The same thought had crossed my own mind. It was not as if the Barrymores had taken us into their confidence. Their secret had been forced from them. The man was a danger to the community, an unmitigated scoundrel for whom there was neither pity nor excuse. We were only doing our duty in taking this chance of putting him back where he could do no harm. With his brutal and violent nature, others would have to pay the price if we held our hands. Any night, for example, our neighbours the Stapletons might be attacked by him, and it may have been the thought of this which made Sir Henry so keen upon the adventure.
"I will come," said I.
"Then get your revolver and put on your boots. The sooner we start the better, as the fellow may put out his light and be off."
In five minutes we were outside the door, starting upon our expedition. We hurried through the dark shrubbery, amid the dull 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 God, what's that, Watson?"
"I don't know. It's a sound they have on the moor. I heard it once before."
It died away, and an absolute silence closed in upon us. We stood straining our ears, but nothing came.
"Watson," said the baronet, "it was the cry of a hound."
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.
"What do they call this sound?" he asked.
"Who?"
"The folk on the country-side."
"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 hound. My God, can there be some truth in all these stories? Is it possible that I am really in danger from so dark a cause? You don't believe it, do you, Watson?"
"No, no."
"And yet it was one thing to laugh about it in London, and it is another to stand out here in the darkness of the moor and to hear such a cry as that. And my uncle! There was the footprint of the hound beside him as he lay. It all fits together. I don't think that I am a coward, Watson, but that sound seemed to freeze my very blood. Feel my hand!"
It was as cold as a block of marble.
"You'll be all right to-morrow."
"I don't think I'll get that cry out of my head. What do you advise that we do now?"
"Shall we turn back?"
"No, by thunder; we have come out to get our man, and we will do it. We after the convict, and a hell-hound, as likely as not, after us. Come on! We'll see it through if all the fiends of the pit were loose upon the moor."
We stumbled slowly along in the darkness, with the black loom of the craggy hills around us, and the yellow speck of light burning steadily in front. There is nothing so deceptive as the distance of a light upon a pitch-dark night, and sometimes the glimmer seemed to be far away upon the horizon and sometimes it might have been within a few yards of us. But at last we could see whence it came, and then we knew that we were indeed very close. A guttering candle was stuck in a crevice of the rocks which flanked it on each side so as to keep the wind from it and also to prevent it from being visible, save in the direction of Baskerville Hall. A boulder of granite concealed our approach,and crouching behind it we gazed over it at the signal light. It was strange to see this single candle burning there in the middle of the moor, with no sign of life near it—just the one straight yellow flame and the gleam of the rock on each side of it.
"What shall we do now?" whispered Sir Henry.
"Wait here. He must be near his light. Let us see if we can get a glimpse of him."
The words were hardly out of my mouth when we both saw him. Over the rocks, in the crevice of which the candle burned, there was thrust out an evil yellow face, a terrible animal face, all seamed and scored with vile passions. Foul with mire, with a bristling beard, and hung with matted hair, it might well have belonged to one of those old savages who dwelt in the burrows on the hillsides. The light beneath him was reflected in his small, cunning eyes which peered fiercely to right and left through the darkness, like a crafty and savage animal who has heard the steps of the hunters.
Something had evidently aroused his suspicions. It may have been that Barrymore had some private signal which we had neglected to give, or the fellow may have had some other reason for thinking that all was not well, but I could read his fears upon his wicked face. Any instant he might dash out the light and vanish in the darkness. I sprang forward therefore, and Sir Henry did the same. At the same moment the convict screamed out a curse at us and hurled a rock which splintered up against the boulder which had sheltered us. I caught one glimpse of his short, squat, strongly-built figure as he sprang to his feet and turned to run. At the same moment by a lucky chance the moon broke through the clouds. We rushed over the brow of the hill, and there was our man running with great speed down the other side, springing over the stones in his way with the activity of a mountain goat. A lucky long shot of my revolver might have crippled him, but I had brought it only to defend myself if attacked, and not to shoot an unarmed man who was running away.
We were both swift runners and in fairly good training, but we soon found that we had no chance of over taking him. We saw him for a long time in the moonlight until he was only a small speck moving swiftly among the boulders upon the side of a distant hill. We ran and ran until we were completely blown, but the space between us grew ever wider. Finally we stopped and sat panting on two rocks, while we watched him disappearing in the distance.
And it was at this moment that there occurred a most strange and unexpected thing. We had risen from our rocks and were turning to go home, having abandoned the hopeless chase. The moon was low upon the right, and the jagged pinnacle of a granite tor stood up against the lower curve of its silver disc. There,
