l moaning of the
autumn wind and the rustle of the falling leaves. The night air was
heavy with the smell of damp and decay. Now and again the moon peeped
out for an instant, but clouds were driving over the face of the sky,
and just as we came out on the moor a thin rain began to fall. The light
still burned steadily in front.

"Are you armed?" I asked.

"I have a hunting-crop."

"We must close in on him rapidly, for he is said to be a desperate
fellow. We shall take him by surprise and have him at our mercy before
he can resist."

"I say, Watson," said the baronet, "what would Holmes say to this? How
about that hour of darkness in which the power of evil is exalted?"

As if in answer to his words there rose suddenly out of the vast gloom
of the moor that strange cry which I had already heard upon the borders
of the great Grimpen Mire. It came with the wind through the silence
of the night, a long, deep mutter, then a rising howl, and then the sad
moan in which it died away. Again and again it sounded, the whole air
throbbing with it, strident, wild, and menacing. The baronet caught my
sleeve and his face glimmered white through the darkness.

My blood ran cold in my veins, for there was a break in his voice which
told of the sudden horror which had seized him.

"Who?"

"The folk on the countryside."

"Oh, they are ignorant people. Why should you mind what they call it?"

"Tell me, Watson. What do they say of it?"

I hesitated but could not escape the question.

"They say it is the cry of the Hound of the Baskervilles."

He groaned and was silent for a few moments.

"A hound it was," he said at last, "but it seemed to come from miles
away, over yonder, I think."

"It was hard to say whence it came."

"It rose and fell with the wind. Isn't that the direction of the great
Grimpen Mire?"

"Yes, it is."

"Well, it was up there. Come now, Watson, didn't you think yourself that
it was the cry of a hound? I am not a child. You need not fear to speak
the truth."

"Stapleton was with me when I heard it last. He said that it might be
the calling of a strange bird."

"No, no, it was a h
