This, then, was the explanation of the stealthy expeditions at night and the light at the window. Sir Henry and I both stared at the woman in amazement. Was it possible that this stolidly respectable person was of the same blood as one of the most notorious criminals in the country?
"Yes, sir, my name was Selden, and he is my younger brother. We humoured him too much when he was a lad, and gave him his own way in everything until he came to think that the world was made for his pleasure, and that he could do what he liked in it. Then as he grew older he met wicked companions, and the devil entered into him until he broke my mother's heart and dragged our name in the dirt. From crime to crime he sank lower and lower, until it is only the mercy of God which has snatched him from the scaffold; but to me, sir, he was always the little curly-headed boy that I had nursed and played with, as an elder sister would. That was why he broke prison, sir. He knew that I was here and that we could not refuse to help him. When he dragged himself here one night, weary and starving, with the warders hard at his heels, what could we do? We took him in and fed him and cared for him. Then you returned, sir, and my brother thought he would be safer on the moor than anywhere else until the hue and cry was over, so he lay in hiding there. But every second night we made sure if he was still there by putting a light in the window, and if there was an answer my husband took out some bread and meat to him. Every day we hoped that he was gone, but as long as he was there we could not desert him. That is the whole truth, as I am an honest Christian woman, and you will see that if there is blame in the matter it does not lie with my husband, but with me, for whose sake he has done all that he has."
The woman's words came with an intense earnestness which carried conviction with them.
"Is this true, Barrymore?"
"Yes, Sir Henry. Every word of it."
"Well, I cannot blame you for standing by your own wife. Forget what I have said. Go to your room, you two, and we shall talk further about this matter in the morning."
When they were gone we looked out of the window again. Sir Henry had flung it open, and the cold night wind beat in upon our faces. Far away in the black distance there still glowed that one tiny point of yellow light.
"I wonder he dares," said Sir Henry.
"It may be so placed as to be only visible from here."
"Very likely. How far do you think it is?"
"Out by the Cleft Tor, I think."
"Not more than a mile or two off."
"Hardly that."
"Well, it cannot be far if Barrymore had to carry out the food to it. And he is waiting, this villain, beside that candle. By thunder, Watson, I am going out to take that man!"
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
