I could see him only dimly. His shoulders were hunched
a little, his head forward; but though it was motionless, I knew that his
eyes were not. It is queer how one knows that sort of thing at times. The
police were just as silent. And thus a while passed.

"A sudden sound broke across the silence. From two sides of the room
there came faint noises. I recognized them at once, as the breaking of
the sealing-wax. _The sealed doors were opening._ I raised the camera and
flashlight, and it was a peculiar mixture of fear and courage that helped
me to press the button. As the great flare of light lit up the hall I
felt the men all about me jump. The darkness fell like a clap of thunder,
if you can understand, and seemed tenfold. Yet, in the moment of
brightness, I had seen that all the sealed doors were wide open.

"Suddenly, all around us, there sounded a drip, drip, drip, upon the

"Through some awful minutes the 'blood-drip' continued to fall in an

neck, you will know the sound--in miniature! Like lightning, the thought
sprang into my brain:--_IT has crossed the Pentacle._ For you will
remember that I had made one about each of the dogs. I thought instantly,
with a sick apprehension, of our own Barriers. There was something in the
hall with us that had passed the Barrier of the Pentacle about one of the
dogs. In the awful succeeding silence, I positively quivered. And
suddenly, one of the men behind me, gave out a scream, like any woman,
and bolted for the door. He fumbled, and had it open in a moment. I
yelled to the others not to move; but they followed like sheep, and I
heard them kick the candles flying, i
