, so long as we
kept to our order within the Pentacle.

"Perhaps an hour and a half passed, quietly, except when, once in a way,
the dogs would whine distressfully. Presently, however, they ceased even
from this, and I could see them lying on the floor with their paws over
their noses, in a most peculiar fashion, and shivering visibly. The
sight made me feel more serious, as you can understand.

"Suddenly, the candle in the corner furthest from the main door, went
out. An instant later, Wentworth jerked my arm, and I saw that the candle
before one of the sealed doors had been put out. I held my camera ready.
Then, one after another, every candle about the hall was put out, and
with such speed and irregularity, that I could never catch one in the
actual act of being extinguished. Yet, for all that, I took a flashlight
of the hall in general.
